[Elecraft] K3 Sub-RX Deaf on One Band

[Pete Smith N4ZR]

This afternoon I worked TX5S split on 10 and 15.  Tonight, I was hearing 
him very well on 80, but to my surprise my SubRX seems to have gone deaf 
on that band.  I've verified that it's still working fine on all other 
HF bands, including 160, but for some reason no 80.  The main RX and the 
transmitter are still fine on 80, which might help track it down if I 
knew what I was doing.  Any ideas?
