[Elecraft] K2 - No Signals on 7MHz Band, All other Bands OK

[Mark Raybould]

Hi,



I have not used one of my K2s ♯5459 for 4+ years which I now find has no
signals on 7Mhz band.  The K2 is built with KSB2, K160RX, KDSP2, KAF2, KAT2
and KNB2.  An FT817 is used as a band comparator.  I changed the Real Time
Clock’s battery on an age basis as it was the original and at least 6 years
old.  1st Tap of DISPLAY shows “C1 nr”, 2nd Tap of DISPLAY shows voltage
13.6 and current 0.34.  The Receive Ant is OFF.  The background noise on
7Mhz band is much higher than on all other bands which is much more bass
sounding.



Has anyone any simple checks that I can do before I get the test gear out
and confuse myself.  In advance, thank you for all your help.
