52Y is air to air for distance and bearing (had previous posted a list on this thread).
Thanks Terry, I have a list somewhere in my messy shack!
I guess everyone uses different color codes. Red to me meant classified information that wasn't encrypted, black was after it was encrypted. the different colors systems were kept separate to keep red info from accidentally being recoverable on black parts of the systems. (ie different rooms with minimal interconnections between them.

Are you guys using the pre-amps to make up for long cable runs or trying to boost weak signals? Do you get alot of overload on local freqs with them? Thanks

I use my Stridsberg Pre-20 since I run 15 scanners and an airspy with a 16 unit tv coupler. I have a local 102.5 radio station antenna about a half mile from me on the mountain, so I have a RS fm filter before and after the preamp. I need to get a 152 MHz paging filter; that's my only issue with rfi. The antenna is up about 40' with RG8 cable @ 75'. Every now & then I'll have a scanner lock up with another, but that's to be expected.
Both on my end.....yes some overload on some frequencies but I usually work around that. The PA feed uses a preamp for weak signals and on the airband you can hear other aircraft talking on frequencies other than the one the radio is showing. However, being less than 6 miles from KPHL and being right under the KEWR and KTEB arrival corridor - altitudes less than 18K....that can be expected.
