Hi all, We added AM mode to the KX2 today, both transmit and receive. Its primary purpose is for SWL (short-wave listening), i.e. copying commercial AM stations. (Remember that the KX2's sensitivity drops off rapidly below 2 MHz due to protective high-pass filtering, so it wouldn't be your first choice for AM brodcast-band DXing.)
AM transmit is far less efficient than SSB, so it would typically be used only if the target receiver can't demodulate SSB, or for special applications. For example, there's some AM activity and experimentation in the ham bands, notably around 3.870 kHz at night. I'll have to drop in with 10 watts (carrier + sidebands) and get a report :) While the KX2 was optimized for SSB, AM mode sounds fine, and of course is easier to tune than when using SSB modes with AM. In AM mode, the operator can select 1, 5, 9, or 10 kHz steps for course tuning using the VFO CRS menu entry. (Yes, some countries use 9 kHz intervals between stations.) If you're interested in testing AM mode on the KX2, please email me directly. 73, Wayne N6KR ______________________________________________________________ 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 Message delivered to [email protected]
