I'd like to see some specs for the P3 to know that it really has the sensitivity to do this. The IF OUT mod regains ~10 dB of the signal lost in the original design but I believe that still leaves ~7 dB that may be lost, according to Jack Smith's measurements: http://cliftonlaboratories.com/elecraft_k3_and_panadapters.htm#What_then_is_the_transfer_gain_of_the_K3_ 73, Bill -- View this message in context: http://n2.nabble.com/P3-tp4576865p4580749.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
