Sound Card 9600 Baud UseYou will get best results if you use a radio designed for 9600 use, e.g. PacComm TEKK KS-1000 radio or SYMEK TNC2H. Because 9600 baud packet is FSK (frequency shift keyed) and not AFSK (audio frequency shift keyed), and because of the very quick TX-to-RX switching times required, most radios do not handle 9600 baud packet correctly without modification. You cannot feed 9600 Packet Engine Pro "tones" through the microphone input (TX audio) on most radios. Unless the radio has a special data jack to handle a 9600 connection, you must connect the TX audio directly to the radio's VCO. Likewise you can't use the speaker output (RX audio) and must connect the RX line directly to the discriminator output. (For more information, visit the TAPR site: ftp://ftp.tapr.org/general/9600baud/ Among the newer plug-and-play transceivers, only the Kenwood TM-V7 and D700 and the Yaesu FT817 have special data settings to operate properly at 9600 baud. Others including the YAESU 8100, do not. Some multimode transceivers, such as the ICOM 275 and ICOM 706MK2G, also have special 9600 baud data settings. Some notes about 9600 baud use:
Tuning Aid Sine Wave signal sample for 9600 baud:
Generally good signal, but you can see small sparks caused
by some "bug" at either the transmitting station or
your receiver or sound card.
