[AMRadio] AM Radio

[Bernie Doran]

same antenna? same modulation level? same time- switching between the two in 
seconds?  same frequency response? same microphone? same compression or 
limiting? everything has to be exactly the same except the power level. does 
it make a difference? of course.  but a big difference?  1 DB is the minimum 
detectable change under the best of test conditions, so this is six steps of 
minimum detection changes.  That is all and certainly not a BIG CHANGE even 
ten DB does not make a big change under most conditions.   certainly can be 
measured with instruments easily, but not by the human ear.     I have in 
the past worked 80Meter AM with a 4 watt carrier, now that does get a little 
tough with splatter around.   I do hear a lot of Rangers and they certainly 
seem to do well with their 50 or so watts.   guess I will get the IC703 out 
again and stirr the pot.
