Speaking of the Heil Quiet Phone, I have a pair and found they were
subject to RFI. I largely solved the problem, in the process reverse
engineering the circuit. I'd be happy to share the details.
In the end, they're OK, but the passive Radiosport headset provides
better isolation.

I tried the Heil Pro 7 at the Heil table at Hamvention. They are very close
when compared to the Quiet Phone, which is essentially a Heil Pro with battery
powered noise cancelling circuitry. I still prefer the Quiet Phone for
DXpeditions, with ability to select quiet mode only when needed.
