Since the 8 MHz FT-243 crystals
were so cheap, many, if not all, the HW-29s were modified to take them,
and Heath quickly figured it out.

Heath produced a mod kit for the original HW-29, to add an 8 MHz
oscillator. As I recall, it was built on a bracket mounted using the
two holes on the front panel that originally held the plastic Heath logo.

I obtained a used Heath CB model similar to the Tener, and converted it
to a Sixer. I home-brewed the 8 MHz oscillator.

This was back in the 60s when the band was wide open. I did not have
the capability of measuring RF power, but would guess my makeshift
version of the Sixer put out about one watt.
