I used to be a big Yaesu fan, I had some older stuff by them that I considered great radios, however it seems that for a few years now the quality has slipped off the top tier.
When you start feeling like a beta tester with a new radio it's not a good thing.
They have never failed to finally fix a problem, but I don't want to have to keep sending radios back in for service starting the first week of use.
I hope they solve the problem with your radio.
Best of luck.

after 3 trys they dont get er right im at the point of NO MORE YAHOO RADIOS

Digital Noise Reduction works great on the 7300.

after setting 2 it starts sounding like the guy is talking down a toilet roll,
after setting 4 its sounds like the guys is talking down a tube with socks stuffed in his mouth with some weird phasey strangeness going on,

unlike the other vid where dsp did greatly improve redability this vid is a good example of why i don't like dsp.

my ears have no problem with the setting on 0, its noisy but that's where the guys voice sounds more natural, that dsp on that guy is not improving his readability to me,
just spoiling his audio,
i can do without everybody sounding like Jacques Cousteau.

I would have thought out on the road QRM and noise floor would be non existent. Unless your truck is QRMing your radio.

1). Sticking my neck out is in regards to radios not in discussion in this sub-forum. Thus, this last post on the subject.

2). Being mobile is a different animal than being stationary.

3). Intelligence received is actionable.

— Problems with noise both external and internal to the truck are constant. “Relief” can be temporary. (Passenger vehicles have a similar problem set, increasingly bad with every new model year; all-electric vehicles are said to be well nigh impossible).

— A more sophisticated radio sold for Eleven-Meter use with features associated with Amateur Equipment “might” change the parameters of the statement that, DSP is a necessary addition.

In the meantime, DSP so very much changes the experience of mobile use (and I’d strongly suspect this true with portable/mobile Amateur gear) that it’s much a matter of use.

So, (with respect),

— Where RX is not to a fixed pattern of words;

— Where information (intelligence) determines one own actions;

— Where “legibility” has become crucial;

Any aid — at all — is overwhelmingly an asset.

“Quality” is dependent on the users expectations (desires lower order than needs), in transceiver capability.

I’m not in this thread to offer debate, troll, or be contentious. Again it’s back to the thread title. “Perceived Limitations of DSP”, would be better, IMO. (“Quality-On-Offer”, appears to be the sub-title).



Now back to your regularly-scheduled programming.

I would say it sounds ok, no warbling but it kind of kills the mids in the voices, they sound a bit more muffled/nasl. Anyway ultimately you as the operator is best positioned to judge what level you use it at. It seems like it is worth having.

@Slowmover I am not entirely sure I understood what you mean fully but I understand you are a fan of DSP NR when on the move

I am not well placed to say more about DSP NR in amateur transceivers so I won't !

I use a Clearspeech DSP speaker in my Jeep with the IC-7000. I've found a combination of using the Icom IF DSP in conjunction with the Clearspeech AF DSP speaker that has allowed me to pull out MANY contacts while either mobile or stationary portable (usually while camping or hunting) that I would not have been able to hear with a compromise mobile antenna. Not to mention how much it gets rid of hard-to-hunt-down engine noises. The problem that the DSP combo helps in this setup with is the alligator station problem - I can run about 500 watts which will usually cause them to hear me, so I need every tool I have to also hear them.

The Elecraft KX3 has the best DSP I have ever used in a rig...and I've used a few. It is better than the Elecraft K3S by a mile IMO, mainly because you can adjust so many different parameters of the algorithm in the setup to get it so behave the way you prefer. I've never cared much for any Yaesu DSP implementation I've tried, although I have not yet tried their newest high end rigs. I can usually find a setting on most Icom HF rigs I've used that I like...but nothing compares to the KX3 in my book. I haven't had the opportunity to play with a Flexradio rig yet.
