We updated our most recent post about #NBEMS to mention a new application called #Rattlegram, which does roughly the same thing as FLdigi/AndFLmsg, except faster.

Started preparing #NBEMS demo on 70cm (438MHz) FM with fldigi running on a Linux machine and a Mac. So far FTM-100DH and FT-7900 connection works OK with 8PSK1000F and MT63-1000L on 1500Hz. More detailed measurement on modulation needed.

Been messing with #AndFlmsg lately.

It's a super easy way to send text and images over #hamradio.

There's a whole system called #NBEMS and you can make it as complicated as you want, but the easiest setup would be to just put your phone next to your radio and hit the PTT button while your phone beeps and screeches out the message.

This technique is called "audio coupling".
