Hi Wayne,
Just downloaded MCU 4.18. Great improvement and everything is ok now.
Once again many thanks for the tremendous support of the Elecraft team.

We've now fixed this and are re-testing the code. Should have a new
beta release later this evening.

Successfully downloaded MCU4.17 and began experimenting with APV. It
took awhile to find a weak CW signal - 20m band must be in good shape.
I did find one that was pretty spotty reception in 2.8-KHz bw; a bit
better with 400-Hz. Then is turned on the APV. I could see a
definite improvement o
Nate et all,
I stand corrected. Looks like K3 #2730 also has this issue. I didn't
notice at first, but then noticed it last night. Performing a TX calibration
didn't really fix it completely, although it did help.
Glad to know that the boys at Aptos are working on it.

On Thu,
Phillippe,
You state the mic gain setting and the compression, but for the K3, the
most important setting is to obtain 5 to 7 bars on the ALC meter with
the compression turned to zero. If that is not done as the first step,
then the K3 cannot properly control its power output.
After setting
We're working on the SSB issue.

Aihe: [Elecraft] K3 MCU 4.17 (APF beta) kills SSB output?
I updated my K3 to MCU 4.17 beta last night along with DSP 2.65 and FPU
1.4(?) and now today I notice that my SSB output is down about 3 dB. I
can only coax about 50 Watts peak out of it and I&#x
After many tries, on Dummy load first then with distant Ham friends, conclusion
was to re-installed MCU 4.14.
Instead of giving the same dynamic with the MH2 microphone, with my Amp on,
using 12w drive, using Mic=2 COMP=20, pronouncing the number 6 slowly, I have
seen immediately the difference.
I have the same experience that Philippe has. I thought I had one or both
3cx800A7 tubes going flat in my amp when I had to increase the drive to a
level I never have been close to approaching to get 1KW out.
It's great to hear that you guys are on this new glitch so quickly.

it seems strange that I
would only need to do this after installing Beta 4.17.
APF works great, but I need to resolve this SSB power issue. I may try RTTY
next to see what happens in that mode.

OK, my SSB output was low too. I'm on phone so rarely, were it not for
the reflector, I'd probably never have checked and when I did find out,
the thread would have already died. I did the TX Gain calibration as
Wayne suggested, all seems to be well on all bands. Apparently, the DL
in my MFJ

Please retry TX gain calibration on affected bands. This is the usual
cure for a difference between CW and SSB power output.

At least some of you aren't seeing this. :-)

I had no loss of SSB power output after the 4.17 Beta install. The APF
works wonderfully, with only a hint of ringing to my ears. Really nice
addition to the K3.

I am unable to duplicate your conditions, I am only able to get APF on
in CW mode. Wonder if this would be something where a previously
uncontrolled memory bit is in an undetermined state, leaving a strange
"remembered" condition when those bits are used for the first time?

Interesting. Thanks to Jim for finding that setting Dual PB to Nor will
correct this. Hopefully, Wayne is reading this thread. :-)
> IO have
Power fine here with 4.17. Get full 100W PEP out on both CW and SSB and the
drive power that I normally use for my amp is as accurate as it always was.
Checked two K3s with an Alpha 4510, an LP-100A and an Array Solutions
PowerMaster. I don't see anything different at all regarding power
calibrat
I don't have any lack of ssb power output here after the new download with
APF enabled in config.
IO have to say I think the new APF is very good indeed. Running 4.17 on the
K3 and 00.41 on the P3.

I'm new to all this. I noticed a lower output last night as well,
after the ...17 load. Should we do a calibration and configuration
after a FW update? Time to get out the SG2 again?
...bc
BTW: the APF looks real cool. I'm not a CW operator, but this makes
me drool a little bit.
..nr4
I went through the CONFIG menus to see what might have changed while
in SSB. I found DUAL PB had APF on. I was unable to turn it off while
in SSB, so went back to CW mode turned the APF off (nor) and returned
to SSB and all was normal. Full output.
I have confirmed you can only turn APF on/
In a word, yes

Additional testing shows that when I set my power down to 5 Watts and
then back up to 100 Watts results in a max peak output of 50 Watts on
SSB
Additional testing shows that when I set my power down to 5 Watts and
then back up to 100 Watts results in a max peak output of 50 Watts on
