I bought a power mosfet amplifier by a surplus dealer here in Sicily.
It is the Motorola MICOM 1000 (a chassis with two power supplys and a
very nice amplifier with four amplifier modules - each one with four
MRF150).
The amplifier is designed with a frequency detector....it senses the
excitier
frequency and switches the output filter, and many features as temperature
control, SWR, etc.
My first question is: if someone of you, dear friends, knows this
amplifier....how
to feed it with an ICOM radio (IC-765) ? The Motorola amplifier needs a
"channel change" 25ms pulse, it replies a "Tune" command to the radio and
detects the frequency in one second after it receives RF....
My second question: the manual says the amplifier gives about 1000 W PEP...
but I believe that if a single MRF150 can give 150 W of RF, 16 of them
should
give much more of that specified 1KW power... isn't correct ?
Last question: what should be the value of this amplifier in the market ? I
bought it
for one million lire....was it a good business ?
Thanks for reading,
