Configure the Flex 6700 for MARS Activity

What is needed to configure the Flex 6700 radio for MARS use?

I already know my MARS license must be provided to Flex for a radio-specific firmware unlock key which enables transmit on MARS allocated frequencies.

My question is what software/hardware is needed with the Flex 6700 to produce other MARS-required formats such as ALE and data transfer?

Thanks for any help!

None.... it will work with ALE directly as well as the other software they use.. FYI I am a current MARS operator on a 6500.. simply setting up the proper DAX channels works perfectly.

good source for further information and ask questions:

Greetings David,  Please provide some hints as to how to interface MARS-ALE to the Flex.  I'm at the point where I wish to move from my IC-7600 to my Flex 6700 for MARS-ALE and am just starting to look for the means to do so. 

How do you set it up to scan the proper ALE Group in your QRG?  So far all I have done is create a Global Profile that has all (most?) of the frequencies in the ALE East scan list in individual slices.  Is there a special MMI that I need to have? Thank you in advance!  73, Mark.

There are several others that have setup and are using MARS-ALE with the FLEX radio's that can guide you on setup and configuration.

Flex will send you a program which will unlock the rig. All digital s/w should work fine. Tuner works on MARS freq as well.

I find that I have to cut the TX Audio so low to avoid distortion that the power out of the Flex 6700 is a mere 17 Watts. DAX TX Audio level is at 52. Are others seeing this?? Do I need to adjust something else ? Any help appreciated

I can get full power on SSB. I have not tried digital on MARS frequencies. Did you check your ALC level?

I run my levels right up to the point it will touch the zero mark occasionally.

With M110a that would create distortion. I’m wondering about bandwidth center frequency adjustment??

Len is correct, adjust the transmit stream until the level indicator is just below the zero point while transmitting M110. Make sure you use DIGU as it negates any processing from affecting your signal. If you detect distortion I would investigate other areas of your audio chain. Generally, you will see an output level of approx. 50 watts. Set the high cut value of the TX filter to 3300, at a minimum. Your receive bandwidth should be at least 3k (300-3300). I have used a 6500 and now a 6600 for MARS digital operations since either model has been released. They are great radios for digital traffic.

Maybe by reading SSDR Manual page 73 (you really should read it. Loads of nice to know stuff in that manual ...)

I've read it many times, and your right LOTS of stuff in there, thus you simply can't remember all of it.  Particularly the case for the unique stuff that pops up from time to time
