FMP24 -_1 -rc -i"DVB-T+FM" -o20001 -P61.7 -f770.94375 -g44.5 -b12.5 -wsl80.0

^ this is my FMP24 Control Channel .bat file...currently it is told to go to 770.94375 when it starts up, to find the control channel of the P25 system I'm monitoring, running in 1R mode. (This computer streams 24/7 to broadcastify, and everything is automated to start back up after say, a power outage.)

The problem, is that periodically, this P25 system will change which frequency is the active control channel. This has resulted in the computer streaming silence, because when I went to check FMP24, I found that the active control channel had changed, and FMP24 was now sitting and monitoring a dead frequency until I went ahead and determined the new active frequency and manually tuned to it.

Is there any provision in DSD where upon startup, FMP24 can reference a list of frequencies instead of just a single one? That way after a fresh reboot, if the first freq it checks is dead, it will continue checking each one on the list until it finds the active control channel?

Make sure the Hunt for Lost Control Channel option is enabled in the DSDPlus options. It will then check the DSDPlus.P25data file to see which frequencies are control capable for the site, and will direct FMP24 to tune to those frequencies when a control channel rolls.

DSD+ Control menu / Startup Options / Load Current Trunking System

Done.

Awesome! By chance, can you tell me which setting/text-string does this change/add, and in which file? (So I can understand the "manually changed settings" effect that this has in the DSD+ system files.) Thanks.

DSDPlus settings that are changed in the GUI are now saved in DSDPlus.bin. Command line switches for DSDPlus are largely a thing of the past with Fast Lane.

Does this mean that I need to remove the " -f770.94375 " from my .bat file in order for the "Load Current Trunking System" setting to be effective? A potential conflict I see would be whether or not command line switches will override any settings specified in the GUI.

I'll let others who are better versed in DSDPlus speak to that...I get the updates when they come out, but really haven't run the software in earnest in quite some time. However it is worth keeping in mind that the batch file/command line switches for FMP24 and DSDPlus are mutually exclusive. FMP24 is simply the tuner program. IIRC if you don't specify a frequency or bandwidth in FMP24, the most recent versions of DSDPlus will instruct it what frequency to tune to and what bandwidth to use based on the system/modulation type. I know that when tracking P25 TDMA, the bandwidth will switch on the fly from 9.6 kHz to 12.5 kHz when it tunes to traffic channels.

(waits for @slicerwizard to correct me lol)

I don't think it matters, but I would remove it.
