<DIV><FONT size=2 face=Arial>Today I had some time to work on a MFJ-1278
Revision 9 PCB. I just happened to have one in storage and confirmed it was a
Rev 9 PCB. There is a slight difference between the Rev 8 and the Rev 9 PCB.
The Rev 9 PCB has the FAX/SSTV option card installed and the Rev 8 PCB I
modified years ago did not. This explains why so many have failed attempting
to get a Rev 9 PCB working with UIDIGI. The Rev 8 modification stands with the
exception that you must remove IC's U303 and U304 from the FAX/SSTV Modem
board to get it going. Actually, you can simply remove the FAX/SSTV Modem
board completely to reduce power consumption if you wish.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I followed my own modification instructions from
the MFJ-1278 Rev 8 PCB that was posted to make sure I did not miss anything.
It did not work at first until I realized the Rev 9 PCB had the additional
FAX/SSTV Modem board installed causing problems on the data bus with UIDIGI.
So, I simply removed U303 and U304. I bent the tabs on the FAX/SSTV board to
slide it off the side in order to install the custom wired header at U28. When
you do this you can remove U303 and U304 before you slide the board back onto
the mounting tabs. When I get a chance I will post some pictures of the
MFJ-1278 Rev 9 PCB. It receives, decodes, and transmits perfectly with UIDIGI
1.9 beta 3 firmware.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I just uploaded a document to the UIDIGI Yahoo
Group outlining the modification required to make a MFJ-1278 (Rev 9 PCB) work
with UIDIGI. It has been working on my bench all afternoon and headed for full
time service this weekend.</FONT></DIV>
