[Elecraft] [P3] How to measure bandwidth of RX signal

[Bill Frantz]

For a look at good bandwidth control, tune down into the AM 
broadcast band with the K3 and P3. Note that AM stations are 
powerful enough that you can receive them at the upper end of 
the broadcast band even without the extended receive option for 
the K3.

When I tuned down there in the San Francisco Bay Area, I could 
see stations right next to each other, each with significant 
power stretching for nearly the full 10 KHz permitted bandwidth 
and a very small sliver of clear bandwidth between each station. 
It is a wonderful demonstration of good spectrum utilisation.
