QRP Computing

Problemchild

5 Jun 2013

With the Raspberry Pi and other SBCs been used to drive SDR radios of all varieties it's interesting to see that

this computing has also been used for  QRP (Low power) Ham Radio.

 

http://www.users.on.net/~davroz/vk6di/argocaptures/argo.jpg

 

A rather interesting mailing list has popped up with  Specifically for QRP and Computing.

As you'd expect the bias is towards constructing and using your own equipment so has a nice

home brew feel about it ....If you have even a passing interest to computing & Radio try it out

    Looks like a frequency occupancy vs time diagram. Am I wrong?

    Yes it is ...Commonly referred to as a waterfall diagram. These signals are very low power and close together thus the interest in communicating this way!

     

    The signals them selves are often smaller than the ambient noise.
