Hello All,

A general aviation pilot friend of mine brought me a wattmeter with an
adjustment between the wattmeter and the swr meter. It ranges between
0 and 10. The only marks of identification are Mura CBM-30. So my
questions are..

1. What is the darn adjustment for?

2. What frequency range is for? VHF would be ideal...

Thanks in advance for any information,
Chris
