>>>Just what is "the big deal" about pushing a single
button instead of pushing two buttons in sequence to get to the band and mode you want? <<< Hey Doug - You hit the nail on the head, contestors have the optimal solution with the stock K3. But "modest stations", what I'll call condo class or dipole class (like my own) require a scan of the available bands to see which -one- you can use on a given day. There is a fair amount of back and forth in determining which band to call home for a couple hours. With single touch band changes, you press one button (example 20m), twirl the main tuning knob, take a reading, okay now hit the next band up (15m), twirl, okay how about 10m? Nope, MUF not there, back to 15m. Your finger remembers single press bands, even between weekends (many of us work). Now imagine sitting down on Saturday morning after last operation a week ago - okay, hmmm, which button oh yeah - M->V, okay now which band is button 20m? Hmmm think it's 1. Two button press and you are there. Repeat 3 times as in example. Summary - one button is enough for even a finger to remember for a week. Multiple keypresses, in addition to requiring extra time to accomplish, require the user "boot the brain" before the action gets accomplished. Hard to put into words Doug, but if you were there it would be plain as day! c u Don --- DOUGLAS ZWIEBEL <[hidden email]> wrote: > Hi Don, > > I am genuinely curious.

Or you can just use an up/down and get done the working up the bands and
scanning with the dial... Hell our forefathers had to tune up for quite some time to change bands. Now we've reached the point where using and up/down button set is too slow for us. Then god forbid we actually have to engage our brain and remember what band we have saved where. If its so hard put a band plan on the wall and just write a number next to each one in order. Then you can walk through them that way. But oh my gosh we have to press two buttons to get to each band.... If you're a condo/dipole class why not sit back and enjoy it. Maybe cut your QSO shorter by 3 seconds so you can get in those extra button presses for band changes. Maybe you can head to a fast food place and have them make you a meal that you can eat in the car without having to ever stop or get out. That should save you enough time for a few extra button presses to change bands. Personally I like the portability that a smaller/lighter rig affords me. Thankfully the K1, KX1, K2, and K3 pretty much all fit into that category. I don't think I'm alone in this though.... There has to be a reason why the IC706 is the best selling rig in the hobby and it has band up/dn buttons. Not that I own one though...

Idea.... Why not make an additional set of control buttons and use the "secret" connector on the bottom right side of the K3. Just a small panel that would fit under the K3 and would give you numerous programmable buttons. Then, you could set up the button on the little add on panel. Or, for quick band changes in a contest....I use N1MM logger and just change bands and modes through software. Or, a stand alone PIC processor on the RS232 port that does the same thing as software in a computer. There are a lot of people who like to "market" add-ons to the Elecraft products that just work great. Fingerdimple, LP-PAN, etc...

These ideas make much more sense than trying to remap front panel
buttons.

I don't see how all this band button talk is going to make any difference
with the K3. The panel is the way it is and I doubt that they can economically change things. Maybe in the future, when K3 sales drop off, they will come up with a new package for the K3 boards that would incorporate a panadapter and slots for transverters and all the buttons you could want. It would be nice if we could use our existing electronics in a bigger package, for those so inclined to upgrade. I think Elecraft chose a layout very similar to the TS-570 which was very functional. Some people are impressed with the obsessive amount of controls on a FT-2000 or the fewer ones of the IC706. I think Elecraft found a sound medium. I own both of those and find the K3 easiest to use. Some people don't think they are getting their money's worth unless there is a big cabinet. Take a look at all the dead space inside an Orion II cabinet. Now if I could just find something new and useful to do with my unsused K2 sitting on the shelf.

Agreed... I get a bit too wound up about it as it would frustrate me if
I was the designer. I've been very happy wtih Wayne's prior priority structure and I'm sure it'll continue that way in the future. The one I'm still interested in playing with is the DVR. It'll probably be mostly a wowgit factor for me as I don't do a lot of SSB but it'll be my favorite thing in the world for FD.

Heck I was impressed at how open and clean it was inside the K3. Then I
saw the pictures of the sub RX and was impressed at how shoehorned in there it all was... Find it pretty impressive that they even had enough room to add the extra sub RX shielding as an afterthoght too! Maybe they were already planning for it as a possibility but when they were cranking out the SubRX it seemed like it was something they had to add to increase isolation between the two receivers. ~Brett (KC7OTG) On Sat, 2008-07-26 at 13:32 -0400, Mike Penkas wrote: > I don't see how all this band button talk is going to make any difference > with the K3.

G'day,
I don't recall all this anguish about the layout of the K2 front panel. Why can't we just accept that it is as it is and get a life and get on with better things. I'm sure there is no way it's going to redesigned to suit individual whimsy. I for one am utterly sick of hearing about it. Now where is my KRX3? When I receive it I can drop off this infuriating Zoo.

Ron, Thank you very much for the information. I usually work tethered to
ground with a wrist strap but also need to acquire a mat. Since my K3 will be factory built, I won't rush it for now. My environment typically is 60% humidity... sometimes higher... my shop/shack is in the basement. When I start to smell mold I turn on the Dehumidifiers. Air conditioning is available but the who needs that when the temp is 65! 72, Bill K9YEQ K2 #35, K2 # 5279, KX1 #35, Mini Modules, etc. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Ron D'Eau Claire Sent: Saturday, July 26, 2008 11:51 AM To: [hidden email] Subject: [Elecraft] ESD Safety This is a subject that comes up here regularly among those working on their Elecraft (and other) rigs.

I have two K2's and use the lower power one to irritate the QRO boys on 75.
They think I should add more power. I think they should get better receivers! 72, Bill K9YEQ K2 #35, K2 # 5279, KX1 #35, Mini Modules, etc. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Mike Penkas Sent: Saturday, July 26, 2008 12:32 PM To: [hidden email]; [hidden email] Cc: Elecraft Discussion List Subject: Re: [Elecraft] RE: Band Button Gripe I don't see how all this band button talk is going to make any difference with the K3. The panel is the way it is and I doubt that they can economically change things. Maybe in the future, when K3 sales drop off, they will come up with a new package for the K3 boards that would incorporate a panadapter and slots for transverters and all the buttons you could want. It would be nice if we could use our existing electronics in a bigger package, for those so inclined to upgrade. I think Elecraft chose a layout very similar to the TS-570 which was very functional. Some people are impressed with the obsessive amount of controls on a FT-2000 or the fewer ones of the IC706. I think Elecraft found a sound medium. I own both of those and find the K3 easiest to use. Some people don't think they are getting their money's worth unless there is a big cabinet. Take a look at all the dead space inside an Orion II cabinet. Now if I could just find something new and useful to do with my unsused K2 sitting on the shelf.
