[Pafgbt] BYU receiver downconverter problems

[Jay Brady]

Bill -

I have looked all over for any spare parts we have the may
 help you. I've attached a spreadsheet with a list of the parts I've 
found. Many of the parts are still in the original packaging, but there 
are a few parts that I could only find soldered onto PCBs (test boards 
or earlier revisions).

Subject: [Pafgbt] BYU receiver downconverter problems









While troubleshooting we have discovered some problems in several channels of the BYU receiver/Downconverters. 

 

 
Does BYU have more information on these PCBs, like detailed schematic and BoM.  Also, when were they made and how were they tested?  We will probably be going through all the cards, and likely have to replace components in some cases.
