Gents,
I have a Heathkit GR78 here, which is quite lively on most bands. But
the top band 18-30 mHz is near deaf and almost impossible to align. Anyone
very familiar with this rcvr?
Cheers,

Is that the portable, the one that came out in the late sixties or
very early seventies?

If so, keep in mind that it becomes a double conversion receiver on
that top band, and maybe it's not an alignment problem but that the
conversion oscillator is not working (the mixer stage for the extra
conversion is a stage of straight amplification on the rest of the bands).
