    Does anyone know if a variable power mod exists for the 980 SSB?

    It's already a low powered radio, what are you trying to do? Like 711 stated, there should be an AM carrier VR pot as well as a SSB power VR pot. You should be able to set it up to match a small amplifier the way it is.

    here is the locations for the VR's to adjust dead key and mod
    RT203 SSB ALC
    RT205 AM AMC
    RT206 AM POWER.

    be very careful turning these little VR's. they break very easy. you break one and trying to find one and solder it back in place is very hard to do.

    Thanks for the replies, much appreciated. I should have been more clear, the radio I have has been equipped with a “stinger” mod which yields around 120W PEP so I’m trying to find a way to turn the power down, there is no button to turn the stinger off. Thanks!

    Lowering the AM pot effectively lowers over all power unless you NPC mod it.

    Maybe look up the wiring and see which one is power wire and install a switch on the back or side..

    what stinger board is in it. most have 2 wires to turn it off. as mentioned you can lower the radios dead key to turn it down also.if it is the ad-203 from RM it has 2 wires to turn it off.

    Thanks for the replies! I believe it's RM Italy AD-203 stinger board so it should be fairly easy to just add a switch and call it a day I suppose instead of messing with variable power.
