Amateur Television (ATV)
In mid-2015, MDARC converted the downlink transmitter of its ATV system to be fully digital. We are now able to transmit multiple channels of HD quality content in the same bandwidth that the old analog transmitter required. This also means that a digital receiver is needed to receive the MDARC ATV signal. Analog reception is no longer operational. Our uplink receiver can now handle both analog and digital, however. So if you are transmitting into our system in analog, your existing analog equipment will still work.
Check into the ATV net on Thursday @ 20:00 hours local on W6CX 147.06 MHz + 100 PL repeater.
MDARC's digital ATV (DATV) repeater transmits on 1244.5 MHz.
