I live 30 miles south of Richmond, Va., and have mast mount preamped antennas towered mounted at 110-120 ft. I hear a lot of signals. Mainly I use a 996T digital scanner and R7000s for analog reception and checking for I/O relationships, etc. For the past several weeks I have been logging what I am hearing on vhf/uhf in scan search modes mainly from NOVA, DC and MD. Ducting results here tend to favor north to south signals and rarely south to north signals.
Morning band openings have been generally quite good for the past several weeks until about 10AM when the ducting tends to dissipate.
This morning scanning UHF one trs signal caught my attention as it sounded like an analog LTR system. I eventually logged all 6 frequencies of the trs. The default channel appeared to be 407.3750 mhz. I just checked the RR database and see it is the federal smr National Mall site. RR lists this trs generically as a LTR Passport site.It is not. The Air and Space Museum is LTR Passport and cannot be monitored.
Am I right or am I wrong? If I am right the RR database info site needs to be annotated one way or the other with a footnote for the National Mall site indicating it is a "regular LTR system". If I am wrong then I am hearing LTR Passport audio.
