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. There are two published mods that are possible on this radio. Icom IC 7100 Modification Low power output on SSB - Modification ICOM IC 7100 SSB - Antenn TX RX Publicado el 25 may. The new IC-7100 is a compact all-mode transceiver with a redesigned slanted touch-screen display and comes standard with. 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.
