Re: Freq Shifter : f orget the lower freq, how about external input!

-This sounds like a great idea...and you're the one to try it (on 
your module)!

No, but seriously, folks...every critical component on his board 
are socket mounted.  If something blows up, it's surely going to 
be an IC first, so you could get a couple of what they call 'Surf 
boards", which are these little in-line connectors that have 
solderable leads to them and on the other side, IC spaced pins 
just for imserting into IC sockets.

Do a search on 'surfboard' and add the word "DIP" and you'll find 
them.

with the module in a reasonably 'non-invasive' way. The outputs 
from the quad osc are passed through a pair of jumpers to get to 
the 1496's. Thus it would be a simple matter to pop the 382 chip 
out and with a few other bits to replicate the osc on a breadboard 
and then finally feed the sin and cos outputs back in to the 
1496's. The jumpers are also the correct side of the AC coupling 
capacitors, so without much difficulty one could play around with 
some component values around the osc (and the coupling 
capacitors) to see how it behaves with the whole caboodle 
slowed down. Reckon I'll give this a go over the weekend, just to 
see what might be possible...
