Re: wrong frequency after software change. #ubitx
Thank you Jack, the problem is that it shows all the same name because it takes the project name uBitx20. Every project I downloaded has a new folder name but inside Arduino it shows uBitx20. That is

My Bitx40 90% done
Here are some pics of my Bitx40. I used a Harbor Freight ammo can. I will be putting a small battery inside. I havent decided on what I'll use for a mic. This one works fine, but only

Re: Blown by nearby transceiver #bitx40help
He did say "no antenna connected" though that is not quite the same as saying "nothing connected to the Bitx40 antenna port". Perhaps he still had coax from Bitx40 into the tuner. Then a fault in the

Re: Blown by nearby transceiver #bitx40help
I think I am with Chris on this. Early on, I fired up an Icom 735 a couple of feet away from the Bitx40 and it did indeed take out Q13 but left nary a mark. Pat

Re: Lost audio from receiver
Put a socket in. That way you only need to fix the board once.. lm386 chips are cheap.

Re: Blown by nearby transceiver #bitx40help
Looks like C131 has also flashed. There is a dark area as if has burned.

Re: Blown by nearby transceiver #bitx40help
My guess is he made a mistake and the 725 was wired to the bitx via coax and atu the poor bitx got a big dose of rf it can be fixed [email protected]> wrote:

Re: Blown by nearby transceiver #bitx40help
Very curious.? Blowing R131 and R132 might be due to a very large signal showing up at Q13, though I would expect Q13 to blow first. In your first post it says: I would think the Bitx40 would have

Hi Jack, I hope your response was in jest! I once gave a four session training package on financial planning to the docs at my institution and I told them the last session would be way off the beaten

Re: AGC kits
The actual resistance will also depend on the input resistance of the final amplifier. For instance, if the volume pot is set to maximum you would have the 10K pot in parallel with the input

Re: Aluminum enclosure
6" x 6" is what it needs (for a very very tight fit). At least 2-1/2" inches if you are on standoffs. The stand-offs are 1/2 inch, the display is another 1-3/4 inch above the PCB.
