Hi Pete, Why not... the ID'er looks pretty easy to construct if anyone ever wanted to build one from scratch (for fun and to use) we now have most of the required information.
The guys have been corresponding with me direct and they've sent the original ID chip to me for free reprogramming. I can probably do that part by hand. I have received diagrams and some of the manual for the original GLB Unit (IDer). I'll read the chip and send you the bin/hex file and the circuit information. Have a look and if it's worth it we can make up an IDer as possible project. cheers, skipp > n2...@... wrote: > > If there is any interest in this still, I'd be willing to look at > writing some type of simple prg. to read and generate the binary > image for the 2716 file.. > > I have some other program's that use a similar look up table > technique, so it should be pretty simple.. > > Pete, N2MCI > --- In Repeater-Builder@yahoogroups.com, Mike Morris WA6ILQ <wa6ilq@> wrote: > > > > At 12:47 PM 01/29/10, you wrote: > > >Can anyone burn a 2716 Prom chip for a GLB ID-1 Ide'er? > > > > > >Not a standard hex file. have some docs. > > > > > >Thanks > > > > > >Fred > > >wa2cam@ > > > > Actually it's is a standard hex file.
