Re: Motorola Quantar & digital modes
Jim, You don't need an AMBE chip (eg. ThumbDV) at the repeater. Most digital modes require a modem that is connected to the discriminator and modulator (flat audio, no pre/de-emphasis) and appropriate software to handle the protocol. The UDRC II was designed to provide the hardware to support software defined modems and PTT -- see https://nw-digital-radio.groups.io/g/udrc/wiki/UDRC%E2%84%A2-For-Simplex-Hotspots-and-Converted-Analog-Repeaters
