I then set the ALC on the IC-PW1 amplifier and I was ready to go just after 0001Z on the 22nd. I had to route DC power to the PRO III since the ‘775 has it’s own internal power supply. When I got home, I disconnected all the cables going to my IC-775DSP and replaced it with one of the PRO III’s in a matter of minutes. I had already made a questionable SSB QSO and a good PSK31 contact, but a solid SSB and CW contact still eluded me. With the VU4 DXpedition underway, I was anxious to get the radios home and in a more quiet environment to try to work them on CW. The first thing I noticed was how well the noise blanker and noise reduction functions worked. Since my office is located in an industrial park, there is a lot of noise.

Everything was quite well laid out, the manual was informative and operation of the radio was quite easy.
In a couple of hours, by going through the manual and testing the different functions of the radio, I felt comfortable with it right away. Since it was the week of Christmas, it was slow enough to allow me to unpack one and connect it to the Cushcraft A3S tribander I have on a 50′ tower at work. And he did – two new PRO III’s which arrived on December 21, 2004. When I told him “Kenwood”, he asked “What do we have to do to get you to run Icom radios?”. After several consecutive winning efforts in the NAQP RTTY event, Ray asked me what kind of radios I used. Ray is heavily involved in Icom’s award sponsorship for the NAQP RTTY contests held in February and July each year.

INFOĬI-V Level Converter for connection to PC RS-232C port. Screen saver function to prolong LCD life and reduce burn-in.Īutomatic antenna tuner 120 watts, 80 to 6 meters. This permits the operator to configure his own custom WIDE/MID/NAR selections by mixing and matching low and high roll-off points.Ĭlock function displays local time and UTC time with time difference indication In the IC-756Pro III, it is possible to program each of the three settings individually with the following preset cutoff frequencies: Lower -6dB point: 100, 300 and 500 Hz., Upper -6dB point: 2.5, 2.7 and 2.9 kHz. The lower and upper -6dB points of the transmitted audio-frequency response are fixed for each setting. The IC-756 Pro II provided three selectable TOBW settings: WIDE/MID/NAR. The new symbol is provided even with the memory keyer enabled. Preamp changed to a noiseless feedback type to reduce second order distortion. Improved 1st filter and BPF for reduced distortion This allows simultaneous display of the filter, memory-keyer and other menus along with a half-size spectrum-scope display. The IC-756Pro III provides a selectable mini-scope display mode. The IC-756 Pro II spectrum scope display occupied the lower half of the screen. Real time spectrum scope (with mini-scope) Improved Third Order Intercept point of +30dBm This latest version offers some incremental improvements over the previous 756 Pro II: The Icom 756 Pro III was the last member of the venerable "756" family that started with the 756, 756 Pro, 756 ProII.
