[R-390] R-390a Image problem?

[Jon Schlegel]

Tony,

Looks like KBJD is 10 kW non-directional daytime and 1 kW 
non-directional at night so that would reduce what your receivers see 
by 10 dB.  If that relatively small reduction is enough to kill the 
birdie then it sounds like the receivers are running close to edge on 
their signal handling capability.  What is the R-390A's strong signal 
capability?
