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

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

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

Unassembled uBITX; this is from the first batch shipped in December 2017.? Has the FCI TDA2822M audio chip. $125 shipped to U.S. address. I will send electronic copies of documentation via e-mail.

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

I think you mean Arduino Nano, Right? Jack, W8TEE

I forgot to attach the files.

As some of you know, my Raduino died a few weeks ago. The Arduino Uno board failed, so I changed it. The new Arduino worked, but the SI5351 clock chip didn't. I found that the damaged SI5351 damaged

Glenn --- you should get even BETTER results than I found, since your wires will be shorter!? ? More power to you!! I think it is now obvious that the "right sided relays" are a huge improvement ---

Able to charge that battery significantly and proceed with tests. All of these have a homebrew 50 dB tap on a Heathkit Cantenna, and then a 20dB attenuator at the input of the ICOM 718.? ?Previous

My own take on the end of filter relays has stalled, as my uBITX case is a bit too small to accommodate the pcb and relays. But here's an idea of it's fitting.??? AS per a previous post, seam

Get well soon. My son just had his gall bladder removed last month. His main issue was a very sore post operative belly button. We were glad his was finally removed at it was only functioning about 3%

Photo of what I had to do to fix the coil wiring [image1.jpeg]

OK....very preliminary results. The effect of putting the relays on the BOTTOM included reversing the POLARITY of the coil wiring......oops!!? I knew that, but was hoping the relays were not polarity

Rod, Your spice model is seriously wrong.? Reason common emitter amplifier gain is a function AC beta and the short form definition of that is FT/F where FT is the device FT (300mhz for 2n3904) and F

Subject says it. rOn

I am software and not good with hardware. So with the FCC reg's issue I have decided to sell my uBITX boards. I have a version 1 and a version 3 boards. I am asking $70 each. This does not include

Doesn't look like meeting before the BARC meeting will work out! Frank (WQ1O) has suggested he reserve the Red Cross room for a meeting. We could set up a "local" digipeater and do some testing. Also

Relay control wiring Brown wire picks off ground. (which is done several other places also) Brown-white picks off TX +12 V First white wire pics off KT one control signal Red wire pics off KT2 control

all those values Chris is quoting for the IN 4148 are completely at variance with data sheet values. https://www.vishay.com/docs/81857/1n4148.pdf? which is good for 100mA forward? and 100V PRV. NB
