If you're running the DSP then there can be sound artifacts introduced into the audio. If the noise is present without DSP then you might want to look for an external noise source or change power supplies to see if that clears it up.
The DSP is always running, no? I've tried every possible filter and NR setting, but I still hear the artifacts (pops, clicks, etc.) on CW. I've heard other Pro3 owners (CW enthusiasts) say the same thing about the Pro3 over the years. Icom has not been able to rid it of discernable CW artifacts. When you receive CW on SSB, you don't hear them!
Nice video! Just got my Pro3. How do you get the band scope center line red (or any different color) like you have, for more visibility? Also, what is the best setting for normal SSB - 'comp on wide', 'comp on mid', or 'comp on nar'? Thank you in advance!
The voices sound strange because a ham radio transmission like this transmits only one copy of the signal (the lower sideband in this video) without a reference carrier. When you tune a regular AM radio, the radio signal is filtered to select one station, then rectified to bring it to the audio range. But with this, there is a beat frequency oscillator (VFO) to 'shift' the RF voice into the AF range by heterodyning.
how do you like the 756 pro II?

Are the 'snaps, pops, and crackles' on CW receive normal? Never heard these on my older analog rigs.

You get the red line by turning on the XMIT MARKER.

Thank you!!! What about SSB settings, 'comp wide', 'comp mid', or 'comp nar'? What is the difference?
sophiegromit 3 years ago
Those three settings WIDE, MID, and NAR set your transmit bandwidth. The COMP just means the speech compressor is enabled.

As for settings on my rig:
WIDE(L)=100 WIDE(H)=2900
MID(L)=300 MID(H)=2700
NAR(L)=500 NAR(H)=2500
You can set it anywhere you'd like but that's how mine is set. I normally use WIDE or MID and always use compression with my Heil PR-20 mic.

another nice 1, what antenna are u using for 40m?
eibeer 3 years ago
Just a inverted vee antenna ,apex up at 30ft.
The antenna is resonent on the 40mtr band.

And for some reason the 40 meter Band is dead here in the NW US! Blast It!
