Going through my shop tonight I came across my Archer brand (Radio Shack), SWR and Field Strength meter, basically New In Box but 40 years old. It's been about that long since I used it. According to the docs, it's good for both CB and Ham operators. Now I know (or at least assume)
that it's useless as a SWR meter because the AMT-5000 doesn't have the power to drive it, but I'm wondering if the Field Strength meter would still be useful? If you are wondering why I am asking, well yesterday I took my station down I am now in the process of installing the transmitter in a weather-proof cabinet and all that entails..

I use my Workman SWR-3P as a SWR and field strength meter for my FM transmitter. The frequency range of that meter (though marketed for CB Radio) is 1.8 Mhz to 147 Mhz.
So as you can see it would cover 160 meters all the way to 2 meter Ham. FM Radio is 3 meters. So reading the frequency specs often can help you. Radio Shack did have meters at one time that may cover as low as 1 Mhz which certainly would cover the AM band.
Some meters can go as low as 100 mW. I got down to 310 mW and I could clearly use the Watt meter side of the SWR-3P even down on CB. Never assume it won't do it. They even have that same meter modified on Radio Brandy to cover the power levels of part 15 FM.
It pays to do your homework because this $26 meter sure has helped me out.

Legacy, thanks for the response! I will definitely try it out once I have the 5000 back on the air. I use my Workman SWR-3P as a SWR and field strength meter for my FM transmitter.
