Unfortunately, that battery is only rated for?235 mAh.? On a BITX40, it would have a short, but happy, life.

Yes, I had microphonic issues with my board. After removing and replacing the boards multiple times for other upgrades or issues it went away. Still not sure if it was flexing the main board or

Bill, Thanks for the tip! I've checked out www.websdr.org ( http://www.websdr.org ) but it never occurred to me to use it in that manner. I may have to try that. ? 73, ? Jared KN4IYL

Woody, I have issues with microphonics too, but with my ubitx on a decent antenna they get drowned out from other background (band) noise. I only notice them if I am on a dummy load or have the

Hi, Are you familiar with WebSDR? Those are SDR receive stations that are shared over the web. You can find them in various places covering various parts of the spectrum. Multiple users can use each

John We are doing a group build of 23 rigs, many more behind you. Check out 2 versions of nd6t agc, to cure that. Yes cw via one arduino pin, you can get used to it. I may try w0eb firmware and

Mike, Interesting link but as you suggested, the most likely would be RF intrusion. Was transmitting (into dummy load) when failed. Still wonder why, since it was the "nth" time the xmit was on. Wire

I was lucky enough to get this one. If you have a chance to deal with Joe in the future, don’t hesitate. A true man of his word and a joy to get to know. thanks, Joe. -- 72 and God bless KD4EPG

Have your tried KD8CEC firmware??? It should fix keying issues ... it has for most, although some have gone to using a fixed digital pin.?? Lots of ways of fixing that problem. However, the KD8CEC

Woody It's pretty easy to kill a nano.?? See https://www.rugged-circuits.com/10-ways-to-destroy-an-arduino/ And it may have been RF, putting the connector on one pin out of line, and a whole bunch

I got my uBitx going today and already made some contacts. I had to rewire the socket for the keyer but other than that all worked OK out of the chute.? It's presently using the v0.20 code Things

Solved... Thanks to a comment from Jim, one problem solved.?? Idiot me did not adjust the display contrast before deciding the kit had an assembly problem.?? A tweek of the contrast pot, and there

Bill, you caught me. The receiver is about a foot away. Lesson learned, and thanks for everybody's input.

Hi, How many kilometers are between the receiver you are using for tests and the transmitter? If it's in the same room you don't stand a chance. 73, Bill KU8H -- bark less - wag more

Hi, The capacity of an Energizer coin cell of this size is 235mAh.? That would last you maybe 1.5h max on receive only; much less with some transmitting. 73, Mark.

The CR2032 is designed for applications with very low current draw. It's spec show standard discharge rate is 0.2mA. So you would need to parallel many cells to get the power you need.

I would use 4 individual holders. Then, mount them to a piece of circuit board. Like:? https://www.adafruit.com/product/653 I would check Digikey.com also....

Thanks, but nano died during operation.? While I cannot transfer data with it (does connect), I can connect and move data fine with the second nano.?? ... And the second nano works with the

I was thinking of powering my new Biitx40 with 4 2032 lithium coin batteries, but I don't know how to create a holder for them. Does anyone have an idea? Also, is this idea even feasible? Thanks so

Addendum to the above: It's not so much a squeal, more like a noise you'd hear on Space Invaders or Galaga or something. Sorry for the non-technical explanation, but I don't know what else to call it.
