Inexpensive SWL recievers

[Gary L. Sanders]

The BFO control on the GR-64 is advanced to increase sensitivity to just
before oscillation occurs for AM reception; for CW/SSB you advance the
control beyond the oscillation point. This is the way the regeneration
control works on regenerative receivers. That's what I meant.
