tylerwatt12,

A couple of your Talk Group tags conflict with info in the rr database.

TG56081: No listing in the rr database. I checked my scanner and I don't have any hits for 56081.
FYI: The rr database has TG56080 as Burke Operations. When I checked my radio I show hundreds of hits for 56080 going back to May when Hopkins and Burke went live.

TG56064: My scanner does show hits on 56064. I have it listed in my radio as Hopkins Field Services. Since 56064 is not listed in the rr database there must not have been any reports from other users corroborating my id as Field Services.
FYI: The rr database has 56065 as CLE (Hopkins) Utilities.

TG56398: I have heard radio (testing) traffic (twice) on this TG identifying it as Middleburg Hts. Fire Dispatch. But... the majority of traffic on this TG has been radio tests, with various radio id's.

One last comment. Just because a TG or Tag is listed in the rr database doesn't mean that the entry is accurate. If you feel that you have monitored sufficient traffic to justify a change, please do a Submission to update the database.

The traffic on Region Inter Op Call In is snow clean up at Hopkins. They have front end loaders cleaning up the plowed piles and putting in trucks to haul it away. They are working by Concourse D.

Why is this traffic on Region Inter Op Call In???

I'd like do a little database cleanup in GCRCN. There've been a few talkgroups added lately that don't have very much "meat" on the description. For example, there are several Burke talkgroups where all we have is 'Operations'.

Can anyone provide a more detailed description for these? Are they numbered? There's also a few for the water department that could use some more detail.

Thanks! Keep up the great detective work everyone!

TG56398 Middleburg Hts. Fire Dispatch is Active

Last night I monitored two dispatch calls on Middleburg Hts Fire TG56398. Today I have monitored several additional fire dispatches.

Sounds like Middleburg Hts Fire is done testing and has gone live.

FYI: TG56398 was added the rr database yesterday.

TG56478 Radio Tests

Monitored several radio tests on TG56478. The radio id's were 1875xxx.

The first tests were with a radio id of 1875105, the test sounded like an analog patch with slightly muffled audio, background noise and a squelch tail at the end of each transmission.

The second tests were with a radio id of 1875307, this radio sounded (digital) clear with no background noise and no squelch tail.

While typing this post I just monitored a third set of tests with radio id 1875100, the audio was somewhat muffled with echoing.

TG56081 Burke Ops??

I've monitored traffic on TG56081 which is currently labeled Burke Ops for the last two days. So far all of the traffic that I have monitored on this TG is field maintenance related.

Yesterday and today the traffic on TG56081 has been devoted to snow removal from various area's of the Airport. The traffic was between supervisors/managers and equipment operators (workers). I haven't heard any traffic from Operations on TG56081.

FYI: The traffic that I've monitored on TG56080 (for the past 7 months) which was labeled as Burke Ops back in May is of a higher level nature (Operations to managers and supervisors). Burke is just too small of an airport to have three operations TG's.

From my perspective I think that TG56081 should be changed to Burke Field Maintenance or just Burke Maintenance.

Anyone else monitoring the Burke TG's please post what you are hearing and what you thinks about the TG labels.

Region Talk Groups

Can somebody explain what all tbe Region talkgroups are for? Happy Holidays.

I don't know what the official designation is, but here's what I've monitored over the last 10 days.

Region 2 & Region 3 have both been used by CPD for operations similar to what we hear on CPD Surveillance TG's (undercover work, drug busts, etc..). On the days CPD was using Region 2 & 3 the Surveillance TG's were busy with operations.

Region Interop Calling has been in use yesterday and today by snow removal crews at Hopkins Airport. Normally this type of traffic would be on Hopkins Field 1 or Field 2. Both of those TG's were busy with traffic for snow and other issues.

In both of the above cases the Region TG's are being used to handle over flow traffic from system users. So (for now at least) it looks like the TG's are available to system users when their full time assigned TG's are tied up.

I suspect that as time goes on we'll hear additional activities and users on the Region TG's.

I live in Cleveland (Westpark) and have a discone antenna mounted 30 feet above ground with good coax connected to two BC996T scanners via a Stridsberg multi-coupler. I found out after much experimenting that this antenna system may have actually hindered my ability to listen to GCRCN.

I noticed that I wasn't able to pick up ANY traffic depite full signal strength. I tried using the telescopic antenna plugged into the back of the radio that came with the scanner and found that it immediately solved the problem. I think I could be too close to the GCRCN tower sites, and my outdoor scanner antenna system was causing the scanner to become overloaded. The P25 audio and decode is very good too, hardly any garbled transmissions. I thought I might post this in case people in Cleveland or close to a tower site were having the same problem.


It would not be a case of being 'too close'. It must be that on the outside antenna you are hearing trash from who knows where blocking the vocoder. Or you could even just be hearing multiple sites, and the design of the unit just isn't allowing for good decoding, because it's simulcast.
I've noticed similar on an old analog scanner here in Middleburg. Many times, I can hear 800 and 900 MHz traffic better on whip plugged into the back than on the discone outside, because of trash. Networks, w-fi, cellular, etc, RTA and the 800 mutual aid channels are good examples. But of course it doesn't work that way on VHF and UHF, which is more important to me. So it stays on the discone.

I heard the Hopkins snow removal traffic, as well as other varying comms, which got me wondering...

Is "overflow" an actual capability of the system, i.e. do the radios automatically switch to these reserve TGs when needed? How would this work?

Over flow was just the way I phrased it. I'm not aware of any system setting to automatically transfer traffic based on Talk Group load to another Talk Group. Sorry for any confusion.

During one of the shift changes I did hear a Manager/Supervisor announce on the Hopkins Field 2 TG to the new shift, to make sure their radio's were on the "Regional Call in" channel.

Ah, gotcha. The Regional channels did sound like a mishmash of somewhat unrelated traffic.

Changed to BKL MAINT -- Maintenance

Airfield Maintenance? Building Maintenance?

Many larger and/or busier airports have those functions separated out on separate talkgroups since airfield maintenance involves FAA clearance.

At CMH we're using CMH AFM for airfield maintenance and CMH MTX for building maintenance.

Burke not a big or busy airport

Burke isn't a large airport by any measure. It's more like a bus station with two runways. The air traffic at Burke is private planes (mostly single engine prop), a few Company planes (small twin engine jets) and some helicopters (Cleveland PD, Metro Life Flight, Cleveland Clinic, etc..).

Since Burke and Hopkins went live last May, my scanner shows just 4 TG's for Burke. I hadn't posted Maintenance/Service TG earlier because my scanner shows 37 hits, not much traffic for 7 months. For the same period, Burke Ops 289 hits and Burke Fire 377 hits (there was a crash training exercise this fall that accounts for most of the fire and ops hits).
