I agree with most of Ken and Lee's points.? What is not mentioned is the enormous amount of software that Ashhar Farhan used that is open source and may not be available for the "lower cost/higher

Thank you Lee for your 2? in the topic, without which we seemed to be in the dark. This seems like a new wave taking shape after "Add my name to the new order list" Cheers wrote:

Michael, The first step is to verify that the Q10 Drain goes to zero when TX goes to 3 volts (or higher).? If that happens, Q10 is OK.? If not, it is bad. Once Q10 works, verify that the Q9 tab

Evan, I have gotten things mostly straightened out, proper voltage to R77, 5.6v to D6, etc. I still get the 3v on Q10 for the Tx signal, but Q9 just doesn't switch. The voltages on the excel sheet

Yes, that is why I sent the picture.? Unfortunately, there is no tracking process for minor revisions, only the major ones, such as DE, V2, V3, and V4.? The V4 has just been announced. With

I just realized your picture does not have RD2 in it. Perhaps different revisions of sBitx V3 ??

Exactly what I would expect. Interesting that RD2 is not on the schematic. I'm befuddled as to what is happening with my PCB. I should have 11.xx v on either side of LD6. Even more so with the list of

Hi Rob, I measured my v3 mic input at 11.6 volts with a 12-volt supply, and no mic was connected. Here is the picture of the preamp area: RD2 is not there. If you want a different bias value,

Well, there ya go! change that resistor to get the bias voltage you prefer and you should be in business!! I didn't have that (to my knowledge) in any radio I have worked on, and I added resistors

RD2 ? I do not see this resistor on the schematic ( https://github.com/afarhan/sbitx/blob/main/sbitx_v3_production.pdf ) and appears to be in parallel with C29. That would make your answer correct. It

I think everyone needs to take a deep breath and recognize a few things. 1) This is new product, and to expect military precision for its release does not seem reasonable, especially with a smaller

This is one reason why I wait until a product it out and vetted before ordering one. Mike N2MS

I’m somewhat incredulous that people would urge a complete redesign of a product that is potentially days away from shipping, likely already built. The only issue is how to manage upgrades,

I sit corrected. But I wonder what the wireless in the Pico will be used for? Have to wait and see! [email protected]> wrote:

Guys, let's not speculate, the designer is not a fool. You already know him from his earlier offerings. I suggest, let's wait for the rollout and then discuss. Right now we don't know much of what's
