Re: FT891, FT817, Audio Levels, I/O Fail , and Documentation #draws #ft817 #hfmodes



Thanks for replying so quickly. Cutting the pin 6 squelch line did indeed solve the problem.

For some unknown reason I had associated the squelch issue with HF and did not check at VHF/UHF FM. 

Also thanks to John and Brian for additional info and references.

The advantage of cutting the black wire is that you can in-line a switch to restore squelch operation for non-HF modes.

Or pull the pin in one end of the cable.

This is correct.  In order to work with the 817, 857, and 897 in HF modes, the squelch line must be cut.   

I had asked if this could be done in software or by jumper and the answer at the time was that cutting the line was the only solution.

See msg 2079 — the SQL line is the black wire.
