Can anyone shed any light on this?

My TS570 transmit power seems to be limited to minimum whatever level I
choose through the menu. I don't have a power meter, but with a dummy
load,it will only draw a maximum of just under 3 watts on any band. (cw).
The AT doesn't work either. When I invoke it, the meter shows max. ref.
power and a relay chatters until turn off the AT.
I'm suspisious that one or more relays in the bandswitching circuits have
failed.
Otherwise it works fine as a QRP rig.
Thanks and 73 for 2004,

It sounds like the SWR protection is keeping it shut down. If your jumper cable
and dummy load are all right then the problem must be between the final amp and
the RF connector. I have seen this problem on the rigs with the connector on
short pig tail from rig to save space. The center conductor breaks from the
flexing. if the connector is on the rig then check the wire from the circuit
board to plug. Last thought is a shorted Cap in the final matching section. Or
as you mentioned a faulty relay.

73 and good luck.
