You make it sound so easy. 1) I write firmware and software at all levels. 2) I have many different scanners, each with it's own methodology of organizing frequencies and channels. 3) I've never used the RR import feature for myself. 4) I do use the RR data when programming my radios.
Each year this process has gotten more complicated but I've used the same method. I maintain everything I want to monitor in a large Excel file. While a radio like the SDS-100/200 can hold it all, most of the others have to be programmed in pieces (such as via Favorites in WIN-500 compatible models). I've got radios that organize by banks, lists and SD card lists. A model like TRX-1 uses a totally different programming scheme than SDS. Heck there's quite a bit of differences between programming a PSR-400 (20 banks) and PSR-500 (20 lists).
What I do is have a "conversion tab" in Excel for each model. And then there's converting conventional and trunked, analog or P25. And just when you think you have it under control along comes a new model with yet another scheme. It's not all bad as these new models bring along capabilities that the models before them didn't have. But to create an application that others would use would take a lot of work and there's simply no ROI (unless someone just does it for fun).
“You make it sound so easy”… No, no one is intentionally trying to say what I suggest would be easy, however, it would be labor intensive. Ubbe’s post was just an example of a rough flow chart… each step would be daunting to say the least. Is it doable? That’s the question I have. RT Systems has programming software for tons of amateur radios, all make and model specific. So there may be hope doing the same for scanners. I’m also NOT saying it would be a profitable venture if developed for profit. I’m only curious about if it is doable.
To that end, I have contacted Butel. Butel markets programming software for scanners which have the ability to do the auto downloads from RR, and it works much the same as Sentinel, for the first part of updating your scanner. I haven’t received a reply from Butel yet… at this point, my guess is Butel will probably tell me it’s not feasible from a cost standpoint but again, I’m only interested in the feasibility of the idea, can it be done regardless of cost? As you say, is it doable from a standpoint of doing it just for the fun of it? Amateur radio hobbyists have created programs of this nature for amateur radio applications and have offerred it up for free or ask for donations to offset labor and materials.
Its an interesting question. One which I hope will stir the creative aspirations of those in the scanning hobby that have the expertise to run with it. I don’t have the skill to do it myself, just wondering if there are those who might consider taking it on, in which case, I hope they start with the SDS100/200 series!
