Enclosure for BITX40
|
http://m.banggood.com/Electronic-Plastic-Shell-Cartridge-Handle-Project-Case-Desk-Instrument-200x175x70mm-p-1035473.html?rmmds=search I had ordered a couple of the Banggood cases and finally got to mounting my BITX40 in it. I'm not done yet but wanted to share some photos of my work so far too give others an idea of whether or not it would fit their needs. I've found it to be perfect for what I wanted and just $10 with a little patience for the delivery out of China. Receive is working great, still figuring out the mic arrangement. So it's a work in progress!

I would suggest Roy and others to try out shielding tape . This is from aliexpress and appears very cheap and just sticks. regardsOn Wed, Feb 22, 2017 at 8:11 AM, bigdswitzer <bigdswitzer@...> wrote:

VERY nice enclosure. Just a swell implementation. Mike Yancey, KM5Z |

I haven't got my BITX40 yet but I'm planning to assemble it in??case complete with internal battery power. ?I received the case yesterday (3 day shipping from IL) and it is of high quality (though heavy for my intended SOTA use). Being aluminum, it eliminates the need for copper tape for RFI protection and can be used as a heatsink for higher PA output. ?My layout will mimic that of ?who has kindly provided measurements for his layout. ? Heat sinking the PA to the chassis should be possible with JAMECO part #2227284. 1/4" and 1/8" knobs can be found as parts?2239120, 265051, or 265077. I plan to use my BITX40 from a backpack, powered by 3 LiPo batteries in the case. Both speaker and mic will only be from an external setup wired to a 4 pin headphone jack compatible with my Samsung smartphone earbuds and a recycled speakermic already made up for another homebrew project. So, I'll run that through a single Jameco part 2201607. I think I'll add RF gain control and an external barrel connector in the back in case I want to power from something else. I'm also considering adding a small bluetooth audio option but that may not work with the 100% metal case. Keep the ideas and results coming! Cheers, Peter, K3OG |

Just had a 2.5" speaker laying around that looked like it would fit and it did. Not the best sounding but it works. :-)) Roy WA0YMH Carrollton, TX On Feb 21, 2017 8:41 PM, "bigdswitzer" <bigdswitzer@...> wrote:

¿ªÔÆÌåÓýThanks Larry. Is it "sticky"? We don't have Home Depot in Australia but I dare say the local hardware chain might have similar. I can't recall seeing copper flashing but I have seen aluminium, sorry - make that aluminum for all you in the USA. Bill, VK7MX On 23/02/2017 12:46 AM, Larry Acklin

You might try your Arts&Crafts store. Copper tape is used
in making stained glass windows, among other things. I have found both copper and pure tin of use from there. Even if it is too thin, it can still be used for lots of things, like soldering the tops and bottoms of pcbs together around the edges to make a good ground. And there is such a thing as sticky copper flashing, so your local HI store or lumberyard might carry some. john AD5YE |

Daniel: I think most people simply hacksaw the shaft to their needs. When I was testing the original Raduino, I could not find a knob in my junk box that fit...they were all too large. Two layers of shrink tubing provided a fix until I could find a better knob.
