If you have never used a panadapter you are in for hours of amusement: I am just looking/listening with PSDR/IF on 40m to a remote control ssb station (appropriately based in a city renowned for wind) whose spectrum below 200Hz is peaking 15dB higher than the rest of his signal. Integrate the area under the curve and you can approximate that at *least* half of his power is useful communication only for whales ;-)
And at other times when you heard spitch you will be able to see the imd christmas tree 40kHz away that is causing it. Probably with 'ALC' ;-) You may also get a surprise with wobbly signals out either side of your passband (hopefully) on an empty band. Switched mode PSUs are the devil's work :-( Have fun, Pete F5VNB ______________________________________________________________ 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
