[Elecraft] [K2] No power on transmit

[Don Wilhelm]

Certainly, a 'scope will act as an amplitude measuring device for RF - 
up to a frequency limit.  The frequency rating for the 'scope as well as 
the probe must be taken into consideration.  If both the probe and the 
'scope are rated for 100 MHz, then they are quite usable up through 20 
MHz and possibly even up to 30 MHz.  The frequency rating of the 'scope 
and probe is where the response is 3 dB down, so if the frequency rating 
is 100 MHz, you will see only half the actual amplitude at 100 MHz.

Since the values listed are for RMS as read by an RF probe, multiply the 
"expected" values by 2.8 (use 3 for quick multiplication) to obtain the 
peak to peak values seen on the 'scope.
