Over the last year we, as well as others, did have many issues acquiring components. We are happy to secured all needed components for the next few hundred RF2K-S productions. Plan is to shorten our delivery time to 6 weeks when cached up with the backlog.

All who have received the RF2K+ controller upgrade KIT.
Due to a missing jumper on the new controller your RF2+ will behave as an RF2K-S with fast TX switching.
The fast TX switching will end up in Hot Switching and will destroy you amp !!
Please ensure you’ll perform an online update before you use your upgraded RF2K+
Minimum SW version is G92C110
SW version can be seen on bottom right on the main display
Bottom left on main display you must see “B26 RF2K+ “
CONTROLLER JUMPER !!!
Beside the described Jumper settings in the upgrade procedure you MUST SET JUMPER “C” else you’ll not be on the RF2K+ SW.
Jumper C was not delivered with the already shipped KIT and you can solder the pins together if you don’t have any spare jumper.
Next delivery ( not packet jet delivery ) will have the jumper.
Please apologize for the late change.

We would like to inform you that we needed to release a bug fix SW updae which is mandatory to all RF2K-S and RF2K+ with new controller.
Bug fix for SW identification of RF2K-S and RF2K+
To identify the version of your amp we introduced jumper C on the controller.
During boot up the SW is reading the status of this jumper and behaves like an RF2K-S or RF2K+
Timing issue in the controller could boot your RF2K-S as an RF2K+ which is incorrect.
We fixed the issue and it has been tested by Betta Tester as well.
This update can be installed using the build in update function.
What’s next?

We would like to inform you that we released G91C109 which you can online upgrade starting today July 30.
With this release RF2K-S and RF2K+ with controller upgrade are the first amplifier who supports Expert Electronics SunSDR TCI command structure.
This update can be installed using the build in update function.
Once upgraded you need to install TCI in the Interface / TCI - Menu
At this point I would like to say thank you to the Expert Electronic team for their very professional support to get to this stage.
I also wish all SunSDR users fun with the new feature.

We would like to inform you that we released G82C100 which you can online upgrade starting today.
With this release we completed all promised features and even more.
Some of the already implemented features we’ll be revisited and improved in the future.
We’ll not stop making the RF2K one of the most advanced amplifier.
Due to some changes in the Linux system you need to reboot the RF2K-S twice.
Just follow the instruction on the display.
Have fun

We would like to inform you that we released G73C94 which you can online upgrade starting later today.
Also today we release the updated User Manual in German and English (can befound in Docu aera).
Some of the features out of the last SW release were not described in the user manual, so it was time to do some work on documentation as well.
Joerg DF9LJ did a video about his antenna switching using the external antenna switch feature.
I recommend to watch that video for a better understanding about the new feature.
Upgrade procedure:
This upgrade may be installed using the built in update function.
What’s next?
Have fun
