Today I have finished the small RS232 interface to manage the Motorola GM950 UHF/VHF transceiver. This small interface will cost you about 10 Euro, and will give you much fun ! I had made the PCB layout on the test board, the design is so small that you can easy do this (see picture). The …

In the time we are building on the PCB with the electronics (for PIC controler) I had to bring the old hardware inside a new box. Also the rotation of the Antenna rotor I have to do by hand. But safety first .. the old hardware is build together in a plastic ‘box’ with on …

“Start to build a new management system with PIC-controler for the Antenna-rotor” The next pictures will give the few of the development of the antenna-rotor interface with a PIC 16F84 controler. The development is started on a breadboard to find the correct parts and programming of the PIC controler. I have started with the most easy …

First homemade project ready, Finished the CAT-interface for the FRG 8800 Receiver. This small project is easy to make I used the schema from J.F. Kok with the MAX 232 and his ‘special made’ software to handle the RX. The interface is made in the ‘open space’ of the 144 Mhz transverter who is not in …
