Icom IC-7610 Digital Pre-Distortion [DPD] short demonstration Firmware v1.40 

Check the link in the description. I just updated it. Use at your own risk. It's from the Japan site.

Don't just like the post, answer the question. Thx.

Less splatter, cleaner signal from your transmitted signal.

The 7610 has great audio without this feature. In some cases though there can be distortion and this will help smooth that out to make the signal the clearest possible before your amplifier. 73s.

@@HamRadio200 thanks 73s from Rotterdam,

I presume that this feature is to improve transmit intermods, to make them better than about -30dBc. I'm not sure that would make a discernable difference to the tx audio; I think the intention is to reduce intermod products outside the nominal tx passband so that interference, with freqeuncy-adjacent stations, is markedly reduced. But I would be interested to know whether I am correct. I wonder what the v1.40 firmware notes have to say about this?

I am not aware of that because I do not use that port.

With the link in the description you can download it from the Global/Japan site. Thanks for watching.
