Just want to confirm that the submissions you sent in, you already "translated" them all from the 0-15 numbering to the 1-16, correct? They all start at 1 so I'm sure that's the case, but I also know better than to assume anything. ;)
yes i did

That’s fine. Keep your secrets 😂
Perhaps I misunderstood your initial post. What exactly are you looking to do? To capture a system's band plan with software so we can include it in the database? I interpreted your post to be asking what you can do with the band plans once you have them.

The former. To capture a system's band plan with software so we can include it in the database. I haven't dabbled in it much as I tend to get carried away, so I've put it off. I play with SDRTrunk and have a script that pulls my agencies' unit IDs so I can see whos on and what talkgroup they are parked on. I'm not computer illiterate; I just haven't applied myself in this direction yet. I'd rather get a good start from you folks that have been doing it rather than waste my time stumbling through it myself.

If you're running SDRTrunk, simply click on the control channel row in the Now Playing section, then look at the data presented in the Details tab below that. The band plan will be among those details. You can copy/paste everything in that section and submit it, I'll get the data updated. Thanks!

For some reason, with Sdrtrunk beta 2 & 3 on Windows 10, when you select text in the details area, the right click, copy, does not work. Control + c will do the copy. Just throwing it out there for @N2YQT

Wow... that's super easy. Thanks!

Question. Very interesting. Just what is the significance of this information for us “end users?” I just read through the wiki on this a couple times. So for example, the Albany Metro band plan shows six unfamiliar frequencies. Should these be part of someone’s programming for any system?

Just trying to understand things better. Thanks!

As GTR8000 mentioned in an earlier post, the bandplan is required only in programming a 2-way radio and scanners do not need it. The bandplan is what allows the radio to decode the CC channel data by use of a base frequency, step and offset associated with the first digit of the LCN. It also shows which LCNs are TDMA or FDMA. Scanners generally have this capability in their firmware. Professional radios use their system specific bandplan programmed for security and reliability.

None. This info is only significant for those trying to program radios on trunked systems they do not belong on.
