Circuit diagram of TRX2A Main Board Rev. C?

[DG4FCO]

Hello,

I wonder where the circuit diagram of the main board Rev. C is?
http://www.jumaradio.com/juma-trx2/manu ... V2.6.5.pdf only contain diagram for Rev. B. As there are a few (minor?) differences between the two revisions I like to get the right one
Can anybody give a hint/link?

Thanks in advane

Hi, Frank,

Attached to this post are the details of the Revision C version of the Main Board. The principle change is the incorporation of the Spur Elimination module rather than having it as a separate attachment as it is in the Revision B version. On the image, you can see this in the top left-hand corner where there are two transistors marked Q1 and Q2.

Also attached is the schematic for this board.

Hope this helps.
