Re: Can we start using SUBGROUPS? uBiTX, biTX40, QRPKITS, Original BiTX20, Homebrew, Other?
If you need to, you can mute threads. Unless a mod has the time to sort threads on top of the basic duties forget it. Its a nice idea that will never be implemented. The reason being that its not

Sorry; can't edit... I'd say just a FEW groups - the major topics, maybe? No more than 3 or so?

Re: Can we start using SUBGROUPS? uBiTX, biTX40, QRPKITS, Original BiTX20, Homebrew, Other?
I vote YES. It's difficult to suss thru different threads - so much so, I've stopped reading it (to a large degree). I have a 'first gen' (Ver 3 PCB?) - and an older BitX20.? It's just hard to wade

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
?Great! Perhaps it will help some people who are concerned about the harmonics. The total cost of the kit boiled down to $2.50 or less for the board when purchased in quantity of 10 or so from China

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
Right Gordon, I will study the documents so I might replicate a hopefully reasonably good copy of it. Thanks very much!

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
H? iz oos - I can't really provide "kit service" since I'm a physician by trade and this would take way more time than I am able to commit to the effort.? Perhaps some enterprising soul (or company)

Re: Raduino Fix
Something to note.... I've had much better luck using the 3.3 volts from the Nano than feeding 5 volts to the Adafruit Si5351.? Your mileage may vary, Jim? W0CHL

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
Gordon, These spurs start from 0Hz and move up at the rate of 5x, 4x, 3x of the amount the display changes with center is at multiples of 2.5MHz. Example 15Mhz everything almost vanishes but at 14Mhz

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
Hi Gordon, That is interesting, relays that are polarity sensitive. Maybe that is how they make a "sensitive" relay, by adding a bias magnet inside. I downloaded the data sheet and see the +- on the

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
Given the tools you have used and for the fact you applied the KISS principle, you made a condiderable work Gordon. Are you planning to provide a kit with detailed information on connections and cut

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
I ¡®d like to point out that if the relays are placed on the (normal) TOP of the board, they would work fine as wired & not require the rewriting I had to do. Board was laid out correctly with

Ok, it will never be a Ford Cosworth, but at least LPF will polish the tricycle...

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
promising results there Gordan. While I would love to pursue mine further, but the problem of fitting it into the existing case is a problem.? Might look at another way or flatter relays! or bigger

Re: Odd Raduino, How do I Connect it? #bitx40
Thanks for the clarification Vic, it?s a bitx40. They have the same hardware now for the kits. I also have an older version of bitx40 with the original Raduino version. I?m on track now. And soon

Re: Can we start using SUBGROUPS? uBiTX, biTX40, QRPKITS, Original BiTX20, Homebrew, Other?
Subgroups is a good feature. QSO parties and raduino can definitely be in subgroups. QSO issues in USA wont interest many.. some may not want to follow the raduino discussions. Anyone interested can
