David,
Bandwidth might not be a good argument. I'm not convinced
ALC transients are a major universal problem with SSB
signals when they are compared to other reasons for
bandwidth problems. This isn't the appropriate forum for
that discussion.
I have looked at ALC overshoot because of my

I have now removed the front panel, reseated the aux DSP, replaced the

This is the second time my K3 has developed a fault out of the blue and
it is expensive (increasingly) to return things to Aptos for servicing.
I would be

WHY? The K3/100 is 1900. For $100 you would buy the Kenwood - NOT.
Actually, the K3/100 is $2150. Plus $100 for the
500 Hz filter. Plus $330 for the antenna tuner.
The K3/100 ends up being almost $800 more.
Think we should wait and see what kind of performance
the TS-590S actually delivers.
I placed my order for a K3 at Dayton yesterday after talking with Wayne and a
few others at the Elecraft booth. Wayne is a very popular guy, so I had to
wait for an opening a couple of times. Seems like these guys couldn't even
get a minute alone to get something to eat! Wayne was very helpful
Don't forget tho that the K3 has the option for you to build it yourself.
Then you know how it goes together and you save $250 over the fully built
version in the process.
Then there's the fact that the Kenwood is a catchup radio that's not even
finished yet, and once it goes into to production
This one is a bit hard to describe, so please bare with me.
I was talking to some locals (1-5 miles) this morning on 80m LSB.
I was told that when I was tuning up a hum was heard on my signal
by the guys, which were in LSB on their receivers
I tried with low power 1w
I tried with higher power
If the TS-590 uses only two roofing filters and has the best receiver specs
out there, then I speculate that it could be using an H-Mode mixer, that
the roofers exhibit better than average in-passband and skirt IIP3 followed
by a decent strong IF, plus a LO whose phase noise is suitably low
Bad power supplies, check for hum from them. Ground radio and/or power
supplies. The A/C hum has to come from the wall supply.
That's my two cents, good luck.

Sometimes hum will be induced from transformers in the vicinity. Run
the K3 on a card table by itself and see if the hum follows you.

I think $800 more for the K3 versus comparable TS-590 may be about right, I

No new menu settings need to be made or changed as a result of the DSP
upgrade or the IF buffer mod. Just make sure you that if you have the subRX

The second half shows how the problem goes away when the K3 is locked in

Well at this point I have:
gone on battery power
nothing is hooked up to the K3
except the 12v power lines from the battery
all reports of a hum on my tune signal
have come from stations 1/2 mile to 3 miles away
my output power was varied from 1w to 100w
only difference was the hum was louder
