Re: [Repeater-Builder] power output on 440

I sounds like your amplifier may be spurious.  Your watt meter may be 
reading 15 watts, but not all the power being read is on the output 
frequency.  Watt meters are broad banded, you need to look at the output 
of the amplifier on a spectrum analyzer.

 I inserted a small 20 watt PA after the TX port on our Hamtronics 
 REP-200  UHF machine.

 Repeater puts out 7 watts into my Termaline after all the filtering etc.

I'm going to put it back as stock and see what happens with a fixed 
listening post about 5 miles from me.


Hard to tell in the mobile.

Thank you for all the suggestions.
