I'll see if a firmware modification is needed. Meanwhile, use the switches to
cancel TUNE.

The table entry for the SIG menu entry includes instructions for S-meter
calibration. But there is a typo: it should say "Set for zero-bars..." not "See
for zero-bars....".

Conditions were pretty bad today, I heard!

The KX1 is optimized for low current drain and will have less audio than the K1
or K2. But you should have plenty of audio, especially with headphones, unless
you're using really inefficient ones. Earbuds are ideal (the latest ones from
Sony are about $15-19 and are very comfortable), typically requiring an AF GAIN
setting of 9-10 o'clock. Also make sure you have installed the shorting jumper
across pins 1 and 3 of J7. Finally, the crystal filter has somewhat greater loss
at low bandwidth settings. Even for CW use, I typically keep it between 12
o'clock and max unless there's QRM nearby.
