Thanks for all the info! It turns out I have an RSP2 and now have it running with HDSDR in "slow" waterfall mode. I'm now looking for a way to control the front end options of the RSP2 - nothing seems to be built into HDSDR to do that, but that's a topic for another mail list. BTW - I conveniently have an EXCELLENT Clifton Labs 1800 KHz AMBC high pass filter that sure tames the input dynamic range when measuring 160M.
I will also try the suggestions for different ways to record signal strength on the K3. Thanks again, Rick N1RM -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Using-K3-for-relative-noise-survey-tp7632955p7632979.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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]
