No, the roofing filters aren't superfluous even with lower level
signals. If you set the bandwidths similarly as I do all of the time,
the rejection of the filter adds to the rejection from the DSP. I think

Subject: [Elecraft] K3: SSB vs. CW/DATA A with TVTR
When running my K3 with my DB6NT/Kuhne transverter on 144MHz IF out is
set to 1mW. That's o.k. for both CW and DATA A (WSJT), when 1mW is good
for 25 W out at the TVTR. Thats perfect for my 2x GU74b amp.

Udo,
If you are measuring average power rather than peak power, you will see
a marked reduction in average power with SSB even though the peaks are
the same power as CW and DATA.
Set your microphone level in the order indicated in the manual (you can
use TX TEST). Set Compression to zero, the

TU to those who responded to my question. Had to select the BIAS in MIC
selection. Great to have such nice help.
I have owned my K3 for two years and just now got around to putting it on
SSB. Read past the instructions on how to set up the microphone. Works great
with the Heil electret boom microp

Feature ... PTT puts the K3 in transmit using the selected mode
(e.g., USB). The CW input puts the K3 in transmit using CW.
That's why CW VOX (QSK or semi break-in) needs to be forced if
SSB+CW is enabled.
Unfortunately, the K3 lacks independent front and rear (mic vs.
ACC) P
I seem to have encountered a conflict between "SSB +CW" (i.e. CW
whilst in SSB mode - useful sometimes on 6m) and PTT. I have my K1EL
WinKeyer configured to assert PTT during CW. It seems that CW in SSB
mode is "muted" when PTT is asserted, so I get a short "blip", then
stay in TX, but no CW tone.
It is feasible to implement SSB auto-clarifier (Spot function on SSB)
on firmware of K3?
I'm a researcher in Digital Signal Processing and based on the work of
Robert Dick ("Tune SSB Automatically", Robert Dick, QEX, January 1999,
pp 9-18), i wrote code to do auto-clarification in real time and tr
Try a different mic. I had an element or wire break in my Heil headset
the other day.

Might also want to try Line In as a source to see if it works.
This might isolate the mic itself or the mic input circuit as the
problem.

Hi Roger,
What microphone are you using? If it is a MH2, it requires Bias to be
turned on in the K3 menu.
Also, what are your mic gain and compression settings?
You can also switch the source for K3 mic audio between the front panel
and the rear panel in the K3 menu.

My K3 does not work on SSB. All other modes work just fine. I downloaded
latest firmware thinking it might help but with the mic connected to front
jack and/or a headset connected to rear jack neither one of them work. With
key on mic it does transmit but no audio comes through. Any ideas before

I would generally agree with that. The RX in the K3 is excellent, the
IF filters are excellent, the audio chain is quite
Hi Mike,
I have posted some of this information to the reflector before, however I
will copy it again here. Basically, there is enough adjustment to make the
tx sound any way you prefer. However, it worked great for me "straight out
of the box".
Here is an email I received about it after working
I would take a listen to a K3 on ssb mode and compare it to others
before deciding.
A flat RX equaliser setting sounds terrible with aggressive white noise
on my K3, using good quality headphones and/or ext speakers.
The pink noise roll off setting for RX equaliser as per ;
