Of course some are voice frequencies -- we were looking to see if (a) the control channel was present in the set of frequencies programmed and of good quality (we don't know for sure about the latter part of that question) and (b) if voice activity is present such that if the CC was being clearly received and processed properly, think should work correctly (i.e. the site is active).Is it possible some of the site frequencies you programmed in the trunked system are voice frequencies rather than control channels? Any digital transmission on a freq programmed conventional may be received as "static", even if it's a voice transmission. It depends on whether the scanner realizes it's hearing a digital signal and attempts to decode it.
Do you have all the frequencies for each site programmed, or just the control channel? If you only program the control channel, and the site switches the control channel to another frequency, you will lose the ability to monitor that site.
The best way to distinguish control channel and voice data is control channels are broadcast continuously, and voice is only broadcast when a user keys the mic.
...or, just go outside.... it's VHF and - as far as I know, not simulcast.... so it should work fairly well unless you're just too far away or getting some type of interference (which a better antenna will just make worse). Still, some of these STARS sites are hard to receive - particularly at distances... I have the same problem here in NC with some VIPER sites.Makes sense. I'll move to a different antenna at this point. Thanks again!
So -- what was different about how you programmed the system this time as a trunked system vs. the first time? Did you use different software? Software vs. manual programming?I reloaded the VSP sites and groups as a P25 Trunked System instead of conventional, and VA STARS seems to be working now. I'll test if for a while, but I think the fix was adding the APCO BAND PLAN frequencies under each P25 site. Thanks again for your help.
I've seen other similar issues reported by users of FreeScan... guess that is why it is free.Yeah, I used Proscan to import the data from RadioReference instead of FreeSCAN, and the System was imported as P25 instead of MOT2, so there was no need for me to change this manually this time. The only real difference that I noticed between my config and the .996 file uploaded by WMBIO was the APCO BAND PLAN frequencies, so I added those frequencies. I guess STARS doesn't work without them? If that's the case, I wish they were imported automaticallly along with the System. I'm getting countless voice transmissions today and with very clear/strong reception. Thanks again for your help.
