[Alinco] Alinco DJ 580 T UHF receive problem

[KC4QLP@aol.com]

I have an Alinco DJ 580 T that has very poor receive sensitivity on UHF only. 
The VHF works fine.
The UHF sensitivity is so poor that another radio running a half a watt held 
at arms length from the Alinco 580,will barely pick up the signal. I have 
another Alinco 580 that is a parts only radio..so finding parts isnt a 
problem. What I need to know is what parts on the board make up the UHF 
receiver..I have no schematic here.

Anyone can shead any light on this would be greatly appreciated.
