Frequencies For Cap+

[rkillins]

I'm playing around with a local CAP+ network (Guelph ON CIty Services Trunking - DMR Motorola Capacity Plus Single Site (TRBO)) with DSD+.

I have FMP24-CC, CC, FMP24-VC and VC all running with this system. I've tuned in one of the system frequencies (412.0125) into FMP24, and the spectrum display is active with the distinctive pulsing of the rest channel. CC is decoding the data from the pulse.

In the channel activity window, it is displaying two channel numbers, 1 and 2, with channel 2 being indicated as the REST channel. Am I correct in assuming that the frequency I tuned (412.0125) is the frequency for channel 1 (and - redundant - 2?)? I have edited the frequency file ...

Cap+, 0, 0, 1, 412.0125, 0, 0

I was expecting to see "412.0125" populate the channel activity window next to channel 2 (and 1?), but it hasn't. Should it? Perhaps my assumption of the pulsing signal of my tuned frequency being that of the REST channel is wrong? Or perhaps my understanding of Cap+ systems and DSD+ configuration is askew?

Most of the voice comms I hear and are carried on whatever channel is the rest channel. The rest channel jumps to the other open (slot or "channel"). Normal behaviour. There are other frequencies in the system, but at 5:30am, it's not very active so one frequency can deal with the load among the two slots.

I do question how to handle this system, as to my knowledge, it has no system id or site number. How do I, if even I have to, record this system and site in the respective NETWORKS and SITE files?

Make up a unique number for the System ID, like 3333. Then use it for the System and Site files also.

Read the info on "Cap+ monitoring" in the Notes.txt file. It starts around line 2140. All of the trunking info in the DSD+ data files is keyed by system ID and site number, so you have to make up a system ID and a site number. Use the RR DB page number (8334) as the pseudo system ID. Since it's a standalone site and not part of a network of Cap+ sites, just use site number 1.

Where is the RR DB page number? For the life of me I cannot see one....

Click on a link in a trunking section of a county in the RR database. Look at the URL. It will be a number at the end of the url.

eg h__ps://www.radioreference.com/apps/db/?sid=7760

OK, got it - Thanks.

Just a side note my Opera browser hides the meat of the URL until you highlight it LOL so I thought I was needing a new prescription for my specs

When you go in to the files listed in the notes and add the frequencies and the sites etc, do you have to go back in and delete these changes before trying to monitor another DMR site even if it's not a CAP+ site?

I set up a separate directory for each unique site...

 

[slicerwizard]

Ouch. There must be upwards of a hundred conventional and trunked systems I monitor with DSD+. Not all at the same time or from the same monitoring location, of course. Separate directories would be massively complicated and it would be very cumbersome to switch from monitoring one system to another.

Add system data to the appropriate data files (.networks, .sites, .frequencies and .SiteLoader) and then just press L to open the site loader window and select a system. For trunked sites, DSD+ will find the current control channel and you're off to the races. For a non-digital site, like analog WX or hams, DSD+ even auto switches to analog mode (raw source audio monitoring mode 1). FMP24 even sets the correct channel bandwidth for the system type. Easy peasy, no?

"Easy peasy, no? "

Well, sort of. Not all sites have unique site number. Same goes for Network ID. for a multi-site trunking network, pressing 'L' works fine, but not if you need to monitor some DMR TII or TIII sites (etc) with default ID of '0' or '1'...

I still keep stuff in separate directory, although I am tempted to lob all my data for say, a multi-sited con+ system (what a headache). The 'L' feature is only relatively new and had bugs. Having not used it, does the 'L' function work ok ???

That's what pseudo network IDs are for.

Site loader works for me. What headaches do Con+ systems create?

I have 117 individual sites across 34 different trunking networks of various flavors in the DSD+ sites and siteloader files and as Slicerwizard said it works exactly as advertised, all from one folder.
