Try this.
Put the computer and the scanner on the same outlet strip and use an antenna connected to ONLY the scanner.
Put both the scanner and the computer on a non-conductive desk.
Is there still hum?
Disconnect any other connection to the computer or scanner.
OK I will try this - two questions to make sure I understand
.
Question - computer is on table with heavy duty hard plastic top - but does have metal legs.
Is that OK
Or do I need to find a all wood desk.
Second question - you said:
"Disconnect any other connection to the computer or scanner."
Are you talking about speakers? What is considered a connection.
fyi - scanner only has the the plug-in antenna - and power plug - nothing else connected.
I will buy new strip - and test this.
fyi - It appears the feed has that bad hum - I listened to my feed online - not so bad when I had constant talk from NOAA Wx Radio but now that it is scanning with no talk - hum is very noticeable.
again - sorry my questions are so rudimentary.
Now that I connected the earplug jack so audio loop is completed (not muted by jack) - I can listen to it on scanner speaker with no hum.
But that doesn't help online listeners
