FT 450 How to Power Adjust to 1 watt?

HI Fellow Ham Operators

I have the FT 450 Yaesu

I can adjust the RF output down to 5 watts, does anyone know how to bring down to 1 watt..(I have a solid state Amplifier)

Don't use the amplifier and use some form of attenuation.

 

I don't have the attenuator! I had all that before, sold everything, just getting back into Ham radio

I am borrowing the FT 450, and using low power is what I wanted to do, the AMP is mine, so I can work this...So 5 Watts, get 350 Watts out, and that is not what I want, I would like to use about 50 Watts, or 100W,,,

No worries I did find a solve...Although very touchy, I use the signal link, TX Gain knob, and work it down to the 100 Watts...

Thank you all for helping

A 50 ohm resistor will work wonders.

 

I sure does! 50 Ohms

But the TX Knob on Signaling, is more granular, (Although touchy), So all good

Attenuators are super easy to build - use this calculator if needed.

Good luck !

I found the solution, Before I give the answer, I have been away from the digital modes for a few years, and there is a really simple solution!

The WSJT-X has a power adjustment on the right hand side, this perfect, as it has the granularity I need..'

Thanks all for your input

If you want to run 50 or 100 watts, forget the amp and just set the 450's power level accordingly.

 

Of course I would...But this is not my HF Radio, (I borrowed it), I am using lower power, 5 watts in this case...Nothing worse than borrowing something and returning in broke! So using on 5 WATTs for digital is safe, and the AMP, is mine...So I can use as I please..

Hi,

The needed resistors for a homebrew attenuator would probably be about $10 including shipping from Digikey or Mouser.
