RF2K-S is again on the biggest Cruise Ship in the world.
Jean-Paul XE1C who was using his RF2K-S on “Harmony of the Seas” last year cruising in the Mediterranean Sea took his RF2K-S back home to Mexico after his assignment.
On his new assignment he bought a second RF2K-S and the RF2K-S is again on the biggest Cruise Ship.
We do see more contest station who move towards the RF2K-S
Product stability and features is what contesters like about the RF2K-S
VY1AAA/ VY1AA Jay is also happy with the RF2K-S at his remote station for the NW territory section NT
D4C Monteverde Contest Team Club also moved to the RF2K-S

We do appreciate that the RF-KIT Groups.io has such high attention.

Emergency update RF2K+ new controller

2021-08-10T18:45:39+00:00

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.

2021-08-10T18:40:19+00:00

RF2K-S SW G92C112 Release information and upgrade procedure

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.

Release features:

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.

Upgrade procedure:

This update can be installed using the build in update function.

What’s next?

Amplifier TCI command structure extension as there are no TCI or CAT commands defined for amplifier.

On QSY Tuner will go automatically in AUTO if in MAN.

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.
