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.

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

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...
