Green County: home patrol 2 not receiving p25 mode

[Kbbell]

I am a manager at a local Radio Shack store trying to help out customers
green co Wi updated county sheriff to digital 2 weeks ago
home patrol sentinel updated Monday 12/20 using version 12/19/2021
updated system then wrote to home patrol 2
3 miles from tower
squelch turned down
law dispatch is turned on
i hear it talking threw the live audio
tried it the the 10 mile range full data base , and threw a favorite..... no talking or blank signal (only heard 1 tone)
town talk (non digital) comes threw fine / ems page fine

what am i doing wrong

According to the database Green County sheriff is still analog on VHF. Since the digital information is not in the database the Home Patrol won't know anything about it. I would also suggest asking one of the administrators move this thread to the Wisconsin board.

The RR page for Green County mentions the county P25 system uses simulcast but I don’t see the actual P25 system listed. Agree with advice from @smithken and you may also run into HP2’s inability to deal with simulcast if you find info on the P25 system.

Hi & welcome to the RR forums:
Perhaps your county migrated to WISCOM here and nobody identified & submitted the updated TGIDs to the database? Just a guess as this seems to be the trend with many other states. Anyway, yes as the posters above me suggested, might want to ask for this thread to be moved to the Wisconsin Discussion Forum, maybe they'd have a better idea there. Perhaps you may want to scan WISCOM then enable ID Search on that HP-2 to see if any unidenfified talkgroups come through to see if anything sounds familiar (assuming encryption isn't a factor of course)

Oh, hmm...OK. Yeah definitely weird. No county-specific TRS's listed in the DB


No P25 listed at all aside from the aforementioned state system & it doesn't appear anything THERE is simulcast...

Looks like they are listed as P25 (not trunked).

Hmmm, I've never seen simulcast but not trunked ... but you may have the answer.

Ah I see it now, it's a miswording. Simulcast conventional P25 frequencies, not a "system" in the classic definition. Makes sense now

OP: Try these:

154.72500		KSB392	RM	230 NAC	GRSO1	Sheriff Dispatch	P25	Law Dispatch
155.61000	158.94000	KSB392	RM		GRSO2	Sheriff Dispatch	P25	Law Dispatch

Conventional P25 simulcast is quite common in parts of the US.

Conventional, non-trunked, P25 radio systems are quite common across the country, including Wisconsin.

Any scanner that isn't a Unication or an SDS100/200 is going to have poor performance on a simulcast system like Green County just activated.

It’s the simulcast twist that throws me for a loop, not sure how this system would be engineered.

Maybe he means simulcast on more than one frequency?

Or simulcast repeaters with voting receivers?

Let's keep the below message in mind please...

Posting company or priviledged information on these forums

Everyone, I wanted to bring one of our rules/guidelines to light because it seems some members are forgetting this fact. That fact is that there is a high possibility that your employer may be reading your posts on this forum. Some may not care and some will. Often in the radio communications...

Updates made. However, as Kevin points out above, be careful with the public release of said information. I see it came from the vendor that did the work.

i advised what i wanted it for and i had permission to forward it to y

Maybe he means simulcast on more than one frequency?

Or simulcast repeaters with voting receivers?

Transmitting the same information on multiple frequencies concurrently is not, technically speaking, simulcast...that would be simul-select or multicast. The term "simulcast" in the LMR world means multiple sites transmitting the same information on the same frequency at the same time and it can be on a conventional or trunked system.

Simulcast (when done correctly) requires extensive RF modeling of site location, antenna heights, TX ERP, terrain covered, amount of required talk-in/talk-out etc. so that transmitter launch times are synchronized to keep destructive interference to a minimum and/or steered out of a certain area.

It is, after all, FM - F***ing Magic

Happy scanning.

 

[ozzie]

Do you see any issues with monitoring these freqs with a Motorola xtl 2500 on conventional, as Motorola decodes simulcast very well.

The Green County system is working fine, it is, as advertised earlier in this thread, the fact that it's a LSM system. My commercial equipment receives it just fine.
