Hello,
I wouldn't touch the radio at all. I'd build an external attenuator on line
with the coax that would be activated by PTT when transmitting. You can use the
linear amplifier control for this. This way it would not attenuate the RX.
Small box with coax connectors, a DPDT relay and a few resistors will do it. No
need for big resistors either if you only want to drop 10W to 1W (or whatever
you want the output to be).

Subject: [Yaesu] qrp mod
good noght to all
is there a member of the groupe wich would have the mod or way of doing to
modify that transceiver for QRP OPERATIOIN
it is a modification wich reduce the bottom part ONLY of the output without
disturbing the high part of the output
as 99.999 % of the transceivers on the market they are sold ( stock ) MINIMUM
OUTPUT ABOUT 10 WATTS wich is too high for QRP operation
wishing to ear soon
