I have noticed that if I turn my P3 off the RS232 out link to the PC also
stops.
Is this correct?

Hello Group,
I am going to give a short presentation to local radio clubs about my visit to

Folks, I've read this thread with concerns about the SLA battery in
the K2. However, the Elecraft web site says the K2 batter is a
Gel-Cell, not Sealed Liquid Acid. Does this make a difference? Were
some K2 batteries SLA and some Gel-cell?

Gel-Cell is an informal name for a SLA (Sealed Lead Acid) battery. They
are one and the same thing.

Hi Jim,
I'm using 1.09 but I believe this will also apply to 1.08. If VFO A is on
the left side of the screen then you must be in Fixed-Tune mode. In that

Yes, it does that on mine too. I'm using a microHAM Station Master and if I
turn off the P3, the band data goes away. The fix here is to turn the P3 on
then power off and on the radio.

Hi Pete, Check the RS232 speed settings in the P3.
The P3 forces (and leaves) the K3 at 38400 baud. If you have the P3 set to

I would guess that means you removed the cable from the P3 and connected

That still leaves the cable high on the suspect list.

Did you try the IF menu in setup? If you don't select K3 it won't

Yes, the HPS-1a is a great supply. But it's about twice the size and

A wall wart supply would be fine as long as it meets all of the
