antenna started flameing and stopped when it stopped transmitting.
75 watts

I carry a fire extinguisher now and am careful. some testing is needed but I may go down to 25 watts.
if it burned more I wonder if it would have damaged the radio.

...and am careful....

Yeah, the radiating antenna looks to be about a foot from your head:ermm:

I don't think the RF power level is the issue, It looks like the coax was rubbed for a while and finally wore down to the braid.

looks like 5 watts would be ok.

actually, at power levels below 50 watts, all 2 meter FM operations are exempt, also, ALL mobile operations on any frequency are also exempted by bulletin 65.

but,..... I still would move or at least raise the antenna above the roofline.
