Setup for the Icom 756 Pro III

Transceiver settings

When setting up most new DSP transceivers, there is usually an internal EQ that must be considered when setting up any external audio gear. In the case of the Pro III there is in fact a small section that has EQ type settings.

First thing to do is  you must make sure that you press the last button on the row just to the left of the screen until it reads comp off wide. When you want the rig to sound its best audio ways, you must always have the rig in this general mode, wide with the compressor off. 

Then press the EXIT/SET button until you get the mini display on the screen and then hold the EXIT/SET button until the set menu comes up. Press F-1 to get the level set screen up. Press F-1 again until you get to the TX Tone controls. Default for both the Bass and Treble sliders is 0. If you are not going to put external EQ equipment on the rig, adjust these sliders while listening to the monitor until it sounds as you like. Press F-2 now until you get to SSB TBW (Wide) L and set that to 100 by rotating the main tuning dial. Press F-2 one more time and adjust SSB TBW (High) H to 2900 by rotating the main tuning dial again. The rig will now be set for its maximum bandpass of 2.8Khz in the wide mode as set above. Do the same thing to set the medium and narrow settings as you like. 

Now press the EXIT/SET button to get the mini display up and then press the Filter button for about 1 second until there is a picture of a filter spread. Continue to press the filter button until the Fil1 is selected. While pushing the BW button (F-1) turn the main tuning dial until the Fil1 says 3.6K. Now the radio is setup for as wide as it will go. Now if you are not going to have external audio gear connected, you are ready to go. You may want to go back and adjust the internal EQ Bass and Treble sliders again to touch it up a little. 

External audio gear

As I said in BACKGROUND, I will only describe the audio gear I use on the Pro III, not some gear you may want to use. In that case you are on your own. The main audio gear I use for the Pro III is the Behringer 2496. A description of how to use this particular device is on other parts of this page and I am not going to duplicate that write up here. I use the GEQ, PEQ, DEQ, and DYN. Of course I use the other sections of the 2496 but I will not talk about them here as again that would be redundant. 

Here is my setup for the Pro III. I use the GEQ settings with these setup. The Freq. are not in order but in the order I added them when I was getting the sound I wanted.

Here is my current setting for the GEQ.

Table of setup for the DEQ   

The DYN is the downward expander and has to be set as per your microphone and the amount of ambient noise in your shack. My own settings are Gain = 0.0, Threshold = -27 db, Ratio = 1:2:5. On the second page the parameters are as follows: Attack = 3.91, Release = 20.0.
