Good fun for QRP

Military SEM-35, Mobile HF/VHF Transceiver

SEM-35 are fairly easy (and cheap) to come by in my neighborhood. I got mine from an online surplus store for only 35 euros. But what fun you get for your money!
I bought a tele-mic and 2.5m whip antenna with the set. Also, I took out the battery holder and replaced it with a 230V AC power supply. Now I can just plug it in and switch it on.
Built quality is superb. It should be watertight even, although the rubber seals are showing their age so I'm not leaving it out in the rain.
