Half size RX crystals data (GWS?)

[plane_spotter]

Dear all, can anyone point me to a possible data sheet for half size crystals for rx's. I think some GWS units use them.

thanks

What data do you need? Since most crystals are custom made parts, I doubt you will find a spec sheet. They are most likely 3rd overtone series resonant crystals.

Hi plane spotter,

They are UM-1 size, in Australia the RX crystals are 3rd overtone AT cut 18pF load .
BlueArrow micro crystals are even smaller. They are UM-5 size with same specs.
I've used BlueArrow crystals in GWS RXes with no problem .

Google for for other specs.

Cheers
