[Elecraft] some strange behaviour with K144XV

[Johnny Siu]

Hello Group,
 
My k3 comes with K144XV internal 2m transverter.  I seldom used it in the past.  However, in my recent operation, I notice a strange behaviour.  There are occassions where I push the band bottom up to 2m, no RX and TX from the K144XV.
 
After power off the K3 as well as power off the powerr supply for a few seconds, the K144XV works again when I power it up.  Sometimes, when I switch on the 'SUB' for second RX, no RX and TX again.
 
At this moment, I am not sure what sort of sequence of buttons will lead to this happen.  However, each time, I can solve the problem by power off k3 entirely for a few seconds.
 
I am still not quite sure how I can duplicate the problem but I just ask the K144XV users here for similar strange behaviour.
 
When the K144XV functions, it RX and TX beautifully.  I tried to shake the TMP cables connected to the internal transverter but could not duplicate the problem.
 
Any ideas?
 

TNX & 73,
