I think it's a lot easier to do limit searches on a tapped scanner to find missing frequencies and piece together a system. It is difficult and time-consuming, but I think a regular scanner will be faster and easier than trying to search with a dongle. A big problem here in the Tampa area is all the systems are DEAD. There's so little activity that it makes it hard to figure out a system.
This has always been a funny thing about Tampa. It's (supposedly) a major city area, but SMR-type radio systems have always been DEAD. Even back in the LTR days (which are still around, a little bit). Instead of having one nice big busy system, we have a lot of small crappy systems spread all over the place with light usage that makes it hard to figure out the frequencies.
system 1:

system 2:

I have been monitoring both of these Cap+ systems trying to figure them out. I have used my whistler 1080, DMRdecode and DSD+ fastlane.
What I have found is much difficulty figuring out how to program them as a trunked system on my whistler 1080, and what seems to be the systems not using all listed frequencies on the FCC database or here on radioreference.
With system 1, I can only pick up site 2 which is 462.3000 mhz. According to DSD+ it lists this frequency as Channel 1&2, Problem is there are multiple talkgroups active and it seems on my scanner it is not picking up all the slots correctly, I do have it set to receive any slot. The question i have is when i enter in the system should I be entering the trunked system as channel 1 462.3000 and channel 2 462.3000 or just only entering 1 frequency for this system as channel 1?
With system 2 I have been monitoring for several weeks and I only receive voice traffic or data bursts on 452.875, 451.975 ad 452.975. DSD+ is showing the the first frequency as 1&2, the second as 3&4 and the 3rd as 5&6. No matter how I enter the system in the scanner as a trunked system it will not follow correctly. Again am i to duplicate the frequencies when entering them into the scanner? Should I leave the rest of the listed frequencies that seem to be dead with no traffic out?
I know this is a software forum but I was directed here, thank-you for any help.
