[Elecraft] problem KRX3

[Don Wilhelm]

John,

Check the SUB-IN and SUB-OUT connectors on the KRX3 to be sure they are 
properly inserted and seated.
Also re-check the cables for the SubRX synthesizer.

Do you have the KBPF3 installed?  That is required for receiving the low 
band.  And you should upgrade the KBPF3(s) with the newly announced 
upgrade kits or order the KBPF3A and the two bypass capacitors for the 
regulators (one for the main RX and another for the SubRX.
