Re: Daylight Radio: Crystals?

Hello Steve,
that is the approach that a lot of us are using. by building it on boards one block at a time, it seems to make trouble shooting and testing of sections much easier. Good luck on your project.

I¡¯ve a 3D printer at home in the U.K. and, if the designs are available, I¡¯d be happy to print parts for the permeability tuner for fellow builders. I¡¯m not sure how practical is is to ship things outside the U.K. though.?

I'm gathering parts to build a Daylight Radio. What are the critical specs for the 5 MHz crystals? Capacitance, etc? How critical?
Thanks & 73....?????? Mark???? AA7TA
