I have been looking for G3LDO with 60 seconds dits and nil just more and more interference. Today I did a methodical series of test and I have found that the speaker I have been clip leading into the circuit so I can listen to what is going on, straight noise of course, is in fact reacting to the large blowers I have running in my remote site. The Blowers are the source of interference that has been driving me almost nuts looking for the source. Have any of the others had local speakers become a visible component in their receivning systems? Larry VA3LK
