I installed the synth stiffener, and now have the following err msgs:

V PL1 *0.0
Assuming that it's not about "is unit plugged in?" and "wiggle the plugs",
which I have done, is there any advice?
I have the sub rx, so I swapped the two PLL c
Regarding the use of filters on RTTY:
> None of that is surprising given the nature of cascaded narrow filters
Has anyone seen much difference between the FIR and IIR filters?

I am getting K3 sn 2308 sorted out. It has no mods, but all current
firmware. I just installed a new version sub receiver board. The
installation went fine.
The main Rx has a 2.7 kHz 5 pole in FL3, 400 Hz 8 pole in FL4, and 250Hz 8
pole in FL5.
The sub Rx has new 2.7 kHz 5 pole in FL3, and a
I would like to suggest that the good folks at Elecraft consider making
paper manuals an optional item at check out time. It could save a little
money and paper, and some like myself are more inclined to download the
info in any case. Especially with radios that are evolving, like the K3,

I have a KAT100-1 with serial cable. Firmware 1.04. Works prefectly. Some
small scratches on the left side, otherwise clean. $200 includes Priority
Mail + insurance to North America. I can take paypal or whatever. Email
directly for any more info.

My problem here turned out to be an incorrect value for C34, which was why
the CW time constant was so far off. Now all is working normally with the
proper value. Thanks for this great support forum. It is definitely part
of the value of the K2.

That was it. The previous owner had put in the wrong cap in the cw
bandwidth mod (.047uf instead of .01uf) and that made all the difference.
Key waveform now good, and power control is stable.
Thanks for the great support effort. It makes all the difference, knowing
that there is no problem
Further testing here. I tried changing the control board MCU to the
previous firmware version, and no change, so that is ruled out. But... I
do notice that my keying wave form is not right. The rise time is very
slow, about 50ms, the falling time is about right. And the keying sounds
like

It's the same in cw as in tune. I can't reliably set the power at any
place but max. For sure, definitely not normal operation.

I have a base K2 sn 1056, with a to b mods, including cw shaping mod, and
the latest firmware. I have removed all options to ease troubleshooting.
Turning the power control gives erratic power output, varying widely and
randomly as I turn the control. If I turn the power control to max, then
I have just received a new old K2 here. It has most of the important mods,
AtoB upgrade, and is working as well as it can, as best I am able to
determine. The alignment is fine, and it puts out OK on all bands. I have
not been able to find any posts about the sensitivity on 15m-12m-10m being
