[Collins] R-388

[Garey Barrell]

Kevin -

The R-388 manual is available at

http://www.kg7bz.com/Manuals.html

The crystal filter in the 388 is very sharp.  The IF must be aligned
to the crystal frequency.  It is also possible that the crystal itself
is defective, but much more likely an alignment problem.  All
described in the manual

Very nice receiver.
