The old 600 series both mobile and base station variants. Manchester bus had a load of them, they were the ones using 107 and 140 MHz, had extra boxes on them for selcall DZVEI if the memory is correct, twin antenna systems on the top of double deckers.
PTT over cellular
Yes already starting to see them and have a system or two in, with a handset which is both WIFI and GSM. There have been the wifi ones out for a while from the likes of icom and others. Motorola Wave. and tait using both IOS and Android apps. Everything is going server based generally hosted by others such as Amazon and the likes.
I am trying to learn Linux server stuff, scripting and all the rest but think I am to old for it to stick in the head. I have been trying for years now, some basic stuff I can do but most of it i need books and days to do, bit like the GPS stuff, tring to get it to run as a service rather than manually execute is starting to be an argument between me and tech help..
I think tomorrow is back in the garage work with my hands.
Earliest radios I worked on where Pye Rangers, and Vangards and W30 am radios
