Just saw the following kit for 17.5 GBP, exciter that can transit anywhere from 500Hz to 40+MHz in QRSS, WSPR, DFCW, Hell and others. Has provisions for GPS locking: http://www.hanssummers.com/ultima
Yup. I'm running one right now in WSPR mode on 457.730 kHz. Very neat kit, but definitely QRP. I've tweaked mine up to about 1W rf out. A friend of mine, G8AJM, runs one on 20m. He's got to VK once o
Hi, Alex. I connected the U2 PA stage to a 12volt supply, and the BS170s blew up! I now have a slightly larger FET, a BSP126, in the PA stage. The BSP126 is a surface-mounted device, and is soldered
