I believe that for the MS Sinewave inverter/chargers, custom battery 
voltage setpoints will be available for units manufactured within the 
last 6 to 9 months or so withOUT an upgrade to the inverter itself. 
However, you would need a newer remote or a Magnum Hub/Router (sort of a 
super remote) shipping in just a few months.  An MS inverter built 
before that time would need a control board swap-out as well as a remote 
to control those custom setpoints.  Unless Dave Allegre is REALLY fast 
at his new remote control, (Dave did the SW Plus code at Xan-Trace), the 
Magnum 6 port Hub/Router will be first to be able to control these 
parameters.

Sorry... Can't say I know much about the RFI/EMI reduction schedule at 
the moment.

(somebody mentioned the lower RFI on the SW I think)...
 These high frequency inverters like the MS and OB and X-verters tend to 
make more VHF and high shortwave interference, and the lower frequency 
inverters (like mod-square and old SWs) tend to make more AM and lower 
frequency shortwave interference because of the lower switching 
frequencies and BIG sharp edge switching.  Actually, both topologies 
have sharp switching edges but the lower frequency units swing one BIG 
voltage step at a low rate where the high frequency units swing a small 
voltage at a repetition high rate to emulate the sinewave.

The comments regarding this RFI have been forwarded to the others here.  
 Maybe more info for you soon on this... We'll see.  Of course, you can 
be FCC Class B compliant and still make RFI.  Or, you could be FCC 
compliant and not have a sticker.  Being a ham myself, I want the EMI to 
be gone at my operating frequencies.


> And any new info about the "Classic" ?

Well, it looks like that in about a month MidNite will be sending out 
some pre-trial units (an alpha I guess you call it) and hopefully the 
beta should follow a couple months after that. Some of you will be 
working with us on that.  As Robin says "engineers lie" about production 
dates, and I really don't like to do that, so I think I will leave it at 
that other than to say the Classic is looking (and has worked) REALLY 
good and I KNOW you're going to like it.  But that's not what you want 
to hear...  You just want the REAL thing !!    (so do I)
