[Elecraft] Grill Cloth on K3/10

[Guy Olinger K2AV]

All venting is required and is specifically engineered for needed cooling.
 Grill cloth on the speaker is to protect the speaker.  Do not add
additional grill cloth.  Do not cover up venting by placing books, and
other objects on the K3 without "feet" or other means to maintain spacing
for air circulation.

Heat is the worst enemy of all electronics.  I have heard lots of stories
about components going down to heat.  Can't recall any stories about metal
filings shorting out the electronics.  Should a K3 (or any expensive ham
electronics) be in the same place as flying metal filings?  Electronics for
manufacturing environments is specifically engineered for that kind of
environment.

Some people build special cabinetry around  their ham gear which both
protects it and maintains spacing for air circulation.  W0UCE has a lovely
special cabinetry he made for his K3+P3+KPA500, etc. with hidden holes in
shelves to maintain unobstriucted free air flow.  Looks good, works good.
 Protects. Cool.

73, Guy
