I bought a transverters store 146 to 10m transverter with attenuator board for Christmas. After moving the shack around, I forgot to swap the antenna output on the rig. Which means I accidentally ran 60w into it while it was powered off. The max is supposed to be 5w. It still receives fine, bit doesn't transmit. The transmit light comes on, it sounds like a relay comes on, but no output. I pulled it apart, but there is no visible damage. I pulled the mosfet and that tests out ok. Any idea where I should start looking? Tldr: ran too much power to transverter, what is broken?
