    This might be a dumb question.
    on 80m a person with one kilowatt transmits in the same town and is 60 plus will something bad happen to my radio.

    No.
    I run the Alaska Statewide saturday swap net with 1500 watts on 75 meters... Neighbor about 1600 yards across a narrow lake participates in the net, no problems. He is usually barefoot, but occasionally under bad band conditions runs a kilowatt, doesn't bother me at all.

    He was 60 dB over S9 today, barefoot. He assured me my signal was pegging his meter hard over, but said my 1500 watts was narrow, clean and tight.

    It won't DAMAGE your receiver, if that's what you are asking . . .

    But whether you are able to hear other stations on the band is another question !

    It depends on how clean his transmission is, but more especially, how your receiver copes with very strong signals.

    If you find you have problems, try switching in the Attenuator (if your rig has one) as this will reduce front-end overload from his transmission.

    Think of it this way. Do you ever listen to the AM or FM broadcast band? Some of those stations run up to 50,000 watts how does something bad happen to the AM/FM receivers in the same town where the broadcast transmitters are located?

    No damage.

    Probably lots of interference!

    I used to work in engineering for a 100 kW ERP FM. Our transmitter was atop Cougar Mountain near Seattle, in a compound w/ LOTS of other transmitters. It was said that that there was a million watts of RF in the air there. Many times, I drove there w/ my 2m FM squawk box radio. While there, I couldn't hear anything but, it returned to normal when I left. :)

    Ever try just holding a 40W fluorescent tube at one end and holding it up in the air, there?

    In that kind of field I've found the tube will illuminate to full brilliance, just holding one end with nothing connected to it.

    "This lights my way at night...":p:)

    Whenever I was at "RF Hill", something was broken, and I was too busy to play with lights. :-/

    There are people living in houses that are only 700 feet away from the WLS 50,ooo Watt Transmitting tower in Chicago. I’m sure their AM radios still work OK. (But it’s probably a lousy place to do broadcast band DXing).
