One other point to note about this: In AM and FM, the frequency displayed on the K3's dial is, of course, the carrier frequency, and the modulation sidebands will be on both sides of the carrier in the waterfall.
In USB and LSB, the frequency that is displayed on the K3's dial is the BFO or suppressed carrier frequency. In USB, everything you hear at audio will be above this frequency, i.e. to the right in the waterfall. In LSB, everything you hear at audio will be below the dial frequency. Which side they are on in the waterfall depends on whether the waterfall is arranged from left to right with increasing audio pitch or with increasing radio frequency - in LSB they run in opposite directions. In CW, however, the K3 does not display the BFO frequency. The frequency that appears on the dial is the actual frequency you transmit on, which is lower than the BFO frequency by your chosen sidetone pitch (CW on the K3 uses the lower sideband). Higher frequency signals will be at lower audio pitches than your sidetone, and lower frequency signals will be at higher audio pitches. If you prefer, you can put the radio in CW-REV, which is upper sideband. In data modes, it's a bit of a mixture. DATA A is just like USB: the frequency display is the BFO frequency, and everything you hear is at higher frequencies (to the right in the waterfall). AFSK A and FSK D are more like CW. They are both on the lower sideband, and the frequency in the display is the actual transmitted Mark frequency, not the BFO frequency. You can choose one of four different values for this using the PITCH control. PSK D is upper sideband, and the displayed frequency is the actual transmitted frequency, which is at 1010 Hz audio. 73, Rich VE3KI _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
