Best money can by for serious VHF operator.  Time owned: 0 to 3 months
I'm running mine for app. 3 months now and this a an amp that gives you a huge amount of headroom for serious DXing on 144 MHz.
The amp consists of 4 times MRFE6VP61K25H, each capable of 1.25 KW. The four devices are operating well below their peak values at 3.8 KW max output running 13.5 watt input! Result: extrem high linearity - very low intermodulation. Silent blowers (fan speed is temperature controlled) are keeping the shack at low temperature and silent.
Built in PS is good for 7.5 KW input at 230V.
Micropocessor controls all the functions in real time:
the protections of the forward and reflected power
outside temperature
the temperature of each MOSFET and much more.
Nice piece of craftmanship from a broadcast pro factory. Happy with it.
