DVM Modem Compatibility Matrix

[majmongoose]

It is time to add a compatibility matrix for the project. Below is a sample of a table we could use. Please provide any available information about your known working setups, so we can add them.

Manufacturer	Model	Repeater/Mobiles	Modes Tested	Modem Type	Notes
Motorola	CDM750/1250/1550	Mobiles	P25	DVM-V1	Two mobiles connected via rear connector
Motorola	MTR2000	Repeater	P25	STM32_MTR2k	requires detuning for deviation
Kenwood	TKR-850	Repeater	P25	STM32_DVM_USB	use WIDE and detune for deviation

Manufacturer	Model	Repeater/Mobiles	Modes Tested	Modem Type	Notes
Motorola	GR1225	Repeater	DMR, P25	RB-STM32 and older Arduino Due ZUM based Modem	Connected via rear 16-pin connector
Motorola	MTR2000	Repeater	DMR, P25	RB-STM32 and DVM-V1	Requires detuning for deviation. Connected via available pins on the J5 system connector. For DMR requires setting the DMR Rx Delay in config.yml to 160.

Manufacturer	Model	Repeater/Mobiles	Modes Tested	Modem Type	Notes
Icom	FR6000	Repeater	P25	RB-STM32-USB	NOT COMPATIBLE – RX Disc Audio works fine, but digitized audio path for TX External MOD input on BOTH DATA and Mod IN via rear ACC DB25. Tried injecting TX audio into the VCO chain via C176 / R127 but filtering found downstream inside the sealed VCO can preventing data being transmitted properly. Not worth it (difficult SMD soldering)
