callsign is DK7IH and my radio amateur station consists only of
homemade gear. I prefer the 20 meter band using phone operation.
My favourite rigs are a handheld transceiver for QRP SSB and a pocket-size 4-Watt SSB Transceiver which you can see underneath. The basic data of this neat little TRX: QRP Transceiver for SSB operation, DDS, 4 watts out, 20 Meter (14 MHz) only. 2 mixers, 1 filter, 1 if, AGC. The microphone is a CB type dynamic one. Here's the schematic, if you're interested in technical stuff.
