Can anyone else hear data (reflex) on 940.2375 or 940.2125 in your
area? How about some licensee data? None of my references list either.
Also, do they use reflex for things other then pagers? The length of
the data received would suggest it's going to a PC or something like
that..any input would be appreciated!

We have that in the Dallas/Ft Worth area too.
All I have been able to find out is that 940-941 and and 930-931 MHz
is allocated to Narrowband PCS. I don't know what it is or who uses it.

So, it might be safe to assume that one might find the RE in flex in
the 930-931 range..? Anyone got one!?

I belive what you guys are hearing is Narrowband PCS (NPCS). They use primarily
25 kHz or 50 Khz channels and are paired. The base talks out in the 940 MHz
range and the pagers talk back(milliwatts) in the 901 MHz range (39 MHz split
just like 900 MHz trunking). The frequencies are listed in FCC Part 24
specifically sections 24.129 and 24.130. You can get the channel info from the
GPO website.
I know Skytel has a nationwide system up and I believe PageNet and a couple of
other companies aren't far behind. FCC beta freq site might help you identify
the particular user in your area.
They typically send out multiple subcarriers over the same 940 MHz transmitter
and it really sounds brutal on a regular scanner.

Doesn't really sound that brutal unless the system is really loaded,
the only thing I can confirm is that the emissions are REFLEX.

I'll have to look harder on the fcc site for the owner's, a quick
search turned up nothing.

Might be a nationwide license and not show up at any specific geographic sites.
What were the exact freq's?

If you fo to the FCC Database web pageand look up microwave towers in your
area you will usually find that they ahve licsences for most of the
frequencies that you hear data on in your area.

The freq you guys are listening to is 940.2250 MHz. Honest. Its Skytel's 50 kHz
wide nationwide Narrowband PCS (NPCS) channel paired with 901.2250 MHz.
They got the license on a "Pioneer's Preference" back in '93 for free and now
the FCC is billing them $33 million because the Federal District Court in D.C.
upheld subsequent changes Congress made to the Communications Act that took
away the free ride. Not surprising.
If you look at the signal on a spectrum analyzer you can see 4 distinct
subcarriers which accounts for the confusing responses from a typical scanner.

Thanks for the info!

FWIW: it is REFLEX and could be decoded with pocflex if you were so
inclined.
