als 600s amplfier connection to the 6400M

KB4OIF

With the 6400M Flex, is it compatible with the ALS 600 Amplifier.  

Tim - W4TME

Yes. Just like all the other FLEX-6000s.

Thanks  Tim.  I am just getting started with flex radio's. My Buddy W9NWR up in Wis. runs a 6500.

Connecting the ALS-600 is not as straightforward as with other amps.  When you get ready to do it, I recommend sending a post to the Community to get information on the "best" way to do it (there are several ways to skin the ALS-600 "cat" (there is a pun in there)

KB4OIF

Thanks.  My ALS 600 does not like SWR above 1.7.    What is the ratio on the flex tuners  Is it 10 to 1 or something else.  3 to 1.

With the ALS-600 to control the Band to follow the radio you will need the MFJ ARB-704 interface and a FTDI cable ACC-USBPARALLEL  that FLEX offers with flying leads, wired as BCD into the ARB-704.

I think the FTDI serial port cable will also work but been to many years for me to remember since I used the ARB-704 and it MAY need a Null Modem adapter, run it in Kenwood Mode.

Look also for wiring up a ALS-1300 which uses the exact same wiring as the ALS-600, the ALS-606 and ALS1306 have the ARB-704 built in so may be of some help, Just no plug and Play solution you have to do a little wiring. 

The Above cables can be connected right to the back of the FLEX Radio's BUT I would recommend using a Powered USB Hub that is powered by 12V and using the Stations Power supply to take any load off of the Radio's USB ports.

Just my 2 cents

Hi Bret.  i have an ARI-500 interface that I use with my 7300 Icom.  It may work with the flex.

Hi John.  By piggy-backing on others' guidance, I successfully configured an automatic band-switching cable to connect my 6400M to the ALS-600's ARI-500 interface.  I just finished uploading the results: full particulars appear at bottom of this page...

Thanks everyone.  I can not build stuff like most of you can.  My hands do not work very well at times and they shake a bit.  what I am looking for is the correct commercial cable/cables that will hook to the ALS 600S and a diagram as to what cable goes where.  Some folks are saying it's just one cable, some are saying 3 cables.  does the manual have anything that shows this.  I am not going to hook the amp to the flex until I am comfortable with using the flex.  i.e. have a better understanding of what does what.

Are you referring to the internal radio Tuner?  

KB4OIF

Yes Jim.  I know it's 3 to1.  At times it does a little higher.  the 1.7 is a little low.  I did that when I first got my amp back a ways.

I have contacted ameritron and they said that this cable, RJ-8MY2CABLE, ARI-RIG, RJ45-8 MD, YAE, along with the 8 pin mini din plug that flex sells will work.  any one know which cable this is.

Message:

If you want to use the ARI-500 with your FLEX radio, you will need to contact FLEX. The sell a cable that will plug into the USB port on the back of the FLEX radio and has an 8 pin mini DIN plug on the other end that emulates a Yeasu radio. You can then get our RJ-8MY2 cable. The RJ-8MY2 cable has an 8 pin mini DIN plug that will plug into the end of the FLEX radio cable and the other end will plug into the ARI-500.

The USB to 8 pin mini DIN Yeasu cable is available from FLEX. The RJ-8MY2 cable is available from your favorite dealer or for online order off of our website.

Best regards,

Got the cable ordered from flex.  Thanks Mike W.

Good Afternoon everyone.  You can mark this one as solved Tim.  I worked with John at ameritron this morning and we have it working like it is supposed to.  Might have been a little pilot error or and bad RCA cable.
