Very strong signal picked up in Greenville NC on SDRUNO with DSD plus 406.113 P25p1 NAC 971 TSDU ?
406.113
- Thread starter peten1vak
- Start date
Probably an image from ECUH medical center. The NAC for that system is 971 I believe. Are you seeing constant traffic like a control channel or intermittent traffic like voice channels that may include talkgroup IDs or subscriber IDs?

As Trumpetman indicates it could be an image, however that band (FEDERAL) the freq is invalid
406.1130 is likely 406.1125 or +/- at 406.1000 or 406.1250
see if you also hear it on the above with a Scanner or other radio vs the SDRuno
Back in 2012 there was a mystery TRS on 406.1125 heard in the NC/SC area Sys ID 01C - nothing since.
However the recent (2021 NTIA FOIA Release) indicates that 406.1125 could be in-use at Greenville for the Voice of America
but that is a one frequency pair allocation and not likely a Trunk

Yeah I'm going to punch it in the scanner and monitor it. Also something I never knew hearing ham on 414.441 and 413.877? Very clear extremely strong signal I guess I didn't know hams can go down this far?

if you are getting Amateur Radio in the 400-420 band, then you do have an IMAGE issue.
US Amateur Radio is generally 440-450 Repeater use with some other allocations in the 420-440 spectrum

Yeah it must be an image. I just can't believe how clear and strong the signal was but I guess that can happen. The 406.113 has now completely disappeared so I guess that's what's going on.
