[TenTec] Noise from Fans

[Rick - DJ0IP / NJ0IP]

A few diodes would be cheaper than lots of beer.
You don't even have to calculate much.
Just figure on 0.6v drop per resistor.
I buy these diodes generally 100 at a time.
They cost just a few pennies each in those quantities.

Thanks for the uptake, Rick.

Ah, yes... Heat.   I picked a really big resistor so I assume it is OK. 
  I will have to check it.  The guy who maintains our 17-site repeater
system specified the value for me.  I buy him lots of beer ...
