[Elecraft] Proposed New Product

[Don Wilhelm]

Tom,

The P3 can monitor the K3 IF spectrum right now.
A spectral display is often more meaningful than an envelope display on 
an oscilloscope.  For instance, it may be hard to determine just when 
the waveshape of the envelope begins to flatten, with a spectral 
display, it is easy to see when spikes appear that are other than the 
tones themselves.
I would rely on a spectrum display more than a 'scope display for 2 tone 
testing.

Yes, it is not monitoring the actual transmit frequency, but the IF 
signal.  One could use a tap on the transmission line as well as 
attenuators to bring the output signal down to the point where it could 
be sampled by the P3 - the P3 input frequency can be changed to most 
anywhere in the RF Spectrum.

73,
Don W3FPR
