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 On Tue, Jul 17, 2012 at 3:30 PM, István Szabó <[email protected]> wrote: > I am concerned about falling metal chip, small wire or even the tip of > a pencil into the trx.
