>> 
>> The second question is what is the "best" meter in the portable class
>> that does not cost as much as a piece of laboratory test equipment.
>> I'm currently using a Daiwa CN-801 between the amp and the Palstar AT5K
>> tuner. The 801 which is 2KW full scale goes right up against the pin
>> at
>> full carrier into a Palstar DL5K dummy load. The AT5K internal watt

>> either of the two against the Bird 43. I'm well aware of many of the
>> problems getting an accurate reading which is why I'm working into a
>> "dry" dummy load with two honkin big resistors and TWO fans that sound
>> like I need to tie the desk down when they kick into high.
>> 
>> This leaves me with two problems. One is the requirment for a meter

>> much full scale means that when running the legal limit which I desire

>> that adds in. I would *like* to come up with something that will be
>> good
>> enough to use as a reference for the meters in current use at least
>> into
>> the dummy load. The CN-801 is generous enough that when it shows 1500
>> PEP I'm likely to be some where around 1 KW PEP. Yes, I realize the
>> difference between 1 and 1.5KW is not very large db wise.

>> Any suggestions?
