Hi Fellow Elecrafters,
My K2's internal speaker is now alive and well. I found the problem around
noon Saturday and I really felt like a big dummy. I had it plugged onto P5 of
the control board instead of P5 on the RF board (behind the on/off switch).
And, I know how/why it happened. So
I am building K2 s/n 4759. I apologize my poor English skills. Let's
hope you can help me.
The first test with control and front panel board was OK. Only problem
was agc voltage which didn't reach 3.80V but 3.79V. According to several
similar reports I decided to forget it.
Alignment and
HI I'm trying to apply the N4PY Computer Contol System to the K2. Its head

output of the PC DB9 socket (only one) and at the out at the DB 9 on the K2
(If more than one mode wold appreciate how to identify it.
An interesting post..who would have thought there were 2 x P5's ? I
see in the parts list the P5 for the control board is shown with a picture,
and the P5 on the RF board doesn't get a picture at all.
The masking on the boards doesn't say whether it is a Volt-meter or speaker
jack, but I
For those of us who use the K2 as a base station rig, or connected to a
hefty battery (like mobile installations), it's easy to forget that one of
the design criteria of the K2 was efficient use of power for
emergency/portable use. The other Excellent performance numbers were
certainly in mind,
I am in the process of building my new KPA100. I need to determine the KSB2

firmware revision. I need to have revision 1.06 or later.
Any Help

The KSB2 firmware revision can be obtained by first setting the SSBA
menu entry to BAL, then holding the VOX switch. (Return the SSBA menu
