[DSP-10] Lurker now needs help

[Don Jackson (AE5K)]

Thanks Roger for the rapid reply.  I imagine you know how gung-ho I 
am now in getting this DSP-10 on the air ... after planning and 
procrastinating for so long ;-)

Haven't tried anything further on it yet, but will do so in the 
morning.  Hopefully everything will go well...else will be back on 
here if I run into a dead end.  Thanks for the info on your web pages 
too.

I'm also browsing the new Experimental Methods in RF Design book in 
between DSP-10 sessions -- probably the best book the ARRL has 
published in my 50 years as a member.  Cannot wait to try some of the 
ideas presented.  (Of course, have about a dozen other projects 
already in the queue)

73,
Don AE5K
