Hi,
I had a plan last year to convert my PSK20 to a PSK/CW rig. I was going to
add a VXO Xtal oscillator about 10 Khz lower in frequency than the existing
oscillator so that the output would be14060 instead of 14070. A switch
would select the VXO or normal xtal and provision for a constant carrier
would be added. Would work on both RX and TX. Pretty simple modification;
I even bought the parts, but I didn't have a Round Tuet. I'm glad I didn't
do it because I now have a KX1, so I can carry both a KX1 and PSK20 (and
Laptop) if I want to operate both. Come to think of it, I might as well
carry my K2 which isn't much heavier and everything is in one box including
the battery, I have at least 5 watts on CW and PSK31, and it saves a lot of
interconnecting cable, spare batteries and such. What we really need is a
uK2 with an output of 2 to 3 watts, maybe the size of a K1, and covering
20, 30 and 40. As for other modes, if a rig will transmit PSK31 using a
computer sound card, it will also do RTTY, MFSK, etc. with equal ease.

When I was tuning around today on my KX1, I heard the usual strong warble
around 14.070 and I got the brilliant idea to: plug a patch cord from the
KX1 headphone output to my soundcard input, launch PSK31 Deluxe, crack
open the AF gain, and boom, 5 QSOs popped up right away.
I know the thinking on omitting an SSB option from the KX1 is because
voice doesn't typically work reliably below about 10W, and an SSB board
wouldn't fit in the KX1 case. But like CW, PSK31 can work like a champ
even at 100s of mW.
So how about an Elecraft-designed-and-produced *outboard* SSB adapter for
the KX1, designed specifically for PSK31? On biz trips, I usually have
my KX1 and laptop--it would be great to take along one more little black
box and be able to work PSK31, while making use of the KX1's KXAT1
capability to match a hotel room random wire on multiple bands. (The
Small Wonder Labs PSK series looks exceedingly cool, but is rock-bound to
a single band and requires an external tuner for non-resonant antennas.)
Good idea? Dumb idea?
