IMHO it would be neat to have a 'dynamic' tuning rate. You start with what you selected by the existing buttons (fine/course/rate...). If the system would monitor your 'speed' while turning the knob it would be possible to increase the speed if you keep turning (how much to ramp up ... TBD). This way the system would react to your 'wishes'. After a defined inactivity time the system will fallback to the manually selected value. That's it (sorry Wayne... ) 73 Thomas, DM7TN -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of [hidden email] Sent: Wednesday, May 07, 2008 8:20 PM To: [hidden email] Subject: Re: [Elecraft] K3 Band switch On Wed, 07 May 2008 10:51:42 -0400, Don W3FPR wrote: >Ron, > > >A "stack" can only be loaded/unloaded from one end (usually referred to >as the top) and one must sequentially remove entries until the one >wanted is present.

I wonder if it would be useful to implement a Very-Coarse tuning rate, say 5 MHz per full turn of the VFO knob. That would be your band switch. With such a rate you could quickly get to any band, ham or SWL or whatever. However, if you should select a ham band with this coarse tune VFO, it would automatically recall your previous settings for that band (same as the Band buttons work) It could be accessed by holding "Coarse" while turning the VFO knob. Perhaps this could be managed with one hand? [OK, I don't have a K3 and haven't read much of the manual, so probably shouldn't be making comments at all. The above is just a suggestion. If it isn't a useful one just ignore it; I'm not really looking for any feedback on it.] 73, Drew AF2Z _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Each to his own - I have a Yaesu FT-847 with the 'shuttle' ring which
does dynamic tuning similar to that, and I hate it. By the time I get it near the frequency I want, it scoots off to somewhere well beyond the mark. I just can't get the 'feel' for that rapid tuning (yes, it does tune slowly near the center and quite rapidly at the extremes, but I just can't seem to get my hand and brain coordinated to make it work decently. Your mileage may vary. 73, Don W3FPR Thomas Norff wrote: > IMHO it would be neat to have a 'dynamic' tuning rate. > > You start with what you selected by the existing buttons > (fine/course/rate...). > If the system would monitor your 'speed' while turning the knob it would be > possible to increase the speed > if you keep turning (how much to ramp up ...

I originally suggested the [VFO dial + HOLD COARSE] combination to do
the 1 MHz stepping because I thought it might be easy to do with just one hand. Not having a K3 in front of me yet, I don't know if that is so. Anyhow, in general I prefer knob turning to button pushing, given a choice (analog vs digital, so to speak...) Ok," what success do you expect in hitting 10.101..." Say you're on 6.035: You hold COARSE while turning the VFO; the display changes to 7.035, then 8.035, then 9.035, then 10.035 (about half a turn in all, at the 5 MHZ/turn rate); you then let up on the COARSE button and tune the VFO normally to 10.101 where, having entered the 30m band limits, your settings for this band are restored. The Band+ and Band- are fine for ham band switching. But for general coverage navigation a real band switch, as above, would be preferable. Now, you have complained about having to button-push through every intermediate band to get to a desired ham band. Could this be alleviated somewhat using the VFO knob as a ham band only switch? Say, by holding the FINE button you could step through the ham bands using the VFO knob, perhaps more conveniently than "PUSH PUSH PUSH...", In other words, map the ham bands to VFO knob rotation while the FINE button is being held. Anyhow, these are just suggestions, not necessarily feature requests. My only request is to get my K3 (few more weeks!) 73, Drew AF2Z On Wed, 07 May 2008 21:01:15 +0000, Brian/K3KO wrote: >Augie, > >And what success do you expect in hitting 10.101 or 18.068? > >Unfortunately the ham bands don't all start with .000 lower limits. > >What is really needed is one button press to get to the band you want. >Two to six button presses alone or in combo with knob twisting simply >isn't acceptable. >Standing on your head while twisting a knob behind one's back isn't either. > >73 de Brian/K3KO > >Augie Hansen wrote: > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The same button is used for FINE (tap) and COARSE (hold), therefore you can't "hold" FINE. 73, Gus Hansen KB0YH _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The Sangean 803A (and other brandings of the same hardware), a consumer SWL receiver with SSB capability, does it and it has been common in mouse and trackball drivers for three or so decades. -- David Woolley Emails are not formal business letters, whatever businesses may want.

The K2 (current firmware) defers any internal relay switching until about 0.5 seconds after the last band switch press. If the K3 doesn't already do it, couldn't it defer sending any signals that would normally cause external switching in the same way? -- David Woolley Emails are not formal business letters, whatever businesses may want.

I use a KRC2 to control antenna relays and they do not start to clack until I stop pushing the band button. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
