1. [RFI] RF Feedback - FL7000 AMP (score: 1): Author: Tony <dxdx@optonline.net>; Date: Wed, 19 Aug 2009 03:51:29 -0400; All, I have what seems to be a unique situation with a Yaesu FL7000 solid state amplifier. The protection circuit trips for no reason in SSB mode, but works fine on CW and digital modes. The protecti; /archives//html/RFI/2009-08/msg00006.html (6,673 bytes)

The FL7000 is super touchy on overdrive in SSB and you need to do the mods to desensitize the protection circuitry. The unit I have, it was imposible to get near rated; /archives//html/RFI/2009-08/msg00008.html (8,029 bytes)

It doesn't trip at all now even when I forget to se; /archives//html/RFI/2009-08/msg00009.html (9,489 bytes)

My two FT1000MPs have a pin 1 problem at the mic connector that causes RF feedback on 75M and 15M. Measurements of that pin 1 problem show a broad peak around 5 MHz a; /archives//html/RFI/2009-08/msg00010.html (8,151 bytes)
