M2 and I0JXX Antennas for the 144 MHz Band

Received the 8JXX2 antenna on Friday and built it up on Sunday. I also have a new M2-2M9SSB antenna recently assembled so here are a few comparison notes on mechanical and build quality. The specified electrical performance is very similar. Both antennas make use of stainless steel fasteners.

Brian's 27-element QLY (must look that up!) at about 5m agl.

LRS member Brian Howie GM4DIJ had a try at the UK Microwave 23cm Contest on Sunday 8th March 2020 for a couple of hours. He had meant to be out for the 144/432 contest on the Saturday, but the wx was bad.

The location was IO74mu, about 8km south of Stranraer, about 90m asl with a good take-off North round to South, where he was partly obscured by the Mull of Galloway.

 

Following John Cooke's talk on amateur radio applications for the Raspberry Pi microcomputer at the March 8th LRS meeting John now reports that he has successfully received the FUNCube-1 satellite using a Raspberry Pi 3.

The Lothians Radio Society again operated in JOTA - Jamboree On The Air - from the Bonaly Scout Camp Site near Colinton on Saturday 15th October 2016. Using the special-event callsign GB0BSS, the operators were John Cooke GM8OTI and Malcolm Hamilton GM3TAL. This year the operating position was in the Training Room, which was a bit warmer than the open barn used in previous years! The room was shared with JOTI - Jamboree On The Internet.

Brian Flynn GM8BJF and Briain Wilson GM8PKL made an expedition on Saturday 19th March 2016 to Telegraph Hill near Coldingham, Scottish Borders to check on reception there of the 3cm beacon GM8FFX/B which Brian had built and installed in May 2015 at the QTH of Graham Knight GM8FFX near Aberdeen. (Click for report). There is a completely clear 126km sea-path from Aberdeen and Brian was delighted but not surprised to find the beacon pounding in strongly at Telegraph Hill. He was also glad to find it was still bang on frequency!

LRS club members John Cooke GM8OTI and Malcolm GM3TAL operated radio station GB0BSS for the 57th Jamboree on the Air on behalf of local Scout groups at the Bonaly Scout Camp Site on Saturday 17th October 2015.

Background

I met Graham Knight GM8FFX at a local rally last summer. He told me he was back on 2m and had been working Chris Tran GM3WOJ. He mentioned that Chris had told him about the 10 GHz beacon I had built to put on at his QTH near Tain and in passing Graham reminded me that there was a proposal back in the mid/late 1970s to put a 10GHz beacon on from his house south of Aberdeen. This never came to fruition for reasons that are now lost in the mists of time and he asked if I had thought of putting it at his QTH. I said that I was willing to put together another personal beacon for his place. Graham has an outstanding VHF/Microwave QTH with a clear view over the North Sea and consequently a sea path to PA0 and East Anglia. In November 2014 I visited Graham and the subject arose again and I agreed to go ahead building the hardware. We also decided that a suitable spot to mount it was on a pole supporting his HF antennas. Over Christmas and New Year I built up the hardware and tested it.

Scouts from the 114th (Fairmilehead) Troop with leader Paul Fullerton.

John Cooke GM8OTI and Alan Masson GM3PSP operated GB0BSS in JOTA - Jamboree On The Air - from Bonaly Scout Camp for the third year running. Scouts from the 103rd Braid (Greenbank) and 114th Braid (Fairmilehead) troops participated. The objective was to encourage the Scouts to operate, speaking into the microphone, giving their own information - name, age, troop - and asking questions of the Scouts at the stations they contacted.  

 

LRS member Brian Flynn GM8BJF has installed a new 3cm microwave beacon at the QTH near Invergordon in grid square IO77ws of well-known DXer Chris Tran GM3WOJ (and using his callsign). This is Brian with the equipment on the side of Chris's lowered mast before it was raised to give a beacon height of 11m, beaming at 165 degrees. This allows scatter propagation over the top of the Cairngorm mountains and reception in Edinburgh at Brian's QTH at a distance of 215km. It has also been heard in Bishop Auckland, Co. Durham at an amazing distance of 376km. The beacon sends GM3WOJ IO77ws in both CW and JT4G digital.
