Sadly Peter Best - G8BLS - passed away today. It is due to Peter asking me to help out on a JOTA event that I am now enjoying Amatuer Radio again.

The results for the RSGB 144Mhz CW Marconi competition are now out! I came 13th!

November 8th 2015

Took part in the RSGB 144Mhz CW Marconi competition. Not to win, just to give away some points. Log below. Please with the G3MEH contact, that's a long way for me on 10 watts!

Today FDARS were at Martlesham Heath Aviation Society and Control Tower Museum putting on a special event station for thier fun day.

August 2nd, 2015

Today the Bawdsey Radar Station was celebrating the 75th anniversary of the battle of britain. the FDARS were there with a demonstration station. The bands were quite flat but we did manage some contacts.

Stations worked in CW include F5JAA, G0CWM, G0NMD/P, HB9LAG, F6AGQ, G0DZB/P, DL4FCH/P.

May 21st, 2015

Working /P again while the boy went sailing, again at Woolverstone – see the map below and again using the end-fed 20m half wave and the G0KYA tuner. Cold wan't a problem this time - it was flies! Managed 3 contacts:

  • LZ2OQ
  • OH6KD - 1102 Miles
  • E74SL - 919 Miles

Pictures of the /P station.

May 10th, 2015

Today was "Mills On The Air Day" and FDARS activated Woodbridge Tide Mill as GB2WTM. Peter, G8BLS, setup a doublet and we mainly worked 40M. I worked CW and the first few CQ calls were seen by:

I didn't work that many stations as all the QSOs turned out to be quite lengthy. The CW log is shown below. In the afternoon Steve, M1ACB, came along and logged some 80 or so SSB contacts!

Below we have Peter, G8BLS, and Steve, M1ACB.

I also managed a 2M CW QSO with Chris, G3XVL, in Ipswich some 8 miles away using my FT-817ND.

April 24th, 2015

I fired up the Pixie again tonight and sent out a quick CQ. To my astonishment Michael - G0POT - returned my call! i was a little harsh with the signal report but it is hard work on the pixie!

To reduce the amount of noise I was using G4BJM's two-component filter - a 47mH inductor inline with a 1uF capacitor. See here for more details. I also had a small audio amplifier to make up the difference after filtering. Another filter to try would be the G3VTT filter described here.

Also see this tweet here.

April 23rd, 2015

While the boy went sailing I took the opportunity to setup a portable station on the foreshore near Woolverstone – see the map below. I used an end-fed 20m half wave and the G0KYA tuner. Managed three contacts before the sun went down and it got too cold!

  • RA6BX - 1771 Miles
  • HA2RAU - 852 Miles
  • 9A0QRP - 800 Miles

For 2.5 Watts the coverage I got was quite good.

Pictures of the /P station.

April 14th, 2015

My first portable 80m operation in the back garden! The antenna is an inverted L (10m up and 9.8m out) with a 9:1 un-un to reduce the impedance to something that the ATU can handle. For more details on this antenna see Stealth Antenna by Steve Nichols, G0KYA, Page 110.

I used it to take part in the FDARS 80m CW Net and worked Chris G3XVL and Ken G4RHR.

The Russian ARISS team have been sending down more Slow Scan TV (SSTV) pictures on 145.800 MHz FM from the International Space Station (ISS). The pictures below are the results obtained. Not very good this time!

More information about AMSAT can be found here.

April 9th, 2015

Operating /P from Congleton in Cheshire. Worked Erhard OE7EHH (20m), Chris G3XVL (40m), and Derrick M0BDD (40m).

March 26th, 2015

This was the oddest that QSO I've had so far! OZ90IARU was calling CQ on 40m and I replied in the normal way. All I got back was G0PJO 599 and that was it. I though a special event station may have given more. There was no pile up waiting! Extact from ClubLog given below.

March 21st, 2015

With the help of an audio CW filter from RadCom (April 2015) I actually managed to hold a QSO with Eddie G3WNQ, some 60 or so miles away! He gave me an RST of 569! The filter was constructed on breadboard and was a bit of a mess!

February 26th, 2015

Today GB8ORE (Original Radar Experiment) located in Daventry communicated with GB8ODX (Original Daventry eXperiment) in Bawdsey to celebrate the 80th annivesary of the original Daventry experiment by Robert Watson-Watt to prove that radar was possible. The Bawdsey station was operated by Peter G8BLS, Paul G4YQC, John M0MGN, and Graham G4FSG. Eddie Izzard took part in the celebration as he played Robert Watson-Watt in the BBC drama "Castles In The Sky". A short BBC news report of the event can be found here.

You can listen to the converstaion between Eddie Izzard and Graham G4FSG below.

There is an article about the event in RadCom, May 2015, Volume 91, Number 5, pages 68-69. The article title is "Commemorating British Radar The 80th anniversary of radar's invention."

February 25th, 2015

The Russian ARISS team have been sending down more Slow Scan TV (SSTV) pictures on 145.800 MHz FM from the International Space Station (ISS). The pictures below are the results obtained. There should be 12 but I only managed to get 10!

How much fun can you have for £4.82? I found this on an auction site and just had to have one!

It will be interesting to see how easy it is to build and how well it works! To be honest, for the price you can't go wrong! An online video of the TX/RX can be seen here.

February 12th, 2015

It seems that the "noise" that I heard on 7.090 MHz on January 21st was Russian Over the Horizon Radar. See here for more details http://www.iarums-r1.org/iarums/news2015/news1501.pdf.

February 7th, 2015

I've never had a QSL card sent to me directly in the post before! Many thanks José - CS7AFI.

January 21st/February 1st/February 2nd, 2015

All weekend the Russian ARISS team have been experimenting with the amateur radio Slow Scan TV (SSTV) transmissions on 145.800 MHz FM from the International Space Station (ISS). The pictures below were harvested from this experiment using an Icom IC-E208, a simple 2m / 70cm vertical dipole, and a copy of MMSSTV running on a PC.

The quality of the pictures is not brilliant but considering where they are being sent from and the fact that I have no directional antenna to point at the ISS I don’t consider them to be bad.

To track the ISS I used Ham-Radio-Delux and that provided me with the display below. The predictions on the left hand side are very handy.

January 21st, 2015

I turned the transceiver on this evening with the intent of working CW on 40m only to find a massive pulsating signal spread across the entire band. It seemed to be centred on 7.090 MHz at which point the S-Meter was hitting the end stop. My initial though was "Who has turned what on?" there was nothing new in the house so it had to be from elsewhere. I picked up the FT-817ND, attached the 2 M antenna, tuned to 7.090 MHz and sure enough there was the noise. Walking around the house and garden showed no variation in the signal level. I wandered down the road and still no change. When I got back home I called my friend Chris G3XVL who could hear the signal too and he is seven or so miles away which I was pleased to hear as that meant it was nothing in my house or the immediate vicinity. At this point the signal moved to 6.855 Mhz and could be heard on various SDR’s around Europe!

I have no idea where it came from?
