Hugh - I would have thought the best solution would be to buy the
correct 4-pole 3.5mm jack plug. These are a standard item available
from all good component suppliers. In the UK we have them at

bring up a supplier nearer you.
Switch to SSB first, then go into the menu to change the MIC BTN parameter?

There appears to be a setting on the Configuration menu to turn off the
up/down and PTT but this is non functional. When selected on the menu by
VFOB the options on VFO A say n/a.
Here in the US we can order a Mouser 171-7435-EX 4-conductor 3.5mm plug.
Plenty in stock (over 2500). Cost is around $2.50 each plus shipping.
