The anonymous homebrew xmtr I picked up at the AWA meet last
spring has finally make its first QSO, heard 589 in Texas by KE5HQ on 40
CW, but he reports what I sort of knew anyway...the rig has a chirp. The
oscillator is an electron coupled 12BY7, crystal controlled. What are
the cures for chirp ?? Slightly detune the buffer ?? add caps to the
power supply. Trying the easiest things first, how should I proceed ??

The easiest first check is to try another crystal.

This is the only xtal I have for 40 meters. I can (and will) try
it with others on 80 CW.
