30m W5OLF WSPR VCXO-AXE beacon kit (2)
Our little girl was at grandma's house between Christmas and New Years eve. So, we had a couple of quiet days. Ideal to build a project like this. First of all I had to solder te small VCXO, the most difficult part to solder as it has no normal connections. It took me a while and after I thought it was allright I checked the connections with a magnifying glass. It looked ok so I continued with the resistors, capacitors and transistors. Jay provided a excellent step-to-tep description for the kit and I had no problems to assemble. Then I had to wind my first torroid ever. 29 turns on a small ring, a very small ring and very thin wire for my big hands. As you can see on the photos the ring is even smaller as the picture of Jay's description. Actually it didn't give me trouble at all, the picture of it in the manual how to count the windings is very clear. I didn't solder the power connector but attached a supply lead directly. Now it is time for the most exciting moment, does it work?
