Not that I'm aware of

I thought the whole purpose of rebanding was to relinquish the frequencies.

You're right, I just refreshed my memory here: Rebanding - The RadioReference Wiki

Read something on the GRE Web site about the update. The radio can only decode 2 channel TDMA and not 4 channel or something like that. Don't know if the Philly system is 2 or 4. What a pain.

[W2GLD]

Philly is only a 2-slot TDMA system and the PSR-800 works fine with this system. In the future, I would expect to see 4-slot; but that's a really, REALLY long way off, especially for Philly, who still needs to replace a great deal of subscriber units in order to fully implement the 2-slot TDMA features fully. Whether you have a PSR-500/600/800 or their Radio Shack equivalents; you'll be fine for at least a year or two.

I believe the 2 fire and medic bands, j band and possibly t band were carried on both zones, even with the old system, if i remember correctly.

Does anyone have a timeframe on the Phase II transition?

So should i add talkgroups for medic,fire j t band on both sites?

[fourthhorseman]

Yes,
in the event of a failure the system will fall back to the other zone.

[mikedel83]

When programming the bcd396 using arc software it doesnt list zones, they are combined sites. Will these conflict having both sites under 1 system or should i make two seperate systems?

[h8tdigitalradio]

Program each Zone as a System with the duplication of TG's. Do not combine both zones as one System as the BCD396T only sees the one CC, and never sees the other. You can put both Systems under the same SQK. The BCD396XT is capable of Multi-Site Trunking and can have one set of TG's, but multiple sites.

I thought 'simulcast' systems use the same frequencies. Just programmed the system as a single system (both sets of CCs), to seen what I could pick up in S. Jersey (near Camden-Burlington Cnty border). Just using 2 wildcards.

Picking up transmissions from both sites (verified frequencies). Will try holding on a TG to see if transmissions switch from 1 to the other. Using PRO-106.

Yes they do. I was explaining how to program PHL's 2 Zones which have different CC's. The BCD396T does not support Multi-Site Trunking.

Using PRO-106.

Which supports Multi-Site Trunking. Should not be an issue.

Anyone got the Home Patrol-1 programmed for the new system?

Yes, go to uniden's site and download the Sentinal program if you don't have it already. Once downloaded apply all database updates, also update the Home Patrol 1's firmware and install the new database's. In my opinion it work's subpar compared to the other handheld and base model's that Uniden offers.

[phillydjdan]

I need some opinions from Uniden, GRE and Radio Shack users who scan the new system. I have the PSR-800 scanning it, and when on the move the reception is absolutely horrible due to the simulcast issue. How are the 396's and Pro-106's handling the new system when moving?

[soberbyker]

Can't help you with moving but stationary my Pro-197 is doing just fine.

I have a question about trunking, what is the difference between a "group" wildcard and a "private" wildcard?

[ampulman]

A private WC is a transmission directed to an individual, not an entire group. It is the same as an I-Call (individual call).

[phillydjdan]

On an interesting side note, the new analog simplex "South Analog" frequency is also licensed to Atlantic County NJ's EDACS trunked system. Tonight I am picking up transmissions on that channel (with the tell-tale end tones at the end) on my conventional 800 MHz radio. I know conditions are favorable for skip tonight (and my radio is connected to a rooftop antenna), but hopefully this won't cause a problem for the firefighters, especially since they do not use a PL or DPL on that channel.
