Gracias Luiz!

We carried initial tests of this system in Mexico. The raw throughput,
in reasonable propagation conditions, is from 500 up to 4k bit/s. In
"real world" tropical region NVIS trx with hundreds of kilometers of
distance, with packet protocol and ARQ layers in place, the net
throughput ranges from 50 to 500 bit/s, depending on many factors.

Abrazo,
Rafael
