Listening fatigue IC 7300
« on: December 01, 2020, 08:09:25 PM »

I have my radio on more and more with conditions improving. I found myself a little distracted by the constant hi end static the swirling sand paper kind of background sound.
I also have a another Anytone radio that has a hi cut selection and I always have on as its much easier on the ears.
So now I have the treble on ssb receive slighly above mid point and the bass is pretty close to the mid point. I use the noise reduction
at 5-6-7.
Just to add reference to my sound preference, The broadcast radio in my car for "voice" sounds so much better with full treble and no bass.
So, the point of my post is to find if others have found a way to make adjustments to the audio parameters, there is and treble and bass control and then the other pass filters.
At this time I was using the internal speaker, at another point I also use an external with a larger diameter speaker. TIA
Hope KOUA reads this, pretty sure he"ll find it.

I'm not sure what the question is about your radio. My 7300 speaker output drive a Crutchfield 160 watt amplifier into  Polk SRS reference speaker. Audio sounds fine.

I just happened to notice how much hi end noise I have, even with a good signal. I experimented using the noise reduction, and tone controls, I was hoping that using the filter setting instead of the  tone controls might give me a warmer softer audio, hoping that there is a better setting that might calm down the audio.
AS I made these comments  I was using the internal speaker, maybe that's half the problem.

My 7300 is a keeper, however I too notice a lot of noise especially on 40 and 20 meters. I've found I keep the NR on all the time. I've owned several ICOM HF rigs and this is the worse rig for noise. And yes I run the RF gain down as well. My 751A was much quieter than the 7300.

When I get tired of the noise, I switch to the Elecraft KX3 and all that extraneous noise is gone.......some days I wish I had kept my K2/100........oh well

Having both the IC-7600 and the IC-7300 I notice the same issue especially while using head phones.  Both radios have the "twin pass band tune" adjusting knobs. Grab the "outer ring" knob and rotate it a few notch's counter clock wise to find tune the audio. I find that this simple adjustment cuts down the noise but will in most cases improve the sound quality on SSB.  Works well on CW as well. Simple try and if your not happy, just reset the knob, no damage done !   Mike W9KY

I'll second that. My Jupiter stayed on most of the day. What a pleasant rig to listen to.

They do, it is called a Yaesu FTDX101. Icoms are known for having "harsh" RX audio, having owned many Icoms I would agree with that assessment.

The FTDX101MP has very pleasant none harsh audio. The RX audio difference between Yaesu and Icom is remarkable.  In fact by skillful use of the FTDX101's various bells and whistles (especially VC tune) the CW sounds like a code monitor and SSB sounds like 2 mtr FM....

I am sure K0UA will be here shortly to defend his beloved Icom 7610 audio.  :D :D :D

Funny you should say that. After many Icoms I went back to a YAESU FT-950. I'll have to get to HRO and see what the new 101 sounds like. Interesting number choice; Radio 101...

And this is why I chose the Yaesu FTdx3000. The 7300 has lots of bells and whistles, but it is what it is: a compromise, ultra-compact radio with the inherent problems ultra-compact systems have. My FTdx3000 was bought for one main reason and it's not the close-in signal handling capability, although that is astounding. Best in class. I bought it for it's 'tube sound'. It truly does sound like a warm, grand old vac tube rig- and this is with the internal speaker. It is truly amazing.
But I connect it to a homemade speaker - and the sound becomes a new experience entirely. Bass that I can feel. Room filling deep warm audio. Not a bit of hiss or anything tiring to listen to. My speaker is the bass driver from a 100w PC gaming speaker system. I just used the bass driver in the wooden box, stuffed it with old tee shirts, etc.. and it's the best sounding audio I've ever heard in my 46 years as a ham. It's truly remarkable. I paid ten bucks for the PC gaming speakers at a thrift store.

That is why I like the Flex radios, super audio, and you can limit the response to whatever you want, on both TX and RX.
If you do not want to hear anything over 2900 Hz, you can turn it off.
You also have a 10 band EQ, or even a 20 band.
If you want 20 to 5000 Hz for SWL or broadcast, or the AM guys you can have it.

The audio output is clean.
No other rig gives you such control and good audio as a good SDR like the Flex and Anan.

I have a TS-990S (expensive!) so that gives me a lot of flexibility.  At my age, high frequencies don't have much significance!  Setting the band pass to 2200 Hz, (sometimes 2400 Hz) cuts much of the annoying high audio frequency noise.  Also using the 2.7 kHz filter helps a great deal.  Switch-selected audio filter also helps.  Have an SDR radio in a 2019 Honda CR-V -- not impressed, AT ALL, with non-Ham targeted SDR radio!  Not surprised that Sirius XM is almost a mandatory option -- despite loss of signal with heavy tree leaf cover and road cuts!

I have a 7300 for my motor home and compared to my TS-890, it has a higher background noise floor but it's still a remarkable radio at a third of the cost of the other radio. 

To mitigate the background hiss, I simply set the NR on the 7300 to a setting of "3" and that background noise disappears. I have left the audio settings of the 7300 at the the factory points.

Of course, there are external passive audio filters and filtered speakers (BHI, West Mtn Radio, etc) that would accomplish the same outcome but the NR set at a low point accomplishes the same thing and doesn't adversely affect the audio characteristics of the received signal.

Some years ago, I picked up a pair of KEF Coda speakers second hand. They sit on the shelf above my shack desk - one connected to the 7300 and one to the Yaesu FTM-400 - a great improvement over the internal speakers in both cases.

Another adjustment is to set your filter skirts to soft instead of sharp.

For the "baiters", why would I "jump in to defend"?  If you don't like the way your rig sounds, then adjust it till you do. And if you still hate it, then sell it.

I think both my 7300's and my 7610 sound great. I adjust them until I am happy with them.
