In 2019 I organised a trip to a remote farm in Devon for a mini DX-pedition, a sort of radio holiday for a few good friends and club members to play radio non stop for 5 days with 10 acres of field to erect antennas and a non existent HF noise floor. We took three Kenwood TS-590SG sets with us and I was amazed with their performance in a multi radio environment. One was running QRO via an Elecraft KPA500 amplifier and there was never any problems with interference between the operating stations. At one point, we were working CW on 20m @ 100w using a ZS6BKW and working SSB on 20m @ 100w using a DX Commander with around 15m separation of the antennas with no issues. The only slight interference issue we had was if another operator was using an exact second harmonic but even then, most stations were still workable.Continue reading “IC-7300 In Multi Radio Environment?”
I’ve been running my TM-D710 in the car for a while using a Garmin GPSMap 60CSX which works well but does add clutter to the dashboard and is just another device to remove when leaving the car in a public place. I could upgrade to the newer TM-D710G but I can’t justify the £550 price tag just to get a built in gps so I have decided to add a gps unit to my existing unit.

This is a simple modification that takes around 5 minutes but makes a big improvement to the already great TM-V71. The fan on this radio is very loud and runs at full speed from the moment you press the PTT then stays on for a few minutes after you release the PTT. This isn’t a problem in a mobile setting where there is usually more background noise but it is very loud when using the TM-V71 in a quiet home shack.

The Kenwood TM-V71 is a great dual band mobile set that is at home in the car or the home shack. It’s packed full of great features and has a good power output of 50W on both VHF and UHF. I’ve owned Icom, Yaesu and Kenwood dual banders and I just love the TM-V71 so it’s no surprise that I snapped up an ebay bargain for a faulty one (dated 2009) when I saw it.
