I used the little shaft on supplied Volume control by drilling out an Al spacer (1/4') and crazy glued it to the smaller nylon pot shaft. Works great. I wanted the switch on the pot to save panel

The IRF510 gets plenty hot, a BS170 will likely blow in this circuit. ?Wear eye protection. ?T7 converts the 50 ohms to 12.5 ohms at the IRF510, you might go without T7 is using a relatively wimpy

Get to above 15 to prevent deciphering the dits/dahs. Currently still struggling to get beyond this. Even when I did my cw exam about 30years ago. G4FON program is a good solution to get this done.

hi i am reluctant to solder bits to my bitx40 board cos all the connections are on sockets and also i am not happy poking around smd components. i am there thinking of the cw board from sunil which

hi i could not find a knob to fit the supplied pot so i used one from my junk box which has a serrated shaft terry

Hi David, good to hear that v1.14 works ok with you know. Perhaps you should upgrade your IDE to the latest version 1.8.2 73, Allard PE1NWL

hi all i am trying to learn cw but can only read at 10wpm at the moment. i use aldo. are any of you cw wallers out there happy to work at 10 wpm . just to get me started terry gm4dso

That is v1.13. "Sketch uses 30,936 bytes (100%) of program space. Maximum is 30,720 bytes.? Global variables use 1526 bytes (74%) of dynamic memory, leaving 522 bytes for local variables. Maximum is

Should work fine, and not a bad idea. If you can't find 100k, could use a 10k pot between ground and the Arduino 5v digital CW transmit output, center wiper of pot goes on out to the 10k series fixed

I used a Dremel with a cutting wheel.? Worked perfectly. -- Darren, W9ZIM

I was just thinking about the comment on using the CW TX mode during antenna tuner adjustment and having to limit the key-down time. Previously you had used a 47K series resistor in the circuit to

Jack, Thanks !! Toni, IV3XHM

Charlie K?TAN Lake Havasu City, AZ More a lurker. I have a Raduino, but not a BITX yet.

If the BitX is not connected to an antenna, tuning clicks are very noticeable. When connected to a 40m antenna they,for all practical purposes, disappear. Willy W1LY

Remember to hold the pot shaft end (the part your cutting off) in the vise, NOT the body of the pot. You don't want to put that kind of pressure on the pot. Mike, WA6ISP

So if you have 4 wires how do you put that to a 3 pin male jack? do you share mic and ptt ground wires? Is this gonna work? thank you

I'd certainly fix D7 and C130, could still be the problem. ?But having it suddenly work when a meter is added from gate to ground suggests the 820k at R1 in the FLDIGI PTT circuit is not doing its

That sounds like a good theory. I was aware of the issue with D7 and C130 and thought that might be the problem. It seems like the problem doesn't occur when I have the meter attached. At this point

Follow up: Ok, the 5-2-2017 revised schematic in the wiki makes it clear where to put the agc circuit (instead of just audio in & audio out. "splain it to me like I'm 5 please") Built per the
