[Elecraft] O'scope recommendations

[Jean-François Ménard]

I was using a Tek TDS2014 for a while... FFT function was very useful to 
calibrate filters, check CW and SSB bandwitdth, adjust SPOT tone, etc... 
Also good for adjusting power output with a 10X probe with AC rms  with 
a directionnal coupler. Many things could be done....

I recently change my Tek for a Fluke 196C with FFT function..... Not as 
good as my Tek, but very portable and rugged.... a feature that I need 
too..... a good compromise.... but for a few thousand dollars :-(

Modern scope also offer plotting feature with memory roll out.... 
sometime useful too.
