RDDS boards, etc

Richard <richard@...>
 

Are there any RDDS boards still in existence. ?
I seem to remember John posting the supply was stopping.
If I do put my 3cms in to beacon mode when not in use I will need
another to separate out the LO for that band.

I do already have a few LMX2541 and a PCB for generating the 144.xxx IF
source, IF the phase noise on that device can be kept low enough for me
not to hear it on 2mtrs , I only use 25mW of LF drive to to transverter
