Can I use the ATU from the 6300 in the 6400?

I have a Flex 6300 with ATU. Does the new 6400 use the same ATU, or must I buy a new one?

I asked Matt that same question the other day. Unfortunately the answer was no.

That's incredibly short sighted. One would have hoped for an evolutionary design from the original Signature series. I bought this radio only 3 years ago when it was introduced at Dayton! Last one that they had at the show. This sets a new low for product obsolescence. I love my 6300 but am really pissed at Flex for the short product life.

Hi Paul,

thanks for the feedback, much appreciated. Whats your thoughts on the Anan 8000?

Best regards,

Richard.

Hi Richard.  Sorry but I have no experience of owning or using any of the Anan's.  At the time that I was looking (2 years ago) I was put off by the comments that likened the ownership experience as being 'like a science project'.  I notice on one of the other threads on this forum, a UK amateur (Peter Bentley G4BIM) has done a comparision...give him a shout..  Cheers  Paul

Thanks, I have seen the science lab comments, a lot of money for a school project in my opinion, that would worry me.

Cheers.

Do some research on the Anan vs Flex. Pick the one that is right for your operating preference.

The Anan with the open source software gives you a LOT of parameters to tweak, if you like doing that. The radio requires the user to perform some calibration. For example the Anan uses one calibration point per band for RF out (usually at 100 watts). The problem is the power slider is not linear and varies band by band. A setting of 20 on the slider may be 22 watts on ine band but 45 watts on another (my 200D was even worse on 12 meters.)

The Flex comes calibrated from the factory. The only calibration you need to do is the reference oscillator which is accomplished by clicking a button in the radio setup. It will switch to WWV (or you can enter another frequency) and it will auto calibrate.

The other big thing for me is the Anan hardware is still "fat client" vs Flex "this client". This means the Anan will always need a PC on locally to run the radio. The Flex can be located remote and plugged into a network connection with Internet access. Mnay people here are using VPN solutions to access the radio remotely and with 2.0 software due out soon the meed for VPN is gone.

The Flex also supports different USB cables plugged directly into the radio to interface to various hardware such as amplifiers, auto tuners, antenna switches, etc. so if you are considering remote operation keep that in mind.

Obviously people here are biased towards Flex radios and most answers will skew you towards a Flex. I owned an Anan 200d and sold it. I currently own a 6500 which is at a remote location 1100feet above sea level and a 6700 at the home station.

Do your research and make an informed choice, but I would not go Elecraft if you want to be able to tap into the potential of true SDR radios.

It is electrically and mechanically different than the 6300 ATU.  it has the same matching characteristics as the 6300 ATU.
