[Swan] Cooling of thy Swan

Sun, 22 Feb 2004 23:36:00 -0500

Well, I tried it today.  The fan is working hard due to the spacing of
the narrow slots on top of the rig, but I have had no problems with
drift today.  Since I have a variable supply, I vary the voltage which
adjusts the speed when I am active or when the radio is sitting idle.  

Thanks for the comments and especially this thread.  I would not have
gone thru the trouble this morning had it not been for that.

Thanks again to all.

Buck
