Re: [Elecraft] K3s using RS232 v USB?
I've had far fewer issues with rig control via serial than via USB. If there is stray RF in the shack (easy at QRO), the USB devices can 'go wonky' (more than a driver issue, requiring a complete shut down to power off, then rebooting to clear the actual USB hardware on the mobo) but serial chugs along.

Re: [Elecraft] K3s using RS232 v USB?
The only con, really, is being tied to an RF-hash producing, frantic, freezing, crashing computer if you want to operate your radio. I'm a SW developer and I have to fight those things all day, every day so that's the indelible image in my mind when trying to mix my Mac with Ham Radio - so I tend to try to avoid having to use a computer for my radio ops if I can help it. Just give me a Vibroplex and a notebook and I'm happy. Otherwise, there are no negatives to using the USB support over the RS232 that I can see. I believe both Windows and MacOS already have driver support for the internals inside the K3S, so the basics like using the K3 utility and using its audio devices within applications with sound support is pretty much plug-and-play. I believe the K3 utility worked out-of-the-box on my Mac with my K3S when I checked it over a few weeks ago. 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/K3s-using-RS232-v-USB-tp7614868p7614871.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] K3s using RS232 v USB?
Am in the process of setting up K3s and would like advice on the pro/con of using RS232 via interface (mKII) to computer or simply USB port to computer. One pro is obvious to me, such as eliminating the Hydra cable between my microHam MKII and rig. BTW, the mKII is great piece of "kit" which I have had for over 8 years, first on Orion II then K3 #250. Never an issue, always worked perfectly...kinda like an autopilot, one never thinks about what it does, until it fails. As a heavy equipment operator, B777/787 (instructor pilot) the A/P is engaged after take off and the jet flies itself (via computer inputs) to touchdown in LU land 9 hours later; a total A/P failure has never happened in those aircraft, what with redundancy, but if it did, it would be like 9 hours of operating a dxpedition with paper log and bug. As CX7TT/CW7T, made over 30k Qs in 10 years on all modes but mostly cw and RTTY. Even did 1st moon bounce with W7GJ from MT to CX. So now you have an idea of what and how I operate...throw in a little PSK and WSJT. Now, I have looked for info on Nabble so as to not invent the wheel, the K3s manual and Fred, KE7X, excellent K3s/P3 manual, Ch 10 KIO3B which shows the many variations to configure and setup. I am not an EE or electronics technician, simply an appliance operator, so I need you guys to keep it simple! I would like to know exactly what would be sacrificed by the convenience of using the USB to computer vs an external interface. So what are the con(s)? Thanks for reading. 73 Tom CX7TT, HP1/K6CT K3s #ATENN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
