![]() ![]() Unplug the radio DC lead and all other leads incl.There is no need to have PEP output of more than 100-110W PEP by the way. On a sidenote the peak to average ratio also improved. The PEP output power increased from 75-80W PEP to approx 140-145W PEP (14,5V DC input). I did only one of the mods that involves a jumper from C1509 to ground, because the other mod that involves a 10uF capacitor is reported to cause modulation issues on FM and AM. Icom IC-9700 Users Ive been asked by several people for the CAP/MARS mod Facebook. There are two published mods that are possible on this radio. Therefore, I can state that the Icom IC-7100 does not have any ALC. Of course, there is no need to overdrive any linear amplifier, however Icom engineers have probably overdone it a bit on the conservative side on this radio (?). This causes the output power to not go above approx 75-80W (PEP) as measured on my LPA-100 wattmeter in PEP mode with 14,5V DC input. This radio is known for a very conservative approach to internal ALC on the power output. I recently bought a second hand Icom IC-7100 HF radio for a reasonable price.
