conclusions.
I think it was Don(?) who cited having problems with Berg, JR and Sombra
Rx's. These are pretty well proven units. Lots of guys are using them
successfully. Yet, Don had problems with each. This is a RED FLAG

It could be the antenna. The only way to improve the situation is

It also may not be the antenna although changing the antenna

Don't forget one other factor. Landings. Enough hard landings is enough
to damage any crystal, or even pop them out of an RX. Even and ex WC can
do that one.

I have two film cans full of receiver crystals. Problem is I don't know which brand of receiver they fit. They all look alike other than the color strip on the end of the paper tag. Some have white-tipped tags, purple-tipped tags, and blue-tipped tags.Is there a way to identify the receiver

Since (I think) the Airtronics stuff allows one to choose the shift, try
a JR 700. I fly the 770 (PCM, but otherwise identical) and it's

1. The power lines in question are on the west side of the road which runs
along the west side of the field; the winds were from the east, so we were

It is entirely possible that the energy generated (EMI/RFI - from DC up into
the GHz) by such an event could adversly affect RX's OR the TX's.
The more likely reason the RX's have been compromised has more to do with
circuitry that is already powered up. The additional energy may exceed the

As previously mentioned, damage to devices that are not initially powered up
should be fine. However the path of the extraneous noise (from the event) does
not emanate equally, therefore a device which was near another which was
adverely affected may also be fine. It is a hit-and-miss affair.
The receivers that would not work after the incident were not powered up
when the incident occurred. Those people who were flying at the time have
reported no radio problems.
