[HBQRP] Cool website - DDS VFO with Ardruino and 40 meter rig.

[Arnie Grubbs]

Hi Group,

Well, here we go again. I found another web site with some interesting
DDS and builder info...

http://www.theladderline.com


You might have to click around a bit on the site to see it all, but the site
shows using a DDS-60 from AmQRP group with an Ardruino for the controler.
Then this is used as a VFO signal source for a 40M CW rig.

Kind of interesting.  The DDS-60 has been around for a while and will
go to a higher freq output than the "China" DDS's that I mentioned in my other
earlier e-mails.   This is because it uses a AD9851 instead of the AD9850.
The AmQRP group also developed the NEU-PSK  modem, and the 
DSP cube radio.

I hope you find the pages interesting.
