Good Morning Folks
I have finally added a couple of K3 to the contest station lineup here
and just coming up to speed on how to use them. Had a K2 for a while
but big difference!
K3 100W, KAT3, 2m Module, Kiob, ser 00872 MCU vers 5.62 Has original
Synths and Sub rcvr .
Problem is no signal thru SUB. It appears to be working because I hear
normal background noise which comes up with RF gain and audio prperly
splits to right and left headset channels.
I went thru getting my head around the options for SUB antenna sources
and after deciding I definitely wanted to use the MAIN shared option I
opened the unit to check how the SUB aux antenna was connected. Removed
the TMP jumper to the KAT3.
Set config to ANT=BNC, pwr cycled, and selected BSET RX ANT is set to
MAIN. My understanding is this should share the main ANT1 or ANT2
selection of the main rx with the SUB.
All else looks to be in order inside but still no Signal from SUB.
Before I remove the 2mtr unit and lift the SUB out to be sure the SUBIN
connections are OK looking for any other things to check. This was a kit
build but had sat unused for a couple years after owner went SK. Clean
and looks good inside but no idea if it ever worked
Final thought was to try replacing the TMP connect to SUB Aux and KAT3
and reconfig for using the non tx ant to verify the SUB operation and
perhaps narrow the field to looking at the SUBIN connect and the Jumper
W4 situation.
Any ideas on where to go next with this?
Thank you in advance for any advice.
