PLAUDITS, 'way to go!

I've a $5 RAL from the '04 Hayton Hamvention.  Clean as all
get out but was passed by every surplus maven because 'audio tuner'
was awol - the variable center-freq. LC filter.

Took it home, powered it up & voila.  Results everyone claimed
were right.  Did tail-end set with the RadShack 'dsp' WF2U praises
so often - & it performed fb.

There's a lot to like in a RAL

BTW, did anyone here notice Joe 'cq calender girl' Veras wrote
up set in last issue.  W7EKB had a good half-column contribution
