Just to be clear, we are not talking about the GRE Digital hum right?
First - thank you everyone - I think this idea of online scanner feeds is long overdue and I really want to do my part
I'm a news reporter who has been listening to a scanner 24/7 for 35 years - but NOT a techie at all.
I am not sure what you mean by a GRE digital hum.
Bearcat BC350A Scanner sounds fine until hook up wire to computer.
Listening to it on the feed thru radioreference website the hum is not real bad - but its there - listen to feed in extreme northern Michigan Upper peninsula) Marquette County.
However - now I have to listen to scanner off my computer speakers - and the hum is awful.
I have tried living with it - but it's crazy awful and I have to listen to scanner for my job.
Again - hum happens no matter what computer/speakers I use (have tried on three computers in two different rooms.
I have also moved scanner into several rooms without other electronics like kitchen.
Ground loop isolator did virtually nothing to stop hum.
I will try the 3 to 2 prong adapters - will likely need about 8 of them as I have two strips with about six things plugged in - printer, two computers, modems for internet/TV/phone from same cable company.
Plus router (all 3 computers off same router).
One suggestion was running second wire from ground on my computer to ground in scanner.
But I am not sure where the ground is in my scanner and am afraid to do something I do not understand for fear of screwing up scanner and/or electrical shock.
My ground loop isolator has RCA and 1/8 inch adapters.
Unplugging channel one (red plug) RCA doesn't eliminate hum.
Unplugging channel two (white plug) RCA stops feed.
Because of that - the guy at Radio Shack - said the mono cable adapter wouldn't help.
(I don't know cause I am not techie - I just took his advice)
Ref. suggestions - thank you everyone - I will try all that are possible.
One other problem - I have spend about $30 on this so far - and while I think this scanner feed from across U.S. is a very needed and cool idea - I am a local news reporter who doesn't make a lot of money and budget is already tight.
Anyone who has spare parts they may think work I'd be happy to provide my address.
I stay up late and get up early - phone is

I live in extreme northern Michigan.
Later this week I will be out of town (Arizona) for about a week.
