I have TWO big DUMMIES.
........Anyone that operates an amplifier NEEDS to have a dummy load.
Yes, I would be a dummy not to.
Mine's a 25W virtue signaler. No other known use.
I would never be without one.!! They have become less popular since solid-state finals.
I have always had a dummy load with my station for tuning and diagnostic purpose, it would not be a complete station without one.
I never had one whern I had tube finals or an old soldid state rig.
Antennas usually tuned really close. Used to turn the power down to a few watts to get the swr mapped out.
Made one when I bought my IC9100 and built its power supply (tested it with my old ft757gx).
Wouldnt be with out it today, was able to test my wifi relay box to see if it changed swr.
Used it as much as the mfj antenna analyser
Was a cheap build using a hi power termination tab resistor mounted on a big heat sink
IMHO every ham should have a dummy load and a good external SWR meter for trouble shooting.
I have many. One even has a service monitor built around it.
I do, but it is built into a manual ATU that is now retired and sitting on a shelf in the shack. Since all my cabling is hidden, it would be a bit of a pain to get it into circuit, so I would need a good reason to do so.
When I did have it permanently installed, I used it fairly frequently to set up modulation levels for digital modes. These days, I tend to rely on guesswork and low power out on a band that it closed.
RTTY is 5 level code and only has CAPS.
