First POTA of 2024 – G-0112 New Forest (again)

Posted on by

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.

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 today
radial spread
much 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 great
could I try a choke here
Will 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…

Until the next time, 73s !
