Hello Dan,

to sweep frequencies after having modified or created your model, push
F7, select 'use freq-loop', select one of the options 'Gain' (only
Gain, F/B and F/R line-chart); 'Ver' (vertical pattern for eacht freq),
'Hor' (horizontal pattern) or 'Full' and specify the start- en stop-
frequencies. Then click Generate.

B.t.w, did you read the _GettingStarted.txt file ?

Concerning the 144 mhz / helix problem, for now I am not able to
reproduce it overhere. I would very much like to know about this, could
you give me some more details ?

Arie.
