I too tried the KBT1. One "minus" was my hearing asn't that good anymore
after years of working around jet aircraft and doing a lot of shooting under
a range shed (before cheap ear protectors were available! They were $125 or
more then...early 60's) Anyway the smaller speaker's output too low for me!
Another "minus" was the aggravation of getting the batteries in and out.. I
opted for an external 8 cell "AA" holder for NiMH 2 A/H cells. Also have a
small pack of two 6 volt 3.5 A/H gel-cells that works great.
The internal KAT1 coupler isn't very good for 80 or 160 meters. I use an
external "L" coupler that is heavier but about the ame size as the K1!
Don't do any "portable" 160/80 meter operation anyway as a rule. I may try
the "T1" seperate coupler anyway sometime this year just for fun.

That's 2130 K1 units since my number 175 arrived in November, 2000. I
ordered it in June, so I waited five months. It was worth it. I'm not
all that fond of the monotony of stuffing resistors and capacitors on a
PCB, so I bought the K1 in spite of it being a kit, rather than because of
it.

Best QRP rig I ever owned.
It's a real gem in the Elecraft line. I know of no other QRP rig that I'd
rather carry portable.
I have 4 band board (40/30/20/15) and a 2 band
160/80 meter board.
The roll-off of the elliptical low pass filters on the four-band filter
board is much sharper and deeper than that of the very simple filters of
the two-band board. I've never seen any spurious-output specs for a
four-band K1, but since the two-band K1 has the best figure for spurious
output of any Elecraft rig, the four-band K1 can only be even better. It
has better performance than the two-band 40m/20m board, and twice the the
available bands (including 15m, IMHO the best QRP band when open). How
could one beat that combination of *both* improved versatility and
improved performance?
If I did it all over again, I'd opt for the little
external tuner (T1?) instead of the internal tuner.
I really like the internal tuner, even though currently mine has recently
developed a yet un-diagnosed problem and now never returns a VSWR less
than 9.99, even into a dummy load. I tried the KBT1 for more than a year,
but eventually discarded it. I don't like sources of chemical leakage and
outgassing next to printed circuits.
