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.

I had to disconnect the the squelch pin in my mDin6 cable to get the
FT-817 to work. There are some notes for the FT-817 HF SSB based AFSK
and 1200/9600 bps FM operation here:
Using the DRAWS hat, I have had good success with AX25 packet using a
Kenwood V71, for example, running XASTIR, or sending and receiving winlink
messages using PAT.
However, when I substitute my FT-817 for the V71, using the same cables for
data and rig control, the DRAWS DIN-6 connection appears to "short" the
audio from the FT-817 to ground.
