Reception Issues....

[cowboymike1971]

ok this is strange, maybe someone can help. I'm losing the signal on the Snohomish TRS. I'm right in Woodinville,( almost on the county line) yet my scanner acts as if I'm in Portland. Heres the deal. I'm running one outdoor antenna with Belden coax. If i run that straight into the BC780XLT it will not pick up the system. If I run it into my older, splitter it works awesome. yet all UHF/VHF comms are deaf using that splitter, So I went to Radio Shack and got a T-Adapter and some RG 58-w/ BNC coax(6ft lengths) to run the 2 scanners from one antenna. I have all my UHF/VHF comms back but Snohomish TRS is dead, won't grab the CC. Yet all the King County TRS system works awesome. Its maddening. what is the issue here? is it just the CC channel? and why would it grab it with the older,ragedy splitter( very crude concoction). Its just scanning thru all the SNO TRS system and not picking up anyhting. I'm thinking its an issue with the SNO TRS and not my radio or my set-up. Any help would be great, Thanks.

Trunking Troubles???

Well, I can tell you that it's probably your scanner, Because if you change things with your scanner and the problem comes back/goes away, Then it must be your scanner, and not the TRS.

Not sure that it is the scanner. Seems to be working fine. The only issue seesm to be with The SNO TRS. its not getting a good signal to pull in enough to get the Control Channel. It does get it from time to time but comes in and out. it will scan TG ID's but then drops the CC and just starts scanning the Freqs. Everything else works fine. I did swap out my old configuration for an updated one. I have the antenna coax running in to a "T"-Connector then have two short runs into the 2 respective scanners. This seemed to "clean" the signals for mosy all the other freqs. The King Co/Eastside TRS systems work awesome! Pulling in full signal. All VHF?UHF stuff works well also. Still have the main issue with SNO TRS. Its driving me crazy......

800MHz can be very spotty. Remember, the wavelength is only about 13 inches, so you will get peaks and nulls about every 3-1/4 inches.

Try this:
Put an antenna right on the scanner and tune it to the control channel. Then slowly move the scanner around (around the house, not in circles) until you hear the control channel.
That will show you that your location might be the problem.
