You can download source, compiled hex file, etc. from the link below.

How to upload Hex files can be found in my blog below.

Thanks for your interesting

Is there compiled version available somewhere?

There is also https://amateurradiokits.in/store/metal-enclosures/ that seems to work pretty well.

Care and Feeding of SMD Parts

Jack, W8TEE
 

A couple of weeks ago I mentioned that I was using more SMD parts and was looking for an assortment. Some assortments are sold in "folders", but being cheap, I went with vendors who sold components "loose" in strips. I ended up storing the parts in cosmetic sample jars (see eBay #161987389187). Make sure that the jars don't have recessed bottoms, as those won't work the way I mount them. Each jar has a 1/4"x3/4" piece of Velcro on its bottom and a label on the lid. Anything bigger than that "sticks" too well. Velcro is sold at Lowes in 15' strips, which is more than you need. Long strips of Velcro were stuck to a board and mounted on the wall:



I found it difficult to peel back the covering on the strips, so I used the edge of a box cutter to split the strip in half. It doesn't matter if the "half" includes some of the backing paper, too. I then took a sheet of 11"x8 1/2", creased it in the middle, and took the now-separated strip and slowly spread it apart. The pieces pop out onto the sheet easily and the crease makes it easy to load them into a jar. Label it and stick it on the wall and you're done. When I need parts, I just pull off the values I need and place it on my work table. (I've ordered more jars and I have more components that I can mount this way.)

Obviously, you could store the parts in a plastic multi-compartment storage box like Harbor Freight sells. However, if you're the least bit klutsy and ever bumped the box off the table, you'll quickly discover that those compartments don't always fit tightly against the lid when it's closed and parts can bounce into other compartments. If you're really having a bad day, the box pops open after the fall and the resulting SMD shower is impossible to clean up, especially when your shack has camouflage carpeting. Anyway, because I only open one jar at a time as I need it, disaster can only befall one value at a time. For casual building, it works for me.

Fixing a blown Raduino board

Hi All,
I managed to fry my Raduino board somehow.
The board is hard to come by at the moment.
So, I ordered the parts via Ebay.
Looking good so far...

Dynamic mic on ubitx

Dennis Yancey <bigbluedry@...>
 

has anyone used a dynamic mic on the ubitx? If you have, please givedetails such aspiring, did you use any preamp, etc. also what were the results as reported by others?

thanks.

Good solution !
Neat as well.
I have sneezed and my SMD components became vacuum cleaner fodder...

Then I put my SMD project away for a while and lug out my unfinished 813 valve RF amplifier project !
Try sneezing THAT away !

I did that twice. The best investment I have made in a long
time is an 40 watt soldering iron with a built in solder sucker.
Worked really well for removing the nano I love it.

Thank you qq for the procedure (I know). This is to know if the ubitx must be powered or not when transferring. Thank you

Re: UPLOAD FIRMWARE IN RADUINO

The uBitx does not need to be powered to upload the firmware. The Arduino nano will power itself from the USB 5V when connected to the computer for uploading.

Yes..the resister is there...i am able to transmit out with a key and thru the mic so output is not an issue..it is just deaf

I always remove the power before upgrading.  The Raduino will get power from the USB connector & computer, while being programmed.

KD1JV SSB Kit for 20m

Jerry Gaffke
 

Those interested in the full kit building experience using surface mount parts should check out this:
     https://groups.yahoo.com/neo/groups/AT_Sprint/conversations/messages/18355
The manual is here, you need to be a member: 
     https://groups.yahoo.com/neo/groups/AT_Sprint/files/slopbucket.pdf
The name comes from a 60 year old term for SideBand operation,
as voiced by the now mostly extinct AM phone guys.

Steve's pricing it at $60, first run is 48 units, will likely be gone within a few hours
after being made available in the AT_Sprint forum. 
US customers only on this first run of boards, as there may be some bugs to ring out.
Perhaps best to wait for the second run, let the denizens of AT_Sprint have their fun.
Some of Steve's kits eventually show up at qrpkits.com or lnrprecision.com

Take a hard look at the si5351 on your Raduino, building this new kit involves soldering that guy down.
It's tiny, with fairly tight pin spacing.  Steve recommends putting the parts down into solderpaste,
then heating the board with an embossing heatgun and/or toaster oven.  I'd expect all but the 
si5351 will be easy to hand solder, and the si5351 possible with the right fine tipped temperature
controlled soldering iron.  Plus a stash of flux and solderwick to clean up all the solder bridges.
C's and R's are all surface mount 0805's, smaller than the 1206's used by hfsignals.
Arduino sketch listing is included in the manual.

The rig is a 7W SSB/CW/Digital transceiver for 20m, using an ATMEGA328P and encoder and si5351 and IRF510.  
In those ways it's comparable to the Bitx, but otherwise a significantly different implementation.
For example, no relays, he's using a couple 2n7002's for TR in much the same way that Gary has suggested.
Mixers are 612's. has a 5 pole crystal ladder filter at 9mhz, audio agc.

Some nice touches, such as an LED to indicate how high to turn up the mike gain.
The user interface on Steve's rigs is usually well thought out.
