Hello all, I just purchased my first amplifier (Palstar LA-1K) and high power auto tuner (Palstar HF-AUTO). Anyhow, the amp arrived today and it says I need to connect a PTT cable (customer provided) from the radio to the amp. Okay, I'm guessing it needs to be customer provided due to the different possible radios you may connect to it. (I currently have three, FT-450D, KX3, (not sure 15w can drive it at all though) and a Flex 6400) Well, I searched and do not see any documentation about how to create one of these nor can I find a purchasable pre-made cable. I would like the ability to attach any and all of them to the amp. Anyhow. Any guidance on making one or where to buy them for the listed radios would be great.
