Mar 27 We are working with SM2O Mikael on a project to remote control rigs over Internet, not just the QROlle. For that we have a developed the "Remote Rig Controll". It is basically a CPU-board and display that handles CAT-commands over a serial interface. More information on that shortly.
Mar 21 Nils SM5DEH and Tilman SM0JZT exibited the QROlle line of radio-kits on the yearly Ham Radio Fair in Eskilstuna/Sweden. Many OM:s came along and had a peek at our kits. Unfortunately we are not yet ready to ship kits. But all components are bought so we are very close.
Mar 11 Here is a downloadable PDF-document of the block diagram of the QROlle II Analgue parts.
A number of teleconferences have been done over the last couple of weeks with the QROlle team. We are working out component supply and design and shipment details with the case and kit delivery project.
Feb 6 Time to order components and set up the QROlle shop! We are now working hard with gathering components and start working on the order process for the KIT-ordering. Shurely we are getting there with things.
Jan 18
The kit building documentation is worked on at this moment. The Final Boards A and B ar documented. The "Digital" boards C and D will be shipped mainly prebuilt.
Jan 11, 2009 A lot of time is spent doing the kit-building documentation. Today all up to the building of the reciever has been completed. Now the DSB(SSB)/CW-generator and PA is in turn before the meachanics is to be documented. So we are getting closer now.
Dec 29 We are now starting to build the second run of prototype boards before going live with the kit-production. Look out fot a new Video to the project below.
Dec 5
We finally have the layout of all the boards (A to D) so we can start ordering them for the upcoming kits. Next part of the project is sourcing components and doing all the extensive documentation needed. Watch THIS space.
Oct 31-Nov2 QROlle will be shown at the "hobbyfair" in Stockholm. Visit us at the SSA-boot. Look in the homepage of the hobbyfair for opening hours.
Oct 4.
Looks like we can surely say that the QROlle is a proper CW-rig now. SM5DEH and SM0JZT had a demo-session at the Haninge fleamarket today. All CW-operators where very pleased with the CW-functionality. SM0BYD Hans really did fall in love with the possibilities.
Sept 20.
It has been a lot of hard work with the software. We have had quite a bit of help with the design of the bug-software by SM5COP and SM7CBS.
Sept 8.
We are starting to upload software to the homepage. These are to be used for programming the QROlle.
Aug 22. It is now possible to load software into the CPU via the USB-interface. Nils has been working hard with this for a long time. Tilman is doing documentation to describe the upload process in text and graphics.
July 20. It looked like the AD9834 CRUZ did not accept a 100MHz reference signal. Some chips do, but not all. We tried a 75MHz reference. But with some tweaking of the oscillator driving the DDS chip fixed the problem and we can now use 100MHz for a clean DDS output.
July 17. First Video on YouTube related to the QROlle-project.
June27: SM5DEH Nils has finished assembling the A and B board today! Looks nice doesn't it! Lets see who is ready next. After that a lot of testing is needed.
June 14: Round of Beta test units are now being built by the QROlle-team. The reason for this is to find the eventual mechanical and electrical problems before we start the production of kits.
June 12: The QROlle-prototype has been sent to SM4DHN Lars-Bertil for evaluation. Lars-Bertil is going to work hard on the details with components.
June 6-7: The QROlle-prototype was on test and display during the Uppsala Radioamatörer fieldday in Uppsala. The prototype was also discussed and demonstrated at the SK0TM operator assembly meeting

une: We now have a official e-mail-address for all QROlle-queries. Direct them to: 

May: SM5DEH Nils with support from Tilman has been working hard with the software details. The user interface is now very intuitive.
April 26, 2008: QROlle presentation at the SSA yearly assembly. Here are the slides (3meg pdf)

Presentation at the yearly assembly for SSA in Sweden. April 18 2009. QROlle was there! 

In the picture you see SM6DJH Olle and SM5DEH Nils in a rare quiet moment during the exebition April 18 2009. The QROlle is on stand and a lot of interested OM:s stopped by asking questions and signing up for the upcoming kit.

QROlle was there !

On the desk you see the QROlle rigs on display. Far down in the middle you can see the brand new Remote Rig Controller by SM5DEH. With that you can remote control a QROlle or other rig via CAT commands. In white shirt SM0JZT Tilman. SM5DEH Nils peeks out behind the guy in brown jacket. On the desk next to ours SM2O Mikael displayed the very interesting remoterig devices. With that you can run your station remote over Internet. Not just the QROlle....

Pictures from project

In this picture you can see SM6DJH Olle and SM5DEH Nils in the lab of Nils. They have been discussing different components to use.

The team had a very interesting and usefull meeting June 2 2007. We met at teammember Lars-Bertil SM4DHN:s place, Just outside of Hagfors.

The guys are from right to left. SM6DJH Olle, SM4DHN Lars-Bertil, SM5DEH Nils and SM0JZT Tilman

In this picture you can see Olle SM6DJH and Nils SM5DEH sitting and discussing the next generation QROlle. The box in the middle is a prototype of the rig. You can see the size of the rig to come.

A stack of QRP-rigs meeting May 1, 2008. From bottom, the Elecraft K2 is a proven design and a very good performer. In the middle you see the QROlle Classic. On top you see the QROlle-II. It says 5 Bands, but there are actually 6 bands in this prototype.
