[time-nuts] 53132A Cooling fan

[stan, W1LE]

Hello The Net:

Mike, thanks for the 53132A fan info.

I also have a noisy fan. I have considered adding a proportional fan 
controller since more colling is needed
if aditional options are added, like a more stable internal reference or 
a prescalar to 3 GHz or 12 GHz.
Less cooling is needed if no internal options are included. Less cooling 
can mean a slower fan speed and lower acoustic noise.

Anyone have any thoughts on exactly where to put a temperature sensor 
for a proportional fan controller?
The W1GHZ.ORG website had a fan controller.

Anyone have any thoughts on how to increase the intensity of the dim 
display ?   Is it a power supply issue ?

I use my 53132A with TimeLab to measure the performance of different 
oscillators.
