Hello Ribbit users!

I used the OFDM modem source on GitHub to turn it into an IP modem, with 
this the Ribbit modem becomes a TUN adaptor in Linux to establish an 
Internet Protocol (IPv4 and IPv6) link capable of jumbo frames up to 
about 5kB. I want to thank Ahmet for his great work on the modem!

This was purely an experiment to see if it was possible, but the results 
are surprising in my testing, sending an ICMP ping over 2000km on the 
11m band as a test, but I don't have any other stations to communicate 
with and I haven't found much interest in it among local operators (yet).

Are there any North Americans or Australians (or anyplace I can get a 
signal to from New Zealand) here who would be interested in some 
Ribbit/Rattlegram testing over HF? If so feel free to contact me!

Cheers,

Stuart ZL3TUX
