Dear Elecrafters,
I'm still having problems with the subRX in K3 #2887. Occasionally when I
turn the subRX on, it appears dead, only it's not really dead, just
resting/pining for the fjords because mysteriously it usually springs back
to life when I power-cycle the rig.
I thought it might be a recurrence of what happened before i.e. the subRX
worked OK on every band except 40m (re-soldering the 40m bandpass toroids
seemed to help that), except now I'm trying to use it on 10m, where it has
been working fine for days. And changing subRX bands makes no difference
now. It looks permanently comatose.
I have had ERR DSE a couple of times with error codes E037979 and E027979
(curious coincidence? Or I might have written the first one down wrongly)
and E03000C. I've tried re-loading the firmware, loading the whole set
(3.11) each time as there is no easy option to just reload part ... The
first time I re-loaded the K3 Utility reported failing to load DSP2, the
second time it worked OK but the subRX is still dead.
I also now have the flickery S-meter thing that I noticed when the rig was
first built. It is flickering very rapidly up to the end-stop, even with no
antenna connected, and whether the subRX is on or off. Looks decidedly
sick. I've noticed this symptom occasionally in the past week but it
usually goes away of its own accord.
What can the panel suggest? I'd really like to continue monitoring 28020
and the 10m beacons ...
