I setup my 6500 and SPE 1K-FA this afternoon via USB using the same cable I made to use with DDUTIL and it works awesome. I set the SPE drive levels and am quite pleased with how it operates.

Larry, are you saying we can plug both USB cables from the 1.3k-FA into the Flex USB port with v1.10.8?

Yes. That's how I have mine setup. I have one serial adapter associated with each antenna so when that slice gets TX enabled it sends CAT data.

The rest of the story:  I connected and brought-up my 1.3k-FA as described by DDUtil and all worked as advertised, first time...

The only cable I use is the rca to key the amp. I set the Flex fo 9 watts max output and set the tune power to 1 watt.  9 watts gives me 1200 out of the spe 1.3.  I cant really see the advantage of having a lot a cables.

The USB on the SPE expert amps does not carry CAT data. Only the 15 pin Dsub connectors do. The USB is just for the control software.

The drive power lowers to 20 watts when amp is switched to operate, i need to drop to 5 watts, where is this power level set, i can't adjust it manually with the mouse when amp is in operate mode.

Press the arrow buttons (right side, NOT the L and C buttons) on the amp and it will raise/lower drive power. You need to do this for each band as well as for Low/Mid/Max, and yes, drive power on each band for max power is different. Do this once and the amp will retain these settings and automatically set your drive power whenever you switch bands. I also set 30m to 1w drive on all 3 power levels. This way I only get 200w out.

Thanks Ria, Is there a way to control the operate button on the Amp from the radio rather than from the Term 1.3KA usb  program.
Cheers

currently not possible. However, you can do it in DDUtil.
