A few facts;

The system is NOT encrypted in total. A few police and a few fire TGs are; the majority are in the clear. The coded TGs are for law enforcement sensitive matters; administrative/command matters and patient (HIPPA) privacy.

So the statement "Due to the encryption, scanners currently used by citizens to listen to Sheriff's Office radio traffic will be ineffective" in the Sheriff's Department press release is not true?

I can only tell you what I know

Thanks for the info.

I can only tell you what I know. I don't listen to the police, but I am relaying the info I rec'd firsthand from a reliable source.

If the police are totally encrypted, it is news to my source and was not supposed to be happening for routine dispatches, etc.

Hopefully others can find in the clear TGs for the PD.

Encryption

Not to get into a debate, but from the preliminary zone map I have seen, of the 80 some talkgroups in the sheriff's office "zones" only 9 are non encrypted. ALL PRIMARY show encrypted. Even Animal Control shows encrypted, Fido might hear them coming on his trunk tracker.

It also appears FD will be encrypting EMS to Hospital comms - I'm fine with that.

45** do appear to be Sherrif's TG's
46** do appear to be Fire. Fire is doing lots of training so you should hear units playing with the TG's for the next week or so.

Interesting. Thanks for the add'l Info

Eng2Trk - Thanks for the added info. I have not seen the PD fleet map, but was going on what I considered a reliable and well-placed source.

I knew EMS to Hosp was encrypted, just as the "Admin/Command" TGs are, so the supervisors, etc. can discuss matters with little fear of being heard by others. As you said, that is fine by me, too.

Why the PD encrypted nearly all TGs is beyond me. Seems a bit non-transparent and perhaps paranoid in a time when transparency in Gov't at all levels is being pushed and talked about.

If we had a viable "Press" community in the county, beyond two out-of-county papers, perhaps they would be opposed and could make the change so they could be our "watchdogs," as they are charged to be and avoid putting out what the public authority PIOs spoon fed them.

I'm not saying the PIOs put out wromng info, but they can put out just some details and hold back others, A monitoring "press" can fill in the details and voids not released in official statements.

What can I say, I'm a big fan of open government and an unbridled press.I think our country is based on those principles and others.

Tdma

Well by reading the current addition of the "Capitol Hill Monitor"

http://henney.com/chm/0110/chm0110.pdf

It appears Stafford will be required to implement full TDMA by the end of 2014 since it is a 700 system. Good article about P25 Phase 1 and 2 and scanning. So listen while you can.

Final field training for Fire and & Rescue was today, still looking for Feb 1 cut over around 1000. Just in time for a snow storm.

Should be fun

That's actually a typo in CHM, the date is January 31, 2017 for 700MHz to use 6.25KHz efficiency.

It's after noon now, and Stafford Fire is still using their UHF-T frequencies. The only thing I've seen on the 700 MHz freqs are a few "LNK" indicators on talkgroup 4601 (which I assume is going to be the Dispatch channel).

Cut Over for Fire & Rescue

Cut over for Fire & Rescue has been pushed back until Tuesday Feb 8th @1000.

Wanted to get some procedures in place first and correct a minor codeplug issue.

So one more week of UHF.

Anyone know if other agencies (schools, public works, utilities, etc.) will be going to this system? If so, what is the timeframe?

Thanks,
Dave

The change from the "traditional" NoVa TG designation (4A, 4B, 4C) to Dispatch, Incident 1, Tac1A, etc. is due to technical changes at Motorola, not an outcome of some desire by the county personnel.

Could you explain this one?

I think the cutting out/garbled transmissions are because of the simulcast issues that several other P25 digital systems have (e.g., Loudoun County).

If somebody could let me know how the reception is in Spotsylvania or Fredericksburg, I would appreciate it. How does it compare to the 400 Mhz system? I haven't purchased a digital scanner yet.

I'm in Spotsylvania, a couple of miles southwest of Fredericksburg. The signal is very strong; however, the system seems to have the simulcast digital distortion problem. Many of the transmissions are choppy or garbled.

Hopefully the experience for the actual users of the system is much better (I'm assuming it is, since they're the ones with the "real" radios).

I am considering purchasing a digital scanner and providing a radio reference feed for all Stafford fire channels. Will it be worth the effort with the garbled transmissions others are reporting? Fredva, are you still considering the upgrade, and if so will you be feeding the digital channels to rr?
