I haven't seen much here on the subject so I thought I would share my experience from this past weekend in the RTTY Roundup.
We recently upgraded our multi-radio setup with two new K3S-es. Both were operated in FSK-D mode, one at the 2125/2295 tones, and the other at 1445/1615. (That helps me sort them out in the headphones quicker.) Both rigs get the FSK via the ACC port. One rig gets FSK via a Microham box, the other by FSK cables with level shifters built by me. I use Writelog as my contest logger in the mode that allows the K3 and K3S sub Rx to appear as a second radio. The K3S-es were connected via the USB interface. I used the K3S internal sound card on both rigs. And the P3s were connected accordingly with the special cable. I have to say that - other than that one weirdness with the VFO B cursor I posted about the other day - everything ran flawlessly. The internal sound card decoded at least as well as my external cards do. One thing I especially had my eye on was interference between the stations. We run full power and we have experienced wideband interference between 20/40 and 40/80 RTTY that no amount of filtering seemed to conquer. I'm happy to report that the interference is substantially reduced with the new KSYN3A on board. I used to have to pick my transmitting spots very carefully to avoid "bad zones" but now it is almost a non issue. (Woo hoo!) Also, and this of course is subjective, but QRM from neighboring stations also seemed to be substantially reduced. At least, I didn't have to QSY as much as I usually do to get away from someone's gudge. I'll have a better sense for this after a few more events. 73 jeff wk6i -- Jeff Stai ~ wk6i.j...@gmail.com Twisted Oak Winery ~ http://www.twistedoak.com/ Facebook ~ http://www.facebook.com/twistedoak ______________________________________________________________ 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
