What are you using for an antenna?

Since I do not normally listen to EMS I cannot help you with that question. I think PB has two EMS services.
I have a discone mounted on the side of my house, so that shouldn't be an issue.

Medic One uses cells for their dispatching, so there is no hearing them at all.

Since last Saturday, this is what I show: The only frequencies I've been getting hits on are 859.2375, 857.2375, and 854.2375... All from the "Water Tower" site.

Still hearing gaps in transmissions on occasion. So, there is still some setting that must not be right.

Until you can pickup Site 2 (VA Center), which I am pciking up with the same setting as you, you will be missing half the traffic.

The ICOM Discone antenna I had needed a moderatly strong signal, cables do go bad especially if out doors and radio frontends can get weaker over time for various reasons.

Tuesday several PBPD mobile units asked for Radio Checks, a few hours later Radio Service was testing the system. I do not know if it had any thing to do with the VA signal strentgh problem.

Also, Tusday night during the rain i noticed that Site 2 was only 2 bars of signal strength. The RSSI showed it was 24db weaker than Site 1, which means way over 100X weaker. I was still able to read everything clearly but I am in town.

I am going to get my BC 436HP & SDS100 portables to see if they can even pick up VA Site 2.

Big News!

I used my BCD436HP with a 800 MHz Uniden stubby portiable antenna, (7 " long) and it Worked!

I used the same Favorites List I posted but I did have to find a "hot spot" by moving it a bit. The first Site 2 broadcast was only 1 or 2 bars and ProScan reported an RSSI of 89 but when I moved it a few inches and held it there it was between 200 & 315 RSSI. Site 1 was 435 RSSI, 5 bars and steady in both positions.

If you have a portable antenna good for 800 MHz (or a phsical antenna that you can collaspe to the right length), put it on your scanner and move it aroud to try and find a hot spot. Don't forget most coaxial cables will eat 850 MHz signals like candy.

Thanks for the info on EMS! What little I listened to it I knew I seemed to be missing some traffic. I have heard a lot of snow plow operators are using Cell Phones because thier plow radios over load thier radios if they get to close to each other.
