![]() Auto tune antenna - touch tune button on any MFJ-939I/K/Y for any rig. Super Versatile! Works with ALL older rigs, classic transmitters, Flex, Elecraft, Tentec, QRP, others. If you get a new transceiver, simply order a new Plug and Play cable. Super Versatile Truly Plug & Play! No settings, only one cable to plug in! Order MFJ-939I, Icom MFJ-939K, Ken MFJ-939Y, Yaesu. Safe, reliable, continuous 200W SSB/CW.Īs Small as Your Radio Tiny 6 1/2W x 2 7/8H x 8 3/8D”. Heavy-Duty Components Heavy-duty L-network: 10 Amp/1000V relays, RF duty silver mica caps won’t burn up. MFJ`s faster speed comes from advanced technology and software algorithms not from fewer solutions.Īudio SWR Meter An Audio SWR meter beeps when SWR 3. ICOM IC-7300 Reviews Home Reviews For: ICOM IC-7300 Category: Transceivers: HF Amateur HF+6M+VHF+UHF models - non QRP <5W eMail Subscription Registered users are allowed to subscribe to specific review topics and receive eMail notifications when new reviews are posted. That`s 4 times the 32,768 solutions of competitors using only 128 L/C values each! Don`t be fooled by competing products claiming fast search times - if you have a quarter of the matching solutions, of course,it takes less time to finish but it`s not faster. You can use an antenna switch to select up to 8 antennas and assign each antenna its own 2500 memories!Ĥ Times More Solutions and Faster! MFJ has 256 values each of capacitance and inductance for 131,072 matching solutions giving you a finely tuned very low SWR. ![]() MFJ VirtualAntenna Memory MFJ exclusive VirtualAntenna Memory system gives you 8 antenna memory banks of 2500 memories each. If so, tuning is instantaneous and you’re ready to go! InstantRecall InstantRecall first checks its memory to see if you have operated this frequency before. Others search slowly through all solutions. Measure & Compute = Instant Match MFJ-939 uniquely measures your antenna’s complex impedance (R, X), computes the L-network and snaps in needed components for instant matching.ĪdaptiveSearch AdaptiveSearch determines a sub-set of all solutions that can provide a safe match and searches only that subset giving you an ultra fast match. Highly intelligent, ultra-fast tuning! As you’re ragchewing, contesting or DXing, the MFJ-939 is learning your antenna and the way you operate and storing all this in its 20,000 memories. Matches 6-1600 Ohms (SWR up to 32:1) - that’s a 50% wider matching range than competing products that are less capable and higher priced. Tunes your coax fed or random wire antennas 1.8-30 MHz from 2 Watts QRP to full 200 Watts SSB/CW. MFJ-939I/K/Y automatically tunes your antenna as you tune your radio. Plug & Play! You won’t even know it’s there. The superior Phase Noise characteristics reduce noise components for both receive and transmit signals."Includes cable for use with any ICOM radio that supports the ICOM AH-3 or AH-4 tuner, including: IC-706 series, IC-707, IC-718, IC-725, IC-728, IC-736, IC-738, IC-746, IC-756 series, IC-7000, IC-7100, IC-7200, IC-7300, IC-7600 and IC-7610. The IC-7300’s RMDR is about 97dB * (typical value) improving the Phase Noise characteristics by about 15dB (at 1 kHz frequency separation). Then processed in the FPGA (Field-Programmable Gate Array), making it possible to simplify the circuit construction as well as reduce noise that can mask weak signals. The Icom IC-7300 employs an RF direct sampling system, where RF signals are directly converted to digital data.
