IdleMonitor said:That one has also been up and down lately also, but if Matt chimes in here on the thread, I'm sure he can answer to that one though.
Chrome69 said:Hi Matt , your feed has the hum to it think you will need to address the issue... Nice to see it back up again... When i used the 785 i had the hum on my feed but when i switched to a 330T the hum went away.....
ve3nsv said:Are you using Mic or Line in? You could always turn the Line in level down in the record properties and turn the scanner volume up, might reduce the hum.
mbstone99 said:I am using a Rat Shack 2051 fed into a SB16 in RedHat Linux box using the line in. I turned down the line level a bit and pumped up the volume on the scanner a tad. The one thing that really still annoys me is all that static on certain frequencies.
jellotor said:Matt, do a google search for ground loops. That may be part of your problem. Back when I had to worry about such things, ground loops caused lots of problems between two sets of audio equipment...for example a TV mobile and an in-house PA system. A solution I found was to drop the ground on one of the audio devices or to place in-line an old Shure mixer with the ground pin busted off. Eliminating the ground connection between the two sides eliminated the hum.
Could be a similar problem with your setup. The chassis of your scanner and your computer should be grounded, so you may be able to lift the ground.
jellotor said:Actually what he needs to do is eliminate the ground loop. Here's a bit of info from my ground loop bible, the Rane AVA22d Audio/Video Delay Alignment manual...
"Each component of a sound system produces its own ground internally. This ground is usually called the audio SIGNAL ground. Connecting devices together with the interconnecting cables can tie the signal grounds of the two units together in one place through the conductors in the cable."
I would suggest trying first a mono cable (ie standard mono mini plug) to see if the problem is related to a third conductor in the cable tying the chassis grounds between the computer & scanner together. If a mono cable works, chances are it was a ground loop.
If the hum is still there, check for interference and possibly upgrade to a higher standard of cable, one that is better shielded. Also, check the cable run for any potential interference from crossing AC lines. It's kind of a long shot, but check nonetheless.
Without seeing Matt's setup I would stake my reputation on the problem either being a faulty/intermittent connector, ground loop problem/mismatched cable or combination of the two.
Chrome, the audio out is grounded no matter what...without a ground you won't get a signal as the circuit isn't complete. The difference with a handheld is that the case isn't made of metal which means the 'ground' isn't really a chassis ground, per se. For example, a discriminator tap would have to be grounded to the same spot as the headphone jack is. And having cracked open a BC250D only once or twice, I have no idea where that would be. However, electrically and functionally, a base/mobile and handheld are identical in the need for a ground.
