Last year I already build a 4 meter transverter. I only had to connect it to an HF radio. I decided to make a switch box so I can choose between the standard FTV1000 who is behind the FT1000MP and the 4 meter transverter. This is working fine Now. Jan PA0VAJ build me a small PA so I have now 2 watt. No I am not going to run qrp. A bigger amp already is build but I need more drive power.
