Save your time and get yourself a URM-25D signal generator.  It is perfect
for Hallicrafters equipment and basically all receiver equipment of that
era.  It goes from 30khz to 50mhz.  A Navy piece of equipment.  There is an
outfit in California that upgrades and aligns these units and they sell for
I believe $ 125.00

Hi All,

I have scoured the Internet and noticed that modern signal generators are
extremely pricey. I have also noticed that most of them are not designed
specifically for shortwave use. So I am wondering if it would be benefical
start a open source project to build a modern RF signal generator that is
affordable and specifically designed for SW use. Anyway, I am thinking this
processor:

would be great for this purpose. Someone has designed a RF signal generator
using this processor you can see their project here:
http://www.inthelight.co.nz/electronics/dds.htm

It is fairly simple although I think it could be better. With a built in
Freq Counter, maybe a 100kc Freq. Sweep with variable speed.

Thoughts...????

Rob
