PFR-3A Field Tests

Using VMEPT and a Hellschreiber WAV file I set up a beacon to transmit every two minutes with my Yeasu FT-817. Then using a half-wave piece of wire (end-fed) and a counter poise wire, I used the PFR-3A as a receiver with the internal antenna tuner to test NVIS propagation around my QTH in a 10 mile radius.

I was able to successfully decode Hellschreiber in the field using my iPhone app HERE. I also connected a small amplified speaker and recorded the audio and used that with FLDIGI to produce the screen shot above. I had hoped to use the PFR-3A to decode FSQCall but the software is centered on 1000 hz verses the 600 hz center of the PFR-3A CW crystal filter.
