A Message from Walter KA4KXX -- On Bias Setting, the Joys of Al Fresco Rigs, Lawn--Sign Radio Base
Dear Dean KK4DAS:
Dear Dean KK4DAS:
Ed W4YWA is far too modest -- he has built a very FB homewbrew transmitter. Congratulations Ed. I think your original plan to use a Web SDR receiver will work, if you and the other station are just willing to pause for an additional second or two to let the internet catch up with the real world. Also, you might find some Web SDRs that have less latency than other. You could used a little SW receiver or a simple buzzer for your sidetone ( I think sidetone is your most pressing latency concern.) My suggestion is to try to get a few contacts using the Web SDR (perhaps via schedule -- try the DX Summit or the SKCC web page to set some up). Then build yourself a simple Direct Conversion receiver to use with this rig. You don't have to try to build a VFO at 14 MHz (that can be difficult) -- you could build one at 7 MHz (use the circuit from our High School receiver project) and pair it up with a "Subharmonic Mixer" so that you can tune the 20 meter band. Please keep us posted on your progress.

Home-Brew Fun and Failures
I kind of arrived at Dick Benson's QRZ.com page by accident, but what a happy accident it was. There is a lot of homebrew goodness on Dicks page, both SDR and HDR.
