Modifications to the MDT 7 MHz QRP transceiver (and a 2 x MDT contact) https://stream.echo6.co/videos/watch/355b7615-648f-48e4-8eba-87affca050b4 Modifications for the OzQRP MDT 40m DSB transceiver kit. They improve frequency range, tuning ease and convert a dynamic microphone into a speaker-microphone. There is also a demonstration of what QRP DSB from another MDT sounds like on a direct conversion receiver. It can be quite copiable but tuning in is much harder than for SSB.
