| Morse code as encryption? I'm not sure I understand.

|

| https://lcwo.net/ is a great resource to start learning using

| reduce the overall effective speed to make it easier).
|
| For the more dedicated, https://cwops.org/cw-academy/ offers a

| great things about them.

|
| There's enough simple examples in the film that it "shows you

| Whelps, I'm out then. My ears are too broken to pick up any

| GMRS repeaters (which use the same receive frequencies as FRS
| channels 15-22 if your radio has them) do not strictly require
| identification (the Morse code you hear), but many do it anyway
| as good practice. Users ARE required to identify every 10
| minutes of conversation (and at start of conversation).
|
| It's really fun to learn Morse well enough to catch these IDs.
| FWIW, GMRS licenses generally (always? I think) start with W,
| and are seven chars long; the first four are letters, followed
| by three numbers. Some idents follow ham conventions and are
| followed by "/r" meaning "repeater".

|
| One of the few things I have caught is that the end of the
| Morse code is: Di-dah-dit (or "r" as you mentioned). So that
| makes sense!
|
| > followed by three numbers
|
| All letters are 4-or-fewer dits/dahs. All numbers (0 through
| 9) are 5x dits/dahs exactly.
|
| I've caught the pattern of 3 numbers in there for sure, but
| I'm not competent enough to know what numbers they are
| exactly. I'm good enough to count "oh, 5x dits/dahs" but not
| translate (or even remember the dits/dahs after they're sent)
|
| Its not like this repeater warns me before it sends Morse
| code. It just sends it all in maybe a span of ~5 seconds, so
| its one of those things thtat I probably need to be trained
| in Morse Code before I can just remember / write down what
| was transmitted. Fortunately, it does seem to send it every
| ~15 minutes or so (I haven't timed the exact pattern quite
| yet, so maybe it is 10 minutes like you suggested...)
