Re: [amsat-bb] Echo TNC

[Stan <stan@xxxxxxxxxxx>]

Hello Bruce and the Net:

Reportedly the SDR-1000 transceiver (with optional transverters) will be 
compatible with ECHO.
SDR-1000 is the software defined radio and with optional DEMI  2M 
transverter/PA  and a 436 MHz transverter/PA.
it will be able to downconverter to the 11 KHz  I/Q (dual) channels for 
a soundcard/PC processing under windows.

I believe software is planned for:
single voice grade FM channel like AO-27, UO-14
multiple FDM-FM channels simultaneously for voice communications, up and 
down
very wide band FM modulation schemes for higher speed packet.

I am not hearing about any other terrestrial station options for the 
many ECHO planned capabilities.
Yes, SYMEK has the packet (only) equipment.

I am not sure at this time if the satellite modulation firmware is 
finalized or if the terrestrial station software
for the PC is completed.  The SDR-1000 (IF) radio is available now . 
Probably on display at Dayton.
DEMI 144.0 = 28.0 MHz low power transverter is also available as a kit. 
(150$)
