Hi, I'd like to know how to use a Volt meter to measure the output power in the MAXPRO 1, since I don't have a SWR meter for adjusting the transmitter, or another suggestion.
Thanks.

ok
You need a SWR meter to align your antena.
MAX PRO I does have a crude "power meter",
but this is merely for tuning the output stage
and is not suitable for tuning your antena.
You need a true SWR meter.
The 5W booster does, however, have a SWR bridge onboard
and you can use this to measure SWR and power.

SWR metering
See if you can locate an average CB SWR meter and a 50 ohm dummy load. Test the meter on the dummy load. If you get a reflected reading of 1:1 or close to it, the meter is probably reliable enough for FM work. Most of the meters I have work up to at least 150 MHz (2m ham band), even one real cheap one. Used CB equipment is pretty easy to come by.
To use a voltmeter to measure output power, you need to make a simple RF probe (a diode and capacitor)and use a high-impedance voltmeter (not the $10 little black box type). Once you know the voltage, some simple algebra (Ohm's law) will calculate the wattage. If you need more details, let me know.
