The Pixie Switch will switch up to 4 different crystal frequencies on your QRP rig. Kit includes the PCB, switch, and even the header and connector to install into your QRP radio. Just add your favourite crystal frequencies.
The Pixie switch was designed to do more than just switch 4 crystals. It can also be used to switch the front end crystals on radios like the Chinese Super RM Rockmite, switch different band filters, or use the extra crystal position with a capacitor or inductor to pull the crystal frequency.
