I own a collection of Midland GXT1000 Radios FCC ID #MMAGXT50. These radios have a proprietary ‘Group Mode’ feature that allows two way communications between radios with the same Group Mode setting. In general, radios in Group Mode behave similar to radios that merely use CTCSS or DCS codes.
I have assumed for some time that this Group Mode is really nothing more than a different way of assigning the various CTS an DCS already built into the radio. However, when I attempted to confirm this I had no success. I tested this by enabling group mode on a transmitting unit and then trying all the different CTCSS and DCS codes on a receiving radio. The receiving radio never broke squelch when any CTSSS or DCS was active.
So what I am trying to figure out is, technically speaking, what specifically is Midland doing to achieve Group Mode behavior? Anyone out there know?
