<h1>Vail</h1>
|
||||
|
||||
<p>
|
||||
This is a CW repeater,
|
||||
named after Alfred Vail,
|
||||
who may or may not have invented what's called "Morse code",
|
||||
but clearly had some role in it.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Just like a radio repeater,
|
||||
anybody can connect and start transmitting stuff,
|
||||
and this will broadcast it to everyone connected.
|
||||
If there's enough interest,
|
||||
I'll add something like channels.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
If you need this to work on a cell phone,
|
||||
let me know and I'll come up with something for you.

<h2>Why does this exist?</h2>
|
||||
|
||||
<p>
|
||||
I need a place to practice CW with actual human beings,
|
||||
and I want it to be as close as possible to what I'd experience on a radio.
|
||||
Also, I don't want to make people buy a bunch of radio hardware.
|
||||
Nothing else like this exists on the Internet, as far as I can tell.
