Junkyard uBITX #ubitx
|
Rob Snow
I've seen a ton of beautiful uBITX builds, I thought I'd add my junkyard build that I just completed earlier for the other end of the spectrum. My wife was going to throw the tin away, so I grabbed it. Some drilling and snips later and it is alive! I've got the WX audio chip, so I installed a 8ohm + 8ohm speaker and am running it at 12.0v from 13.8v with a step down that is pictured.
Tried some 80m and 40m earlier, but it's pretty horrible tonight. I could hear a few folks, but no response to CQ so far. 73 Rob AG5OV

I thought I'd update this for the "junkyard" types out there. Here is the digital rig. RPi 3 is usually my backup APRS setup, so a Baofeng audio discombublator is on top. FT8 QSO's from Italy, Cuba and Venezuela today from Central Texas.
Audio isolator to the right (2k + 0.1uF and 600:600 transormers), I used some cheap 3.5-3.5 cables peeled and split with teeth. Multimeter can be seen on the input side setup for current monitoring. I didn't have any alligator clips, so I spun the wire around the multimeter leads and used the caps as clamps. 1.8MHz high-pass on the right/top, local AM station overload.

Nice!
what is the WX. Hip? secondly does all of our workbenchs look the same. Good thin the cases are flat in the back to push the last broker further back on the bench with all the leftovers! n2aie

Love junkyard radios....this is my Bitx40....notice the crisp lettering on the front panel....AKA as Magic Marker...And the sloped front panel like a real Bud Box. Neat tight wiring harnesses....oh yeahhhhhh....BUT it works. ...And Allard's mods and software changes were coming fast and furious so every week I was drilling holes in it, This is my breadboard radio...the finished product is even worse....hahahahahaa Don

Don,
Love it! The junkyard movement is strong here. You went all Cadillac with the magic marker, that's sharp :-) I secretly have a 2nd uBITX still in the packaging and have learned a thousand things on the first one that I didn't know that I needed to know, so it's already served it's primary duty and I've made over about 40 QSO's with it too.

I'm really thinkin' the ubitx.net site is missing out here....A ham radio reality blog- "Dogs of the Workbench". Or something.....Aloha, Steve WH6ST

Ha! If there's demand ... I could easily start another gallery just for those "dogs of the workbench"! Of course, these "dogs" may be a bit of a discouragement to the way in which constructors are presenting such excellent builds, and innovating like crazy in the µBITx community! Mike ZL1AXG

BTW - I think Guy is having us on, and
he really does have a nice replacement front panel for his build
that he has chosen not to reveal as yet! M

Norm, personally, I find Radio Surgery to be more rewarding...and besides, if you mess it up all you need is more solder and another filter of some sort and nobody will ever know!

Yup love radio surgery....its more rewarding than most QSO's I've had....and I've been a ham for over 40 years.
Got an AGC and mic audio compressor on the bench now...going to finish those up and duct tape them onto the board... I do that cuz I know they're not going work the way I want them to. More surgery needed.... don
