Is there a way to tell which towers are online or just assume that both towers are transmitting the same message at the same time on the same frequency
It's a simulcast system in testing phase. Every tower on the system will carry the same traffic when it is online. What towers are online right now will depend on what the county folks are doing at any moment with regard to testing and equipment deployment. Eventually all the towers will be online and will carry the same traffic when they are...hence simulcast. Between now and then, it's gonna vary.

Yep. It's two sites currently online in testing. The power was cut in half at Lima when the second site was kicked on for testing. Simulcast timing is still being worked on as well. We fell back to Phase 1 for the time being during testing that is occurring this week.
This is a 9 channel simulcast system so all 21 tower sites will have 9 base stations (Channels 1 through 9). In Phase 1 that would give us 8 consecutive talk paths with 1 control channel. We will be Phase 2 so you will have 1 of the 9 channels dedicated to control channel and the other 8 will function as 2 consecutive voice paths each allowing for 16 consecutive talkgroups to be transmitting at the same time before a user would experience a busy. Since all tower sites are in one simulcast cell you will only see this as one logical "site". If channel 1 is the control channel then channel 1 is the control at every tower site in the system. If a user transmits on TG 200 and the system assigns that to Channel 3 then channel 3 at every site will come up and transmit simultaneously. So that is correct... if you live in Radnor and monitor sector 1 for a pursuit that jumps over the border on 95 and in to Delaware you will hear it perfectly in Radnor.

Debbie was no longer doing Delco for a few hours.
About 5 times now, I've given " radio reference checks" and not a single person has caught it...... .Ya'll slacking
Thank you for the info
Strange question of the day...are both Lima and Rose Tree currently simulcasting the voice frequency? I am getting a weak but stable decode of the CC here at my house in NJ on both a Harris portable and a Unication pager. But neither one picks up the voice dispatches here at all. There's literally no reception coming through on it. But I can check it against the Openmhz feed to know there are dispatches going out. Is it just my location in relation to those 2 sites? Obviously things are going to be changing around but I am using this experience to test out some theories about reception.
I don't think the new system is carrying any operational traffic on a regular basis as they are in early activation of the physical sites. It's going to be a large system, so as the bring up each individual tower site, it needs to be aligned, timed, power adjusted, antennas aimed, etc. You might want to invest in some sdrs and a program like Unitrunker or SDRTrunk to watch activity on the control channel as the system is deployed.

Both should be simulcasting voice. However, it is currently in Phase 1. I don't think that matters for the Unication programming.
Thanks. Yup it does not matter. It is just another of the reception variance that can happen between control Channel and voice frequency at the same location in the same band.
I just got decode on an automated dispatch at my house on my G5 attached to the amplified charger. I am 26 miles or so east of Rose Tree in Berlin, NJ. That amplified charger Does help to pull in weak signals.
That's pretty good considering that individual sites generally cover an area of between 8 - 12 mile radius of the tower, assuming it's omni. Phase 2 is a little less. Systems are usually designed with some degree of overlap between sites depending on the desired grade of service, mobile on-street, portable on-street, and in-building coverage without BDAs, etc. - lots of factors.
Yea I'll say! I have a lot of trees around my area but a little opening to the WNW. I am using an 800mhz yagi pointed to the West. I also somewhat get Chester County 800mhz system here 31 miles away.
Hey Keith, I was polite...I said Thank you..
It did catch me off guard, though. I had to go back and listen a few times before I realized that it was directed towards us.
I see Debbie is doing Delco again...
A big thanks to Steve, you and the rest of the team. I don't think that I've ever seen this much info sharing before. It's especially nice for us retired/disabled, etc. first responders that no longer have access to the "official" gear and rely on the scanners, etc. to listen.
Once a first responder, always a first responder...It never leaves you...
The other voice wasn’t as nice as Debbie but that is just my opinion.
It’s always fun to “work the crowd” here and there.
Sorry, the phone is being stupid.
At least you have an excuse...I've run out of them...
