DSDPlus FMPx .bat file supporting multiple control channels

[W4KRR]

I'm trying to create a .bat file that has multiple control channels, in the event that the control channel changes, or it has changed since the last time I launched the program. I.E., it should try the first channel listed, and if that isn't the control channel, it should move on to the next one in the list. Is this possible?

I have tried the below .bat file, but it doesn't work:

start FMPA -i1 -rc -o20003 -f935.4625 -f935.4875 -f937.8875 -f937.9125 -f938.175 -f938.500 -f939.400 -_1 -wsl15.43
start DSDPlus -i20003 -rc -O NUL -wes400.800
start FMPA -i2 -rv -o20002 -wsl240.43
start DSDPlus -rv -i20002 -O NUL -wes400.800

If it’s a p25 system you don’t need to. P25 gives a band plan, it will know what frequencies to scan through. Put the current cc and the system will scan for it if/when it changes

It's not the band plan that comes into play with that, but rather the other frequencies that are flagged as control-capable. The site should be broadcasting those alternate control channels a few times per second, and so if a control channel rolls, DSD+ would have already written those alternate control frequencies to DSDPlus.P25data, and would start to search those as long as Hunt for Lost Control Channels is enabled.

Your idea is making the wrong program try to solve the problem. DSD+ does the thinking, it just points FMPx to where it thinks the C/C should be. The first -f will give it a starting point, any successive ones will just reset the "initial frequency" to the next subsequent value that's passed by subsequent-f



as you can see I passed it two initial frequencies, and it just kept resetting the initial one. There clearly isn't a sanity check in the program that prevents it from trying to repetitively set an initial freq more than once, and obviously no error message associated with it. As @GTR8000 pointed out, the listing of alternates in DSDPlus.P25data, makes DSD+ do what you thought FMPx should be doing.

The particular system in my example is a Harris P25 system. I checked my DSDPlus.P25data file, and all frequencies are listed, and all are listed as being control channel capable. I also have "Hunt for Lost Control Channels" checked, but it doesn't search for any frequencies. I have to manually enter the correct control channel in FMPx.

I knew it was written to the p25data file, just didn't realize dsd figured that out and it wasn't the bandplan that "helped" with that.

Manually tune to the current control channel, then in the CC instance of DSD+, Control menu / Startup Options / Load Current Trunking System.

Done.

Thanks sw, I will try this.

Tried this; it will not allow me to select "Load Current Trunking System". It's either grayed out, or it just moves to the selection under it.

As soon as I start monitoring a trunking system in CC mode or Combined CC/VC mode it un-grays for me.

I'm going to have to play around with this. I'm not sure what is meant by "Current Trunking System" and "Specified Trunking System". How do you specify a trunking system?

The one that you're monitoring when you click on "Current Trunking System".

and "Specified Trunking System". How do you specify a trunking system?

You click on the protocol (like P25), then enter the network ID and site number.
