How to test SSB transmitter

Not to beat a dead horse, but SGC, the manufature of a fine antenna coupler, suggests using a light bulb. I did this when I was much younger and thought it cool. But forgot all about it until I read it in the SGC-230 Antenna Tuner manual.

Go to page 38 in the manual (or page 46 in PDF reader) for more info on how to do this. Worth a try.

Actually Brian, the Icom M-802 has a power output meter/display...which is fairly accurate/linear, showing one segment for every 20 watts...
So, a "light bulb dummy load" is unnecessary...

Although, use of a florescent tube (straight or round), at the antenna base (near the lower insulator is good), does allow you to see a relative indication of how much of your transmitter's power is being coupled/transferred to the antenna....although not an exact reading, this can be used to determine whether anything has changed since your system was first installed and/or when you make changes to your system and wish to see if anything has changed/gotten better or worse...

Fair winds..
