Re: #ubitx #ubitx-help #v5 Where to buy power socket #ubitx #ubitx-help #v5

A three wire AC plug seems an excellent (ie, free!) choice for personal use.
Could key it by soldering a copper tube over the ground lug, and trimming the ground lug
socket off of the mating power cord that runs over to your power supply.
Add big red letters above that connector on the rig stating "12VDC".

Re: Rugged Case Options? #ubitx

Rob,

I'm guessing that your replying to my post of over two years ago:
    https://groups.io/g/BITX20/message/36989
about this $10 case:
    https://www.jameco.com/z/CMC11949-R-Case-Metal-7-3-L-x-6-3-W-x-2-75-H-50-Cs_208929.html

It is made of two U shaped pieces of sheet metal.
The white bottom part is of aluminum, about 0.045 inches thick, easy to flex.
The black top part is of steel, around 0.040 inches thick and plenty stiff.
The the white part has two upturned edges along the bottom about 0.400 inches high
to which the top part attaches via four sheet metal screws.
The front and back panels are not supported other than by the bend in the bottom U,
though you could screw hidden L brackets into the black cover to offer that support.

It's plenty good enough for my needs.  The thin aluminum is easy to cut holes in.
As stated in my original post, a tight fit from side-to-side, but that's not an issue.
Top to bottom is almost twice as high as it needs to be for the stock uBitx heatsinks,
but you need most of the front panel space anyway unless you mount the display
to the top surface.  This case could easily be trimmed down if you don't want it so high.

Vents are not a bad thing, the IRF510's do need to get cooling somehow.
If you plan to be operating from a mountaintop in a hailstorm after lugging
your uBItx in a backpack otherwise full of rocks, perhaps you need a thick extruded
aluminum case with the IRF510's somehow bolted to that case to sink heat.
Most of us can get by with wrapping a relatively fragile uBitx in a spare stocking hat,
and then stuffing it along with antenna and battery and tuner and mike and key
and a bottle of brandy into a good stiff box of some sort.

Here's how ND6T did the heatsink on his Bitx40, this will also work on the uBitx:
    http://bitxhacks.blogspot.com/2017/01/nd6ts-approach-to-heat-sinking-irf-510.html
Alternately, could remove the IRF510's, bend the leads up 90 degrees from the front face,
and then solder them to the bottom of the board and bolt them to the bottom of the case.
They must be insulated from the case.  Keep the leads about as short as they are now.

I'm sure there are plenty of others in the forum with other suggestions for a case.

Re: No XMIT, No Recv #v6

k7ome@...
 

I agree about the defaulting the EEPROM idea, Jerry.  That's why I put that into the code yesterday.  I made a short demo video of the changes I've made to the software for my ham club and put it on YT.  If you're interested you can see it here:   https://youtu.be/hrWwwUSk6hU         The changes include frequency locking, and organizing two sub menus to get rid of that long pause used to access Setup.  Restoring the calibration values for Freq and BFO makes recalibrating the radio much easier .  

Just trying to make it more user friendly ....

HI,
     Can anyone tell me where i can buy the on/off/volume control for the V6 bitx mines broken off. dave

Re: sotabeams filter installation

howard winwood G4GPF
 

I don't think the volume level would be high enough, I assume it was originally intended to be an add on to a rig that took it's input from the phone/speaker output then feeding a separate amp, hence two volume controls again. Trying to get it to work with just one vol control would reduce it's capabilities somewhat. Yes ! It would make installation much easier, but..............!

Hi Jerry,

thx you, it's a good start to check.
my ubitx run with v5.1 firmware (that i can see on the screen at startup)
my oscilloscope can up to 50mhz,
yesterday, i have cheked the rf connector, i use SO239 instead BNC because my antenna and TOS meter is already PL/SO239

i 'll check this weekend, relay, coils, and test point, and back to you.

Hi my name is Tony ei3it, A friend of mine left me in a uBitx he built which has a problem the raduino nano witch seams dead no reaction from it the display lights up but nothing happens, so put my raduino nano into his unit and away she went worked perfectly.
Now I was trying to get a complete board but no success so fair, I wonder how could I get help.
I have heard that chaps have built a version I wonder could I get 1 or 2 of them depending on availability HI Hears hoping some one can help, thanks

Re: #ubitx #ubitx-help #v5 Where to buy power socket #ubitx #ubitx-help #v5

 Some hams I knew in Californicated were using 120 V AC plugs on their radios. However, that is a piss poor Idea, considering what that voltage can quickly do to an item made for 12VDC, should someone happen to plug it into an AC outlet.
 The Powerpoles are nice, but a bit costly.
 I bought some sockets similar to the ones that came with the BITX 40 and the ubitx, as far as I know, on EBay pretty cheap. They are still pretty much ideal for the BITX and UNITS radios, and low cost to boot if you shop a bit.

If I were putting in another power socket, I would use Anderson Power Poles. They give a positive connection, and are unlikely to be cross polarized.
I use them on everything!

Re: bitx 40 pcb

Wayne Leake
 

For anyone interested in bare boards for BITX40 and 20, amateurradioits.in still has some different ones available.
 The one I purchased uses certain social SBL something mixers. One they sell uses ADE something mixers, and some use easy to make mixers.
 Just a thought.
 I might buy an older version board later on for future use.
