Farhan, you must realize, the Elecraft and Xiegu radios are complete and ready for shipment right away, with warrantees. Its a fastpaced world, many hams have their noses to the grindstone from waking up till bedtime just to keep the lights on (and the tube filaments hot!). I am one of those hams. I was lucky enough to get my job back after covid, now I'm working 2-1/2 jobs just to catch up. I do have your excellent ubitx v5, also a v3, plus Sunil's enclosures, all still in their shipping boxes; someday when I can afford to shut off the fire hose a little, I can build them. I bought a Xiegu x6100 to have an actual radio that I can use, now.? As for the sbitx...interesting radio, may not be practical for me in my present situation. This is the reality... Regardless, thank you for all your wonderful creations! -- Rich

It is an odd thing though, the Elecraft KH1 is a CW only radio, selling for 600 USD. Not really, if you add all the essentials, it stacks upto 1000 USD. Yet, they sell about 3000 radios per month. Radioddity sells the Xeigus in even higher numbers.
On the other hand, QRP Labs or HF signals builds open, hackable radios at about 1/5th the price. Yet, they are an acquired taste, to put it mildly.
Some may say that those are complete radios, and these are kits or thst they are not fully functional.
Neither is true, the QMX fully assembled retaila for 220 USD, with the kitchen sink.
The basic function of an sbitx (ssb/cw) is far more stable and superior to the G90. Sure, maybe the FT8 logging doesnt work as expectdd, but the G90 doesnt have it at all!
I guess, this is the nature of open radios and will remain so. Pretty much like Linux.

I think the crowdfund could be the best way to check demand (for the assembled units).
Set up a goal of 20,000$ (200$? * 100) and see what happens.?
If the goal is not reached the money gets back, no harm to anyone.

We would produce it if there were demand for it.? It takes 100 pcbs to be viable.

200$ each, with a discount coupon for the same amount as perk.

uBITX Digital Adapter Board pinouts
Does anyone have the pinout/wiring diagram for the "Digital Adapter Board" as sold by
?
Its been a while since I bought the box/boards and now I'm finally getting to them but have lost the paperwork. I tried visiting their site to download it but nothing found. My intention is to add a small USB hub board to the back of the connector (as found on Amazon - 2 for $10) and wire the Radiuno and a CM108 sound interface directly into the box making for a single cable control/audio solution.
?
Thanks!

Re: Data recovery from a dead MicroSD card

Reverse diode and a fuse is all I use on any of my projects. Total cost about $0.50. Voltage drop equal zero.
|
I also use the fet method, not as simple as a diode, but voltage drop way lesd
I use Powerpoles for battery and PSU connections.? I also use KC9ON's FET-based devices in place of diodes.? They're good for up to 50 V and 7 A.
?
?
There are also 'ideal diode' boards that are inexpensive.? I've not used them, yet a guy with a Swiss distortion in the signal seems to like them.?

Re: Sbitx and ad831 mixer
Farhan,?
Later I would like learn more about harmonic mixing.
?
What I think I would do is to setup the bandpass filters for 10m, 6m, 4m and 2m. If fm is added later, it will be fun to operate on those bands.
?
But before all that happens have to box everything and think about power management. There is some artifacts in the audio related to that.?
?
Thanks a lot for this amazing software that gives us the oportunity to tinker and do homebrewing easier because half of the radio is done.?
?
Thanks again,?

Re: Sbitx and ad831 mixer
Peter,?
?
This the normal sbitx software with audio injector card and si5351. Have two ad831 mixers and a 10.7mhz 30khz crystal filter.
To rx clock 2 goes to first mixer and bfo goes to 2nd mixer. Sound output from the mixer goes to the sound input to sbitx software.
?
To tx clock 1 bfo goes to 1st mixer and clock 2 to 2nd mixer. Audio output from sbitx sound card goes to 1st mixer, same input from antenna in rx. The antenna is switch to the output of the 2nd mixer.
?
To do the clock swap and antenna switching im using two small relays.

Re: Sbitx and ad831 mixer
This is a nice setup, can you explain it in a bit more detail, what frequencies are you running on each mixer, I assume the second one is a fixed frequency, and are you pushing the output into something like a zbitx to generate the waterfall ?
Farhan,?
?
This is a video of a ssb tx test and how it looks on sbitx v1 spectrum.?
?
For mic bias I used 10k resistor to 5v and 4.7uf capacitor. No mic amp.

Re: Sbitx and ad831 mixer
With the AD831 mixer, you should be able to use 3rd harmonic mixing and go upto 435 Mhz
Farhan,?
?
No band pass filter in place yet. Just wanted to see if it was generating rf.? Need to decide which bands to include since the need to filter per band.
