I'm interested in hearing from FLEX3000 owners who use their rigs mobile. I
use mine with a desktop and love it, but am travelling south now for the
winters. I'm considering using either the FLEX 3000 mobile with a Lenovo
ThinkPad T520 423946U or buying a used Icom I706MKIIG and a LDG

I would forgo the tuner and make sure you have a mobile antenna that tunes.
You'll find that the antenna like a screwdriver design is much more
efficient and radiates significantly better. If you use something like a
tuned whip, it is most efficient when tuned to its operating frequency.
Regardless of legal concerns, the laws exist for a reason, attempting to
operate a laptop while driving is extremely dangerous to yourself and
everyone around you. I wouldn't want to be anywhere near you or
approaching you from the opposite direction. Don't do it! I had a very
close call a
Have a small amp that I want to use on the 1500 but do not see any ALC output
to connect to the Amp, however since the oiutput is only 5 watts, is this a
problem? I intend to connect the PTT circuit to the amp for on/off control.
Thanks for your help.

Many amps rely on that ALC connection to allow them to cut back on
drive in the event of a malfunction such as an intermittent flaky
antenna feedline. A momentarily open/shorted antenna could be very
bad news for some amps under normal drive.
Some argue that you don't really need ALC. I
I don't know of any amplifier that relies on an external ALC connection
as part of the fault
detection. How could it? The exciter transmitter drives the ALC and that
radio has no connection to the
antenna on transmit, so can't see the bad load.
Depending on the design, commercial amplifiers
Hi Roger,
I've been planning on getting a small amp for my 1500 and have been wondering
the same thing. The article referenced below may help a bit, although it
doesn't appear to offer any solutions on what to do when the transceiver isn't
equipped with an ALC jack.
Bad wording on my part, the exciter doesn't drive the ALC.
The rest still applies, though.

Ok, having completely messed up that last one, I once again note
that multitasking has its limits.
IF amplifiers fed back some kind of ALC ramp to the exciter on
VSWR fault, then that would indeed be a valid use of ALC for those
purposes, assuming it was set up correctly. What commercially
KY4RS,
I use my 1500 with an amp with only the PTT for switching with no problems.
As you said, since the 1500 is only 5 watts, it should work fine, especially
if your amp max power input is more than 5 watts. 73

I have mixed reviews. My 3000 worked well at home... but after two
dxpeditions with it in the field over the past 3 months... It's very
sensitive to obtaining a good RF ground, which I never could achieve (or at
least didn't care to haul all the necessary stuff to do it along on the
trip).

I understand that the Flex 3000, and 5000 are rated for 100% duty
cycle. Ok to run SSTV and long winded RTTY at full output? Any cautions??

Then I stand corrected. Some of the newer solid-state amplifiers will
indeed work in
the manner you describe.
If there's a choice, I still believe ALC is a bad means by which to
achieve a good thing.
If you happen to have their wattmeter, then this might work without the
radio connection:

Yes. Whatever you do, be absolutely sure to NEVER stay key-down for more
FYI, the new Flex 6000 series radios have standard hardware ALC. I
don't know for sure, but I THINK Flex was the only major manufacturer
not providing it in their radios until now.

Hi,
The Flex-5000A and companion Desktop PC that I posted for sale on August
21, 2012, at 13:24 EDT, have SOLD.
Thank you for your expressions of interest in this equipment.
