Re: Voter Systems


 

Allstar/RTCM deals with audio delays by applying a GPS derived timestamp to every frame of audio samples so the voter can align them.? All the RTCMs in the system have GPS receivers with 1PPS outputs to give near microsecond accuracy on the timestamps.

S/N is measured at the receivers and sent with the audio frames to the voter.

I would think, the biggest issue with digital over internet would be getting your audio delays to line up.?? Although, I could be wrong.?? If its continuous voting S/N, it will cause issues.

Someone educate me, if I am wrong.?? Every mode I have seen digital would not lend itself to S/N voting at the transmitter site. (At least not continuous).

I do appreciate everyone's reply on this thread.??? It gives me a lot of information to research and decide what I would like to do.??? It seems to me going digital would be the best way for the long run as the manufactures are doing more and more digital radios.?? Plus it seems logical to me that what you put down the link is not going to care if it came out of the receiver as analog or another digital mode.??

The mesh option does make me stop and think as we have a solid private mesh around here that I could use.

The Motorola option seems to be one that I could go with too.??? The Motorola Motobridge that Ranger Radio stated that has 8 voting slots is there a device that goes on the receiver site side? ? Can you give me what a good price might be for used and is this still a production item or has it been end of life from Motorola?

If Doug, KD7DK could PM me I would like to speak with you about the PSRG system and its gotcha's or how it works most of the time.

Thanks!
