<div dir="ltr">Hello,</div><div dir="ltr"><br></div><div dir="ltr">Not much activity in this list recently. Since my previous email I have installed and successfully run the linux modem <a href="https://github.com/aicodix/modem/" rel="nofollow noreferrer" target="_blank">https://github.com/aicodix/modem/</a> in a Raspberry version 1. I have left it up and working for several days. The script records sound clips from a 2 meter radio, demodulates the data, shows the message in an http server:<br></div><div dir="ltr"><a href="http://ea4gmz.hopto.org/OFDM.txt" rel="nofollow noreferrer" target="_blank">http://ea4gmz.hopto.org/OFDM.txt</a><div dir="ltr">and repeats the same message a few seconds later. Fellow hams around Madrid have been able to exchange messages using Rattlegram in their smartphones and a fixed or handheld radio. It works through voice repeaters too. The modem software was modified for making the algorithm faster, maybe at the expense of some sensitivity. I have not noticed a significant loss of sensitivity, and now it takes less than 100 ms to process an audio clip and decode the message, even in a Rpi 1.<br></div><div dir="ltr"><br></div><div dir="ltr">This is a temporary and experimental system. I wish to engage more people into Rattlegram as an introduction to Ribbit.</div><div dir="ltr"><br></div><div dir="ltr"><br></div><div><br></div><div><br></div><br></div><div><br></div>

This is a simple and very basic way of implementing some features that are announced for Ribbit. Looking forward to trying that app when it becomes available.<br></div><div dir="ltr">regards<br></div></div></div></div></div>
