[R-390] Alignment Problem on R390A?

		Hello All!

	I just recently acquired an R390A produced by Capehart. In trying out the 
receiver I've noticed that when I start tuning towards a strong AM 
signal I start detecting the station's audio anywhere from 8 to 16 kHz 
away from it's center frequency (using either the 4 or 8 kHz filters). 
When I'm almost at the center frequeny of the station the receiver 
sounds like it suddenly "captures" the signal to it's full strength, 
almost like tuning in an FM signal. Is this due to misalignment or 
errors in tracking?
  	I'm new to this reflector, and although I've been in ham radio for 
twenty eight years, I've been one of those dreaded "appliance operators" 
that you've heard so much about. Even though I've been known to 
successfuly recap a radio by the "cap by numbers" method, I am trying to 
learn how to work on and understand the workings of this equipment 
correctly. Be patient with me. I am going to ask a lot of simple 
"electronics 101" questions from time to time, and I  know how 
frustrating that can be for some engineering types out there. Just 
remember, we all have to start somewhere, and I'm willing to learn if 
you're willing to teach.
