REMINDER: Please be careful on how you adjust your OUTPUT volume on your soundcard/interface to your transmitter. If you have the volume too high, you will cause the audio to be distorted, leading to the transmission of spurs and 'garbage', which causes interference. Here is a list of common JT65A frequencies: Freq kHz / Sideband / Note Also, be sure that there is no RF getting back into the audio chain, and the transmitted signal, as this causes the same problem: spurs and interference. * Note 1 * Do not use 10145-10150kHz because JT65A is NOT COMPATIBLE with PSK31, MFSK, or RTTY and the other fast time-sharing modes such as PACTOR, ALE, PSKmail, and APRS. * Note 2 * It is becoming a standard practice on 30m to actually use 101378 kHz as the window frequency (USB), to play 'nice' with WSPR stations. This, of course, is an issue with certain countries/regions where digital operation is not allowed below 10140 kHz.
