[Boatanchors] Motorols Micom-s

[Ispoulin--- via Boatanchors]

I'm attempting  to modify a Motorola MICOM -S Land Mobile SSB  Radio,Model 
D80JMA1N00AK, that is configured with Upper Sideband to  Lower Sideband. The 
manual shows an optional LSB Board ; PN;TRN4961A which plugs  in to the 
main circuit board. It has a 11.4 Mhz crystal filter for LSB. I would  like to 
find this board or a parts radio if anyone has something to help.  Thanks;
