harford county/cmarc

Ok..after many hours and torn out hairs from my head, I have the answer..MOTOROLA SYSTEMS SUCK..
1.) The linear simulcast is causing the issue..
2.) Whiteford does not have 700 MHz coming out of it.. My closest site ( line of sight)

I took the 688 for a car ride to Jarrettsville along Rt. 165 from Whiteford.. In Whiteford its hit or miss at best..pass rt. 24 and it gets good..pass Fawn Grove road and you are in heaven ! All the way into and around Jarrettsville.. line of sight to the Madonna site..
So my programming is good, it's the Moto junk once again..
As for York and Lancaster, they are both P25 simulcast, and yes, they are 500 MHz systems.. They both are NOT Moto junk systems and they sound GREAT all over the place..

harf/cmarc

exactly right mr troymail... i am using ez scan. i thought it updated tg information but understand now i have to manually add new channels of interest. i am still learning these digital modes, harco./cmarc is doing good with some digital chop once in awhile/should be fine if i am travelling in the county.

police radio has come a long way since we handled howard county md pd on two channels from a PTT base to a 6 unit patrol shift! thanks again!

I have always reviewed my systems of interest in RR as part of updating. In fact if there are no chsnges indicated I probably won't bother updating.

Counties with changes are color coded and the changed systems and new talkgroups are color coded and I add them manually by reviewing the website.

I presume if I wasn't concerned about having all my manually tweaked alpha tags wiped out, once I downloaded the new database, I could just delete a system and add it back from the database if there were a loy of adds (like CMARC this past week).

Just as a side note, P25 subscriber radios with LSM compatibility absolutely love LSM- my APX gets the Baltimore County and City systems perfectly while my PSR flails in agony.

EDIT: Not that I would ever wholeheartedly actually defend Moto...

No motorola systems do not suck. Buy a real subscriber and hear what they actually sound like.

1.) The linear simulcast is causing the issue...

No. CQPSK is not the problem, the POS discriminator tap in the POS scanner you are using is what the actual problem is. Please educate yourself as to the cause of the lousy decode on CQPSK a systems.

So my programming is good, it's the Moto junk once again..

NO, once again it is the POS scanner that is the issue, NOT the system.

As for York and Lancaster, they are both P25 simulcast,

Are they simulcasting CQPSK a or C4FM?

and yes, they are 500 MHz systems...

the band they use has little bearing on how well they work! when built correctly.

They both are NOT Moto junk systems and they sound GREAT all over the place..

AGAIN, it is not the systems fault, it is YOUR POS scanner that was not designed to properly handle CQPSK(LSM).

Does anyone have the rest of the Fire/EMS channels for the Harford County P25 system. I heard the alert last night for the dwelling fire on Dembytown, but the RR database does not how all of the fireground channels.
Thanks

Looks like right now the answer is no.... You might want to put a Wildcard into your radio to find new talkgroups (or enable ID SEARCH if you're a Uniden user).

I cant speak for Lancaster but can assure you that York is C4FM and not using LSM. Kayn hit the nail on the head, LSM is a beautiful thing. The issues you see with a scanner (wide open front end, poor selectivity) arent an issue with even the lowest tier P25 subscriber. Systems are designed for their users, not scanners.

Additional tkgps

I have 4 additional talk groups for Harford county.

Fireground Tac channels are A6-A10, B6-B10, C6-C10, D6-D10, and E6-E10

I am still working on getting all of the talkgroups but as of now I have all of the primary FG response talk group for each company.

Tkgp A6. 10514. ( overflow FG Tac ).

Tkgp B6. 10521. (. Darlington , whiteford, jarrettsville, norrisville )

Tkgp C6. Already listed (. Bel air , Fallston )

Tkgp D6. 10535. ( level, Havre de grace, Aberdeen )

Tkgp E6. 10554 ( Abingdon, Joppa Magnolia )

Not sure how to forward this info so it can be added to the radio reference database. Can some let me know how to get these tkgps added?

Thanks. The biggest advantage for CQPSK is it allows for a greater delay spread, between transmit sites, with in the intended simulcast coverage area.

I just added all of the new fire / EMS talkgroups to the Wiki for the 700 / 800 system..
Anybody have any tricks for reliably receiving LSM with a scanner??

I have two feeds that sound like crap now..

 

[DisasterGuy]

The major issue is that a scanner doesnt actually benefit from the LSM so you end up hearing the TDI. You can try adding attenuation.

Try using a real subscriber radio, programmed to not affiliate. The scanners will likely sound like crap regardless of what you try to do

York will be 700 LSM by this time next year..

I inquired about using an XTS2500 for 700/800 and got the usual answer..will a P25 9600 baud enabled (flashed) XTS2500 do 700/800 phase 1 P25

Yes. Go to communications.support and read the thread over there to program it for no affiliation scan. You need to follow the instruction carefully and follow them to a T, and the radio will do what you want.

Even better, if you have the system admin do the programming, then affiliation would be ok if they give you a legit RID to use on the radio for streaming.
