I recently built an MDT transceiver kit. This is an extreme low power 40 mtr radio to communicate with Sigle SideBand radios. It is very small & light weight too. The receiver only draws 50 Ma on receive and the transmitter consume 250 Ma with 2 watts RF out. It's fairly easy to build and adjust. I'd say beginner to intermediate skill level. But it doesn't transmit SSB.... MDT stands for Minimalist Double sideband Transceiver. Yes, DSB has some limitations but also makes for an easy to build and inexpensive radio for talking to SSB radios. It transmits both upper sideband and lower sideband at the same time. Combined with a well designed Direct Conversion receiver makes a great low cost / low power combination for backpacking or emergency use or whatever. An NVIS antenna is ideal for this little rig. First, the kit is complete with case and knobs and everything. Leon Williams, VK2DOB is the designer and sells the kit out of Australia. I was surprised that even with shipping the total was just over $80 US. Second, I built the kit in less than a day. Spent a couple hours the next day adjusting it. and had it on the air that afternoon. Third, the real test was using it in the field on battery power not in the shack with the base antenna and power supply. I strung up a light weight 40mtr dipole I made a couple years ago... Fed with 20' of RG-58 coax with no balun at the feed point. The antenna was only 10' off the ground. I made contacts out to 400 miles... The first to answer my CQ was N3APA out of NoCal. Also made contacts into Montana and Nevada. Even QRP to QRP contacts. One guy was using an Elecraft KX-3 bicycle mobile! I check into the west coast Noon Time Net about every other day wen I think about it. For field use I power the MDT with 3 old cell phone batteries in series. They last a couple days before I have to recharge. I also made a little antenna tuner to compensate for the detuning of the antenna when low to the ground and different ground conductivity. It has a built in SWR bridge with LED indicator. I think the MDT is a terrific kit radio for the beginner or seasoned ham. Not hard on the budget, easy to build and good daytime NVIS performance. Something fun to take camping or hiking to give your emergency comm experience a little exercise. Here are some photos of my set up.
