I would like to trade my AM-7148/GRC-206 150W amplifier for the coupler/amplifier that attaches to the side of the PRC-104 R/T.  This is for the amplifier and shock mount only, not the R/T, also the power cable and interconnect cables are included.  The amplifier will work with the standard r/t or the longer version with the security module installed.  Amp is in good working condition with auto tune function.
