Is there a function prototype for setFrequency() near the top of the code or in a header file? While I am not familiar with the code, my guess is that the argument to the function is either a long or

Sean Rarely can a capacitor be replaced with a short circuit. Often it is blocking DC, or filtering it. Sometimes it can stay open, but likely the cap is necessary. You result seems to say so. See if

I have a version 3 board. I tried loading the original software for the nano and I am getting an error messages. 'si5351bx_setfreq' was not declared in this scope. Part of the code is shown below. I

Rod The cw and ssb transmit paths are routed differently, so its at least possible. If you can monitor power supply current, that might convey you have more output than you think on cw. I have used

If the OP aimed at pp9 batteries, a clear NO , as even in Rx mode you need 1.2amps or so. [email protected]> wrote:

If you mean 12.5 volts, that should work. you need about 3 amps or more. Check the voltage at the power supply when receiving and transmitting to see what it is doing. Curt

Hi, Love it. The old saying “If there’s a will, there’s a way” is surely true. These days. I do bark less but I just can’t wag. Ron KJ4FFG

My first two hf radios have been the Bitx, I used a bitx40 exclusively for a couple of months before upgrading to the ubitx last winter. Yes the ubitx is not a perfect rig. We use ours for digital and

Hi Klostreich, 9-volt batteries won't last very long with loads over about 15 or 20 milliamps. That is not practical for the power FETs used in those radios. Two or three in series would give you the

No idea but something must be wrong either on the ubitx, connections, wattmeter etc. You should see at least 10w on 7Mhz. On mine I see something like 14w on 7Mhz decreasing to less than 2w on 28mhz.

Hi UBITXers I just put together the UBITX and it puts out about 3watts or so on SSB on 7mgh. Nice clean wave form on SSB and CW and I've had a number of SSB QSOs. However, on CW output is only about

Also, my power supply is only 1.25. Is that enough, or should I get a bigger one.

Hi, My volume control knob is a discarded cap from a medical syringe that had contained saline solution. The threaded hole that once sealed the syringe is the same diameter as the shaft on the volume

Since I have been monitoring all of the Bitx threads (only for the last 3 months), I have come to understand that the uBitx is a kit that really needs to be worked on to make fully "legal" in the USA.

I saw somewhere a comment about the knobs. The encoder knob is not a problem since it has a pretty much standard size shaft diameter. However, the volume control shaft is smaller. I've seen knobs on

The BITX radios are open source designs intended for hacking and learning.? They're not intended to be and likely never will be appliances.? The info's here on the forum - grab a soldering iron and

Yes. The community is also working it. In my dreams someone will offer a kit of parts, that has been verified on maybe a couple dozen rigs. Meanwhile,? available data may give you clues on what bands

The fact that it is V4 would suggest that improvements do occur. There many great and wonderful minds on here working to improve the uBITX. For that I am thankful. Merry Christmas and a Happy New Year

Mark, thank you!!!!! This is weirdly white knuckle if you are a newbie...but i will wear down the problem.? Thank you the assistance... Don km4udx
