QP-21 is a CW kit transmitter by MIZUHO company famous in Japan. I began my amateur-activity with this QP-21 transmitter. After half a year from beginning, I add the VXO and power AMP for QP-21.

It covers from 21 to 21.4MHz. It stabilizes in 3 minutes. Good for CW or SSB. If you want more, just add a Huff-Puff or a FLL. Proper for DC radios on 15m CW or DSB.
