 Download the latest versions of Soundmodem and Easyterm from [[https://uz7.ho.ua/packetradio.htm]]
+To improve decoding with Soundmodem go in the Modem settings and set Add. RX to 3 pairs. This will help decode signals that aren't exactly on the same audio frequency. Also set FX.25 Mode to RX+TX. This will turn on forward error correction. Because forward error correction is backwards compatible with no error correction you can still send to and receive from stations without FX.25 but when a station has FX.25 enabled you both will benefit!

 .102.300 MHz USB with an audio center frequency of 1000 Hz
+If you prefer LSB then use 14.105.000 Mhz LSB with an audio center frequency of 1700 Hz. This is the same as the USB frequency above because that's how math works and packet radio doesn't care if the mark and space frequencies are "flipped."
