I need to order a new heterodyne oscillator crystal for the 28.5-29.0 mhz
portion of the 10 meter band. Peterson crystal needs to know if it's a
series or 20pf crystal. I have no idea. Can anyone help with this?
WY3D.

Do you have the schematic? If you do, scan the oscillator circuit at
300 DPI. Crop out everything else, and convert it to a B&W GIF or JPEG
file so it is a small file, and e-mail it to them.
