I am getting up to speed on working NO-84 with my TH-D72a. My primary antenna system and radio is IC-910h with the Icom Preamp installed near the antenna. The 910 powers the preamp through the coax, and I tend to leave the preamp on selection on the radio on all the time.
I want to put a MFJ1702C coax switch inline with the 2m side so I can branch out the 2m antenna to my HT. The non selected port of the coax switch is grounded. If you accidentally ground the IC-910's coax with the preamp selected on, does it damage the preamp power circuit or is it tolerant of a short? I could not find a definitive answer in the manual other than the preamp may not activate properly. I know it wont power up the preamp.
Inevitably, if I have to rely on remembering to turn off the preamp before I switch to the HT to work NO-84, I will forget. Just want to prevent burning something up.
Thanks for any suggestions.
