81. [AMPS] High-SWR protection (score: 1)
Author: n4zr@contesting.com (Pete Smith)
Date: Sun, 29 Oct 2000 14:02:09 -0500
The RF Applications VFD wattmeter, though not inexpensive itself, has an inexpensive option for unkeying the amplifier as soon as it senses SWR above an adjustable limit. The company also makes (or a

Thank you, Peter! At last the discussion moves forward. Given how long any given TL-922 may have been around, it seems entirely plausible to me that the suppressor resistors would have changed value

Amen. Mine doesn't have THAT problem, but the trigger switch has been flakey since it came out of the shrinkwrap, and it's very slow to heat up. My Weller 8200 140-watt iron is much better for PL-259

This is a real simple question, I suspect. When I operate my SB-220 into a dummy load on 40M, the loading capacitor is at approximately mid-scale. The dummy, a cantenna, measures about 1.04 SWR on my

Yes, indeed. Can any of the Collins aficionados out there affirm just how the 30S1/30L1 "tune" system works? I can remember tuning a 30L1 by the book, and being told to dip with the Tune cap and then

Jim, I'd wait. The VFD is definitely worth it. It's simply wonderful to be able to tune your amp with a string of dots, have the wattmeter follow it, and all with the ergonomic ease of the led bar gr

It puzzles me that we don't seem more of these problems with remote antenna switches, where you're receiving through contacts that must also be able to handle transmitting power. 73, Pete Smith N4ZR

Sure, and in this case the original indicated input SWR was more like 1.5:1 than 1:1, hence the length of feedline mattered. I'd still like to know why a higher indicated SWR (on the TS-930) translat
