Hi all finally got my Flex-3000 up and running on DM-780, I only intend to use my radio for digital modes RTTY, PSK-31 and the likes.

Just wondering if the PA in these radio's are good enough to transmit full duty cycles for long periods, not constant but you know what I mean send a macro and then wait for a reply and so on.

I run a max of 30-40 watts in the digital modes.

any info would be good thanks

It is fine to run full duty at a 100W, The fan will speed up as it needs to. The amp is protected from over temp anyway. Have fun, that's a great radio.

As per the FLEX-3000 specifications, the PA in the FLEX-3000 is a 100w nominal class AB full duty cycle RF power amp operating on the 160-6m ham bands. Operating full duty cycle high power digital modes, like RTTY should present no problem with the FLEX-3000. ┬áThe fans will ramp up to cool the PA heat sink as necessary.´╗┐
