HNY all:
Apropo of the recent discussions on "dirty" RF I have been considering  
putting together a "station monitor" to monitor my RF output.  I have a K3  
(7588) but also an ICOM 7200, Drake TR7A, Drake C-line & a couple of  amps.  I 
have a 70MHz occilliscope that I would like to place between amp  & feed 
line to various antennas.  I want to make sure my CW & SSB  output is clean 
without clicks or splatter, especially at higher output.   This would allow me 
to see if there is any effect on waveform from the amp  compared to the 
transmitter output as well.  Some sort of attenuator is  needed to protect the 
'scope but also to make sure it doesn't change  the impedance the amp or 
tuner sees.  I understand the Bird wattmeters  have such a "sniffer" circuit.  I 
also understand the 'scope alone may not  be sufficient for such a "station 
monitor". Any suggestions would be greatly  appreciated.  If this is not 
appropiate for this reflector, I apologize,  and would be happy to take 
replies off list.  Tnx & hny to all.
