While building up my remote station, i was looking for a solution to control one or 2 azimuth only rotators via the Internet. There are several solutions and i finally adopted the K3NG rotator project i already used for a rotator controller connected via USB to my computer. |
To be finished...
Some years ago, i developed my own rotator interface with a PIC 18F452. In a need of another interface, i was unable to find my software sources of this project, lost somewhere in the computer Walhalla ! So, i looked for a finished project to build, and found the K3NG Arduino rotator project.
It looked very complete and having some recent experiences with the Arduino, i decided to give it a try.
What i needed :
Years after years, everyone is collecting things that "can be usefull"... But, at a certain time, a housework is necessary !
I have to get rid of a lot of parts and equipments. I have created a small online shop on my Joomla site, using the Virtuemart component.
I didn't setup a online shipping and payment system, so if you need something, please feel free to contact me !
The link to the shop is in the menu under "eShop".
A friend of mine who bought a cheap Kenwood TL922 power amplifier asked me to repair it and to bring some modifications in order to improve the security. This is the fruit of my works...
So, before any tests i have made the following modifications :
- Step-start
- Filament transformer protection
- HV protection agiainst internal valve flash
- Zener diode substitution
- PTT circuit modification ofr low voltage switching
- RF relay substitution
- RF stability improvement
- Symetrical tube feeding
Since the beginning, my brand new TS590s had a intermittent problem. The reception was fading and sometimes disappeared completely. Sometimes, the TX went away and at the same time, the HI/SHIFT setting didn't work above 3000 Hz.
I noticed that a slight shock on the case brought the rig back to live, but not always. Being new and under warranty, i sent the rig back for repair.
