Using a DDS card to Drive the SoftRock-40


Marsh Parker
 

I read Bill, KD5TFD'S comments in the AMQRP Future directions. I
wanted to do something similar. Be careful of the reference
designators! They are from a previous version of the PCB/schematic
and some have changed. His R18 (from version 3.1) is now R2 which is
the LED current limiting resistor. I left it in. I put my 12v input
header in place of R1. C2 is shorted to gnd. R1 is the same, but
replaced by the input voltage header.. C8 is the same. His R2 is now
R3, 5volts to Q2.

I haven't finished my soft rock yet. Spent too much time on my L1 gnd
short.
