[AMRadio] Protecting receiver (was WTB: Coax relay, 110VAC, aux contacts)

[Rob Atkinson]

Hope that Ray has it.  It is getting harder to complete the entire run
of ER.  Last I checked there were around a dozen issues that were out
of print.  I bought my complete run of ER about 18 months ago, minus
the out of print issues.  Eventually Ray told me they were not likely
to get reprinted because of the extremely high cost and the down
economy.  I even offered to travel to ER's office and make copies
there on a photocopy machine but he said he didn't have a photocopy
machine there so that was not possible.   I got him to permit me to
locate a local ham with the issues and let me copy them which I did so
I eventually completed my run but with around 12 issues copied and
bound with stiff covers made with yellow card stock.   OTOH, I am
pretty sure the issue with Don's sequencer was not one of the missing
ones.  It's great that Ray offers to sell reprints.  A lot of ham
magazines don't do that at all.
