The filter offset for 5-pole filters (like your 2.7 kHz filter) should be

filter.

Is this a relatively new KPA100, or did you purchase an older kit from
someone who never built it?
The reason I ask is because the older T/R switch design had elements
that could cause parasitic oscillations near 40 meters, and often was
most noticeable on SSB.
If your KPA100 has blue

Steve, thanks.
I'll investigate the suggested mod to the KSB2. Have you had to do this mod
yourself? Did those resistor values work out about right for you (1k0 and
1.5k)? Did the mod significantly affect the ALC action on higher bands?
I don't want to scarifice too much power out on 20m.

I have had the same thought, although I was thinking more of a
horizontal bandmap for N1MM that I could display above PSDR/IF and scale

What do you propose for those of us that use the Notch all the time? Should it
just be removed?
If there's this much trouble with toggling through filters on accident,
wouldn't it make more sense to have the tap XFIL button the APF on/off button,
and the HOLD the Dual PB on/off function? A

I've been enjoying the APF quite a bit.
My only suggestion, mirroring what some other folks have said, would
be to have it enabled by the "NTCH" button rather than the "XFIL"
button.
I find myself sometimes switching through the different filters when I
really want the APF.

Hello again folks,
Sorry about the barrage of posts from me. Just playing with my K2/100 #6998.
I've noticed that when operating in SSB on 40m, requesting any power 15-20
W and up will always give me 100W+ output, measured into a dummy load.
Voice peaks are higher and result in Hi Curr warning
Generally, when one purchases a product, its value depreciates almost
immediately in a downward spiral. Elecraft is proving that the reverse
can be true. The usability of the K3, terrific from the start,
continues to improve with each new firmware update (I'm discounting the
little setbacks).
Well...might want to compare the solar situation of "Back "in the day"" to
today. Your milage may vary.

I'm a 99.9% CW op too, but 10 W SSB will also amaze you.
Back "in the day" as SSB was first taking root, 10W PEP was a very common
power level. Even us old AM types (I ran a 1950's Viking Ranger) weren't
running much more. My Ranger did 65 watts dc input to the final, which was
about 40 watts RF

Hi Nick,
Because of its small size, the KX1 uses a 3-pole crystal filter. This
filter's opposite sideband suppression could probably be improved with
larger capacitors and an impedance change at either or both ends, but
this would come at the expense of SSB/AM reception.
