Hello, and thanks for looking me up on qrz.com

My name is Stewart and I live in Nairn in the Highlands of Scotland, approx. 13 miles East of Inverness.

Please note, my postal address is not complete for security reasons. Please do not try to QSL direct. eQSL only

My radio equipment consists of the following:-

Transceivers Base:-Flexradio Flex- 5000. I owned a Flex-1500 for a while to get my feet wet with SDR and was well impressed, so once I became familiar with operating it with PSDR I decided to bite the bullet and buy a Flex-5000 (used, at a very good price)  Flex-5000 now sold. It has gone to a good home.

 

 

I recently sold my Flex 6300 and aquired a Flexradio FLEX-6500.  I managed to sell a couple more of my seldom-used radios, and used the proceeds to buy the Flex-6500. 

 

 

 

                           4 Simultaneous receivers running on the Flex-6500

 

 

     I also have a Funcube Dongle Pro +,   

 

 

 

 

 

 

and an SDRplay

Kenwood TS-B2000  Used mostly on 2 Metres and 70CM.

Kenwood TS-830. Sold. I know I'm going to regret this!

Amps:- Ameritron AL-811 for HF; Acom 1000 for HF & 6 Metres; W1SL & ME-1500V for 2 Metres; HA1YA ME300 4M amp.

Antennas:- 2X 9 ELE Vaargada at 65 ft for 2 Metres; Cobwebb at 35ft for 20M to 10M; Carolina Windom 80, shallow vee, 55ft apex, Double-Bazooka at 15ft for 60M NVIS; Dual band 4 ELE Cubex Quad for 4M & 6M; various verticals for FM on 6M, 4M, 2M, & 70cm.

DSTAR

Icom 7100

I bought an Icom IC-7100 some time ago, mostly for the 4 Metre multi-mode capability, but then thought as It's also a DSTAR radio I'll see what that's all about. Unfortunately at the time there were no DSTAR repeaters, nodes, or hotspots in the area, so after trying a few DV simplex contacts, and discovering that it beat FM (even FMN) simplex for sensitivity, I decided to apply for an NOV to operate a DSTAR hotspot. In less than 48 Hrs I had the NOV, and a GMSK modem board. With the modem linked to a Raspberry Pi running the G4KLX software MB6TU came on-air.

MB6TU mobile coverage includes the A96 to Inverness, parts of Inverness, a chunk of the Black Isle, the A96 East to Elgin (with a few black spots), and the A9 South almost to Aveimore (with several black spots). Not bad for 2 Watts ERP. MB6TU is usually linked to Scottish D-Star Reflector XRF600     http://www.gb7de.co.uk/xrf600.html    in the morning, and DCS005B the rest of the day.


MB6TU is on 144.8125 MHz

I wasn't happy with the two SO239 connectors on the rear of the 7100, so I changed them to N-types. This was very easy, and didn't involve any soldering. After removing the screws holding the sockets in-place, just pull them off. The centre pins locate in to spring-loaded clips on the main PCB. Make sure the N-types have long enough pins to reach the clips. If you remove the top cover of the rig you can check that they have located correctly.



 

     I also recently bought an Icom IC-92D HT so that I can use DSTAR from anywhere in the house and also when I'm out for a walk with the Dog, or bicycle mobile. It came with the GPS mic.

 

 

 

 

 

 

 

 

 

 

Some time ago I acquired 2X 12 ELE 144 MHz LFAs to replace the Vaargadas, and also 4X 16 ELE 70cm LFAs, from Justin G0KSC. I drove down to Canvey Island to collect the antennas so that he wouldn't have to cut the booms in to short lengths for posting. I was able to see Justin and his Dad making and mounting the last four elements for each 70cm LFA. I was astounded at the attention to detail employed in the construction. No cheap & nasty mounting hardware anywhere; only the best marine grade stainless steel fittings, right down to the locking washers. Justin uses a digital caliper to get the element lengths spot-on, and I mean spot-on. Is this man a perfectionist? You bet he is.

I was even taken out for dinner with Justin, his lovely wife, and youngest son. Justin and I finished-off the evening drinking fine wine and discussing antennas. Customer service? I have never experienced anything like it.

If you are thinking about buying any new antennas do yourself a favour & contact Justin http://www.innovantennas.com/ to discuss your requirements. He has another web site with details of his antenna designs and construction details for DIY at http://www.g0ksc.co.uk/

 

I've also started constructing an OZ2M 4 Metre transverter & PA to replace my ageing Microwave Modules unit for base use. 

 

EA8/GM0GTU

In 2013 I bought a holiday home in Golf del Sur on the South coast of Tenerife, where my YL and I plan to spend the Winter months. I took my FT-857D with me last Winter along with an SGC-237 Autocoupler, and a Sidekick screwdriver antenna. Unfortunately I wasn't able to rig any antennas at the time, so only operated with an HT. This Winter I'll definitely have antennas up, i.e. a 10 Metre long roachpole vertical with 2 radials fed by the autocoupler or the Sidekick, and a dual-band white stick for 2 Metres and 70cm. I'll probably take the IC-7100 with me as well.

Update February 2015:-     I'm now back in the UK after a lovely Winter in Tenerife. Radio-wise it was a disappointment. I couldn't access the DSTAR repeater on Gran Canaria; in fact I couldn't even hear it. I installed a Diamond X-50 dual-band 2M/70cm white stick antenna on the roof. I did have a couple of 2M FM simplex QSOs with a couple of visitors to the island, and through one of the analogue repeaters.

For HF and 6 Metres I managed to rig a short doublet with the SG-237 Autocoupler at the feed point, but the results were abysmal. The doublet isn't long enough, and it's too low. I have to be a bit stealthy as the house is on a residential complex, and the management committee are quite strict about what one can erect.

Winter 2015/2016     This winter I tried a 6 Metre long vertical with 2X 7 Metre long horizontal radials 180 Deg. apart, and fed with the SG-237. Again the results were bad; S7 to S9 of noise on every HF band except 17 Metres which was actually very quiet. 6 Metres was also quite quiet, but I heard no activity whatsoever. There are lots of strings of solar-powered LED lights festooned amongst the branches of Palm trees, and along walls, all over the complex and the one next to us. I suspect that each of these is a noise generator. It looks like HF activity from the house is hopeless.

 

 

F/GM0GTU/MM

I'm no longer working on board the Helene, so the equipment has been removed.

I work for Oceaneering International Inc. as an ROV Superintendent on the vessel Bourbon Helene. We are engaged in sub sea construction and inspection work at 1700 Metres water depth off the coast of Angola, loc. JI52.

 

While on board I operate as F/GM0GTU/MM, mainly PSK and more recently Olivia also. My equipment is set- up in my cabin and is as follows:-

Transceiver- FT-857D; PC- Dell Inspiron 6400; CW key- Palm Paddle Mini; SignaLink USB digital interface; the antenna is a 8 Metre long marine whip with SG-230 autocoupler on the roof of the Bridge.
