Ham Radio

I was checking propagation when I heard The ARRL Head Quarters coming in on 20m. The best bit was when he herd me calling on 20 watts. Check out the video and see for yourself. 73!

Latest DX - Testing The G17B Amplifier Across The bands

The last two weeks have been interesting on the bands especially with the new Russian G17B x2 amplifier in line and working well. I have made the most of the propagation which has been up and down but worth the effort, as I put out some nice signals into North and South America as well as the Caribbean. I am really pleased with the G17B amp and have mastered the tuning and loading with no issues or difficulties. I feel much more comfortable with the reliability and duty cycle of the Russian made Ceramic tubes compared to a transistor amp which seem less forgiving of any minor operator errors. 
I have backed the mic settings off slightly for my Heil GM5 studio microphone and have been putting out 20 -30 watts from the FT-1000MP Mark-V Field transceiver into the amplifier and getting 350 - 400 watts out. The reports have been very encouraging, all that is left to say is CQ World Wide SSB Contest 2018, here I come!!!

In the meantime have a look at the guys and girls I have had the pleasure to make QSO with over the past two weeks. Best 73 hope to work you soon! M0YKS - Simon

Home brew PTT x 2

The new amplifier is set up to operate via a separate PTT  which was a foot pedal. I found this easy enough but had a better idea to try out with a couple of TIG welding torch rubber insulated switches that I had lying around. I began by making a stainless steel cradle to house two switches which would be one for the radio and one for the amp. I then tacked the whole assembly to my previously home made microphone tower.
 I used a piece of stainless steel as a gate type switch system which makes contact with both switches to activate transmit on my transceiver and amplifier simultaneously.
whilst testing out the new double PTT set up I worked Bruce WD4NGB just as the 20m band was grey lining and fading.  Feeling very pleased with myself after a bit of ham radio making! Best 73!

DX Hound
It looks like Finn the lurcher is loving my ham radio activity. Earlier I had my new amp ticking over as I worked Bob VP8LP down on the Falklands.
Catch you soon with a closer look at the Russian made power amplifier that seems to be working superb.  73
