Just before I got back on the air on 2011 I heard the term SDR. Not knowing what this was about I read up articles and adverts and learnt a bit about what it was about. Since back in 1990 I had intergrated an IBM PS2 PC with my PK232 and my Kenwood TS850s, I thought SDR was the way I wanted to go. So after a few months of using the TS850s I bought a Flex 3000 SDR. That is a very good transceiver and had very good fun to use. I then started seeing the next generation of SDRs come out.
This is a view from the top of my antenna mast.
I have recently upgraded my Anan 100D to the new Anan8000DLE, This is a new SDR Transceiver from Anan that has 200w output power using 50v PA that is built in. This is built following the work of the OpenHPSDR project which has some very clever people working on the development of SDR in their spare time. So this radio is cutting edge and is regularly updated with firmware and software GUI. Since becoming an owner of one the improvements have been outstanding, a couple of them being able to use the second Rx in the box for Diversity and by far the most important upgrade was PureSignal.
Elecraft KPA500 HPA
Back in 1987-1994 when I was first licensed owning an amplifier was rare.
Now every man and his dog has one. I thought of going the Valve route but it needs tuning on every band and since a lot of may operating is remote retuning would be an issue. So after reading reviews I went for the Elecraft KPA500 kit and built the amp from the kit. Im very glad I built it as it was a very rewarding process.
Elecraft KAT500 ATU
I have 3 antennas that I can use andtwo of them require tuning, so the Elecraft KAT500 fitted the bill nicely with 3 tx antenna ports and built in switcher.
LP-100A Digital Vector RF Wattmeter
Measuring your tx power and SWR is critical. I have used Cross needle meters before but again, due to the station being used remotely, I needed a way to get the power and SWR readings. I saw this unit reveiew in QST and though it was just what I needed. I got the unit with a single power sampling probe but have updated it to two now.
This is a key peice of software I use in the station. This manages to bring together all the information from the Anan, KPA500, KAT500, LP-100A and Ham Radio Deluxe so that all the devices know what frequency I am on. Again this software is written by some very clever people in their spare time so it is quite impressive. This software helps me to run the station remotely and thanks to its Auto-Power feature it enables me to use the Anan100D as if it was a 400w transceiver. Highly recommended if you are using SDRs.
I have recently got one of these radios for the car. I am finding it is a very good mobile radio. It is very easy to use once you know the Icom menus. The Near Repeater feature is the best thing I have found so far. Also I have found I can use it for working FM satellites.
I decided to get an IC7100 for the home shack as I wanted something that could do VHF/UHF. Also since it did DSTAR it was useful for it to work with my Raspberry Pi DVAP dongle. I have yet to try out HF DSTAR yet.
Since starting to get to grips with CW I have been wanting to get to operate portable. The idea of operating low power with a temporary antenna is one that had driven me to really push to get my CW speed back up. So I went a bit crazy and bought and LNR LD11,
this is a great little rig but I found the clicks when I transmitted CW annoying and off putting, on SSB and low power data modes its a great little rig. From all the Youtube videos I have seen CW seems to be the mode for portable operating, so I tried the Elecraft Kx2 and I had to have one. The Kx2 is a very impressive little rig worth every penny. The receiver is very impressive and tx is very clean.
Currently the antennas at G0MGM are:
Ultrabeam UB20Mx Dynamic Antenna (20m-6m)
Butternut HF9V Vertical, ground mounted with approx 15 radials.
Homebrew 40m Delta Loop with a MFJ 994BRT remote ATU. Apex is at about 30ft and the bottom at about 10ft. Tunes from 60m through to 10m.
2m SSB – 7 Element PowAbeam from The DX Shop
5 ele Log periodic from Elk for 2m and 70cm for portable work and satellite comms.
2m/70cm Diamond X30N dual band vertical
For the second Rx in the Anan I have a Wellbrook ALA1530+ Magnetic Rx loop, this is a great addition for rception from about 20m-MF.
