SARL FD Sep 2015 – Golden Gate National Park

I set up a field station on the veranda of our highlands retreat log cabin, situated in the magnificent Golden Gate National Park some 4 hours drive from my home . The views to the east and north were awesome.

I used a telescopic fibre glass mast and erected a link dipole for 15, 20 and 40m. I used my trusty Elecraft K2 transceiver and Begali HST paddle.

I started calling CQ on 40m CW, after 20 minutes I gave up in disgust, I did not have a single reply. IMHO CW is in danger of becoming obsolete in South Africa.

I tried my luck on 20 and 15m, but the propagation was simply too poor to enable any QSOs with my QRP setup.
I had no option, but to revert to using the ‘muggle’ mode. I really don’t enjoy using SSB…..

I was looking really looking forward to the field day event and I had high hopes that the event would be well supported, but alas that was not to be.

All this effort to end up with only 22 QSOs in the log :-(

AFRICA-DX 2015 contest results

IMHO the inaugural AFRICA-DX contest was a success. A total of 123 logs were received.

We had some issues with overlap with the RSGB Commonwealth contest and a few minor issues with the log checking process. Igor UU0JC the author of the “LogChecker” has been very accommodating with our requests for software features.

Next year we hope to gain momentum, with a bit of luck the AFRICA-DX (all mode) contest will become popular for the contesters and the DX hunters alike.

Thanks to all those that participated, the next one will be bigger and better.

The next contest will be held on Friday 11 March 2016 starting at 1800 utc and ending on Saturday 12 March 2016 at 1759 utc

2015 SARL Winter QRP contest

As you all know I am a huge fan of QRP, but after reading the feedback below from Roger ZS6RJ (the guy with the rather loud headset) I could not resist sharing his feedback "Ode to a QRP contest".

Conditions on the higher HF bands were rather poor and working QRP DX from the southern tip of Africa was not easy to say the least.

I did not work a single DX station, I sure hope others fared better.

Ode to a QRP contest:

“Come help with QRP”
“It’ll be a hoot, you’ll see”

I raised the hex beam with great glee
Ignoring the fiberglass stuck in me

Calling ad-nausea for more than an hour
Left me disillusioned and rather sour

So as the QRP leader broke down the camp
I whacked him over the head, with my linear amp.

Building the Ultimate-3S WSPR kit

I set aside a few hours to build the U3S from QRP kits.

The build went fairly well, the instructions are fairly clear. When I first applied power it was obvious that something was wrong. What I saw on the display was not what I expected to see.

I did some fault finding and came to the conclusion the 20 MHz clock was not functioning. I carefully removed the crystal and replaced it with a temporary 10 MHz crystal.

I then powered the U3S up and I was very pleased to see “Diagnostic mode” displayed on the display.

Tomorrow, I will try and find a suitable replacement crystal. Then hopefully I can set it up to WSPR to the WWW on 10m.

What a relief……

This is a problem !!
