Ottawa Airport Authority

[DaveH]

Software showed Cap+ so that is why I included that. If something makes it not software is making assumptions am I correct? I also logged Airport Authority tags on that frequency which is why I included it as part of the "system." Thanks again for the feedback.

The Air Canada frequencies are not Cap+. Possible explanation is in DSD+ Event window if
you were monitoring a Cap+ system then switch frequencies to conventional, the Cap+ may
still be displayed at the bottom; check that. If in doubt, clear the system line, may need to
exit/restart DSD+.

If you are seeing Airport TGs 11, 21....etc on the Air Canada frequencies that is interesting but
also worth checking, using RIDs. Airport radios might be able to operate on Air Canada frequencies
but does not mean they are the same system.

As mentioned earlier, TG numbers can be the same in different systems but be unrelated. In my
logs I find several TG 1000's etc. on different systems.

Thanks for the tip with DSD+. I'll make sure for each new system or frequency to reopen DSD+, that probably is what occurred.
A clarification on my earlier post about hearing Authority TGs on the frequencies. I didn't hear or see them on the Air Canada ones, just the frequencies I listed to indicate that they are related in some fashion.

Sooo... Do we have enough info between frequencies and talkgroups and system type here yet for submission to the database for the Ottawa Airport Authority?

Questions to answer:

(1) Are correct system frequencies known, excluding extraneous ones from other systems?

(2) Are correct channel numbers for each frequency known?

This system at the airport seems to be correct. I have the site set up for DSD and it is voice following fine.:
Cap+, 6015, 2, 1, 461.4125, 0.0, 0
Cap+, 6015, 2, 3, 463.0125, 0.0, 0

The active key 'D" will discard current current system information.
Should save you having to do a DSD restart.

In DSDPlus 1.101, pressing F in the Event window "forgets" system info which clears that line. Otherwise,
Cap+ stays on the line even after switching to conventional DMR. This situation can be very confusing on
a shared channel with both Cap+ and conventional, and sometimes you can't clear the info fast enough
as it flips back and forth. Closing/restarting admittedly is a bit extreme but demonstrates the issue.

Sorry, I guess I should have mentioned that my Active Keys List is from DSD+ 2.242

I went to the CYOW plane watching lot with my DSD+ full version and knowledge of how to use it last week.
I can confirm that:

Airport Authority System:
Neighbor is Site 1
461.4125 is Cap+ Site 2 DCC=2 This told me it is First Cap+ Repeater (Ch1 and Ch2)
463.0125 is Cap+ Site 2 DCC=2 This told me it is Second Cap+ Repeater (Ch3 and Ch4)
TG=51
This site on this system looks submit-able.

Neighbor is Site 2 - looks like it needs another frequency as it is one of the repeaters.
460.2125 is Cap+ Site 1 DCC=1
TG 51

Air Canada
Site 1
460.7000 is DMR BS DCC=8 - I need more details to confirm the rest of the frequencies for the system.
I will be going back this week or next to confirm the rest of this. I will also attach my raw data for those interested in looking at it in an up coming post.
