Hi Group,

I have a FCV-261 1K Watt sounder I want to use with a 150 watt transducer.
The FCV-261 has a four position power attenuator switch on the output going
to the transducers.
I can't find any info in the manual as to the power output for the four
positions.

I can measure the output of the amplifier, but a quick answer would save me
the time to lug all my test equipment on board. :-)

Can anyone shed any light on this?

Thanks in advance,

Really depends on if the FCV-261 is Multi Freq or a Single Freq
machine. I can't remeber for sure, but if it is a 50/200 then
you will want a MultiFreq Transducer, similar to the OEM
one that came with the Unit. If it is truely a Single Freq
Unit, then I would only worry about the Power Switch position
and that can be determined by going out to Deep Water (100 Fathoms)
and lower the Receive gain to a just barely detectable bottom,
then switch the power Switch back and forth while watching if
the bottom disappears on each position. This will tell High
from Low very easily......
