Having worked on antenna projects at home and with good weather the urge to get out and get on the air was strong ! This time it was an morning outing to the New Forest and Bolderwood, which was unsuprisingly busy with familes, dog walkers and folk enjoy the lovely surroundings of Bolderwood.
New Forest map in Bolderwood
I setup the 705 and Alexloop, although struggled with getting the loop on securely this time out, just figured it was a case of over familairity – sometimes it just goes ‘on’ but this time it was being a right rascal ! Still, i was on the air quick with the radio setup. I jumped on 20m and started with FT8. No sooner had I self spotted the flow of contacts coming in was amazing !
In no more than 30 minutes the 10 contacts to activate the park was complete – even with a pile up !
The FT8 contacts came in from all over Europe, I was making it into the west coast of the states, but no QSO’s that far today unlike last weeks greyline activation.
FT8 on 20m – great reach with the magloop and 10W of power.
With the 10 contacts needed to activate the park and enough battery for both laptop and radio I tried SSTV, but it was very busy today. I found it slightly annoying that some people seem to serial transmit and dont leave a gap for a response. At least two times there was the same person calling CQ without leaving a gap and just retransmitting, I did however manage to capture a screenshot thanks to the cool CQ SSTV website which pulls in reception of SSTV sites.
received in NL on 10W
I tried a couple of times, but the QRM from interference on the band, as seen by the horiziontal lines on the image, was just getting stronger. I jumped over to 17M being a non contest band and generally good for QRP operations.
My first attempt on the QRP CoA resulted in a partial call sign and no signal report, so I moved further up the band to find a gap. I wasnt to be disappointed and made 3 great telephony contacts on 10W, it was a great experience mix up the PoTA activation with SSB phone contacts, with good reports.
3 Telephony contacts on 17m – DM5MU booming in on 3W
It was great that two of the phone contacts where made my PoTA hunters, showing that the app really worked well. Getting pulled out using low power is a challenge, but great when those signal repots come and the QSO’s are more than the FT8 signal report/ACK. A fine example of this was the SO with ‘Andy’ and DM5MU, who was happy to chat about his amazing Yagi which was running very low power but booming into the new forest with 59+10db! My signal reports was just as good with 5/9!
With all the fun and excitment of making rapid contacts on FT8 and Phone contacts on 17M I felt i had a great time on the radio, I was able to at least get a SSTV decode and enjoyed doing PoTA – one award is the ‘repeat offender’ which is 25 activations from the same location. As the new forest is quite big, its possible to goto other parts and use the same PoTA reference, so something I’m most deifneatly lookin at doing as the year goes on !
Thanks to the PoTA Hunters ! Esp on Telephony ! 🙂
A big thanks to the PoTA huters, esp those who work me whilst I’m only running 10W and patiently give me their callsign and signal reports, it really is a great time out !
Some lovely sun kept the chills off today with flowers blooming and when it reach mid afternoon looked like turning into a great afternoon evening, I thought it would be great to make an impromptu visit to Bolderwood to try a PoTA activation.
compare to Janurary temptures, I was basking in the winter sunshin at a 12 celsisus !
I had everything packed away, i did one quick check for the power beiing packed, which it was, but had no idea on the battery level of the laptop, I knew I had used it recently so it shouldnt be too low. I headed off and it was great to to Bolderwood which whilst still pleasently busy, didnt feel over crowded. I’m sure this will change even by the end of the month !
Setup in no timeblue skysa great place to do radio and relax
I was on the air in no time, with the Alexloop attached to the bench with a bungie and hooked into the IC705, it was easy to tune into 30m to start with for FT8. I chose 30m as I had alot of contacts at home and its not a band I used /P for POTA before, I made 4 contacts within 10 minutes, so wasnt disappointed. I then moved to FT4 on 20M – it was *busy* even finding a gap in FT4 was getting tricky, but I was glad to find a gap and get out. The laptop was down to 40% power by now, so I stuck it in energy efficent mode, which kept the battery going without issue and no adverse effect on the radio/USB connection.
using the laptop energy efficeint mode to extend the life the laptop
I was pleased with a series of rapid FT4 QSOs on 20m, i later learned these where all PoTA Hunters – whilst I’m amazed by them all in the distance, ranging from Austria and Spain in Europe, it was the DX contact with KC1MMC that blew me away – 3217 miles on 10W of power on a mag loop, I was really happy to say the least.
Sun went down and 20M opened up more
As the sun went down the volume of QSO’s on 20M just kept rolling in, from 17:17 to 17:25 I was having a QSO on FT8 every 2 minutes ! I had to call it a day as it was getting dark and wanted to get my equipment put away safely, but I think I enjoy coming out at dusk – maybe a small lamp or pen-light will be worth bringing next time.
14 contacts, 5 POTA hunters made happy !
This was a really enjoyable PoTA outing with minimal planning, I was really impressed how well the antenna done and the PSK Reporter picture shows, it can really reach the entire planet !
Digital modes doing really on 10W of power
I have seen videos of great QRP Contacts and am wondering how well I would do, I really think I should give it a try the next time I am out as the setup really impresses me and think it should be good to make some telephony contacts.
I’ve been making monthly updates to my webtechnologies site, which last month I got back up and running so the code would scrape the data from the ‘updated’ WSPR old-db. I’ve now added sections that allow filtering by band. This is all transmitted via the 6BTV which is doing an excellent job of getting out on all 6 bands it is setup for.
Webtechnologies site – now with spots per band functionality.
I’m aiming to keep building more features for the website each month, just small incremental changes, but I’m sure will keep adding making for a feature-rich site. There is so much that can be done with WSPR data, I really enjoy using this mode and its great ot use my programming skills for amateur radio also. Check it out at the webtechnologies site.
With another bright but cold day, it was a good time to get out and get on the air. This time I was packing my trust Alexloop Ham pack antenna along with the IC705, determined to make an activation on my 3rd attempt from Bolderwood.
WX – I caught the ‘warmer’ part of the day at round 9 to 7 celsius
I was no sooner out the car and onto one of the many available benches and quickly setup. The alex loop was out the bag and with a bungee hook strapped pretty tightly to the bench. I tuned for 20m and got a great SWR of between 1.3 and 1.4 but no more than 1.5 and 10W of power. The FT8 contacts came rolling in, and with a busy 20m FT8 was then onto FT4, for even quicker overs.
Alexloop SetupManual Logging
It was great to get a mobile phone signal as I tethered my laptop to the phone wifi and could upload my contacts directly to QRZ via the excellent grid tracker application, I still kept a manual log so it would be easy to confirm the order and QSO’s I had today. The Reverse Beacon Network and POTA app was doing me a great service, as quite a few of my contact were POTA hunters. Getting 10 contacts in under an hour was great given just how cold it was, it was nice to see 5 of the contacts are POTA hunters.
I gave SSTV a go, but the signal where coming in thick and fast, I started to see a response to my transmission, but another station came in over the top. I try to use Robot72 and BW12 to keep my over time on 14.2300 short, but most people dont QSY on SSTV, and even then we tend to get other people talking over the SSTV CoA on 20m as well..
Still, having uploaded my ADIF file from WSJTX to POTA I was soon awarded my 2024 activation. Just in the nick of time ! A good start to POTA in 2024 !
POTA 2024 Award – a good start to the year
I am really excited about getting out and do more POTA – its a great start to the year !
So with new choke packed away and bringing the battery pack, i headed out to Bolderwood in the New Forest, arriving at around 10:15, it was still pretty quiet and I had pick of parking spaces and benches.
bolderwood on New Years Day 2024
I then setup the IC705 with the Toybox antenna and radials, which I found getting the radials out much easier this time. I was able to get the SWR down on 17m to a 1.6~1.7.
SWR less todayradial spreadmuch easier than yesterday
With the antenna setup I then connected the 705 without the MAT Tuner to start with, having the large battery with me was really good as it support the LC IC705 bag nicely keeping the antenna and bag vertical. I then went about attachign the choke-wound usb cable to the laptop.
Uh oh.. this doesnt look good
As soon as the USB cable was attached, the QRM returned ! I could hear the FT8 stations coming into WSJTX without problem, but again when hitting transmit, the audio disconnected. Whilst the QRM was much reduced, there was no doubt it USB cable and laptop was still effecting the radio. I went ahead and the MAT autotuner, to see if that improve the situation, i.e. would it act as any kind of choke between the radio and antenna.
MAT Tuner working greatcould I try a choke hereWill I ever make a contact ?
The introduction of the MAT Tuner had no effect on the QRM, although I could see that with the longer coax between the tuner and antenna, I could potentially try putting chokes on here also. I disconnected the radio and just tried calling CQ on 17m QRP frequency, but to no avail. I could pull in signals and I tried jumping on the back on other QSO’s but think I wasnt getting out at all with the little whip antenna.
So I think whilst I have other options, I will explore those as well, I have always done well with the magloop, and its a great antenna, but the one I really want to try is the UK Antenna 40M EFHW, but currently my SOTA Beams mast is damaged from its first and only outing. I explored the website and was able to order the 3 replacement broken parts, which only cost £17.28 with 1st class postage.
The 40M EFHW UK Antenna – the next one to try when the replacement mast parts arrive…
I will continue experimenting with chokes and the Toybox antenna at the QTH before going back out with it again, I think with enough power, it would work well as a portable antenna, with QRP/10W,its giong to be hard work to get on the air with it…
So a quick update, having received the 5M USB cable and cable ties, i then went on to test out the choke method to reduce/remove the inteference from the IC705 as shown by Temporarily Offline Ham Radio video included yesterday.
toride and USB cable wrapquite a few turnsNo interference on IC705
The RF Choke comes from here, as I dont suffer RF back into the shack thanks to the EFHW and RF Choke on the feedline, the PSU Choke was not being used. Winding the toride was made quite easy by the fact the choke can be opened up and wound up, once secured with a a couple of cable ties it was easier to put the turns into specifc locations, tighten the cable wraps up, then cut off the excess.
WSJTX in action – no sign of disconnects or loss of audio
I tested MMSTV and WSJTX into the 2M Comet Whip antenna, everything worked fine with no issue of disconnected audio or interference into the radio or the computer. I’m looking forward to taking the setup out and trying again with the Toybox whip antenna to see how it does this time out.
Testing the IC705 with the RF Choke USB cable and laptop with MMSTV and WSJTX
So having got everything ready and with the weather, whilst chilly, was ok to go and venture out with the radio. I scheduled on the POTA activation website, and headed off to the New Forest to Bolderwood.
The drive in the Hyundai i10 was fine after its recent service, and was good to stretch its legs on the lively A roads in the area. For a small car its got a decent enough poke to make the journey without issue, as I was just carrying my IC705 and a few drinks.. I did notice I had left my ‘large’ battery behind – so I would be running real QRP from the 705’s internal battery and limited to 5W – still, i was nearer bolderwood than I was home, so pressed on.
radials on the floorradial connection to toyboxSWR 2:1 without ATU
I de-tangled the the 30 meters of radials, this took me a little while, but nethertheless wasn’t too problematic, the ends of the radials have a nice round terminator which makes de-tangling more a case of pulling the cables thru, rather than unpicking a ‘rats nest’ of wire (plenty of experience with the DX Commander and radials there!!!) I used the rig expert on 17m got the SWR across the band down to 2.1:1, which for a compromise antenna was ok.
FT8 RX 100%TX = ooopspulsating TX
I hooked up the laptop via Wfview, Virtual Comport and WSJTX. Signals came in no problem at all, and decodes appearing in WSJTX without issue. I then tried to TX, the SWR measurement was the same as the Rig Expert, but oddly the TX ‘pulsated’ as if it was getting disconnected. I went thru and checked the settings once more, no difference between home and here, only delta was the antenna. I tried the USB cable I had packed away to remove wifi/wfview/audio port as an issue, but the noise level went thru the roof! So I went back to trying to get wfview to work, at least at home on 2M I did get out (suprisngly!).
it was not to be my day to make an activation….
As I continued to try to connect, I checked PSK report on my phone – not a single RX. I could only put this down to the combination of the antenna and using wfview, as with a magloop and 5W on an ipad, I would at least get out, and as other POTA activations showed, worked without issue.
With 0 contacts and a slight piece of rain, i forgo the activation and headed home determinted to find out what I could do to solve my WSJTX TX issue.
TX issues with the 705 and using the Toybox antenna
Once home I searched around youtube and found several useful videos and this one demonstrated exactly the issues I faced when using my USB cable.
USB = QRM
With that I searched around the house, the longest USB cable I had was 2M long, and wouldn’t take many wraps of the toroids I have, so have ordered a 5M USB cable and some cable ties from Amazon, hopefully they will be here tomorrow, then I can try USB with a nice toroid to see if that removes the QRM.
a variety of ham specific toroids
I also thought that I should of tried with the ATU between the radio and antenna, as I think that would of also acted as a ‘common mode’ choke, but will try the USB route first as that looks the most promising solution at the moment.
Until next time (which is hopefully early in the new year) 73’s !
With getting reading to go POTA next step was to check the PC hardware, I previously used an apple tablet for IC705 wireless connectivity, but this lacks SSTV which I like to use. First step was to get my very old HP Pavillion laptop up and working with the IC705 !
First step was to retrack and setup the settings in the IC705, for this the first part of this video got the required settings. The app to control the radio here is Icom’s own, which I dont own a copy of, but it sets up the Wifi and necessary settings, also like that its a profile which can be easily loaded/unloaded.
setting up the IC705 for Wifi operation (first half applicable)
With the wifi setup correctly (I had to adjust the audio filter bandwidth and CI-V Echoback to OFF) I then set about setting up wfview, using this tutorial.
IC705, Wifi, VBAudio, Virtual COM port
This got me to the point whereby I could receive fine, but transmit didnt produce any audio, I rechecked the settings on the radio that Inputs/Connectors/Data MOD=WLAN and no issue there. I check wfview and the settings are correct, I did notice my version of wfview was 1.5, so check the forums, sure enough, others had the same problem and was fixed by an upgrade.
I downloaded the latest wfview and installed. I did notice this didnt overwrite the previous version, so I found the new version (C:\Program Files\wfview) and made a nice desktop shortcut, the registery settings had kept the config, so no need to re-enter all those thankfully.
I attached a Diamond RH770 2m/70cm antenna to the the 705 in the shack, just for something to transmit into, RX was flooded with QRM from all the computers and screens, but amazingly with 5W of power I was picked up by WESSEXSDR!
So.its now all looking good to use my oldlaptop with newer versions of wfview for at least WSJTX control. Hopefully just pointing MMSSTV and the virtual com port (10) and audio to VBAudio will get that working, but will wait until I have a HF antenna hooked up to test that ;o)
Its been quite some time since I’ve been out and done a Parks On the Air (POTA) activation, but with the year coming to an end and a bank holiday for a day off, it as good a time as any to get outside and get on the air !
The IC705, when used, has mostly be used in the shack. I tend to use it on the 6BTV antenna and keep the 7300 on the End-fed Half-Wave (EFHW) for SSTV and other digimodes.
At the moment my Mazda Bongo is awaiting a garage visit due to a poorly alternator (its 27 years old…) so I will be in the Hyundai i10 (to be my son’s car once he passes his test), hence I will be working /P !
Hyundai i10, compact and cheap to run!
I will be taking the IC705 in its LC192 bag, some may say that this is a branding gimmick, but this bag suits the 705 so well, its brilliant! I’m going to the extreme on portable option of using the Comet Toybox antenna. This antenna tends to get pretty slated, but when I’ve taken the time to set it up myself, found it works really well, even with QRP operation.
Toybox antenna
I’ve previously made a video of me using this from the QTH, showing how I tune and make a contact with it, but this will be my first time using it for a POTA activation.
IC705 and Toybox antenna in use
I’m getting all the parts together again, making sure that batterys and the mat705 ATU are good for operation.
MAT tuner charging via USBgigantic battery charging up
WX for around IO90
I’ll probably be heading for the New Forest, as there is plenty of places to park up and get the radio out, i’ll be logging old school pen and paper and using the upload feature once completed.
Hopefully the weather is kind to me and I get out, I have work to do on the eggbeaters still, and thats going well, but will put that in another post, for now, determined to get out with the radio and make some contacts!
With a second bank holiday in quick succession and the WX predictions for the bank holiday being ‘traditional’ I made a impromptu POTA activation in the New Forest. Whilst its not my nearest POTA, there are plenty of nice quite places to go, so I headed off for a evening of radio fun !
As is norm for me, I started out with FT8 – or should I say after some reacquainted got started with FT8 ! As I wanted to do SSTV I used my old laptop and USB cable. This has been running at home nicely for months for WSPR via the IC705/Laptop combo, sure enough, go out in the field and it starts playing up ! Firstly experienced disconnects on WSJTX on anything above 5W, and remembered that I had setup the 705 to be a 7300 to allow MMSSTV to use the same ‘hex codes’ – once I got the power and connection sorted, was soon on the air and the QSO’s started coming in. 17M was very busy but propagation good, the magloop and 5W was getting me all over the world, was very glad to see several contacts into the states from POTA hunters.
5W into magloop on 18 and 20m (FT8 / FT4)
I was soon getting drowned out on FT8 on 17m, so switched to 20M and FT4, whereby i was able to get the 10 QSO’s needed to activate the park. I then switched to SSTV. Receiving was fine, and the absence ‘noise’ produced fantastic RX. I thought I would give it a go, even tho I was ‘limited’ to 10W.
excellent QSO with OK1DNTMMSTV working well with the IC705enjoying POTA SSTV
A very good signal came in from OK1DNT and was reward with a 595 signal report on 10W ! I was overjoyed that the magloop, low power and noise floor worked so effectively. It really was a highlight for me and I think I shall work out how to the webcam on the laptop to capture some ‘live’ PoTA pictures, each time I’ve tried SSTV on PoTA, I’ve made a QSO, so it is most defineatly a viable mode with QRP power. Thanks to OK1DNT for the QSO as well !
I headed home with the Retevis RT73 working nicely doing its APRS positioning beaconing. Whilst the RT73 doesn’t have the TNC/Packet capabiilities of the THD7, it nethertheless does a great job of position reporting. I did struggle with updating the message, but I got it to read ‘POTA G’ I struggled to get numbers and symbols, so will investigate that next time. The RT73 is a ‘neater’ solution for 2m/70cm operation, tho admittedly I’ve not a QSO on it yet !
APRS via Retevis RT73 working well
En route i encountered the lovely horses/ponies of the new forest. I do love the nature and animals in the beautiful scenery.
RT73 and donkeyhaving a nibble on the grass
Once home and unloaded from the Bongo I set about logging. I always use a manual log, even for digitial modes, incase something should happen to the computer/device I used. I was pleased to see some very cool new features on the POTA website, in that its possible to create a manual log via the PoTA page for submission.
Manual logbeta model manual logadding the QSOs
I watched a video on how to do the manual log, shown below and it was easy to follow and create my own log submission.
POTA Manual Log Entry
Sure enough my log submission was done, it was so easy ! Also I could export the ADIF file and upload to QRZ
POTA ADIF to QRZ
Whilst the frequency and signal reports were not the ones from the event, it did at least have the time, band mode and contact, not bad at all and acertainly allot easier than when I first started POTA last year.
Overall, despite the early technical frustrations I really enjoyed this activation, it has made me think about a PoTA strategy for digital modes, i.e. use the mac ipad for FT8/FT4 and laptop for SSTV, if the ipad app had SSTV capabilitiy, that would be amazing, but its a great app as is being totally ‘wireless’. Still, I look forward to more PoTA as the year go on !
Its been quite some time since I’ve had the Alexloop Hampack, and with my QRP, /M and /P work becoming more ‘regular’ (at least one per month) – thought it time to share my views of this antenna system.
Alexloop hampack
Its hard to imaging, but its been just shy (April 2021) that I have had this antenna in my collection. This has given me plenty of opportunity to use it out in the field and for experimentation at home.
I bought this antenna to pair with the Icom IC705, which is undoubtedly an excellent transceiver in its own right – with excellent selectivity and filtering, its a question of putting the right antenna onto it.
The Alexloop Hampack – the good
Lets start what is good about the Alexloop Hampack. All these observations are based on my own usage, so whilst not scientific, they are at least practical and proven.
Its easy to setup
The Alexloop HamPack is very easy to setup. I can arrive at my operating destination and be on the air in minutes. There is no setting up a mast and throwing a wire, there is no tuning a vertical and getting the SWR 1:1 – i can get this antenna out the bag, onto a stand and tuned into the frequency I want to use very quickly. The LED showing the output might look a gimmick, but I can assure you I use this as a visual reference and then checking the radio’s SWR every time I setup or need to retune the antenna.
Its very selective
Now for some this might be a negative, but so far for me its been a positive. When I’m working /M or /P, I am limited to 10W. What I don’t want is to pick up every other station just slightlyoff frequency, and for sure, the AlexLoop gives me that. I can match my IC705 filters to the AlexLoop and get excellent input.
Its designed for and good at portable use
The AlexLoop Hampack bag is very well thought out. It comes with a excellent way of storing the main loop and then the tuner and other parts of the transceiver. I also own ICOM’s LC-192, which is an exemplary piece of portable radio design, however, even thou when I operate /M, I want to reduce the amount of baggage that I take, therefore I stick to using the Alexloop Hampack bag on its own, and regretfully the LC-192 is left at home ! With that, you can be sure if you *dont* have an LC-192 and are considering getting the Alexloop Hampack, the bag will suffice. It is not as good as the LC-192, in terms of access ports, padding and having a full functional HF/VHF/UHF transceiver system on your back, but for HF bands, the Alexloop Hampack bag *will get you on the air*
The bad
The price tag
It almost goes without saying, the biggest ‘bad’ of the Alexloop Hampack is the price tag. When I bought mine in April of 2021 it was £505, now an Alexloop Hampack will cost you up of £600. That is allot of money for an antenna and it really needs to justify its cost.
Using in the field
As I’ve said above, I found using the antenna in the field for QRP /P and /M incredibly good. However, not everyone is running an IC705, there are many /P or /M operators that have good transceivers that can push out 100W. The Alexloop is not designed for, and should never be used for values above 20W on SSB and 10W on Digital modes. If you have perfectly good transceiver already capable of powers above these, then is the AlexLoop Hampack the right antenna for you – I would say probably not, especially if you already own the transceiver, however, if you are designing a /P or /M solution from scratch, my answer would differ…
The Ugly
So is there anything ugly about a so well designed antenna. Well, I for one can say there is. When I received this antenna I found assembling it ‘awkward’ – that is getting the loop over the centre pole. This resulted in a nasty ‘nic’ getting into the loop coax.
I could easily accept this on a ‘cheap’ antenna with no instruction, but of an antenna, that at the time cost me £500+, I really was perturbed why a decent instructional video or document was available on how to set this antenna up. Furthermore, show how the selectivity worked would of been a benefit to a first time ‘loop’ user. Hindsite is 20/20, but when you pay allot you should really get that level of service included, not as an add-on.
Being an IC705 user, I found the Transceiver bag in the Alexoop Hampack to be oversized, compared to the afore mentioned LC-192, its padding/packaging for carrying a transceiver was really not as good as Icom’s own product. To me, this was scrimping on cost, rather than any other reason (i.e. a transceiver would fit in the bag) – and at the price-tag, was a little disappointing.
Summary / Recommendations
So its been nearly 2 years since I’ve had this antenna, I have at least 2 other antennas I can use with the IC-705 when working portable or mobile, and have the actual ICOM bag for the IC705, so what are my personal oonionsf the Alex Loop Ham Pack.
I am person that is time-poor, that is for me to go /P or /M requires planning and organisation, its not like I can just grab my radio and go out when I like, I’m busy. With that the Alex Loop Ham Pack always ensures that when I go out, I will get on the air – its easy to setup and I can make contacts as soon as the antenna and transceiver are matched. I don’t need to setup a mast, wire and ATU for an antenna, the Alex Loop Ham Pack does that for me with its simple and effective compact solution.
The biggest issue to me is the price, today (Jan 2023) it would cost me £600+ to get this antenna. That is a serious amount of money and given it is only capable of 20W maximum, is it the best antenna for the price ? I would say not, that a good dipole, end fed or vertical will outperform this antenna, but would it be as compact, easy and portable ? Probably not.
If you today you don’t have a QRP solution, you really cant go wrong with an IC705 and the Alexloop Hampack antenna, but then you are looking at a solution that is going to cost upward of £2000, to which you can get on the air with a QRP rig and antenna for £100-150 using a ubitx and simple dipole/end fed solution.
There is going to be a big difference in performance of the radios and antennas, and cost might be your personal motivation, where as quality/time maybe the secondary consideration.
Eitherway, the most important thing is to find the best solution you can afford, starting with the antennas as part of the solution, not the secondary, and getting outdoors and on the air.
