Hello everyone, I have joined Amsat and this is my first post. I am looking for home brew transverters. I have a SDR 1k withthe internal 144 DEMI that gives me 28 IF out. There is no way I can afford to buy transverters from DEMI or Elecraft. I am on very limited funds (SS). I can afford to make PCB's and buy parts or have PCB's made. I looked at farcircuits and googled. I founf plenty of stuff for 5 GHz and up. I would like to build a 70cm first and then a 144 to use my SDR in my new adventure into the world of sat operation. If anybody has gerber files or has built one (especially 70cm), I could use the help. 73's
