N5AB's Mighty Midget 40


Bill & Pete,

Your recent podcast on the Michigan Mighty Mite got me excited about hooking up
the one I built a few months ago.
The wattmeter claims it’s putting out 700 mW into a dummy load.
The old crystal I’m using is 7.108 mHz

The shack receiver verifies I’m on 7.108
The receiver also says I’m very strong on 14.216
I added a low-pass filter kit (now apparently discontinued) from kitsandparts.com

Even with the filter, I’m still hearing a strong signal on 14.216.
I’m not sure what’s going on here. Perhaps the transmitter coil is radiating the harmonic I’m
hearing on the shack reciever.

You guys are putting out some great podcasts! keep up the good work.
