Fired up the 7300 after dinner and, in the CW mode, it takes about 16 turns to sweep 100 KHz, or 6 KHz per step. There is no down arrowhead indicator over the KHz portion of the readout. Touching it turns the arrowhead indicator on and the tuning rate increases to 1 KHZ. Touching it again turns off the indicator and the tuning step drops back to where it was. If the radio is in the AM mode, the indicator is on and the tuning rate is 1 KHz. The Tuning Function is explained on Page 3-3 of the printed manual. Other tuning parameters can be set by pressing the MENU button and selecting the SET > FUNCTION. See page 8-4 in the printed manual.
