this is for people who know a lot more about MotoTrbo Capacity+ trunking than I do (and trust me, I don't know much)
This post revolves around 2 different SpaceX CAP+ "systems" at Cape Canaveral. Their UHF and 900Mhz systems:
Space X 900Mhz CAP+: https://www.radioreference.com/apps/db/?sid=9558
Space X UHF CAP+: https://www.radioreference.com/apps/db/?sid=10888
Yes, systems is in quotes... here's why.
Myself a couple of other locals have been playing hell trying to figure out "Site 6" on the 900Mhz trunk. 2 of the 4 frequencies assigned by the FCC to Site 6 are actually used at Site 4 (937.1625 and 938.1375). The other two freqs (936.15 and 936.4125) have never been monitored.
So today, I spent some time trying to get DSD+ set up to trunk-track this UHF Space X DMR system. Turns out the RR db was missing a freq and the LCN order wasn't quite right. That has been corrected.
Now here is the interesting part. above I stated that the 900MHz "Site 6" has never been monitored. I think the reason why - is kinda simple - i think the UHF site 6 is part of the larger "Space X 900mhz CAP+ System".... the UHF Site 6 reports site neighbors of 1, 2, 3, and 4. And conversely, (for example) Site 1 of the 900 system reports neighbors of 2, 3, 4, and 6. .... (((there is no "site 5" that we have ever found/monitored))) - so from the Neighbor List perspective, our theory works.....
Where I need an expert here is .... I've never seen a cross-band DMR system before. Is my above theory even plausible or supported by the DMR CAP+ protocol?
>> to have a system site on a different RF band completely << ?
So I need some help figuring this out... once I understand if my theory is possible it leads me to some other questions...especially since there are no dual-band MotoTrbo radios that I know of....
how would a UHF radio on the system communicate with a 900 radio on the system? (would the system simul-key a UHF and 900 repeater?) - this would apply backwards as well - can a 900 radio talk to a uhf radio?
if the above is not possible, what is the advantage of the apparent incorporation of the UHF site into the 900 mhz system?
TIA
