Not really. AGC SLP 000 still produces significant AGC action. See K8ZOA's

Hi Ruben,
I use samlex 1223's for many years, mainly on my expeditions and also
with K3. You have to know that there are PS's made in BY which look
exactly like the original 1223 but they have no output filtering and
they have a different 12V connector. They do have a noise issue,
I have been noticing a similar anomaly since 3.76.
The only difference is it happens when I go to 2.9.
As I increase the width I see the filter switch at 2.8 (I have the 2.7 SSB
filter and 6.0 AM filter) and then at 2.9 it goes dead until I advance it to
3.0 and from then on it continues as it

Sounds familiar! Your K3 serial number is low enough to be one that may be

Just a shot in the dark: Have you checked your filter configuration?

I've been meaning to query the group about this for some time but the latest
episode has finally prodded me into asking.
I have noted before that when I ran the utility program after closing it and
then trying to use my logging program, the log couldn't connect using the
serial port.
Hi,
Yes, I have the same problem and Elecraft has been made aware of it. I
almost never use the utility for anything else than downloading new
firmware, but I can believe that the program opens the com port whether it
needs it or not.

Jeff: Thanks for the suggestion concerning the K3's filter configuration,

Utility, FL3 is enabled for LSB, USB and AM in both receivers. Another point
to keep in mind is that FL3 is only selected at a BW setting of 2.7 kHz or
Dave indicates that the problem occurred when the pileup consisted of four

S9+25-30
Yes.
For non-portable use how about a K3 Pro or K3 MK V++ that clips a few
circuit traces and has a daughter board that uses two or three filter slots to
house a stout IF amp, an H-mode second mixer and a PIN attenuator before the
