Hi Folks,
I remember the subject of headphone pops and clicks being discussed
before, but couldn't find any consensus as to cause. I'm using N1MM ver.
10.10.2 and K3 ver 3.79. In my case (over the weekend, CWSS) there were
many random loud pops when I clicked on spots on the N1MM bandmaps
All:
In SS this weekend, I noticed something new with my K3:
When attempting to transmit a low power tune signal (I'm set for 10 watts
out on tune) below, say 3.520, the power out and swr meters begin to
oscillate wildly. Going above 3.520, everything looks and works normally.
If I key the

I also noticed this, but on 40m and I think on 20m. No 80m antenna this

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.

It will need more screen real estate than a standalone P3 could offer -
unless the proposed VGA output is actually a vga connector outputting
more than vga resolution. And even then that would require a dedicated
screen in addition to existing computer monitors. This would only be
worth it if

Tomy,
What happens into a 50 ohm dummy load?
Do you see any HI CUR messages?
Has it always been this way? Or is this a new failure?
Is your power supply voltage dropping significantly during transmit?

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

running much more. My Ranger did 65 watts dc input to the final, which was
about 40 watts RF

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

The K2 top cover has enough room for a KAT2, KBT2 and KIO2 all at the same
time. Have you installed something else in that space?

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?
Perhaps it's me doing something dumb, but the Notch function doesn't
seem to work concurrently with the APF; ergo my suggestion.
What I find with the XFIL button is that I'm inadvertently and
frequently toggling through the filter settings when I just want to
enable/disable the APF.
On Mon,
That's the problem dumping too many functions into one box, I think. I have
an Elecraft AF1 Audio Filter between the K3 and my phones. It's an active
filter offering the same bandpass characteristic as the APF using analog
devices except that it also offers two selections of Q.

Is there any way of making the ALC more aggressive on 40m SSB, without
affecting the other bands too much? I remember seeing a previous post
about this somewhere but haven't been able to find the details again.
Any suggestions?

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.

John,
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
The filter offset for 5-pole filters (like your 2.7 kHz filter) should be
printed on a paper slip attached to the filter itself. The 2.1 kHz SSB
filter is an 8 pole filter, and zero is the recommended offset for an 8-pole
filter.
