[amsat-bb] RF Quiet my digital recorder

15 Apr 2011


      I am using an Olympus digital audio recorder for logging LEO passes,
because I can directly transfer a .wma to my PC from it (versus the
tape recorder I used in the 90's).
I am using an extension clip-on mic. I am finding that it generates a lot of
RF crud on 435, enough to swamp the RX if I am not careful.
Beside a torroid on the mic cable, and maybe a foil/mesh cover over the 
recorder
(maybe one of those new-fangled RF-ID protecting wallets),
anything else I should try?
