That's the noise but through my small amplified 2.1 sub and satelites of course a little more accentuated. The noise also shows behind a vented lazer heater and behind my couch consistantly for a couple of seconds but basicaly a very acceptable broadcast most of the time. Also if i stand between the loco and my stereo[signal interference?] there is the noise.
Now this AM very little if any noise from wheels but i also went 88.1 to 106.7 last night. It seems the freq with some weak station broadcast do better than the no audible broadcast frequencies.I am still unshielded and no res or cap at t
he speaker terminals but i did leave the .01uf caps across the motors. Also the batteries are 1.2v ni-mh and have at least 10 hrs on them.
this listening experience has steered me away from my 3 inch only speaker days..and i have 4 PS2 just "jonesin" to be converted.
