What is the typical ERP of the stateside stations we hear on or around 6900?
Just curious if anyone knows

Maybe an idea - to check out the stations eQSL cards?

( topic "QSLs Received" )

Sometimes (Pirate-/Free-) Radio stations put this information
on their eQSL cards - !!!

That really varies with each stations. Solid state TX's typically are 25W carrier for AM and 100W PEP for SSB. Much of the tube gear can be from 40W to 150W carrier. Then, you have stations with either homebrew, or modified broadcasting gear, (Like Radio Metallica.), that claimed 10KW. And then, you also have small, homebrew, TX's like the famed Grenade that put out around a 10W carrier. So, it varies with every station.
The best two statements of advice that I've ever gotten are from my brother-in-law in the early 1990's. 1st one, when I bought a used '89 Olds Cutless, my bro-in-law said, "Congratulations!!! You've just bought a deficit!". The other, was on a work environment, " No matter where you go, it's going to be f***'ed -up!". No truer words have been spoken.

thanks for both the responses. I checked the qsl thread and the equipment thread and learned some info.
Varies a lot like amateur radio, it appears.
thanks again
Happy listening

10-40W (carrier) is fine for NVIS, but for F layer you need 100W+. I've never heard any of my test transmissions outside of EU using 40W. Soon as I fired up 100W using the same antenna I got numerous stateside reports. I'm in th' UK btw.
