[TowerTalk] Intermittent on Receive Only

[john at kk9a.com]

This can be an annoying problem. It is a bad connection somewhere and
usually a little RF will temporarily improve the connection. It could also
be a bad T/R relay in your transceiver or amp. To help trouble shoot the
antenna system you need to determine what antenna settings cause this
condition. For example, if it occurs on all bands and you are using an
external rely box the problem is likely in the relay box or the feedline
going to it. If it occurs on only one antenna it is likely related to its
balun or feedline.

One of my antennas has a problem on receive, where the strength of 
signals will abruptly drop for a second or less and then spontaneously 
return to normal.  However, when I transmit on the antenna, it never 
shows any indication of an intermittent connection, even at 1500 watts - 
the SWR is still 1.1:1.

Is this a well-known way in which a connector problem can manifest itself?
