Checking Transmitter Signal Power Without Powering Up

AI Thread Summary
To check the transmitter signal power without powering it up, users suggest researching the make and model if it's a commercial unit, but since this is a DIY unit, that may not be possible. The discussion highlights the need for new output transistors and the importance of not powering the transmitter without an antenna to avoid damage. Participants also question the safety of transmitting while attempting to measure power levels. There are no specific methods provided for measuring the power of a DIY transmitter without powering it on. Ultimately, the feasibility of repairing the unit depends on determining its power output and condition.

Hi,
How to check my transmitter signal power? I have found my transmitter in my friend shed and needs some new output transistors. But i don't know what is the power of my transmitter and if it worth to repair it. There is the RF board and also a encoder. There is also an amp so i don't know how to check its power. At the moment i can't power it up as i am building the antenna (harmful to switched it on without antenna). Is there any other way to check its power?
Thank you

I assume this is some kind of home brew/DIY unit? Because if it's a commercial unit, just google the make/model of the unit...
 
yes it is a diy home made unit.
 
I am sorry but if its a DIY unit what is wrong with transmitting and simultaneously trying to go out of range with a hand radio.

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
