I use 500 or 1000 Hz step size for regular phone operation. A 100 Hz step size for phone during a contest. My hit rate is 99% unless the operator has a radio that is off frequency.
Most people who have problems with click tuning are not tuning to the correct part of the wave for (where the suppressed carrier would be for SSB) and have the steps size too large. Interesting conversation on "spin tuning". I truly find that a waste of time and motion now that I have a lab grade RF spectrum analyzer (Panadapter) for a radio and an interactive way of tuning dead on a frequency with ClickTuning within the Panadapter. I am not saying "spin tuning" is bad, just not my preference anymore. The mouse is more precise and results in a lot less computational overhead to make large jumps in frequency. -Tim -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Duane - N9DG Sent: Thursday, July 02, 2009 2:29 PM To: Brian Lloyd; N4PY2 Cc: flexradio@flex-radio.biz Subject: Re: [Flexradio] Mouse vs. knob vs. tune step size - WAS: Speaker set-up Would be curious what the typical tune step size folks are running in PowerSDR? I typically run at either 1 or . 5 kHz step size. It is coarse enough that when I click on the appropriate edge of a SSB signal that I see I will hit it dead on 95% of the time. And for CW right on top of it. Occasionally I need to mouse wheel a step or two. So do many use the finer step sizes normally? Or the coarser ones like I do? The reason I ask it makes me wonder if those who find point and click tuning "unfriendly" are also the same ones who run fine sized tuning steps. Mostly just a curiosity.. On knob radios I find the extremely slow tunning rates choices/settings very annoying, takes forever to tune a signal in. In that regard I always like the older analog VFO's that were in the ~20 kHz per revolution rage.
