Nelson KG7GYS has built his µBITx into “a box I had bought for some project over a decade ago and never got around to using”.
He ordered a speaker grill from Amazon for about US$2.50. He decided, like many of us, to use a pot with switch from his junk box in order to have a standard size shaft (it came out of an old Radio Shack CB set). The knobs are from an old Henry Tempo One (Yaesu FT-200). The speaker is from his junk box, as is the 12vdc fan.
We all want to know what the heck all that test gear does!
