Unless things have changed, you can send (not receive!) email from an APRS client by sending a message to EMAIL-2, with a message consisting of the email address, a space, and the message text.? Keep it short (single packet!), and don't expect a reply (it's one direction).? But it worked for me last time I tried it.? Came in really handy some years ago when my wife and I were on a vacation and found ourselves at a beautiful B&B on the coast in the middle of a cell phone black hole.? No bars (the RF kind).?? But APRS worked, and we were able to let our kids know that we arrived safely and would call them the next day.? I did this from the front panel of my Kenwood TH-D7AG, which was a thousand button presses.? I expect you can do the same in seconds from YAAC simply by sending a message and typing it out.

You can also send an SMS message to a phone with the SMS Gateway.? Message to SMSGTE, with the text being an "@" followed by the phone number (including area code, numbers only), a space, and the message.? This one is bi-directional, though the initial message must come from the Ham station.

The issue with WLNK-1 is that a few years ago they implemented a security handshake (password verification exchange) as part of the connection sequence.? My compliments to whoever came up with the idea; it's a very creative way to do a reasonably secure handshake over an unencrypted link.? It can be done by hand (I've done it), but the timeout is rather short, so it's fussy to do typing from a keyboard-based client, and essentially impossible from an HT.? If Andrew's code hasn't been updated do that handshake, it won't work.
