Hi All

I have a BCD436HP. I have CHP programmed using Sentinel. I live right on the border of LA County and Ventura County. I have both areas programmed in, but can only hear LA County. I "think" i have looked through all the settings and they look the same with the exception of the frequencies. Any idea what I might be doing wrong?

Thanks for the help!

I live in the Western SFV and can copy the "Purple" from my location. Obviously, I can copy Teal, Tan, Brown and Black.
An old Radio Shack VHF-high 1/4 wave ground plane antenna at 20 feet with a BCD996P2.

I know it is not an antenna issue as I can hear teal. I believe it is a programming issue.

Here is CHP within my "Area" group which also includes Ventura Co Fire and Sheriff, LA Co Fire.
I normally only scan my "Local" group which only includes TEAL as well as LAPD, LAFD, Metrolink, etc.

It could be the location of the transmitters. If you're using the stock antenna you will need pretty much unobstructed line of sight. And if you're indoors it will also significantly degrade reception.

I can hear teal, but not purple. I actually live in purples area. Does that make sense?

Try removing the CTCSS from the channel. It might make a difference. I have all my CHP frequencies set for tone search and not for tone filtering. I pick up the CHP from mountain tops 65 miles away. I have a GRE-600, which works well for rural areas, which is where I live. Oh, and I have a rooftop discone antenna with LMR-400 coax. .

It all depends on which transmitter they're using. Based on FCC license data, it looks like the Teal has transmitters at Oat Mountain, Castro Peak, and Rolling Hills.

The Purple has transmitters at Oat Mountain, Red Mountain, South Mountain, Castro Peak, Geary Hill, Torrey Hill, Sisar Canyon, and Laguna Peak.

So it's possible you're hearing the Teal on Oat Mountain, and the Purple is using another transmitter site that you can't hear.

45.4 is your best bet. I am in Thousand Oaks all the time and still can barely hear their radio traffic. The only time I pick anything up well is when they broadcast/select Oat Mountain then it is booming.

Do they broadcast on both 42.4 and 45.4?

They use 42.4 for Ventura city area units, and 45.4 for Simi, Moorpark, Thousand Oaks, etc... but they are both transmitting at same time from what I can tell. Depending if units are on Purple 1 or Purple 2 is what the field units transmit on
