possibly found a transmitter on a sale site: --Mbeam (talk) 10:20, 10 May 2016 (NZST)

With my new setup I can now hear this signal repeated 4-5 x with different signal strengths ( indicating from different locations )--Mbeam (talk) 05:36, 17 July 2016 (NZST)

spectrum of the audio sample on page. 3-tone MFSKMultiple Frequency Shift-Keying paging.

I did some research from your findings, and I have a few leads however unconfirmed due to the lack of information. It's a possible Motorola PURC/MICOR base paging station. This is based from the transmitter link you posted and frequencies seem plausible. I haven't been able to access if this mode is specifically PURC/MICOR, --Cartoonman (talk) 01:51, 18 July 2016 (NZST)

went backed at observed it a bit more , it does indeed sound like some kind of pager, i'll be adding a additional audio and iq file with it producing 2-tone and single tone dtmf type signals. absolute center frequency seems to be more around 154.463125--Mbeam (talk) 10:27, 26 July 2016 (NZST)

This sounds like that "central Texas receiving location" This might be for getting locations of certain things. Ywsia1

Whats the 'central Texas receiving location" ? --Cartoonman (talk) 09:16, 10 September 2016 (NZST)
