[VHFcontesting] TE systems 28 volt amps for roving / portable use

[Mark Spencer]

Hi, I'd be curious in hearing comments about the 28 Volt TE systems amps, especially from any one who has used them in a roving / portable setup and has run them from a battery system vs a 28 volt power supply.

I'm looking at their 28 volt 144 MHz and 50 MHz amps.  They seem like a reasonable way to get 600 watts, if they will work properly at voltages of less than 28 volts (ie. from a typical battery system.) If I need to run them from 28 VDC power supply then they would be much less useful to me.

Thanks in advance for any comments.   

All the best.
