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

Does anyone have experience / knowledge of connecting say a Thumb DV or anything digital to a Quantar?  I have recently obtained a UHF Quantar, and was wondering if it is humanly possible to run it both analog (FM) and in digital modes…I know it’s already P25 capable, but thinking more along the lines of D-Star, Fusion, etc., etc.  (whatever the flavor of the month might be!).   Basically, whatever comes in (i.e., analog, Fusion, D-star) goes out.

 

Thanks in advance,
