Re: Tuning a pi-Network Output


 

Yep. That¡¯s what I was trying to say.?

The reason it¡¯s done on 10 is because that¡¯s the most likely band that would give you trouble.?

Barry and Steve,

Neutralizing an RF amplifier is occurs ONLY on the frequency
it is performed on. This typically is done on 10 meters on an amateur
radio transmitter/transceiver final amplifier.
?
Once the neutralizing adjustment is performed on 10 meters, do NOT
make any changes to the neutralizing circuit on any lower band. You
will not see the same maximum RF output at maximum PLATE current
dip on any lower band. This is NORMAL and should NOT mean you have
to make changes to the neutralizing circuit on the lower bands.

Follow the manufacturer's transmitter loading/tuning instructions
in the operator's manual.

The Drake MN-2000 watt meter is an "average watt meter". Do not
expect to see "SSB PEP" RF levels on the MN-2000 watt meter.
