Hello I am Bill, VK2FATE. I am studying to upgrade my licence to be able to use digital modes. In the meantime, I want to connect my Yaesu 450D to my laptop. I would like to be able to experiment with rig control, and learn about receiving digital modes. If it helps to know my laptop, search 'ROG GL552j'. I'm a bit confused with getting the connection right, and would greatly appreciate any help. I believe I need a "9 pin (RS-232?) female to USB. (straight?)" cable for the rig control. As for the data cable, I'm not sure. Is it just a '6 pin data to USB' cable also? What about audio cables, I assume that comes in somewhere also. If you could include a link to purchase the cables (ship to Australia), it would be great to make sure I'm getting the right thing. ( purchased one cheap rs-232 to USB off amazon but it I cant seem to get it to work with PCC-450 or HamRadioDeulux. Assume its not the right type of cable) Would I need something such as signalink in order to do this? If a combination of cables alone works fine, great. If not, I'm happy to purchase an external device to get my connection right. Thank you!
