The Chinese Pixie QRP transceiver kit is incredibly cheap. Of course, you get what you pay for. The kit comes with a crystal for 7.023 MHz, which is in the Extra Class portion of the band, and the receiver (if you can call it that) is incredibly wide.
In this video, VK3YE, shows how to make it “less appalling.” He shows how to add crystal and ceramic resonator VXO circuits to allow you to tune the transceiver and to allow you to receive SSB signals as well.
