[Boatanchors] Mods to Knight T-60?

[qrv at kd4e.com]

If the carrier has been radically-suppressed but if a low-level
carrier is included (minimal carrier required to-be-determined)
then it's merely a carrier-suppressed AM (DSB w/carrier) signal
and should be detected.

However, is not a boatanchor HAM/SW AM receiver w/o a BFO (or easily
modified with one) common? Certainly all modern rigs have them.

The synchronous detector project is parallel to but not integrated
with the all-tube 160-10m project.
