[Elecraft] Return to the list + K3 panoramic adapter

[A.K.Forrest]

Dear All,

  have been off the list for a couple of years but have been using my 
K2/100 as my only rig, mainly psk31. The K3 has brought me back to 
see what's going on.

Its probably a bit late to make suggestions for the K3 and anyway the 
relatively minor problems I have had with the K2 and psk31 all seem 
to have been addressed in the K3 design, however there has been 
mention of a future band scope/panoramic adapter. Can I suggest as 
well as monitoring incoming signals graphically that the same could 
be done for the transmitted signal. I have continuous monitoring of 
the PSK IMD  (with kk7uq meter) which is very useful. Its very easy 
to overdrive and cause splatter. The system would need to display 
about 40dB dynamic range to be useful and, of course,  be able to 
display frequency peaks 31Hz apart.

The above facility would also allow testing of the entire signal path 
for distortion which would be useful for SSB as well and would seem 
to fit well with the K3 facilities for psk31 reception
