DSD+ FL questions

[sonm10]

How do I force DSD+ FL to not correct frequency. I have two different P25 sites with frequencies very close to each other. CC 857.2375 and CC 857.2625. Im trying a listen to the one farther away which obviously has lower rf strength. I have upped the gain - LNA 15, Mixer 15, and the third one is 10. I can get it to decode, but DSD keeps correcting the frequency to the one with more signal strength. FYI, the one with more strength is in another county.

I have a lot of radios that register without a tgid, what does this mean?
Affiliation request target radio and source radio, what does this mean?
Whats the difference between affiliations and registrations?
When monitoring large statewide systems, are there a lot of tgids out there with affiliations only but without voice traffic. Just slightly curious.
Does anybody find any advantage to monitoring affiliations vs not?

Any way to enlarge the individual windows, have to decrease text size to see it all.

Sounds like you're using FMPA. I'd use a narrower bandwidth and I'd adjust the PPM correction value in FMPA if the Airspy is off-frequency at all.

Registration isn't an affiliation, so there is no talkgroup involved. Registration may involve some sort of authentication to block cloners/outsiders.

Affiliation request target radio and source radio, what does this mean?

It means the system is asking the radio if it's still out there.

Whats the difference between affiliations and registrations?

An affiliation tells the system which talkgroup the site has to carry so the affiliating radio can hear it.

It happens. There can be radios sitting on standby talkgroups, whatever.

Does anybody find any advantage to monitoring affiliations vs not?

Yes.

Drag the double-triangle box that shows up in the lower right corner when you hover over it.

Gtr8000 mentioned that a while ago if the source is SYSTEM, but it's two different radios and usually have goofball rids
