Doug:

I have been operating on the 6 meter band and 72 Mhz since the mid-70's with turbines, DF's, props, and choppers....originally Kraft Radio, and now JR 10X....never had a failsafe lockout on 6 meters, or 72 mhz for that matter....did lose a Hotspot and a Bandit since 1999, but both of those were battery/switch/regulator failures.....

In the last 2 years I have had 2 glitchy receivers and 1 glitchy TX that required service......the RX glitches occured at Superman and Ozark Mountain, and the TX glitch at my home field......immediate response from all around was that I was "hit".....wrong......just bad components......

My buddy almost lost his ES earlier this year.....one aileron would go full up intermittently...first time it happened at a FlyIn...everyone jumping on interference as the cause...I thought it was more likely a servo, but turned out to be a bad RX.....

So don't sell all your 72 Mhz stuff yet.....
