SDS100 Is there a limit? Max number of frequencies in a single favorite list

[thevig]

In a conventional FLQK, what's the most frequencies you've programmed in one?

I don’t use QK’s. But how do QK’s enter into how many conventional frequency’s/channels can be in a FL?

Let me try to word it another way. Think about it like banks in a non trunking scanner. As inefficient as it might be, anyone ever program, say 3000 channels/frequencies in a single list?

 

[n1chu]

Yes, again, what has that to do with QK’s?
As for how many channels, I wouldn’t worry about that. If you ever maxed out the available space you’d probably never get back to the beginning of your FL. But a scanner can use a couple types is memory. I believe Uniden calls the type of memory they use in the BCD325P2 and the BCD996P2 Dynamic Memory and the memory used in the BCDx36HP and the SDS series is another kind. Uniden has their own name of it but I don’t remember it. Both can be researched with a google search. Start with Radioreference and scanner memory.

Why would you want 3000 frequencies in a FLQK that makes the scanner take 30 seconds to make a complete pass?

Pretty sure a FL is size limited to 1mb. How that translates into number of frequencies i don't know.

It's about 7kB for each 100th of analog conventional channels
1000 ch are 70kB
10,000 ch are 700kB
15,000 ch are 1MB and takes 2,5 minutes to scan at a rate of 100ch/S but probably 50ch/S are more realistic.

One could be using it mobile with GPS, one coul have multiple QK that let yu select sites, agencies, counties.
That's how I do it. I have one with 4000+ TGID, 1500 freqs. and 1000 Unit ID. Normal scanning is 200 TG or so.

One of my Fav. that I only use mobile has 3100 Freqs and 2000 tg. Mix of conventional and trunk. I use this mobile, mainly with a HP1 and GPS.

Does the number of talk-groups slow the scan down on the SDS series?

 

[buddrousa]

Not that I know of just number of sites.
Like stated above using a gps would work but those numbers without filtering you could miss a large amount of traffic

That's what I was thinking but didn't know for sure. Michigan has an insane amount of TG's! I don't program them all but a fairly large number. Some are not real active but they're ones I don't want to miss when they are active.

I have one favorites list that covers eastern Wisconsin, northern Illinois and Indiana and southern Michigan. I then use GPS and don't touch my radio from home to Detroit. Works awesome. Drawback is if anything changes on the route I'm screwed and have to either update it or start over from scratch. So in the future I may just scan the database. It was fun setting up rectangles and circles, though. Fun meaning tediuos.

I'd have to look, but it's got an awful lot of conventional and a ton of trunked systems in it.

Conventional: No, Trunked: Yes (200 sites times 5 frequencies per site and then a boatload of talkgroups plus lots of Radio IDs).

Favorites Lists grew in size/capacity because of statewide trunked systems. Quick Keys are a means to turn on/off Favorites Lists. Favorites Lists are limited in size to 1 MB, whether they are conventional, trunked or a combination of systems. Each conventional frequency takes up about 100 Bytes, so the engineers built the scanner to accommodate 10,000 frequencies (in theory).

Location Controlled (GPS) scanning could mean just a handful of frequencies are "active" of that 3,000 conceptual Favorites List so it might be very efficient if set up correctly. And then you also have Service Types that can be chosen/filtered.
