Can anyone id these two frequencies as to the user(s)? They appear to be data control channels that sound like an EDACS system. Since I am hearing the Md. 162.5000 NOAA wx transmission relatively strong at this time I suspect the data transmissions are in NOVA or the Md. area. Previously in periods of ducting activity I have heard these same two data data channels but no other related digital activity indicating a TRS. They are relatively strong today with signal level averaging S5.
