FL-430 Filter (Discontinued) 6kHz 1st IF filter for HF/6M band Both the Icom IC-9100 and IC-7410 transceivers come with a built-in 15kHz 1st IF filter and can accept up to two optional filters (3kHz FL-431 and 6kHz FL-430). By changing the first IF filter width according to the operating mode, the desired signal is protected from adjacent inband signals at the later stages.
The IC-7410 from Icom has been designed as a specialised HF/6M transceiver sporting excellent performance and features. The IC-7410 employs a high grade DSP unit and double conversion super-heterodyne system developed from the latest technology found in higher grade Icom rigs including the IC-7600, IC-7700 and IC-7800 series. In addition, the IC-7410 has a built-in 15kHz 1st IF filter and can accept up to two optional filters (3kHz/6kHz). When operated with these 1st IF filters, narrow mode signals such as the CW and SSB modes are protected from adjacent and unwanted strong signal interference.
The IC-9100 all-in-one HF/VHF/UHF transceiver covers not only HF, 6M, 2M, 70cm and 23cm* Amateur radio bands, but also a variety of operating modes including SSB, CW, AM and FM. It also features dual band simultaneous reception, satellite mode operation and RTTY decode on the display.
