Mark,
Thanks. I think I read somewhere that DDUtil is required to connect
the Flex for band switching, but I am still looking for confirmation on
that.

There is a bandswitch that might work for the ALS 1300:

on eham say it does work for their rigs:

data from a rig like the TS480.
I don't see how you could do a bandswitch with the ALS-1300 and the Flex
3000. The only thing available on the Flex 3000 is a keying line to
activate the amp T/R switch (which I am using on my THP 1.2KFX and it works
perfectly for my CW QSK needs)
Maybe there is some sort of interface from the computer that ties into the
SDR software, but I am not aware of it.
Also, FYI there are buffers out there from DX Engineering that will do the
trick of isolation.
But I have a few questions first (if I may ask), and perhaps we need to take
these off-board
1. CW or SSB
2. What band?
3. You should not have a problem working cross country, unless it is a
specific instance that goes against the grain of known prop characteristics
of a particular band
Feel free to contact me offboard and I will be happy to help you.

Subject: [Flexradio] Interface between Flex 3000 and an amplifier
I am considering buying an amplifier for my Flex 3000, as it is
difficult to reach from Washington to Florida and Maine with just 100 watts.
Can I have some suggestions for an interface between my Flex 3000 and an
Ameritron ALS 1300?
I am particularly concerned about what is needed to safely key the amp
without damaging the Flex.
I am also interested in knowing if I would find something like the
Ameritron ARI-500 useful for automatic bandswitching of the amplifier.
The Flex is my first radio, so would appreciate some advice.
