SkipSanders said:If it isn't clear, CTCSS is not compatible with DES (white noise) encryption, so there is no CTCSS tone on encrypted transmissions.
This, of course, is GOOD, for us, since it means you can use CTCSS to listen to the unencrypted stuff on a channel while not having to listen to more than short bits of DES noise.

mike_s104 said:hearing more this afternoon. again, only one side. anyone else?
EDIT: just heard mention on "stop fuel at 10k" and "clearance for engine start". I think its an input for one of the other know freqs for Eastern WV Regional Airport/167th.

rfburns said:Propagation conditions appear to be very good tonight. I'm hearing the House cloak room with a message to Representatives about how many minutes are left to vote on H.R. 1311. It sounds like paging, but so far I have not heard any paging tones. I'm scanning so I just may be missing them at the beginning of the transmissions. I've never heard them on this frequency before.
Also hearing MRB very well tonight. The MRB transmitter evidently is located on base and not at their mountain top site as it is just not strong enough on a daily basis.
Edit: Just heard some kind of digital preamble at the beginning of a transmission. I don't recognize what it is by ear.

Could be OTAR.mike_s104 said:This morning Customs is running their 10-10 mode pretty hard.
Over the Air Rekeying. Take a listen to this wav file. They seem to like to rekey in the morning between around 0530 and 0700. At least that is when I hear it on that frequency the most.mike_s104 said:and what might that be?
