Larry: Although some claim this works, I wouldnt risk it.
I operate #3192 with a microKEYER2 and I dont like plugging and unplugging either. I purchased one of these: http://www.amazon.com/Switch-Manual-Serial-Position-CCS11200/dp/B000TTWZTQ/ref=sr_1_1?s=electronics&ie=UTF8&qid=1276712533&sr=1-1 I built several cables using one long serial cable I had on hand and some DB-9 sockets and plugs. Or you can buy pre-made cables (see www.winford.com for all the varieties). I wired a cable from the common port of the switch to the K3 serial input. I plugged the MicroKeyer's serial output into side A and my "real" serial port from my computer through a serial cable into port B. When I want to upload software or change a setting using K3-EZ or the Utility, I turn the switch to B. When I want to use CAT using the MicroKeyer, I turn the switch to A. microKEYER is very tolerant of this shenaniganz, you can "hot switch" it in and out. RX Freq will flash with underscores when its not online, as soon as you switch back to it, it figures things out and youre back to where you were. Simple, inexpensive, and has never failed me. The switch also makes a nice riser stand for my Autek WM-1 wattmeter, bringing it level with the top of both my K3 and my Kenwood TS570D second radio. Its cheap! Why risk issues? Plus you get yet another knob to twirl (hams like twriling knobs, eh?) -lu -W4LT- K3 #3192 -------------------- Date: Tue, 15 Jun 2010 19:16:10 -0400 From: "Larry - K2GN" <k...@comcast.net> Subject: To: "Elecraft - K3" <elecraft@mailman.qth.net> Message-ID: <00aa01cb0ce0$bdb7d460$39277d...@net> Content-Type: text/plain; charset="us-ascii" Is there a safe way to update a K3 through the microHAM router? I don't like moving the cables for every update. Something is going to wear out or break. Difficult to do it with my 1 good hand . Can I put a "Y" adaptor on the RS232 and run a USB to my laptop, and leave the microHAM powered off? Laptop isn't connected to the radios at all. I just need an easier way to stay up to date. Same with using the K3 EZ and K3 Util programs. Any ideas are greatly appreciated. de K2GN - Larry - http://k2gn.com <http://k2gn.com/> K3 S/N - 3278 P3 S/N - ????
