I found a complete set of PC boards for the ST-6 demodulator. This is a complete set for both shifts and also the AK-1 AFSK modulator. Is there any interest in them? If so, please contact me directly with your offer. Thanks. 73, Ken, W8EK Ken Simpson E-mail to W8EK at FLHam.net or W8EK at arrl.net Voice Phone (352) 732-8400
