Had a brief scare last night with one of my K3s.
Wednesday night I uploaded the latest firmware (3.57) to both of my K3s.
They both seemed to be OK, but as I was getting setup for the upcoming ARRL
SS SSB I noticed a bit of a problem. One of my K3s worked fine on CW, but
when SSB was selected I lost all RX audio. Additionally, the VOX appeared
to not disengage correctly. After some investigation, I was able to get
the RX audio to came back if I increased the width to over 3.2kcs. I have
the 2.7, 400 and 250 filters installed. I then deselected the 400 and 250
filters without any change. I reloaded firmware 3.44 with no help. I
reloaded my last SAVE CONFIG with no help. Getting close to panic now.
Then I got out the manual to see how to do a reset. The reset fixed the
problem. I then loaded my last configuration save. All still OK. Then
uploaded the latest firmware (3.57) and all still fine.
Not sure why - but somehow the K3 lost it's SSB mind. This past weekend I
used both K3s in the ARRL-SS-CW and had no issues at all. With the
exception of a couple 40cw Qs I have not been on the air.
Has anyone seen this type of issue before. CW appeared fine. SSB would
transmit fine in PTT, the VOX would not disengage and there was ZERO RX
audio.
As of tonight it is still working fine !
