Pixies and the Micro-80

There has always been a call to see what can be worked with very little. Among such rigs are the Pixie and Micro-80. I have built both in the past. 

Both use the PA as the mixer on RX. The RX is the compromise although both work. Pixie kits were available as kits from China at very low cost. I bought one for 40m, with a crystal on 7.023MHz. If you get one you may want to consider crystals on 7.030MHz which is the  QRP calling frequency in Europe. These crystals are available at low cost.
