Partie hardware : la liaison CAT de pilotage de l'émetteur
Your transmitter must have a serial port or USB port for communication with your PC and SDR Console. The modern workstation equipped with USB port, once connected to a PC, must provide a virtual serial link.
For those who use a transmitter that is not “modern”, in other words, that does not have a USB port, you are probably confronted with the absence of a serial port on your PC. I advise you to get one of these small USB/serial and economical adapters, like the ones found here and there:
- Serial port FT232 (Link Aliexpress – Link Ebay)
- Serial port with cover PL2303 (Lin Aliexpress – Lien Ebay)
- Serial port CH340 with choice of signal levels 3.3V/5V (Lien Aliexpress – Lien Ebay)
The connection cable is to be made between the RX / TX and Ground pins of the two sockets. Here is an example of a serial link made for a Yaesu FT-817.
Yaesu FT-817 serial link
You can easily build the serial link cable between your FT817 and your USB adapter or serial connector (DB9 plug).
Connect the substation according to the simple diagram
You can also find USB cables designed with connectors adapted to radio models. This is the one from FT817:
- USB CT-62 CAT Cable for Yaesu FT-100 FT-817 FT-857 (Link Ebay)
- Cable CAT CT-62 forYaesu FT-857 FT-857D FT-897 FT-897D mini DIN male / USB (Link Aliexpress)
The hardware part being realized, let’s proceed to the software part.
