Power out

Paul F6EXV

Hi all

I have a x 6500, running on SmartSDR 4.1.5 Win 10 machine.

Yesterday, when switching the rig on, I noticed the power out was not what it should be… It is set to 100W, and the display shows just about 55W out.

When trying the tuine button, set to 100W, it shows the same. The strange thing is, when I stop the tune, the SWR will go all the way up to infinite and slow drop to zero and a half seconds.

Reeception also seams to be affected (or is it propagation ?).

What would you recommend me to do, to check what went wrong ?

Often, when this happens, the DC power on the back of the radio is low.

If you use FRStack to measure the internal DC power while in TX with TUNE set to 100%, what do you get for a voltage reading?

Hi Paul… first, let's check that the rig itself is OK. If you have a dummy load available, attach that to the Flex and try again. If you're still not getting a full 100W output (or close to it), then I would open up a Help Desk Ticket.

If everything is OK with the dummy load, then it's likely something in your antenna system after the rig. The Flex will 'fold back' power to protect the finals if the SWR is too high. You may be seeing something like this.
