Has anyone tried REALLY extending the cable between the K2 and the KAT-2? I
would like to separate mine by 20 or 30 feet. What I want to do is get the KAT-2 and all the antenna conectors off of my oprating table, and close to the exit point of the shack. I have heard the main concerns are noise (pickup and radiation) and timing. It would seem that using optical converters and optical cable might take care of both. Any thoughts?? 73, Tom, KG3V ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
Tom,
Pulse shaping as well as 'turnaround time' on the AUXBUS signal is important. Extra cable length adds to the capacitance and will round over the shape of the data pulses. Your proposed solution for using optical converters and cable may be a potential solution, but as far as I know has not been tested. You are certainly welcome to try it, and if you do, I would encourage you to share your results. I would be particularly interested in any data you could find on data distortion and delay times through such a system. 73, Don W3FPR [hidden email] wrote: > Has anyone tried REALLY extending the cable between the K2 and the KAT-2?

Thanks Don
I guess this might have seemed like a good April fools joke, but actually, they do this with many other wire type interfaces. This includes Ethernet and RS-232. So if the drivers are fiber are affordable, I think it could be done. If anyone has any data of the required rise times or prop delays between the devices, plese let me know. I may try something along this line. Tom, KG3V On Apr 3, 2009 10:37am, Don Wilhelm <[hidden email]> wrote: > Tom, > Pulse shaping as well as 'turnaround time' on the AUXBUS signal is > important.
