Pixie Transceiver Kit

Posted on Updated on

Well, after many years I have built my first project! It is so long since I have done some real soldering and constructing a printed circuit board. I still have my skills and can solder as well as I could 20 years ago! This is a nice little kit, costs about £2 from China on ebay and comes with clear instructions. The PCB is double sided, but good quality. Takes a bit of deciphering of components as the capacitors have numbers that don’t relate to the values, but the instructions explain all this. One thing is that I can still remember the resistor colour code and had no problems at all identifying them. The inductors supplied seem to follow the standard colour code. a quick search on Google and I was able to identify each one.

I was really pleased with myself on completion of board, now I needed to test this. Note that all sockets are included in the kit, and also a 50 ohm dummy load resistor for testing. I connected my headphones and antenna to see if I could hear anything and WoW! I could hear CW on 7Mhz… today there was a contest, so lots of stations!  I could hear three separate CW stations on the receiver, but I found that the audio level was too much. I decided to add a small pot on the input to audio amp to turn the noise down a bit.

Now you have to realise that this receiver is as wide as a barn door and you can shift the frequency slightly with the on board pot, but still it worked! I connected a morse key to the socket to try out the transmitter….it works!  OK, it is very low power, but I was able to monitor it on my Yaesu FT450D with the 50 ohm dummy load connected. When I connected to antenna I put out a few CQ calls, but no response. I guess that you need some patience to actually work a station using the Pixie.

A nice little project which gave me lots of confidence in building again and ideal for someone about to gain their licence.
