Using icom style external tuners?

ve2dx

hello gang,

the usual 4 pin molex icom external tuner connector, as 4 pins, 12vdc, trigger(tune), key.

I am assuming I could hook it up to a 6600, using local 12vdc and gnd, key to one of the ptt input. Two issues;

1- forcing low pwr when the specific ptt is triggered.

- Can't find any way at this time?

2- getting a tune triggered?

- Tune output to the tuner from the radio, isn't available.

- Well tune can trigger one of the ptts as an output, but not specific to a tune function?

- but this output would trigger tuning on EVERY tx, not only tune mode :😞

- and if I could would trigger tune both internal and external ATUs at same time!

I guess could use an external device to trigger the tune, but would have to drop pwr first, and then back up… :😞

asn'asn't anyone got this going yet?
