TK-790H Power Question

[Seven-Delta-FortyOne]

Can you set some channels for high power and some for low power, like you can on the TK-x80 series?

And if so, what can you set the low power to?

Could you do say 80 or 90 watts on high, and 35-45 on low?

Thanks for the help.

You can set individual channels to high, medium or low power.

However, what high, medium and lo is set to is done via the service software. There are limits on what you can set them to.

Specs call for:
high = 110 watts ± 5 watts.
medium = 45 watts ± 1 watt.
low = 5 watts ± 1 watt.

It's not as easy as just setting those alignment values to what you want, there's an alignment procedure involved.

Thanks for the quick answer, Mckenna.

Appreciate it.

Is there not an issue with trying to drop the high-powered 90 Series to 5 watts, i.e. that the PA was not designed for it?

I have a TK790 and TK890 in dual-band single-head configuration and can drop the 40-45 watt high to 5 watts within the programming software.

The actual specifications from the service manual (especially since the 90 series doesn't have a medium power option).

TK-790H: High Power: 110W+-5W Low Power 45W +- 1W
TK-790: High Power: 45W+- 1W Low Power 5W +- 1W

I wouldn't take the 790H much lower than 40W. Get a low power model for that.
