MFJ-434 Voice Keyer
(Owned by WB9Z)

26 Feb 2009

Connected keyer to FT-1000MP(3) at Station # 3 and the VFO began scanning down in frequency. Pulling the plug from the transceiver's mic jack was all that would stop it. Unsoldered wires in this connector from Pin 1 (White, Up) and from Pin 3 (Down, Blue) and this fixed the problem.

Keyer started the FT-1000 scanning again. This time nothing would stop it. Cannibalized a male mic connector plug body from a bad Heil adapter, installed it on the voice keyer, and the problem stopped. Had help from Earl Nesbitt, W9ELN. Voice keyer performed fine in ARRL SSB contest on Sunday.
