Crystals

Lott of new experience this weekend. Using my new VNWA from http://www.sdr-kits.net/

I have measured Crystals from 2 - 32 MHz. i Have 10 HC-49S and 11 HC-49U 20 MHz. This was reserved for this project. Off the around 35 pics. i measured i put one in the trashcan. the is variation of Q and Rs in the samples. but the  HC-49S @ 20 MHz has a Q of 76000 - 90000 and should be okay.

A plot from the VNWA.

Amazing SW option included in VNWA sw.

I will later in this week hopefully mount lsb and usb crystal in the modulator/de-modulator.
