Thanks. I Was wrong by a factor of a bit less than 3. Only 5dB...186000 is one of those numbers that sticks in my mind, a bit like 3.142, as an approximation (in miles/sec) of the speed of light. Google tells me the number you were looking for is 62,400
Normally, it's not 186 that sticks in my mind, but 168, the number of hours in a week.
but 186xxx sounds like the sail number of a Laser worth about £1200 to me...
I tend to think of the speed of light as about a foot per nanosecond.
But I think some radar people used to define a 'radar foot' as c/1ns?
