Ok so for an experiment I plugged my 7 watt 40M radio into this SWR meter I just bought. Radio to SWR meter is through a proper cable. But to see how much impedence changes matter I set up what you see. A test lead into the u239 and then alligator clip to BNC, first with ground from barrel to barrel then from barrel to that little metal rod that stick out.
All that happens when I hit transmit when set to 10W range and REF switch is a small jump on the right side dial then the needles sit on the bottom, and when the switch is set to PWR the right needle jumps all the way to the end then they sit on the bottom.
Shouldn't I get some sort of reading?
Whats the purpose of the little rod that screws into the SWR meter, I thought it was for a clip on ground. I have never used this meter before so I don't know about it, it was 22.00 News off walmart.com (didn't realize it came from walmart).
Whit cable goes about 50' to a 11:1or 9:1 balun then to a 60some foot long wire that I have been using as an antenna that seems to have been working so far. The radio last I checked was putting out a good signal when I used a separate SDR and antenna to look at its signal.
