Power output problem with K3
Locked
 
|
I suddenly developed a RF power output problem with my
K3:(
The power output just drops to zero. A quick power
cycle fixes the problem temporarily. (not enough time for the K3 to cool
off)
These are the things I have done so far.
There is no error message.
If I don't use for the transmitter for quite a while
it continues to work much longer.
1. It happens on any band and with different
antennas.
2. It happens at 5W as well as 100W
3. It happens when transmitting into a dummy
load.
4. It happens in SSB as well as CW.
5. Antenna port 1 or 2
Has anyone else seen this problem?
Can you think of anything else I should try?

Re check the configuration of the filter used in
transmit. I had a similar problem when I first put my K3 together.

In reply to this post by n1ix
I replaced the power supply and the problem hasn't
occurred in over an hour of CW use.
I did get one error message though. It flashed "BATT LOW".
I retightened the connection to the power supply and have not seen it
again.
