The IC-280 works fre~uencies in excess of the 2 meter band with ICOM s outstanding single-knob tuning, so you can listen around the,entire band without fooling with three tuning knobs. KV5R's Icom IC-706MkIIG Mods and Tips Page Icon radios seem to use the ALC circuit to control power output. It provides reliable matching of frequencies from 3. All Yaesu transceivers are set up to use low gain, passive dynamic microphones into their high gain microphone preamplifiers. Tuning the IC-718 for distortion-free AM is the same on any band. For this, we use the FT-8800 dual band VHF/UHF transceiver However, there may be a need for longer distance communications. Now while the ALS-600 provides your basic amplifier features, new. No adjustment is required when the ALC output level of the connected non-Icom linear amplifier is 0 to -4 V DC. Yaesu Ft-600 Operating Manual The FT-470 is an ultra compact FM hand—held providing up to five watts of RF power on the 2m and Please read this manual carefully to gain a— clear understanding of the features of the. With the superior performance found in the IC-718 such as wide dynamic range, high signal/noise ratio, and full duty operation you will find making these contacts easy. exceeds the allowable level, the ALC limits the RF power. On the icom ic-718, this means pressing SET to switch the meter to ALC, then backing off the Red dial on the Digimaster until there's no bars on the ALC. The only adjustments for ALC will be done on front of the amplifier. So, now it's been over two years and I finally add something new. HOWEVER, the Mic Pre Amp on the iC 718 has down in gain by -15 dB. All you need to do is delete your "icom.
