"However, [PowerSDR] has no knowledge about the outboard amplifier so treats
it just as something coming in to the antenna terminal."
This isn't 100% correct. There is a gain adjustment control on the FLEX-5000
you can adjust when you place a preamp in the RX loop to compensate for the

Actually, that is what I would expect, although 30dB sounds a bit much.
The F3K sees an increase in noise from turning on the pre-amp. Take a

Or use no preamp or the attenuator on the 3K with the ARR. Adding
pre-amplification at the antenna is better than doing it after it traverses the
coax.

Mark,
The 3K is pretty hot out of the box, should not need much if any extra
Pre Amp and you may be at the point of diminishing returns and
amplifying the noise more than the signals you really want. If you can
lower the gain of your outboard mixer to a lower level, maybe lower the

One comment about the Bose speakers - they sound good for SSB, but for

desired as far as CW goes.

I just picked up a pair of Cyber Acoustics CA2992 amplified speakers
at Fry's for $19.95. These are 8W/chan 2-way speakers with two inputs.
They sound great on the F3K and are loud enough to fill the classroom
when I am giving a demonstration and want all the kids to be able to
hear. *MUCH* better
Sheldon,
As Tim mentioned, using a "Y" cable may cause issues. What I do is feed the
PWR SPKR OUT from my FLEX-5000A to the Line In jack on my PC's soundcard.
Then my PC speakers are used for both the radio & the PC audio.

Yeah, but unfortunately you still have the same ground loop dilemma with that
configuration too. It is still best to electrically isolate the second source.
You do not want stray currents flowing through the speakers, especially if
they are high frequency (RF).

I use the powered speaker output on the 5000A to feed the line in on my
audio card.
Requires the computer to listen to the 5000A, but is more flexible.

One nice feature of the Bose Companion II is dual inputs - one set for the PC
and one for the Flex.

One word of caution. Putting a "Y" audio cable between the PC and the
FLEX-x000 powered speaker output will cause a ground loop between those two
devices. It is best to electrically isolate the two sources or use an audio
switcher.

Hi Joe
I use Bose Companion 3 Series-II speakers with my Flex-5000A and really like
them!
One thing to keep in mind is that you will probably want to feed both the

What can be recommended as a quality, RF immune 2.1 speaker set?

I understand Bose speakers have a stereo simulator that Bose does not
