Hi Robert.Here is a picture of my GPS gauge with the bezel. I'm using RE11 encoders I get form Switch Channel, www.switchchannel.com, for $1.29USD each instead of the Grayhill dual concentric encoders that cost $85USD each. I bought 2 of the Grayhill encoders, but decided to use the RE11s instead. That's what I use in my radio stack & they semm very reliable.Regards,JimForgot. Yes, we are designing an enclosure.

Simply stunning! Are the RE11s dual concentric as well? I've been asked a lot about where to find dual concentrics lately. I know the ones at Grayhill are CRAZY expensive!Robert

Yes. Very, very nice indeed.Mikewww.mikesflightdeck.com

This might be of interest to you. No idea on price but its the optical kind so its likely to be pricey.http://www.cole-switches.com/products/oe39c.html-Leo

Hi Robert. Thanks for the kind words. No the RE11s are not dual concentric. They work by pushing in the shaft. For example, in my COMM radio, I just turn the knob to adjust the MHz. Then I push in the knob, hold it in & turn to change the KHz. In my GPS, they work the same. In the GPS I emulate the push button in the Grayhill by using a momentary rocker.Regards,Jim

Yea, understandable to avoid the Grayhills for the price :)If you want to do some handwork with the switches, it's possible to do a very very nice dual concentric switch from two of those generic 12-position switches you can find cheap. The trick is, replace the 6mm plastic shaft with a 6mm metal tube and you can route another switch *through* it.I did a prototype myself and it worked out very well, then a friend improved it still using a higher quality switch for the "back" one and made it more "pro" in other ways too, since he has better tools at hand.http://tigert.gimp.org/vatsim/cockpit-stuff/knobs7.jpghttp://tigert.gimp.org/vatsim/cockpit-stuff/knobs5.pngThe pics are of a bad quality, and you can really improve the strap that holds those together, a better solution is to use something like this:

   |   __#__ ,- a metal bracket shaped like "C"|(___) < switch 1 with 6mm hollow shaft with 4mm inner diameter|  ||  |   < 4mm shaft extension|__#__  (___) < switch 2

I hope this makes it more clear and maybe this is useful for someone.Tuomas

Those are quite expensive... but are worth it to some extent. I LOVE mine, and they make the MCP much more real. Plus they are explosion proof.. lol! You only need two for the MCP, so $100 per switch may not be so bad for some.Robertwww.777Project.cjb.net

Do you have your own custom made s/w to comunicate with Fs, or FsBus? As i know this fuction is not supported in FsBus and these rotary encoders they don't send different signals when pressing the pushbutton. The rotary and the pushbutton are 2 different fuctions as i can see from specs. So i'm doing something wrong in the way i'm thinking, or you have a custom made s/w that supports this fuction. ie. when pushing the RE!!'s pushbutton you have a "flag" that tells to your s/w to change the Khz and when is not pressed change the Khz. Right?:-zhelp Eddie

Right?If I am not totally wrong with my thinking, one could route the signal wire from the encoder through the pushbutton if the pushbutton is "ON (ON)" type, meaning it has output pins for both "up" and "pressed down" position.Then you could route the encoder signal through the pushbutton, so that when you push the button down, the pushbutton switch routes the encoder bits to a different wire. At least in FSBUS the "ground" pin is shared with all switches AFAIR.Tuomas

We wrote software drives our panel, radio stack & electrical panel. Unfortunately, I can't give it to you as I'm beta testing it for a commercial company. I thought that maybe Mike or one of the other talented electronics guys could help you with the circuitry. I just introduced them because they are so inexpensive.Sorry,Jim
