When an emergency occurs, the first rule is to be as self-sufficient as possible. As you know, I'm a firm believer in...
Microwave Operation Tricks of the Trade

Relative RF Power Meter
Add this handy device to your shack's arsenal. The Relative RF Power Meter shown in Photo A is a. piece of test equipment useful for tuning RF circuits to maximum output power. The circuit does not measure absolute power, however it instead measures the relative output power as the RF circuit is tuned. When the meter shows maximum deflection, the output power is peaked. The meter has been tested from 2 MHz to I GHz over an input power range of approximately -10 dBm (0.1 mW) to 20 dBm (100 mW)....

Info
Together the test setup shown in Photo B. Set a signal generator to any frequency in the 30-50 MHz range. I used an MFJ 249B SWR Analyzer as a signal generator. A step attenuator, such as the one described in the April 1999 issue of Electronics Now, can he used to reduce the generator output to the weak levels covcrcd by the dBm meter. Set the step attenuator for 33 dB of attenuation to reduce the MFJ's normal level of +3 dBm to a -30 dBm level. Feed the weak signal to the range extender input...
