A bit of a long post so hopefully you stick around.
I've been playing some more with the trunking capability of my custom DSD on a TIII DMR (MOT - CAP MAX) network.
I'm currently using a base frequency to work out the absolute frequency of a LCN when I need to switch frequency to follow a call.
On the network/site I'm working with, I've noticed an odd thing with using this approach, read on.
This is a TIII 'Huge' statewide network (many sites) and also has LCNs that are spread out over approx. 25MHz (485-510).
On the site I'm working with, it broadcasts the adjacent sites. One of these adjacent sites does not appear on the frequency where it's expected using the base frequency.
This base frequency I'm using works fine for finding the all other adjacent sites (and the traffic LCNs when on them).
I have verified this odd sites real frequency and Network ID/SiteID and determined the base frequency it should be using to follow traffic on it.
The question is:
How would a real radio switch to this site if needed?
When a real radio is programmed for use on one of these trunked networks, does it:
Just use a base frequency with a list of CC sites and it does the calculation to find an adjacent site (which wouldn't work it seems in the above case).
Or does the radio have a list of all CC sites in the network with the absolute frequency and a base frequency to use so it can look it up when needed.
Or does the radio have a list of all CC sites and traffic channels in the network with the absolute frequency it can look it up when needed.
Or none of the above. What way does the radio do it?
Still here, thanks for listening.
