On a good day, the signal from the CB itself could do that. The A Number One problem with those CB linears is that most of them were designed badly, and radiate out of band. Unforch, the FCC is so utterly incompetent (remember, FCC director is a patronage position) that they won't do anything about it. To this day, the US is the only developed nation that does not have an amateur longwave band.tcmtech, people that use boosters like that are the bane of hams the world over. On a good day, the reflections from that will travel across the entire globe and bleed out lower power local transmitters. And please don't say the solution is for the local guys to get more powerful transmitters =)
I was going to suggest that but what happens if your scope isn't up to the job, i.e. the highest it can go is 2MHz?oscilloscope and 50 ohm dummy load, and calculate E²/R. any method not using a dummy load is most likely illegal and may end with a friendly visit from the men in bad suits asking for a $10,000.00 donation.
I think the Internet did a better job of killing amateur radio than CFLs or anything else.Those killed the radio amateur activity. And no entity has moved a finger about it.-
