The 5 khz tuning steps are awfully touchy, even at the lowest VFO rate (100 counts per turn). That's 500 Khz per only one turn of the knob-- practically a complete "band". That is just too coarse for comfortable tuning. A little nudge and you've flown by 10 or 15 Khz. The tuning steps for AM don't make any practical sense. FINE gives you 1 and 10 Hz, COARSE takes a huge jump to 5 KHz. Shouldn't there be something between 10 Hz and 5 KHz? Seems like 100 Hz and/or 1 Khz should be in there somewhere. (Unless I've missed something here...) 73, Drew AF2Z _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
