Yay! My K1 (4 band) #1870 is alive and well...
I built it last summer, after buying it at Dayton. Everything worked
great, and then 20 meters suddenly failed. Stone deaf and no output.
All other bands were fine including 15 meters, which shares circuitry
with 20 meters.
After 6 months of "living with it" I finally opened the case and checked
the 22 MHz crystal. I warmed up the "ungrounded" pin and lifted the
crystal away from the circuit board a little. I put it back together
enough to test it, and BINGO! 20 meters came to life and now works
great! Apparently a solder blob was under the crystal at that point,
grounding the pin to the case and thereby silencing the crystal.
I immediately worked Arkansas and England on 20 meters without a hitch.
The K1 is one of the few QRP rigs that would be comfortable as a day to
day main station radio - as long as 7 watts is all you need ;^p Listen
for me and K1 #1870 on 20 meters!
