I use a lot Pactor winlink SSB and I have not any accelation on the
standard zinc corrosion.
Important note may be : I have no connection between ground straps and
boat negative (engine body) neither the TX is grounded to negative or
to strap, just the antenna tuner goes to gnd strap.
Counterpois is based on two external plates + boat keel,tanks etc
coupled via capacitors
Hope it helps

After checking my zinc anode, I'm fairly certain I'm getting
accelerated erosion of my shaft zinc anode when transmitting Sailmail
e-mail via my HF radio and PacTOR modem.
Sailmail and the PacTOR modem drive the HF radio (an ICOM IC-M710)
fairly hard.
Does everyone transmitting with a PacTOR modem suffer accelerated
erosion of their zinc anodes? Or is this something specific to my
installation (and can be corrected)? If the latter, what should I look
for and correct?
Cheers
