Load Dummy

what is the difference of 10 meters 20 meters in radios, etc. cb radios and ham?

demand a lot of jargon cb, dummy load, all different types of radios in my question.

Daniel K is right on the frequencies, but if you use the calculator, the numbers will come out a bit off. For example, the formula is 300,000 / frequency in kilohertz, 300 000 / 28 000 is 10.7 meters, not ten, which is 300000/30000, of course. Group names are essentially an agreement, it may have been at one time, only 10 yards went through 30 MHz, but I was a ham 41 years and I do not remember. If you use tables tape, as I join here, you will remember them. A dummy load will actually be a signal, but not quite. When I think of Transmit, I do think that putting a signal will be heard somewhere and it's not as likely with a load fictitious. That's why they were created, really, so much power over the tests could be done without risk to release a signal that will interfere with others. Most modern transceivers are solid state and are implemented only if the SWR is too high, as you could get in a "no load, it will shut down the transceiver to avoid damaging the final phase, which is what will blow if you try to transmit without an appropriate charge.
