7106 / Bay Bridge LIVE as of 0645 this morning ...


Update: 7121 is MdTA Bay Bridge "C"

7126 is the already identified Port Tac but is now looking like a "common" group for multiple areas including Bay Bridge

Not currently being heard on the BALTIMORE site (101) -- it's on AA site (102) - which makes sense- and I'd suspect (although I don't know for sure) it's on the Queen Anne's site....

Curious -- anyone up in northern Baltimore County, Harford, or Cecil? What are you hearing?

Yeah that was a convenient little incident to figure out the TAC TGs.

WHOA.... on 8568, somebody talking about texting somebody to their radio from chicago, using the internet as a link from there to the FiRST system. Then a question about whether he can get webpages on his radio, answered with "only if you have the full display model." Drool.

8568 seems to be a FiRST Team testing related TG.. at least for now, unless they're testing on that TG as they set it up for another end-user.

Has anyone taken a listen to the old MdTA UHF freqs to see if they're still being used (maybe simulcasting from FIRST), or are they dead?

Department of Transportation Scanner Frequencies and Radio Frequency Reference

As I scan this thread, I didn't see anything about the Hatem or Nice bridges (although the way things are going, it would appear they too will show up on FIRST at some point)...we need to update the DB with this...Mike

I asked about other MDTA detachment in an earlier post. They may or may not be active yet.... If they do go active, they may could well be out of range for me to receive.

We should expect another set of users soon- maybe tomorrow.

I am REALLY interested in when MSP and Kent County are going to show up....

Certainly sounds interesting...but are we sure the techs aren't just messing with us (would be surprised if someone didn't read this forum) just to see who is listening?

Just saying...

I heard this also. I'm pretty sure it's real. These new systems are just "private cellphone" systems anyway. How many of your cell or even home phone calls traverse the Internet these days? Probably a lot more than you think....

Ok,
Just thinking before the morning caffeine. Yes, I know it's an IP connected world...for better or worse. I can't remember when the last time I talked on a twisted pair phone was. Home is Fios, work is Voip. I suspect that in keeping with the purpose of the system connectivity outside is in place to telco,internet and the like.

The entire idea with Region 1A is to get ALL MdTA detachments operational by 1 Jan, as their current UHF system has to narrowband or cease operation by that time. So, though they might not be in range for us up here at AA and BCo, Hatem and Nice will certainly come online as part of this region. MSP barracks M R and F are also completely covered by Region 1A and should come online as part of this group (though I expect they will be a secondary priority to getting MdTA off UHF.

Going with that @Mike, MdTA UHF is not simulcast at all with FiRST, and the frequencies have generally gone dead with only sporadic transmissions as they migrate. I expect the UHF system will be accessible until the end of the year when all of MdTA moves, and then it will likely be deactivated.

OK let me ask this in a different way - are the old 450 Mhz freqs still up, maybe simulcasting from FIRST (it wouldn't be the first time something like this was done when a system was in startup mode), or are they dead? At least the ones for Harbor, the Bay Bridge and McHenry.

I realize it may be a tad early, but I - like LOTS of other people - have to travel north in a month or so for Turkey Day. There will likely be lots more changes in the interim. However, the database needs some updating, I think, to include a FIRST link from the MdTA freqs...Mike

I'm told the Kent radios will be installed during the month of November - and the Kent system will go live in December.

No getting much on the system from Northern Balto Co - - just some occasional MSP M transmissions.....not sure if the Balt area towers are simply not being used/tested much - or if it is an issue with reception on a ducky where I am. Will attach a yagi to my 800 sometime this week and see what else I can get. What I have copied does sound clear - great decoding by the PSR-800.

haha I guess I didn't phrase things clearly, my bad. No they are not simulcasting MdTA TGs on UHF. However, the UHF freqs for migrated detachments are still usable, and I have heard occasional transmissions on PORT, FMT, and BAY UHF. As I was trying to say, this will likely be the case (not simulcast but accessible as a fallback) until all of MdTA has migrated and they hit the deadline on 1 Jan. Does that answer your question a little more clearly... or am I still fuzzy?

Since yesterday I seen at least 240 hits on 7106 (BayBr) and one single hit on 7135. Unfortunately it wasn't long enough to identify anything meaningful, but I'll keep the recorder set in case anything further comes up.

Has the opportunity to travel the ICC (I95 to I97) last night. The only active control channel is the Anne Arundel site. Signal wasn't that good and was going by the time I reached I97.

Since the MdTA on the ICC is on the Montgomery County trunked system, I suspect the AA site (102) is being extended for now to cover the PG end of the ICC. Time will tell....

It's Thursday -- did anyone notice any new users/talkgroups today?

as I dig through my 1600 recordings from the last day...

9420.. which I'm pretty sure was somebody listening to or a patch to BCo Detention Center A. The RID that came up was a 225xxxx ID, which is Baltimore County portables.

MdTA VRT unit on 7150, 7116, both keyups no voice. MdTA Inspector units on 7121 BAY C, which I'm beginning to think is the Inspectors coordination TG, not a police TG by function. MdTA unknown 7125 novox.

"BWI 3" came on the air for a radio check with PORT, suggesting that they're starting to be issued Phase II capable radios.

However I think they cooled off a little bit, no new consistent users added.


"Has the opportunity to travel the ICC (I95 to I97)" Uh hang on the ICC doesn't go that way. Oh wait you meant MD 97 I think. Never mind, I'm with you now.

This id was based on units on the MdTA Bay Bridge talkgroup during the propane tanker incident -- units called each other on that talkgroup and said "call me on 'C'" (or something along those lines) and then the appeared on 7121 -- when done they went back to 7106
