Re: [Elecraft] KX3/KXPA100 issue

[David F. Reed]

Joel,

thanks for the help; typically I am not in the shack when this happens.
Software sometimes running WSJT-X, sometimes DXLab suite.
Firmware revisions: KX3 - MCU: 02.38, DSP 01.37 ... KXPA100 - 01.35

thanks & 73 de W5SV, Dave

Dave,

I run the same setup adding the PX3. First, I am *not* experiencing this with 
my setup. Second, what are you doing (i.e. software controls, macros, etc.) 
right *before* this happens? What version of F/W are you running on each?

73,

happens, let's say I have power set to 30 watts; the KXPA100 shuts down and to 
get it back up, I have to go to the KX3, re-enable PA MODE from Off to On, and 
and reset the PWR level from 5.0 watts to 30 watts.

My questions are:

1. Is anyone else experiencing this?

Any help appreciated.

Geoff,

Thanks for the idea... That might be it; I am not in the shack when it 
happens, though if that were it, I would be surprised, as I have the 
internal batteries in place, and I would have thought that the power 
doesn't go away if the external supply drops. Could be just enough I 
guess...


Thanks & 73 de W5SV, Dave

Make sure you turn off the KX3 before you shut off power supply.

[Elecraft] KX3/KXPA100 issue

[David F. Reed]

I am running a KX3 into a KXPA100.

It all plays very nicely except for one issue; on a seemingly random 
basis, it seems to lose communications between them in a big way. The 
KX3 has (without my doing anything) reset the PA Mode to Off, and the 
PWR to 5.0.  When this happens, let's say I have power set to 30 watts; 
the KXPA100 shuts down and to get it back up, I have to go to the KX3, 
re-enable PA MODE from Off to On, and and reset the PWR level from 5.0 
watts to 30 watts.


My questions are:

1. Is anyone else experiencing this?
2. What is going on?
3. How do I fix it

Any help appreciated.

Thanks & 73 de W5SV, Dave
