MFJ makes something called the MFJ 1026 noise remover, that allegedly can remove or reduce QRM from a specific source by phase shifting and mixing the signals from your main antenna and an extra receive antenna. Details here: http://www.eham.net/reviews/detail/1205
I wonder if the K3 with the subreceiver could be made to do something similar, the architecture would probably not allow it because the DSP from the subreceiver and the main receiver aren't connected, but it would sure be a great thing to have. At my QTH we suffer from daily QRM on 40m, which starts around 2000z and is usually gone by 2315z, putting S7 noise all over the 40m band, I haven't been able to track it down yet but myself and several other hams are looking at it (it's affecting an area of many square miles, including the entire area surrounding Cambridge). If there was a way to do something similar directly in the K3, perhaps with a new add-on module, that would be fantastic. I realize the chances are slim, but here's throwing the idea into the air! 73, Thomas M0TRN (K3 #4208, KX3 on order) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
