I am a newbie when it comes to the digital modes and the KX3. The following question may, therefore, be naive.
I have been experimenting using my Tentec transceiver to copy and send APRS PSK63 beacons on 30 meters using the "APRS Messenger" software. It seems to work fine using a Signalink USB sound card with the program set for 2100Hz tones. I am tuned to 10.147.6 USB. I want to try using the KX3 in PSK63 D mode to do the same thing, but don't know what tone/shift the internal modem uses, so don't know what frequency to tune the radio to. To quote WA8LMF: "The actual transmitted RF frequency is the indicated suppressed carrier frequency (i.e. "dial frequency") plus the audio tone frequency (USB) -or- the suppressed carrier frequency minus the audio tone frequency (LSB). The actual dial frequency you want WILL DEPEND ON THE SIDEBAND YOU CHOOSE (either one will work) --AND-- ON THE PARTICULAR AUDIO TONE FREQUENCY produced by the PSK program." Up until now I have been using AFSK in USB mode to do these experiments, and don't know how that translates when using a "direct" PSK63 mode. How should I tune the KX3 to be spot on to the single RF frequency for 30-meter PSK63 APRS operation, which is 10.149.700 MHz? Any advice appreciated. -Scott N3SW- ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
