apparently, my sd card in my sbitx v3 is corrupted. I need to install a new card. Is there a complete image available for all of the software? Any recommendations for a replacement card (brand and

What is the acceptable range for voltage of the battery/power supply for the zBitx? I understand that with higher voltages there is the issue with heat dissipation as the voltage is stepped down. Is

We've discussed this since the V2 days as both of the models suffer from the same issue. There is no shielding whatsoever inside this mass-produced radio which causes all sorts of issues. Mitigating

HA3HZ, nice write up, your shielding looks really nice, much nicer than mine. :)? what was the purpose of shielding under the RPI? Ryan, i was thinking the same thing, need to shield the whole

Evan, Thanks, I personally have no interest in populated or bare PCBs, I'm happy to help Farhan achieve his social goals, providing meaningful work opportunities to members of his community. When

Yes. ?I would want a bare unpopulated board. ?I don’t intend to sell anything but have plenty of 1206 and 0805 parts and want to experiment here. ?I have already placed an order for a regular

Gordon - Thanks for the feedback! The way your note started out I thought it was not going to be good! But it turned out nicely. re: your results ... 1) Bencher paddle into Sbitx in "Iambic" mode

Ryan and Ken, PC board layout and STL files have always been the design pieces that have remained the property of HFSignals. However, there are always exceptions. For example, the original design

You want a "bare unpopulated" PCB? I'm sure you could convince Farhan to share the PCB design once it's finalized... I thought you wanted a PCB with the components installed... Ken, N2VIP

Good on you for taking this on! ?I know many others will appreciate it also. ?We all just deal with it. ?I have a drok, twisted pair and a ferrite on the display power and a flat ferrite made for

OK!!? ?I have preliminary results to report. First, the day started off badly.? ?While working to get going for morning CW practice listening to high speed ops on 80 meters, I got the amplifier

I intend to repackage one of them. ?I have plenty of pi’s here and don’t need another one? even if I only save a few bucks. Shipping a bare unpopulated board in an envelope would be reasonable

I'm not sure what a board only kit would look like, omitting the display and RPi 2 Zero W might cut the cost $30, and the case maybe another few dollars, but you're still looking at expensive shipping

You can find the circuit diagram on github in the sbitx/src/docs folder. Here is the circuit diagram link ( https://raw.githubusercontent.com/drexjj/sbitx/refs/heads/main/src/docs/sbitxv2_circuit.pdf

Gord: I for one appreciate you frank observations. bringing to light the almost ancient Analog transceiver is a god analogy. I could go further back to my Johnson Valiant with the HQ-170 Hammerlund

W9BLW, thanks for sharing your experience. I implemented this idea that I shared in message #114315 ( /g/BITX20/message/114315 ) regarding a program error. The idea came from this

When I ground it, nothing happens.... maybe there's an error on the circuit board. I'll check the resistors. It's a brand new V3 board, btw... so not homebrew.

wanted to add some comments as i trouble shoot this same issue before i was a part of this IO group. I had this exact issue and it was VERY bad, huge birdies on the waterfall and very high level of

Hi Group, I want to add an ADC chip to measure incoming voltage, could easily do this over I2C or SPI. Is there a document showing what pins on the RPI are being used and for what? We should even

Just a quick note. ?If you haven’t already try switching to the latest 64bit img of sbitx available on jj’s git hub. ?It has wsjtx “improved” installed with an alternative ui for smaller
