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).

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
