Re: zbitx getting ready to be shipped ...
Mine is Wednesday as well! Now I hope there isn't a sudden labor strike or quantum black hole to stop loading of cargo craft or sucking them up out of the sky, like the Malaysian airplane that disappeared... Looking forward to? the zBitx! -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Mon, Mar 24, 2025 at 7:32?AM David T-- VE3TOS via <digiital=[email protected]> wrote:

uBITX Calibration
Hi,
I have massive problem with my uBITX v5 for Calibrating.
When I set the Calibration: eg +10 for the accurate 700 Hz on 14996.000 in USB then press the Mic Button - says calib set. goes back to receive - seems ok. But if I turn the RIG off and on again - the frequency is much lower: eg bay pressing Button 14996.000 - after boot 14664.650 It look like the value is not really set, only temporary in RAM. I had this problems since I have this RIG. Also the Rig is really deaf.. only the most strong stations are received TX - I must on a given QRG go up for abt 300 Hz then is on the QRG for transmitting to the partners QRG I spent hours for resolving this - but no result.... Is there not a point ( Tp on the PCB ) where I can set the Calibration ? Have an Frequency counter/generator here, also other RIGS with are 100% accurancy. --

Re: reviving my sbitx v3
Some sources the IRF shipped is some cheap transistor reprinted and such may blow up on power up.

It is unfortunately very difficult to make conclusions; Evan is doing his best to help.? ?I'm still thinking the actual measurements are needing careful repeat and clarification; for example the sources of the final MOSFETS are solidly SOLDERED TO THE GROUND PLANE, so yes, they should always show a zero ohms to ground.? ? The DRAINS go to capacitors and the power supply so will show a transient response. |

Re: zbitx getting ready to be shipped ...
My order is awaiting processing. As someone who ran a mom & pop electronics business for 20+ years. I feel for them. You are developing the product, the work instructions, the sales order process etc. All at the same time. Really better not to apply pressure. It is much easier to fix last minute hitches at the shop rather than deal with upgrading or modding units scattered across the world. Keeping myself busy fixing my blown up QDX.
