Hum when receiving carrier

Posted by Lewis L on 07/02/2009 16:26

I am restoring a Hallicrafters S-77A boatanchor. It works great, but when receiving a station, there is hum, but with no signal there are just few pops and crackles. I know about this, but for the time being the hard drive between my ears is not finding it. What is the name of this phenominum??? Thanx, Lewis
