[Elecraft] Cleaning a K3

[Petr, OK1RP/M0SIS]

Hi Bill,

the same what suggested Vic, the pressed air gun (like reverse-connected
vacuum cleaner tool) to blow the dust out I am using in our company for
rough cleaning of the testing equipment time to time. 

Important things are to protect fans (as Vic mentioned too) from the
over-spining. 

After that when the dust is roughly out I am repeating this step again on
different place (if you did not do it outside for the first time) to blow
the settled residual dust from the all boards.

After all of these steps I am removing the boards one by one and cleaning
the pins and all contact with Isopropyl on the cleaning pad. It takes time
but it will surely pay!

In any case during all of that cleaning procedure I am protecting all LCD
displays and screens with covers (adhesive paper tape) in order to avoid
getting the dust under the plastic covers, glass screens etc. by the high
pressed air gun...

Hope it helps,

73 - Petr, OK1RP
