SWR meter

Is there a simple way to convert a Radio Shack SWR meter (27MHZ) to
aircraft radio range (120MHZ)? Anybody done that?

This question comes up about every 6 months.

The swr may or may not be reasonably accurate in the vhf frequency range,
the way to tell is to compare it against a known good meter with a transmitter
and a good dummy load and also with a typical antenna. If that CB meter has a
power range, ignore it; it will read high.

The best solution is to watch eBay and buy yourself an old Bird model 43
Wattmeter. You will also need to find a 25C slug which will do you for up to 25
Watt transmitters in that frequency range. You will have a fine piece of
equipment that will last you the rest of your life.

And possibly an even better deal than a Bird model 43 is a Telewave
Wattmeter. Telewaves do not have frequency selective slugs. They work
from 2 MHz up to 500 MHz or more. All you need to do it hook it up
inline, turn a switch to read forward and reflected power and select the
power range. The nice thing with the telewave is they have a 5 Watt
range which is great for reading power from a handheld radio.

In a Ham Radio shop , possibly Radio Shack, you can get a swr meter for the
144meg vhf band which is quite useable on the aircraft band.
