I have a few more questions,
How do you disable the pallet to perform this test?
Where on the pallet do you measure from?
Is it that the positive probe is placed on the +5 and the negative on the ground
Meter in milli amp mode?
Is that correct?

Hi,
Where do you measure the bias voltage or current from ?
Is it the voltage that's important?
Or is it the current?

SWR protection circuit

Hi ,
Are there Any SWR Protection circuits or board available that will kill power or shutdown the transmitter in case of high SWR .

this is very useful in cases where the antenna be comes detuned from excessive sun/rain/ice or coax being tampered with

Re: upgrading my system

I would like to increase the output power of my 25 watt transmitter. In order to increase the internal amplifier wattage wouldn't i just install an attenuator with the bigger amp and keep the RF power below the max range of the attenuator? Although new to radio i can build computers so i am technic...

This is more than enough, the drive power you need typically is just 2-5W, stereo encoder uses practically nothing and fans are also using just a couple watts. You can also connect fans to 24V or 48V directly (these types exist) or even 110-240V. I don't see any need for more, really. M what is the...

pcs wrote:I recommend you use a small attenuator between exciter and pallet. 1-3dB.
I usually use 1-2dB.

It really helps things.

do you make or sell a RF attenuator that will pass 10 to 12 watts on the output, the drive required is 12 watts.
