I managed to burn out the input attenuator on my FT1000 by having the RX antenna
connected to a Beverage while transmitting into a loop on 160 meters. The input
attenuator is constructed from chip resistors, but can be rebuilt with 1/8 th
watt standard resistors. Keep the leads as short as possible.
