I temper my feelings about closed designs, when I realize that a lot of CPU and Floating Point designs are closed. Some have no qualms about using an ARM CPU and then stress over the modem. Regardless, I won't get into that. I do think Hams are missing the boat with the FM blinders at VHF and above. I'd really like to do do a digital I/Q modulator interface. USB3 or better, connected to a 12 watt transmitter. Separate antenna jacks for transmit/receive. SDR receiver, with 16-bit I/Q channels. Full duplex, with four transmit channels, two of which can be changing frequency, while the others are transmitting. (To enable Frequency Hopping, using (B/Q)-PSK or FSK). I'd even go $30 :-) ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Freetel-codec2 mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freetel-codec2
