Phil, your installation looks alright. It is almost identical to every Facet I've done with the exception of the Rx battery, so I don't think it's that. Kevin or Ed should know about the 50 MHz, but I have not heard anything about it.

Trying another channel is a good idea and you may also want to try the test with 72 MHz, (may be a pain to borrow another radio, but may be worth it from an informational stand point). It wouldn't need to be anything fancy either as it is only for reference.
