Yep, bought a bunch of stuff, mostly a few tubes and someone had a bunch of 7 pin male tube plugs. They looked to be tube bases that were never used to make tubes. And the grid dip meter works!
Wonder if I can use it to test antennas, to find out the resonant freq?
Supposedly, a small coil to act as a coupler on the end of the coax cable that feeds the antenna under test can tell you the resonant frequency with the grid dip meter. But I see a lot of dips on the 2 meter antenna, one every 4 or so MHz from 120 to 250 or so MHz. Not sure what I'm really seeing, maybe a mismatch at the antenna causing reflections to make the extra dips?
