Uses a fundamental-type SMD monolithic crystal filter as the first roofing filter. The strong-signal performance of the mixer and its peripheral circuits is greatly improved. This feedback will increase the 3rd-order intercept point and IMD3 dynamic range without loss of sensitivity when Preamp 1 is engaged.Įmploys new quad-JFET first mixer. This is a noise-free negative-feedback circuit for Preamp 1, which improves linearity at the expense of power gain, without degrading noise figure. Uses a low-noise feedback circuit for Preamp 1. Refer to 1.1 below.Įmploys new diodes and coils in the RF BPF to decrease strong-signal IMD. (5 assigned channels open on USA version band can be enabled on other versions with modification.)Īchieves IP3 > +30 dBm (14MHz band standard value). The IC-756PRO III will incorporate some IC-7800 technology:ĥ MHz (60m) band standard on all versions. The IC-756Pro III incorporated the following changes as compared to the IC-756Pro II: 1. Icom unveiled the new IC-756Pro III at Tokyo HamFair 2004, which took place on August 21 and 22, 2004. The IC-756Pro III received FCC certification on Septemunder FCC ID AFJ217800. See Dave, N9EWO's Radio Receiver Page (link below). New product information from ICOM The IC-756PRO III Hot News! The IC-756Pro3 has been discontinued as of late January 2009.
