Sacramento Fire Tac Channels Not Working?

[DARTSac]

DARTSac, listening to your feed, there seems to be a lot hum and/or background noise. Is this from your new SDS200 or the Barix? So how’s the Uniden doing on the problems of simulcast ?

How are you listening? Crystal clear audio from the 200 to the Barix and to Broadcastify, no noticeable hum. We are monitoring the main site on the system and no issues that we’ve found.

Sounds great to me. Not a bad delay too.

I most certainly understand the tech skills issue, I was in the same boat when I started playing with SDR's. It took a lot of trial and error on my first setup but I eventually figured it out, I do still run into problems from time to time.

As for the dongles, I run 4 on my setups but the actual number you will need depends on the amount of frequency spectrum you need to cover and the number of channels (talkgroups) you want to receive at the same time.

The SRRCS uses ~3MHz of spectrum (851.0-854.0) and each of the RTL SDR's will cover ~2.4MHz of spectrum so you would probably be able to get away with two or maybe 3 if you want to have some wiggle room. The number of talkgroups you will receive per dongle is somewhat dependant on how powerful your computer is. The more talkgroups you can spread between the dongles the better it will work. If you only want to receive a small handful of talkgroups you could probably do it with 2 dongles minimum.

@scannerboy02 Just wondering if I run more than one will I need to buy the kit for each one like this Amazon.com: RTL-SDR Blog V3 R820T2 RTL2832U 1PPM TCXO HF Bias Tee SMA Software Defined Radio with Dipole Antenna Kit: Electronics Or would one kit work and then I can add single dongles to it like this Amazon.com: RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio (Dongle Only): Computers & Accessories

Reception is great now on Broadcastify, must have been a one time fluke. Thanks for providing the service.
