Yes, another log thread - only this time its only from less than one day of monitoring and from Church Hill in Richmond (a high elevation point). I know a lot of these have already been IDed.

Lots of 152.xxxx school repeaters popping up now. 152.300 is a mess when Yellow Cab transmits at the same time as the HCPS repeater. They're certainly making use of the 7.5 kHz "split" narrowband channels. I know there is heavy use of CTCSS/DCS and the equipment being used by the systems themselves are a bit more selective, but adjacent-channel interference/QRM was rampant, especially in the 152 MHz region with all these active repeater systems.

464.500 [162.2Hz PL], 467.900 [167.9Hz PL], and 467.925 [71.9Hz PL] were all incredibly active with construction and crane control related traffic. Lots of mixed Spanish/English comms. Somebody (presumably a supervisor) would call somebody in English and they would respond in Spanish. I have noted this on 451.8125 [452 DPL] in the past as well. Some of the construction supervisors clearly speak Spanish nearly fluently to be able to switch back and forth with such ease. It seemed like both 467.900 and 467.925 were used by several different groups or teams at the same construction site.

Anyway, on to the logs:

152.300 [d445] should be Hungary Creek Middle School. I'm surprised how far they carry.
152.9075 [d074] - This appears to be a middle school (I've heard 8th grade mentioned) and it appears to let out at 3:15 which would go with Henrico County.

151.985 [d143] I feel fairly sure is Thomas Dale HS

Great to see your logging. I going to program in a lot of your hotel related stuff in hopes that it can be chased down later.

Thanks N4JRI,

I eventually had to lock out 467.875 [67.0 PL], 467.900 [167.9 PL] and 467.925 [71.9 PL] as they would lock the scanner up every time. I also got tired of hearing "cable down..cable down...cable down" over and over again. Even listening to the construction traffic for longer amounts of time gives little clues as to the actual users of the frequency/tone (that is, which company/contractor it is). The fact that these are basic out-of-the-box "job site radio" frequencies makes it even harder.

I know Crowne Plaza Hotel uses 179.9 PL and I've logged them several times. They have excellent radios (or an excellent location). Philip Morris also uses that same PL on 464.825 [repeated] and several other frequencies but it is helpful when an organization uses the same PL for all things as far as IDing them goes. There's several large construction projects going on the VCU area and downtown (and at the University of Richmond, where I suspect the 451.8125 [452 DPL] temporary repeater is located, due to the mentions of "River Road". Still have not completely IDed that user either, even though they're just as chatty as the guys on 464.500/464.550/467.875/467.900/467.925.

I've noticed that common/default frequencies/tones are often used by several groups at once. 467.925 [67.0 PL], 464.500 [67.0 PL], 154.570 [67.0 PL] and 154.600 [67.0 PL] are all great examples of this. I know 467.925 [67.0] is used downtown but also used by Bow Tie Movieland for ops/security, and probably by other users later in the evening for bar/nightclub security. 154.570 and 154.600 are the default frequencies for out of the box Motorola MURS jobsite radios, although nearly all construction traffic I've logged seems to be on UHF.

Having said that, here's some logs I made yesterday (over a course of roughly 2 hours in the early-mid afternoon:

School Freq

159.8475 [d114] is used at John B. Cary Elementary, and possibly at Open High School. Most schools radio use should peak at dismissal time. In the city, that's 2:45 for high schools, 3:15 for middle schools, and 3:45 for elementary schools.
