[Elecraft] KXPA100 and KX3 - strange behavior.\

[Terry Brown]

I just returned from running my KX3, PX3, and KXPA100 portable.  I setup the
three units at my home QTH anticipating a sked to Rarotonga, at 02Z and find
that my KPXA has the swr indictor blinking, and when I try to tune, it stays
at 1.6-1 and does not release the transmit, the red led remains on.  I am
not sure it is tuning at all.  I made the mistake of trying to tune with the
antenna connection not connected to my KX3.  It gave an SWR of 24-1 and
tried to tune, then I discovered my problem and turned things off.  I have
mistakenly tried to tune with an antenna unplugged with no problems.  Both
antennas were attached to the KXPA when I tried the initial tune.  When I
connected the RF IN to my KX3, then I had this problem.

 

Any clues to what is going on?  The SWR indicator continues to flash with no
RF to the AMP.

 

Thanks,
