Hello Topbanders, today I forgot to hook the keying line to my KD9SV preamp. I destroyed the OMRON G6A relay, witch bypasses the preamp. It is available in DL. The problem is the 3SK88 transistor. I heard KD9SV is now using BF-981 with a small modification (cut one trace and add one resistor) Anyone knows the details? TNX in advance! Tom, DJ5RE
