Thank you Lee for bringing up this valuable feature of the Flex and
other SDR equipment. Proper use of compression (or clipping) together
with equalizers and filters makes high power amplifiers unnecessary in
many cases. Try this concept and you'll find that you can manage in DX
pileups with much less of output power. The DSP can make this function
better than those clumsy hard wired processors of the yesteryears.
Since some time already I'm using 10 W only.
Please, don't pollute the scarce nature's resource, the
electromagnetic spectrum. Save and use small and smart power on HF
rather than heat waves on the infrared bands. ;-)

Ahti OH2RZ recently sent a link to an article that looked at the K3 speech
processor.

I found it interesting you need a room full of test equipment to analyze the
K-3's performance. With the Flex radios you need to turn on the bandscope,
and use the recorder.
Here are a couple my blog entries that look at the versatility of the Flex
system

The article on the compander is how the Flex does its processing. The others
do not address the issue directly but show how easy it is to analyze your
signal.
