It would be nice if there was a speed control option that you could set
based on what mode you're using. If it is a DC motor I guess one could be
homebrewed with a voltage regulator. What happens if the filter gets too
hot, is it permanently damaged?

To the guys using the high power VA6AM...


I'll be solely SO2R, never M2.  So only one signal on the air at a
time....legal limit (really)  The smaller fans are what I'm getting on the
BPFs except for 10 M.  On 10 I'm getting the bigger one which I believe is
100CFM.  I know the smaller fans are pretty quiet, but the larger one is
pretty noisy.


Any thought s as to the necessity of the bigger fan for 10  and how noisy
are the fans?  The whole set up will be under the operating desk in the
kneehole.
