Yaesu FT-991 upgraded to FT-991A

The Upgrade

I received my FT-991 back from Yaesu in the form of an FT-991A. They do not replace the front bezel, but the radio has a new sticker on the bottom showing that the model is a FT-991A and it has a new serial number.

I’ve attached a video of the radio in action, and also I demonstrate the new Digital Noise Reduction function. I had read somewhere that the FT-991A had an upgraded DNR and upgraded DSP functionality. It does seem effective, but I can’t decide whether I like it or not. I’m sure I’ll get used to it.

Anyway, I’d like to say thanks to Stephanie at Yaesu for all of her help, the contact, and the service. I’ll likely update this post as I get more experience with the FT-991A.

  1. Dunno man – guy’s voice popped right out when you hit the DNR button. ¯(ツ)

    • True that. I’ve got a couple of days playing with it now, and I have to say it’s really very effective. An improvement over the previous version. There is a certain swishy, underwater artifact-y noise which accompanies the DNR audio, but if you can get past that, it’s useful.

  2. On VHF FM I can’t turn the DNR on ! It only allows DNR on other modes like SSB . Am I doing something wrong ?
    Thanks Graham
