Hi to all, i bought the Kl-60 from RM italy, when i connect to the radio the RX signals decrement about 2-3S, could be an attenuation from the AMP? or could be the coaxial?

This AMP hasnt PreAMP.


Can i use the IRF520 or ERF2030 for remplacement for the RM3 Mosfet?

hi Rick , the mods was made and works fine.

thanks for the info and 73's
