First off, what version of uBitx?? If it is not v3 or 4, then you need the 1.2 version of the CEC software.? The IF for the v5 boards is different and requires a different software version or

If you downgrade back to the version you were happy with do you still have the same results?? That would at least eliminate propagation changes or hardware issues. -- www.bitxmap.com (

Probably missed matching the firmware with your version of hardware as filters have changed in V5 of the hardware. Are you loading the hex files or compiling/linking the source code?

Hi all, First thanks for all the good advice on correctly wiring the mic. It worked and the uBitX project is progressing nicely. I made three contacts in TX,TN, and LA from VA. Every time I tune

Thank you Allison for the answer. So if I put the PA voltage from 12v to maybe 16v it will not worth the pain regarding the final output power? -- 73's Adrien F4IJA https://www.qrz.com/db/F4IJA

Have you tried Memory Manager to see if anything changes? I had problems at first because my changes didn't seem to take. What I did: Power off Ubitx and connect USB cable from Ubitx to PC Start

Running th efinal at high power with 100ma bias means that at 12V your heating them at 1.2W no signal.? Bring that up to 24V and its 2.4W of heat. To run at higher voltages you need to insure the

Thanks gary, yes i'ved tried to push ptt longer but nothing changed...yes i see "calibration set! Etc" message...on power on everything is lost...maybe a e2prom defect in the arduino?

Hats off Allison for a nice treat in this poat . Messages are crisp and digestible. Many thanks Regards vu3zmv

Hi Adrien, See this post: /g/BITX20/message/53765 73, Mark.

Jerry : that's OK, I've figured out why there is 2 power slots. I've asked here another question though :

Hello, What is the max PA PWR that can be supplied to the ubitx ? Also, what is the output power benefit to have more voltage on the finals of the PA PWR ? Thank you, -- 73's Adrien F4IJA

Thank you Jerry, For now I've just reworked the drawings, based on the old one. It's better quality and very good to print. I've some questions on my side too : What is really the difference beetween

Hi, This one looks like it has no low pass filters installed, thus it would be illegal to use in most countries unless band-specific low pass filters were used between the amp and antenna. 73, Mark.

Eric Wonderful offer. I don't know Thom but remember him from qrp-l. In my judgment a small team of builders can take turns working on his rig, in parallel with your own rigs. Important is to find out

Good to have an alternate drawing of how to wire up a uBitx. We often have questions here from puzzled kit builders. However, The 2 reverse protection diodes should be after the fuses, not before, so

I ordered RMItaly KL203 and will give it a short to work with ubitx once it arrives here.

Hi everyone ! OK, you'll now find the new version of the wiring diagram in the wiki : /g/BITX20/wiki/uBITX-Assembly You will now be able to download an HD PDF and also, in the CAD
