Review on 📻 LJJDSLYU S-Pixie HAM Transceiver Radio Shortwave Telegraph 40m Super CW QRP 7.023 MHz DIY Kit with Shell & Large Potentiometer by Jenna Willis

The kit worked very well although I don't recommend it as a project for beginners. More importantly, the S-Pixie emits a carrier when a key is pressed, and the frequency of that carrier changes depending on the potentiometer setting. The attached photos show the signal on the SDR spectrum analyzer (this can also be seen on my large Yaesu rig). When the pot is turned fully counterclockwise, the signal is at 7.0240 MHz. When the potentiometer is turned fully clockwise, the carrier of the key down is 7.0228 (which is also the frequency of the key down signal). The difference between pressed and pressed button is only 12 dB. So I don't want to broadcast it; and when I do it's just clockwise with the pot full. I have to say that I have a lot of kit building experience (starting with Heathkits when I was 8 years old, almost 50 years ago). I also tested each part before soldering and the only real anomaly was L2, a 100uH inductor reading 86uH. Everything else was almost there. One final note: at 13.8 VDC I measured 4.9 mW of output power.
