[DSP-10] DSP-10 up and running !!!

[David Wrigley]

Hi Hermann,

I have the DSP processor running in audio mode only at the moment, using
signals from my HF rig to feed it and I'm trying to get to grips with the
controls - I have yet to complete the RF PCB.  I too found the DSP mod a
problem - but in my case I believe that it was because I used a leaky
capacitor, because the DC levels were affected and prevented reset under any
conditions.  I haven't had time to figure that out in detail - I removed the
cap and it works OK without the mod.

Without the mod I have absolutely no problem in startup - it works everytime
I plug in the power connector or switch on the power or press the reset
button.

What is the reason for the mod anyway?

I have five more components to assemble to the RF pcb and that will also be
complete

I can't help with the software because in audio (hardware=0) mode - there is
a  restriction in the modes you can operate with.  - just a thought, what is
your setting of hardware=?.


All the best
David Wrigley
