I assume the Elecraft unit has a pad to get the level down to sub nanowatt levels? Why not remove or change the pads. There are a fair number of inexpensive quiet oscillators out there. If you aren't concerned about frequency accuracy, then any of the inexpensive low jitter clock oscillator modules would work. You can follow it with a pad, a LC BPF, and a pad. Minicircuits sells inexpensive IF filters for, e.g. 10.7 MHz, and they do quite nicely for removing harmonics from a 10MHz source. If you want good frequency accuracy, low phase noise, and a bunch of power, what about a 10 MHz OCXO from someone like Wenzel or surplus HP/Agilent unit. _______________________________________________ FlexRadio mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
