What really will take the time is all the mods I have lined up Andy Just putting one together is very simple. Finding a box , cutting holes and such takes a while. I made several mods to mine. Such as changing the final transistors to another kind, several components were changed. One major change for me was to change out the 4 or 5 capacitors in the filter to widen the filter from about 1.7 to 2.3 KHz so the ssb sounds better. Then the software changes. Some from others and a minor one or two of mine. Mr.Farhan did a very good service to the ham comunity with that unit. Not very expensive, and works ok as is. Then others jumped in and have some really nice software and mods to make it really work well for not too much unless you use the fancy display that costs about what the origional unit does. Even new cases cost almost half the unit. I just hapened to have a minibox that only had a few extra holes in it that th e uBITX just fits in. ======= Perhaps they will not be the most pretty ones ,but enclosures for the ubitx and bitx40 or any piece of equipment can be easily made, at the size one prefers , from low cost PCB sheets often available at flea markets. I happily have a healthy stock. Frank , EI7KS In 1972, QST ran an article on a 80 meter SSB transceiver, solid state, and the case was mostly copper circuit board. But he used some wood to make a frame, which perhaps is more solid for a larger box than just relying on solder to hold it together. But as someone else said, there are lots of boxes out there, even computer power supply boxes, that can be reused with a bit of patching. Slap a piece of circuit board over one side to provide a "front panel", covering up what was before it. Circuit board is certainly easy to drill and cut holes in, easier than aluminum and way easier than steel. Though, the move for consumer electronics is away from metal, so the days of satellite boxes and other things that are metal are often in the post. I know years ago someone here was thinking (or maybe had) built a power amplifier in a metal "IBM compatible" computer case, which has potential, though I haven't seen a really sturdy computer case in some time.
