[ARC5] Mil Headset noise blanker

[JAMES FALLS]

I have a TCS and a BC-375 and would like to use a headset while using the dynos for obvious reasons. Problem is, whenever I PTT, the relay noise is like a gunshot/ pair of icepicks in my ears  makes my head ring for several minutes.

Anyone got some sort of "impulse blanker" idea for this specific problem? The TCS noise unit (depo mod) does really well w/standard ignition hash, but PTT will have me bleeding from the ears..............

Thanks!
