[BC] BE AM-1A Transmitter Air filter Heads-up!!

[Mike McCarthy]

All due respoect Randy, that stuff is not very good.

If you want good filter media on a "order to spec" roll, go to

tridim.com

Their tri-deck media is tops in keeping dirt out and is moisture
resistant.  They sell their media in any width (or framed size) so long as
you order a case.

My sites and TX's are a LOT cleaner as a result of their higher efficiency
filters.
