I'm sorry to resurrect such an old thread, but I need to know whether it is possible to program a Quansheng TG-K4AT to have a 6.25 KHz step. I just bought one and noticed that it has 5 KHz and 12.5 KHz steps, but not 6.25
I also need to know what software I can use to program the device.
Thanks in advance.
