Well I can tell you that ADCOM has switched.....none of our cars have access to the channels that we have had programmed previously....great safety move

I'm not really talking about the ISSI gateway so they a FRCC radio can talk to one on the DTRS, but if a FRCC radio will switch back to the DTRS if needed.

The ISSI gateway will allow talkgroups/radios to seamlessly work between systems. Kind of like network first but with no analog audio patching. P25 voice packets, RadioIDs, Emergency Activations, Patches, etc. will flow between systems.

A FRCC radio switching to DTRS for a specific channel is the interim solution they are using while ISSI is being implemented.

Based on the signal strength and coverage, my guess is that site 550 is Bennett and 551 is Hoyt.

The 1800' tower is the TV transmitter tower for the station that is licensed to Sterling. I've used the site for amateur radio contesting, but for front range coverage I like the school site S of Hudson better. Of course, that's not what Hoyt is designed for.

The 770.61875 (and earlier the 772.1687) signal is 5 bars on my handheld and rubber duckie inside the house W. of Golden. A very good signal.

No big deal, they just need to issue all cars new radios for VHF, MARCS, and FRCC. Wouldn't it be great to have 4 radios?

The ISSI gateway being implemented will allow for this functionality. Unfortunately the ISSI gateway can't be integrated on the DTRS side until they update the software on their system (they started upgrading last year and should be complete sometime this year). We'll most likely see talkgroups/radios roam between FRCC, MARC, and the Westminster system before DTRS.

Also, each ISSI gateway has a limited number of "talk paths" which will limit the number of talkgroups that can roam between each system. I know they are planning to implement ISSI for MAC & Network First talkgroups, it is still unknown what other talkgroups will be ISSI capable.

I do know that Westminster & FRCC radios are still programmed for DTRS to access mutual aid channels while the ISSI gateway is being implemented. There are also some talkgroups that have been patched as well (i.e. the same RID is used when you hear Metro Net traffic from DTRS agencies on the MARC system).

Thanks for the info. I have serious concerns about the audio quality and potential loss of transmissions when two gateways (ISSI & Network First) are being used together. Network First alone has already been proven to drop radio traffic when a talkgroup is being used by DTRS & EDACS at the same time. Adding a second gateway and third radio system to that equation can't help things.

On a different note - South West Adams was just dispatched and remained on North Wash Ground on their last medical, something may have changed with that talk group.

So are there 2 radio sites on the same tower at Bennett now? One for FRCC and one for the state? If not won't the state have a big dead zone?

From what I was told from a guy who was at the DTRS meeting last week, FRCC is going to start (as we can see) transitioning sites over as they get up and running.

The MAC channels will be available over both systems and the FRCC will have its own MAT channels. As for complete roaming, nothing has been said, but I am sure certain talkgroups based on location and need will most likely be setup that way with either a console patch or ISSI.

Yesterday it seemed like North Wash FG was used for fire tone-outs and other traffic that you normally hear on Primary Dispatch. I wonder if a few Fire Agencies were temporarily "sharing" a TG because of technical issues with the switchover?

From memory. On DTRS N Wash FG-A and SWAC FG-B were the same TG number. It's probably still the same on FRCC.

47300 E 38th is quite a distance from the Zap site, unless Zap has moved.

Is the Bennett site called "North Metro"? That doesn't seem to be intuitive. Perhaps the North Metro receivers just have good coverage around Bennett.

Wondering if the Broomfield made the switch over? The old list I had was,
TG-65 Broomfield PD Dispatch
TG-2 Broomfield PD-Ch2
TG-3 Broomfield PD-TAC
TG-4 Broomfield PD-DATA
TG-5 Broomfield PD-TAC/SWAT

Thanks for any info on this.

Took my other radio and lock in on TG-65 and there still on DTRS as of 8:43 this morning.

VHF is alive and well in 1A. Some days there seems to be more comms on VHF than on the 1A Tac. Sunday night during the I-70 mess one series of transmissions started out on DTRS 1A Tac and quickly switched to VHF. Except for ops with the aircraft I don't hear CSP 800 simplex comms. Maybe the VHF range is better. CDOT sure likes to use 800 simplex for ordering food and drinks etc.

Hmm, I thought DTRS was never supposed to have duplicate TG's, unless you're suggesting they "shared" a channel? Regardless RR reflects the following:

8 North Washington Fire Dispatch
9 North Washington Fireground
4146 North Washington Fire Department Training

33 Southwest Adams County Fire Dispatch
34 Southwest Adams County Fireground

I'm still hearing "primary" dispatch traffic on TG 9, so maybe they are making some changes. Also, I'm hearing North Metro Units on North Metro Ops A report they are switching to "East Primary", I've never heard that phrase until yesterday.

I believe busy signals will work for talkgroups interconnected between systems over ISSI. If a talkgroup is in use, other users will receive a busy tone and be unable to transmit regardless of what system they are on.

Also, the current network first talkgroups will eventually be purely digital once Denver transitions to P25. I believe the official "home" for these will end up being on DTRS.

It sounds like North Wash. FG was indeed being used temporarily for a Dispatch Channel, it appears that North Wash. FD & SWAC are now using their own TG#'s from DTRS...

Southeast Weld DTRS Site 3-058

I noticed a couple of weeks ago I wasn't picking up Southeast Weld (Keenesburg). While manually inputting in the alternate CC's, I got a control channel signal on 773.40625 and it showed site 3-058 on the screen. In seeing the control channel from the Adams Simulcast changed to one of the alternates, I would assume that this would be a change due to the FRCC.

The change you noticed may have been in preparation for Weld to cut over to the FRCC system. Weld was scheduled to begin using their new FRCC dispatch center Feb. 11th into Feb. 12th. Possibly Weld will be cutting over to FRCC the morning of Feb. 12th if all the bugs have been worked out.

You just reminded me the Weld County Simulcast changed control channel frequencies from 853.3125 to 853.575 a little over one month ago. My guess is that the Weld County Simulcast will re-appear on FRCC using control channel frequency 853.3125.

I just heard Weld Sheriff report a radio tech. arrived at one of the towers to work on it and will be there "all night".

Weld has started switching towers over to FRCC beginning in part with the Grover and Pawnee towers.
