QRP POTA Bongo G-0079 12th Feb 22

Posted on February 12, 2022 by webmaster@hamradio.knipmeyer.co.uk

Having originally intending to go out on the 13th, the adverse weather and changes on planning on the home front made the 12th a better day to go. Whilst cold it was a great day to go out and try another park activation.

The park being activated today was G-0079 New Forest – Kingston Great Common National Nature Reserve. Another nice close park and after researching found a nice place to park up to operate from the Bongo.

Research position to operate from within the park boundary

For this activation attempt I wanted to use the Alex Loop Ham Pack antenna, as I had already used Toy Box antenna the previous week, and with the cold operating from the Bongo would be a good way to get on the air.

The Alexloop and Bike stand was really easy to setup, maybe even easier than the whip and radials, but it was quick to get on air. The bike stand held the alexloop no problem at all.

To start with I used the MAT-Tuner on 20M as I planned to do FT8 then SSTV, so I wanted to see if I can move about the band without re-dialling the magloop, in the end, I removed the MAT tuner and went to 30m. My SWR went up to 1.5 but was making more and more contacts.

By lunch time the QSO’s on 30m where coming in rapid succession, not quite a pile up, but enough to get the park activated. I also enjoyed a ‘rag-chew’ on 70cm via GB3IW, not for PoTA, but it was good to make a /M to /M contact whilst doing FT8 on HF. I also done a SSTV test from the my mobile location to back to the QTH, that came out quite well for 5W

SSTV on 2M received back home from G-0079

With it just being over midday and enough FT8 qso to activate the park, I tided up and headed back for a fantastic afternoon out with the station manager. We really enjoyed the afternoon out and the lovely views across to the IoW

In conclusion i can say that the Alexloop Ham pack antenna is amazing, its incredibly light and very easy to setup. The sensitivity of the dial is incredible, getting the SWR down low to 1.5 on 20M and 17M was no problem. I don’t think I will need an ATU with it, its better to dial it in and get the power into the antenna and a very small increase in reflected power back.

I really enjoyed doing PoTA, just getting out with the transceivers and making contacts is great fun, be it FT8, SSTV or Telephony, every time I go out, I am getting more experience and enjoy operating away from home more and more.

I am looking forward to my next PoTA activation and trying another antenna, hopefully the 40M end fed which I think will return the best results yet in terms of RF performance, but lets see…

PoTA – 1st Activation (G-0362) !

Posted on February 8, 2022 by webmaster@hamradio.knipmeyer.co.uk

It is done ! I have become part of PoTA History by activating Avon Heath Country Park (G-0362). There are plenty of other parks in the area and I’m really excited to continue my PoTA activities.

I have since reverted my Laptops OS back to Windows 10 – I found the USB Driver for Linux wasn’t working correctly with the IC705. Going to Windows and running the default Icom driver I found no issues at all ! This also means I am using recommended logging software for PoTA as seen in the video below.

N3FJP ACLog for POTA Activators

This will make logging much easier going forward.

I am planning to go out again 13th Feb 22 @ G-0079, which is quite near me and a familiar location to me.

QRP POTA G-0362 6th Feb 22

Posted on February 6, 2022 by webmaster@hamradio.knipmeyer.co.uk

So after a week away I decided to try my luck at Avon Heath Park (G-0362) again. This time I was determined to activate the park in any way I can with the IC705. I really wanted to prove the HFJ-350M toybox antenna was a viable portable antenna. With the Comet CGW-560 radials connected I have tuned it before at the QTH, but never out in the field, where anything and everything that can go wrong, will go wrong.

I had purchased a pop-up privacy tent, i had tested and set it up at home, it was really easy (of course). At Avon Heath I encountered two problems. High winds and very stoney ground. The pegs I had would of been fine on firm soil and no wind, but the winds kept the tent blowing away. With one huge gust my tent was gone but i captured it, only for one pole to snap ! I am hoping it can be repaired and used on other less windy trips. I will have to find some of the good ‘corkscrew’ pegs I have used camping before, but have mostly used up/used at home.

The ground at Avon Heath is very sandy, I’m not sure if its a good conductor or not, but I lay the radials over it as I had little alternative. I also found I had left a connector to allow using my rigexpert directly to the antenna at home. This was very frustrating as I was sure I had packed it ! I was able to tune the antenna using the IC705 in built SWR graph, and on 40M FT8 frequency got the SWR down to 2.0 – 2.5, whilst not ideal, it was at least workable.

I was able to check on-site using PSK Reporter that my signal was getting out good enough to be received – the above screen shot is from when I returned home. I did find the mobile app took some getting used to, but still workable (with gloves on !)

I spotted myself on the POTA app page and for 40M FT8, and sure enough I was getting quite a few contacts quite rapidly – not sure if it was because of POTA or just people making FT8 connections, I was just grateful to be making QSO’s on a very compromise antenna and relatively low power.

I had one major annoyance in that when my laptop booted up, the date on it was incorrect, thankfully I could quickly use the wi-fi on my iphone and sync my clock against rolex.ripe.net to get my time correct, however this would mean my 1st contact via WSJTX would need its log entry corrected.

I continued to stick with FT8, determined to activate, i had a great flurry of activity, then the longest time calling CQ, I think this must of been band conditions. When i was making QSO’s I would get to received signal report, but not the import RR or 73 to log it. This was really frustrating as both my computer and mobile phone battery where becoming depleted much quicker than anticipated. I only needed one more QSO to get the 10 needed to activate the park.

I turned on the THD7 and called CQ on 2M for POTA, thankfully and with much joy on my part I contact M7PBT and we quickly moved to 145.575 on 2M. I got a great 59+20 reception report from the higher location, and the final contact needed to activate the park !

I re-spotted myself to say I was going QRT as the weather was going decidedly southwards, so I packed up as quickly as I could, but ensuring there was nothing left behind and keeping the park tidy.

I know FT8 isn’t every ones ‘flavour’ but for me today, it done what I set out to do, activate the park. I also proved that the toy-box antenna is at least viable in data modes on 40m and was very easy to setup, just a case of laying out the radials.

I again with hindsight realised that I took way too much and my initial plan of just my backpack with the IC705 and my laptop would of been more than sufficient for todays digital operating. The backpack really proved its price tag in being strong, comfortable and able to take all my equipment and has space for the THD7 to clip on.

In the cold weather having a cup of coffee and boiled egg really kept me going and energized. I was annoyed at being out in the open with the IC705, I didn’t want to get it wet, but with light rain it was perfectly ok. I think a big poncho will be my best bet.

I did find my laptop was really lacking, the battery almost running out only after a few hours operation and the poor mouse control really shows how I’ve become a ‘touch here on the screen’ person now if I don’t have access to a mouse (laptop only has 1 USB port for IC705 connection). I think a Windows Tablet will help me allot with digital modes and logging software.

My other main learning was that the logging software I had come to depend on wasn’t very good, in its 2nd outing it messed up the log files, resulting in me having to manually craft them. PoTA only except ADIF format, whilst text readable and not binary, can be edited. In my case I had to add my 2M QSO to the WSJT-X export.

I’m awaiting confirmation of my activation but again have learned a huge amount and had a fantastic time out. I want to do at least one activation a month, so am looking for another nearby park which has yet to been activated. PoTA is addictive !

QRP POTA G-0362

Posted on January 29, 2022 by webmaster@hamradio.knipmeyer.co.uk

So today was my first Parks on the Air. Armed with the IC705, THD7 and a variety of antennas I set out early from the QTH. The morning walk with Sweety told me it was a cold day, but mild for January, I still wrapped up warm tho.

I had 3 bags of equipment, but the trolley handled it really well, making it quite easy to get to the location I had planned. I started setting up the end-fed antenna, but sadly my enthusiasm got the better of me and ended up snapping the mast when pulling it up ! I quickly setup on the loop and the THD7 on 2M and was pulling in signals from both. It wasn’t a long wait before I had a great QSO with M7PBT on 2M, so was happy to start with that.

When trying HF I could pull in the signals ok. I got a helpful text from G1TEX who was actively listening to me on the HF bands, but sadly I couldnt make a contact. On Tex’s advice, i packed up and moved location away from the Trees. Again the trolly really helped in moving.

Location #2, which was just around the corner, whilst missing a table did have a decent sized bench to sit on and get the equipment on. I could even get me flask out and have a much needed coffee ! Before long G1AJH (Andy) made contact, first on 2M then we coordinated across 17m and 15m, with a weak, but sucssful QSO on 15M. It was just the injection of encouragement I needed to keep going and I continued to persist with calling on 15M, by mid afternoon 15m and 17m had really opened up, I was easily receiving Canada, France and Scotland, trying to break into the pile-ups was really hard work thou, but I kept trying ! Thankfully IT9YAO was amazingly patient and got my callsign and report, I was really made up with making a DX contact on 10W and the loop !

After all the coffee it was time for ‘BoTA’ maybe 🙂 anyhow, I could only giggle at the suggestion made on the G4PRS net last week and felt compelled to take a picture 😀 (Actually it shows how well the facilities are maintained at the Park, its clean and tidy for sure)

Conclusion

I got back home and transferred my paper log to ‘Hamlog’ on my phone, so i could create the ADIF file for submission. Whilst I wont activate the park this time, i will at least show the attempt, where currently there are none.

I really learned allot from today and had huge amounts of fun doing it, yes there was some times of frustration, especially the mast and end-fed not going to plan, but that didn’t deter me from keep trying with what I had.

I think for future activations or any kind of testing, its best to go with the whip and one other antenna, I think taking the whip (attached to the bag) and 2 others was to much, as is, I only stuck with the loop in the end, and not even testing the whip, the time went very quickly !

The most important for me today was that I tried and got out with my radio and I can only get better and learn more by keep going out and trying, which is exactly what I will be doing !

Thanks again and 73 !

Parks on the Air (POTA) prep – Avon Heath Park ( G-0362 )

Posted on January 23, 2022 by webmaster@hamradio.knipmeyer.co.uk

I was originally planning my first Parks on the Air (POTA) this weekend, but circumstances changed and I’ve had to postpone the actual activation. Nethertheless I made good use of the time I did have by going to the park and checking it over. Sweety came along and we had a brilliant walk together.

Arriving at Avon Heath Park my Mazda Bongo will not fit into the regular car park due to height restrictions. There is a large parking area for HGV and PSV’s which other campervan/van type had parked in, so I went there. They should really raise the height of the barrier to 2m10cm like elsewhere in Bournemouth & Poole.

Carrying on from the visitors centre and amenities, there is a nice table/chair next to the reptile and bird lookout. If anything its a great place to sit and enjoy a rest, the pictorial ‘map’ is quite useful as well, but for a full map you can get one in the visitors centre with all the routes. I chose to do the “Viewpoint Trail” which is 3km long.

Sweety and I didn’t need to go far to find a lovely set of table/chairs, not only surrounded by lovely trees, but also a really nice passage to the next section of the park. The area around the benches has well spaced trees, allowing for either using the trees as a place to hook and end fed antenna up, or to put a pole up between them.

The route was easy to follow with well sign-posted arrows to follow, as well as nice posters of the inhabitants of the park. Sweety really enjoyed discovering the woods as well, making plenty of new friends on our walk around.

We had reached the furthest side of the planned walk, although not the park which extends further East from where the photos above where taken. Being the ‘Viewpoint Trail’ small diversions away from the trial give places to sit and enjoy the vistas across the heathland. Even on a cold Janurary day, it was a lovely view, and worth to come here just for relaxing and enjoying the scenery.

Continuing on the pathway I encountered the first real potential problem to operating, that being overhead powerlines. I am unsure if they would interfere with the radio signal by being in the proximity, but of course there is the very real risk to life should the mast fall onto the overhead cables, so that makes setting up in this part of the park a no-go area. We also encountered some very sedate English White Cows, I put sweaty back on his lead right away. Hes pretty good around other animals, but its best to play it safe, we walked by without problem and made it back to the car-park without issue.

In conclusion to the visit I now have a good idea of what I need, or more importantly what i don’t need, to bring with me and the quickest way to go there. Needless to say I’m really excited about coming out and doing PoTA for the first time !

I then came back home and as time allowed I could test the Sotabeams travel mast I had never setup before, even the ropes had to be cut to length for guying. This was quickly done in the space of my back garden and was really please to get the mast up so quickly and easily.

Testing Sotabeams Travelmast at QTH

Whilst today should of been about going out and operating, I have made the most out of the time I did have, which I think will make my actual activation a really good experience.

QRP Portable + 2M SSTV !

Posted on January 11, 2022 by webmaster@hamradio.knipmeyer.co.uk

Its been a busy time with radio activities, so much so I’ve barely had time to write up, so today I’m doing two for one !

QRP Portable

So having been inspired by numerous youtube videos to ‘get out the shack’ and being well equipped, I was determined to go out in my Mazda bongo with my QRP setup. The first thing I wanted to do was see if I could use my under-used Alexloop hampack in the Bongo, eliminating the need for any need to be outside of my Bongo.

I tested at home first in my drive way and getting the bongo roof up, IC705 and Alexloop in the Bongo worked well. Receiving signals was not a problem at all !

QRP Bongo QTH

So I asked my fellow G4PRS members a good high location to also do some UHF/VHF operation. I was not be disappointed when Whiteways Viewpoint was recommend by several members. Not only was it stunningly beautiful, and very windy, there was plenty of space to park and setup. I wasn’t alone in operation !

I setup my Bongo, IC705 and Alexloop. Whilst in the bongo I could get the SWR readings down low, but couldnt get my signal out but when putting the loop in the roof, there was some inductance from the small amount of metal in the roof and the SWR would go high.

QRP Operation Day 2 – Whiteways

I had a great time, and was glad that I had brought along my 2m/70cm Kenwood TH-D7, which I was able to put into the external antenna. I was quickly able to have a QSO via GB3IW repeater on 70cm, an impressive distance of 41 miles (approx)

I then tried out 2M and calling CQ, I was glad to be received by G3TOI in Christchurch who was monitoring during his HF / 80m activites. We have had QSO’s before, and its always good to catch up, but it was great to be so clear and a good report whilst mobile.

I really added to my portable QRP operation experience by this one trip out, I know now that for my antennas they will have to be outside the Bongo. As such I have got a pop-up tent to sit either myself or the antenna in the tent. I’m hoping to do more /M operation on the 17/18th of January – so keep a look out for me on the airwaves !

SSTV 2M

Whislt I still enjoy SSTV on HF (Mostly 20m and 80m) I really enjoy it on 2M also. Being able to use FM and upto 50W from my QTH with the Diamond x7000 antenna means I have the challenge of the terrain but the hope that I will also make contacts.

The SSTV calling frequency (144.500Mhz) is very quite in IO90BS, but I advertised the times I am almost always on via my QRZ page, i.e. 8-9AM on Sunday mornings. Whilst I didn’t get anyone during this specific period, I did leave my 9700 and MSSTV running, sure enough whilst walking in from the garden I heard a signal !

I sat down and had a fantastic 2M SSTV QSO with M0UVM, whose location is not geographically far, but still the other side of a large hill I have between me and Bournemouth Town Centre. I was really happy that someone had taken the time to setup MMSTV and put really good pictures in. We are planning more transmission on Sunday mornings with different SSTV modes and power. M0UVM is using an IC705 and only 10W, so doing really well !

Here are the excellent pictures we sent each other

Here is hoping that there is more SSTV on 2M !

Until next time, 73

QRP from the QTH

Posted on October 30, 2021 by webmaster@hamradio.knipmeyer.co.uk

So today is memorable for two things, one is my 28th Wedding Anniversary to XYL Monica. We are so blessed to have each other and I’m so thankful to have an amazing missus who I love so dearly.

Also today I made my first ever QRP contact from my QTH with 10W of power. I’ve had the ‘setup’ for a few weeks, and its been sat under my table (sadly) waiting for a time to go out. Today the weather has been fantastic in IO90, so I seized the opputnity to get out with the 705 in my front garden.

For those who are inclined, here is the setup I used today.

Transceiver :- Icom IC705
Antenna :- HFJ-350M & CGW-560 Counterpoise
Antenna Analyzer :- Rig Expert Zoom AA-55
Additionally :- M12 Copper Washer & BD7-Maple Antenna Bracket

I made myself comfortable with a long-used and reliable camping table and as being at home, a soft cushioned chair, which was invaluable for the tuning and waits for the QRP sessions.

I started off tuning the HFJ-350M (350M) for 40M. With the Rig Expert and instructions provided, this was suprisngly easy to get the antenna tuned for the SSB Telephony section of 40m. I started with the measurements from the instructions, and then adjusted the antenna until the SWR was at a good reading.

However with the contest on this weekend 40m was simply full of contesters. I don’t mind on my usual home-rig to take part in contesters and give the 001 serial to give a signal report, but being QRP and for 5-10 with an Italian call sign who was very clear to me, I was unable to complete the contact with my QRP setup.

For interest, I then went onto 20m (14mHz) and found tuning the antenna was straight forward. To start with it was quite close to having a SWR reading of 5-to-6, whilst not good enough, it was better than the ‘infinite’ value, so some fettling with the antenna in slowly sliding and taking a measurement soon produced the whole of the 20m band with good SWR reading for transmission

Again, 20M was full of contesters and I was unable to break the pile ups with my 5W of power. At this time I headed into the ‘shack’ and grabbed my LiFO battery, allow the full 10W of power to be used. I also research non-contest bands and QRP frequency. I found that 17M (18Mhz) was a non-contest band. I was able to use the same method to get a good SWR reading across the 17m band – the antenna was at least matching very well and using a repeatable process I could use in the field.

With some time and patient listening, I heard a call on the QRP frequency on 17M of 18.130, and with of effort with both myself and the operator from Finland listening was able to make my first QRP contact. It was incredibly satisfying with such a low power and compromise setup to make a contact on HF – my report was 5/3 with a very weak signal, understably with 10W and in an urban environment – needless today I was ecstatic to make a contact.

QRP contact video

Whilst I was unable to capture the video (the run time would of been over an hour !) I do capture the unbridled joy of a QRP contact on a portable setup. Hopefully I will be able to make more trips to less RF noisy environments as I thoroughly enjoy QRP operation as it gives a fantastic sense of satisfaction in making contacts with such small amounts of power.
