[Boatanchors] HQ-180 dial window discoloration

[Al Parker]

Good AM Gary,
	It's all explained in one word, FTFM.  ;-)
	The manual for the HQ-180 series takes several pages to show in detail 
the steps required.  It's really not hard, but there are a lot of 
spacers, etc., that need to go back in in the right places.  I've done 
it a number of times.
	If you don't have a manual, it's available on BAMA/edebris.  If it's in 
djvu format you can download the reader for it from there.  If that 
fails, let me know and I'll email it to you.
73,

Al, W8UT

The receiver may have been in a location where it was exposed to direct sunlight for a considerable amount of time.  If my assumption is correct, there is nothing that can be done to restore the clarity of the window material.  The use of any abrasive material would assume the damage was restricted to surface level and would result in the removal of the black index line.
