Re: [Elecraft] K2/KIO2 with newer Palm... IR?
Sadly, the Bluetooth serial port adapters all seem to require 45 mA to 50 mA -- I checked several manufacturers. OK for the shack, not so good for PDA or field use :-( OTOH, there are tons of USB Bluetooth dongles that sell for under $20 -- even without rebates! :-) Go with the KISS principle... I just use the sync cradle with a null modem adapter to the K2io cable. It allows about 6 feet of freedom if not more and the cradle is a nice angle to read/write/graffitti. see pic at;http://users.erols.com/tjmc/k2palm.jpg BTW, the older Palms ( like the 105 are dirt cheap ) run on AAA's so it's not prob with recharging. all best Tom aa2vk ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2/KIO2 with newer Palm... IR?
OK, there has been several inquiries about this, so let me follow up on my own reply. Let's assume that we can solve the protocol stack issues and somehow make the IR connection work between the Palm (or any laptop) and the K2. You then have the problem of the very narrow beamwidth and short distance of the IrDA IR optics. This means you have to keep the Palm/laptop and K2 aligned perfectly to maintain communications. This is a major pain! We are hams, radio types, so why not a better approach. My amateur astronomy friends have pointed out an interesting device from a Santa Cruz company called AirCable (http://www.aircable.net/). This is a BlueTooth device that provides a serial port that could be plugged into the K2 and communicate with a BlueTooth-enabled Palm or laptop. Other similar devices are coming onto the market at this point also. So, why put up with the hassles that IR brings when we can move to RF using technologies such as BlueTooth or ZigBee, and be able to move around at will?

RFM modules, which don't have protocol stacks and error correction, have the advantage of needing very tiny currents. Hmmm, maybe a 6-pin PIC plus an RFM module and we'd be able to create a transsparent, low-current, reasonable performance wireless link...

Re: [Elecraft] K2/KIO2 with newer Palm... IR?
The aircable serial null modem looks nice, but it's $138 for the pair and they both require power supplies, with wall warts pictured, so it doesn't like like something I will be ordering right away. I have thought of something similar for the T1 and FT-817 though and will put it in another thread.
