I just looked at my Discovery files for today and found a very interesting tone on TG 6000
( which I suspect is A1 ) it sounds like possibly a new priority response tone for PD or an emergency alert tone.

I can confirm this as well for that TGID at 12:13 today. Attached that transmission. The other PD TGs we've discovered didn't have that priority/alert tone. Good find!

Yeah I heard a guy say “test test” and then he played the alert tone so sounds like they are hooking things up!

Maybe we will hear more on different channels the upcoming week.

There was also a lot of talk on the equivalent of 7L but like before the 7L is secure / encrypted so no idea what they were talking about.

I added a slew of talkgroups to the system this morning, thanks to a submission. (Also added were several conventional frequencies.) If you guys could look over them and make sure there aren't any errors, it would be appreciated. (It's a lot of data entry, and even though I looked it over, it's possible I missed something.)

Also, all the talkgroups identified so far are using TDMA, correct?

Thanks,
Dave
It is a Phase 2 system, but some FDMA subscribers have used 7A1-7A4, maybe for testing purposes.

Thanks for your hard work!

You have really accomplished alot guys. I am absolutely thrilled. Ive been around the county for quite some time and am careful as to what I say. But with you guys around it is irrelevant ,(; Thanks so very much for that FLEETMAP. I have a UNICATION G4 I bought not knowing that it would not work on existing system . I bought it at the right price and decided to sit on it. Finally, thanks to your work I will get to use it around January 12th. Wait did I say that? Lol

Also the VHF patch for 7a 154.16 and 7b 153.950 remain in tact as normal. A matter of interest, 153 950 has an ongoing interference problem with some other radio systems in Virginia. Something is going to be done eventually it’s just nobody knows exactly what. I thought I’d throw that out there but as of right now not a matter of concern. Too many Volunteers as well as Career folks with Minitors and scanners to take away the VHF patches. We use Minitors in the amplified charge docks as backup station alerting system should the regular system go down.

Thanks Wireless!

also I just heard a Victor unit ( specialized unit ) try calling on TG6020 multiple times got no response and then called on 5D so more info that agrees with what we came up with in the google sheet.

On the new list, and important to me, we are missing hospitals. Hospitals used to be “79” will now be 7H. I just need to get numbers and hospitals.

I am not 100% sure if this is the case but it looks like the Holy-X-GT, Holy-X-SS, Mont MC, Nat Mil MC, SGAH, Sibley, Suburban and White Oak Freqs are going to be "Secure" According to the fleetmap that someone else posted I will repost below.

it says that red is secure. I also notice that the 7H and the Hosp FG name is in red but it then says EMRC, CNSL1, and CNSL2 are in black soooo I am unsure if EMRC and the CNSLs are going to secure?

I also am just assuming that secure means encrypted that is correct right?

EMRC and the MED channels are not going to be encrypted. Also, Zone 79 (Hospitals) on the SmartZone system is secure for in-county hospitals, but a few in DC, Howard and NOVA are not. Not sure how these channels are used - but for the most part, enc is probably not necessary unless detailed HIPPA protected pt. info is transmitted.

You all still cease to amaze FirePhoto the hospitals are a big deal for me so thanks . One of the reasons that I got my UNICATION G4 was the fact that only the driver (A1) and the charge EMT (A2) Are provided with radios in the ambulance. So getting this close to cloning an APX 6000 is going to be very handy for me to do my job. Now we need to get MCPD Dispatch TGs. By the way it appears that we have made some progress and keeping the police dispatch channels unencrypted. Some county council members are on board with keeping them unencrypted and supporting transparency

note: I should’ve gone to the frequency database first somebody’s already got the MCPD dispatch channels up it’s amazing how we went from 0 to 150 mph overnight great job again everyone I’m very happy!

Ok if you look at the fleetmap you will see MedStar DC, Childrens DC,IOVA and How cnty GH Adult and How Cnty GH Peds listed. The medstar, children's and INOVA contact I think are using the UHF Med Channels under NIFOG. The trick is to figure out which ones they are using. Yesterday I heard a mcfd medic unit talking to childrens on 72D and childrens signed off this is childrens hospital on med channel 39. Of course the trick is to figure out what frequency that is since med channel 39 is not listed. Does anyone have any ideas?

So far I have been able to hear clearly any unit who accidentally talked on the MCPD TGs so so far no encryption on the tgs yet

As I understand it, the 800 consult channels (72D and 72E) are not associated with any particular Med channel - they are "patched" at EMRC to either radio or landline resources. I assume it will be setup the same way on the new system.

Med 39 is a wideband med channel "Med 9" or "Call 1" 462/7.950 tone code D.

The Burtonsville tower site had climbers at the transmit antenna level yesterday - not sure why so much work is being done at that site.

I logged several radios (new RID range) joining police tgs in sequence yesterday - someone was either checking configs, training, or playing around with the new system, lol. No voice.

Can we assume that the "Great Falls x" tgs are actually hosted on the Fairfax County system as before?

Does the county run a VRS system in the VHF band? I'm noticing VRS 1-5 on the VHF zone. The 700 band DVRS is using a different channel reference series: DVRS 1A, 2A, 3B, 4B, 1C, 2C. 4D, 4E.

The "Great Falls" tgs are tgs on the Montgomery County system that only have a presence in Fairfax County (4) zones. Fairfax uses them as though they are Fairfax resources, but they are on the Montgomery system because our system provides better coverage along the river than Fairfax's does.

The only way a Montgomery County user accesses the Great Falls tgs is by selecting them in a Fairfax zone.
