To reinforce what Jerry is saying, pin names 0 and 1 on the Nano are used to communicate with the PC via the Serial object, so it's best to leave them as is if you expect to do any debugging. Pin 2

Whoops, had a copy-and-paste error. ?That first line should be: ? ?pinMode(4, OUTPUT); Also, while that first line is typically in the ?setup() ?routine, the other three lines could be most

Modulated CW (MCW) originally was a AM tone. So you had carrier plus both side-bands. Receivable on ordinary am receiver.

A pure sine wave into the mic of an ideal SSB transceiver would transmit a clean AIA CW signal. ?In the real world, that sine wave will be distorted, and the carrier not fully suppressed. ?But it

Aside from attempts to use the BitX for what I would call "true CW," i.e., "A1A" mode in which the carrier is directly keyed (with or without shaping) and having a "necessary" bandwidth of only a few

That's shipped out of California. If you have more weeks than you do dollars, there's cheaper.

Good grief...$4.50! Unbelievable how cheap things like this are. The Teensy 3.6 is another one: 1Mb of flash, 256K SRAM, and a 180MHz clock for under $30...amazing! Jack, W8TEE To: [email protected]

noTone(); is a line of C code that you add to the sketch. For example, if you hack the Raduino sketch to add these four lines inside the setup() routine: pinMode(6, OUTPUT); tone(6, 1000);

Sounds good. ? My head is usually down in the bare metal somewhere, and my coding style will reflect that. For a good taste, take a look at the KE7ER/pskuc.c down in the files section, search for the

After you two guys decide on your collaboration of coding, I am willing to try it and give you feedback. ?I am at the earliest stages of playing with arduino beyond the Blink and Servo Motor

Collins did, indeed, use an audio tone to generate CW in their early S-Line equipment.? The Collins design fed the sidetone oscillator into the audio section on the KWM-1, KWM-2/A and 32S-1/2.? And

Sounds like I need a higher voltage cap. I appreciate the explanation and clarification.

Jerry: Not a problem. Like I said, I wasn't sure that the expression on that one line was correct or not. Since you mentioned that you have run the code on the Nano, I assumed it was, but thought I'd
