Here you can see how small are those SMD diodes:Īfter you have removed diodes as shown on above pictures, return the DSP-module, return the botom cover into its place and turn on the transceiver. Carefully (using a magnifying glass) you should remove the diodes located at the PCB as shown on the picture below:ĭiodes are very small, therefore this procedure should be done with great care Other manufacturers microphones have different pin. The place where diodes which have to be removed are on PCB under DSP-unit. 7-pin DIN plug with Pins 6 (XVRT) and 7 (+12V) bridged via 27K 0.25W resistor, plugged into Pro III ACC (2) socket to activate XVERT mode.Pro III set to 28100.000 kHz, RTTY mode. 2 hours ago Use Icom microphones only (supplied or optional). Please compare the menu settings to the ones I have provided here for the ProIII. If and when it is replaced it will be with a 756 pro III. The radio was bought at a good price and is my main radio with a IC 7100 for digital/ VHF and UHF and a Yaesu 450 D for 6 meter and back up. The IC-756Pro III provides a selectable mini-scope display mode.
This latest version offers some incremental improvements over the previous 756 Pro II: The IC-756 Pro II spectrum scope display occupied the lower half of the screen.

Carefully unplug DSP-unit and place it aside:Īfter removing the DSP-unit, you can see the SMD diodes which have to be removed. Icom 756pro and IC-756proIII radio setup (the set up for the Icom 756pro and 756proIII are the same) Introduction - Whiles these instructions were developed from the Icom 756proIII manual they should work for all Icom 756xxx radios. I am happy with this rig It has had one line in the display that comes and goes. The Icom 756 Pro III was the last member of the venerable 756 family that started with the 756, 756 Pro, 756 ProII. There is DSP-unit (plug in metal box) on the right side. (click on the picture above to view it in high resolution) Place the transceiver on the table with face toward you, upside down. This modification allows transmitter to transmit on whole frequency range. Transmitter is factory limited to transmit on amateurs bands only. It can receive from 30 kHz up to 60 MHz continuously and transmit all mode, all bands with 100 watts RF power output. Operation is sub-ject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. ICOM IC-756 Pro2 is popular HF+6m band transceiver. INSTRUCTION MANUAL HF/50 MHz ALL MODE TRANSCEIVER This device complies with Part 15 of the FCC rules.
