Good luck Bruce. If no posts are there, either they are set and working, hopefully. Here and there we can assume some failures due to nature or man made mistakes. Last week i set one v3 that had Tx

You're not the only one!? I also have a version 3 that I'm finally getting around to this month.

I haven't seen any recent posts regarding Versions 3, 4 and 5 lately.? Have they all been relegated to the junk box and everyone is buying Version 6?? Surely not all the problems with these earlier

Hi Ted, it should be pin 16. The diagram is correct but the writeup is wrong. Thanks for reporting the error, I will correct it immediately on github. 73 Allard PE1NWL

I have a built and am running the auto atu being sold on ebay,you have to look around to see what you get and dont get luckily i chose one that came with all componants at the time i ardered the 3D

Yes, that "could be an idea"... Bob— KK5R

That sounds like a relay cycling. In my uBitX V4 I needed to add a 2.2K resistor between the 5v source and the PTT line as the Arduino internal pull up circuit was not enough to reliably sense PTT

Ah. the old resistive bridge QRP AMU that has had several/many revivals across the years. This could be a worthwhile way to obtain the tuning capacitors, these are starting to get a little scarce from

Re: the N7DDC auto tuner. I looked for reviews first, decided to order it. This was a little over six weeks ago. For me, it entailed two orders, one for the circuit board and related components and

Further perusing eBay for offerings, I found other tuners. The specifications given were believable but of course they will not tell you the negatives, only the positives with a few elaborations. And

The antenna tuner kit is available on Bangood for a few dollars less. The kit is mostly complete, but has a few issues. It comes with a nice, solid enclosure. I’m not sure it will handle more than

Here's another item that may be of interest for you build-it-yourself hobbyists: An automatic antenna tuner. Costs $28 plus shipping for the kit... Here are some specs for it: Power supply range: 10 -

Correction: Total cost is just under $17.... Bob — KK5R

I just ordered this antenna tuner for my V6. Total cost plus shipping, tax, license, etc., was just under $16... Thought it may interest others here. Is rated for 15W and has the standard LED SWR

Diagram for this mod shows connecting the base of the transistor that bypasses the PPT switch as to be connected to P3 pin 16 but the writeup say pin 15. Can anyone confirm that it should be pin 16 as

Hello, I’m still working on it. I’ve done some tricoils and filters, real surgeon work. A question for: I start the realization with Kicad of the circuit for jack connections in front. How?

Hi, I am attaching a video of ubitx ver3. No TX. Get this sound when I press PTT. What could be wrong. Which relay needs to be replaced. Thanks in advance. Rajesh VU3RHU

The latest episode includes mention of a homebrew uBITX, the Antuino, the NanoVNA and other topics of interest to this group:? SolderSmoke Podcast #224: Mars. Spurs. Bikes. SDR. NanoVNA. Antuino.

Different rigs have different RFI immunity. In any case, having the antenna right at the radio is poor practice and your body movement will detune the antenna. If you will accurately measure the

Hi, antenna is attached directly to the rig. I have used that antenna with a yaesu 857 directly attached and that tx rx x cycle didn't happened. My ubitx has a metallic case but may be poorly shielded
