For the price and ease of assembly, it is hard to beat the Emtech ZM-2 manual tuner.

Re: A short video of sBitx working
Very nice, and some fascinating capabilities.

I¡¯m hoping I have enough time while teaching part-time high school this semester to delve into some of this code! Gordon KX4Z On Jul 31, 2022, at 10:30, Ashhar Farhan <farhanbox@...> wrote: |

Aaron, The best thing to carry to the field is an L match. A variable cap, even the polyvaricon, and a tapped inductor should tune anything with a good match. - f On Sun, Jul 31, 2022, 9:03 PM Aaron K5ATG via <k5atg=[email protected]> wrote: I think that I have everything to make a little tuner, like the air variable capacitors but I have never used a manual tuner so I would not have a clue as to what I am doing.? |

Re: SBITX assembly
Hi Ashhar-? Yes- I have been following you and watched your intro to sBitx on YouTube about a year ago,? I have had more fun building the uBitx than making QSOs with them! I am sure there will be a few challenges with sBitx, but that's what makes it interesting.? This is certainly better that trying to get 40 or 50 year old boat anchors back on the air!? Plus it is state-of-the-art.

Re: sbitx board set
Yes, but the board sets (now called the basic kit) goes out onMonday. The fully assembled kits have mostly been shipped. On Sun, Jul 31, 2022, 6:08 PM Don--AE4DW <AE4DW.Don@...> wrote: Congrats!

Re: SBITX assembly
I hope you like it. It is the most fun radio. A little quirky as I had no experience working a big gun radio. I just saw online videos to see how they operate and built it up. - f On Sun, Jul 31, 2022, 6:19 PM <msamis@...> wrote: Thank you, Ashhar.? I will be ordering soon.? I have so far built uBitx versions 4 and 5 with Nextion screens and Inkits enclosures. I also have a version 6. Can't wait to play with sBitx! |
Re: SBITX assembly
i ordered that exact one yesterday, same day delivery at no extra charge. it arrives, the box is somewhat crushed, and the display is mangled. Attempt number 2 arrives Monday. Dig-key also has them, slightly lower list price, but as a single item, by the time you add shipping, especially if you have Prime, its no better than a wash.

Re: uBITX SWR Tolerance

Or if you have worse SWR, make an easy tuner:
For QRP the plate distance does not need to be large. If you use only one band an end-fed wire could be even more easily tuned: Enjoy! |
