I use a IC 7300 and set my mic gain up 1/3 of the way and put compression (ALC level) on level 3. I get great great comments about excellent audio quality all the time. Then tweeked the audio filters in the rig for best results with my voice. Most hams can't be bothered to do this and it sounds like it!! The desk mic I'm using is a custom built station mic I built from the standard IC-7300 hand held mic element. I cannabilized from one I got at a ham fest. This mic element is a hot electret mic and puts out a lot of audio gain. If you are setting your ALC level up more than just visible (1/3 scale) on the meter it is way too much. I built the desk mic and deep set the element into the mic body in medium firmness foam rubber which helps eliminate more background and side noise, deadens the higher frequencies, and gives the mic a smoother sounding quality. It took some playing with to get it perfect but was worth the effort.

Greit video Cal. Many operators use average reading wattmeters and in some rigs the meter is averaging as well. My FTDX 1200 is an example and CB rigs as well. So if the operator need to see the needle peaking all the time even when catching breath , bad audio is the result. It may be from a crancked up powermic or comp all the way up. So on amateur HF rig the ALC is the best meter except if there is an overdriven stage before the comp. On my TS480 high comp IN is a bad idea as on most kenwoods with dual comp adjustment. On newer rigs it seems like they are tuned to work with full tone mics so on both my FTDX 1200 and IC7300 for my voice I had to lower low frequency gain and up with high frequency gain. This must be done seperate with comp on/off especially on yaesu radios. How much comp depends on mic and if you are the sort of operator that has to be stamped on to get a sound out ;-)

It has a built in enhancer, compressor, limiter. I recently started playing around with the model 1200 by running audio from a USB mic into my computer, out thru the computer's front line level out jack to one of the two channels on the model 1200 which after processed ends up in a powered speaker. The jury is out here. Its a lot to add to the audio chain & until I actually hear my transmission my local audio testing is not really definitive. I suspect being a musician too gives you a better feel for whether I should even consider using the model 1200 in my rig's audio chain. Please feel free to add your thoughts, but right now I am leaning towards no.....

Action movies today have so flippin' large dynamics. If I turn down the volume not to wake up my neighbours when cannons are fired I can't understand the mumble speaking. If I turn up the volume to make speaking intelligibile my neighbours start banging the walls when the battery starts firing. I found a nice application. Switch Sound File Converter. With that one can extract the audio and compress it. Then I use DivX Converter to replace the original audio with the compressed in the movie. I tried a compession function of -60dB to 0 oompressed to -20dB to 0 but this results in all kind of noise being amplifeid so much that speaking is barely discernable. A slope of -60dB to 0 compressed to -40dB to 0 seems to work. Regards.

If you are running the standard IC-7300 mic, your ALC level is probably to hot. Icom mics have a lot of gain to begin with. Listen to your built in monitor through head phones and set ALC according to the best audio quality you hear without compression first. I think you'll find the ALC only needs to come up to about the 1/3 to 1/2 way mark between the bottom and the RED line max. Of course people with softer voices may need to adjust accordingly. I wouldn't adjust ALC with the compression turned on. Once you get an ALC level that sounds good, then turn on compression and readjust to you liking.
@BentConrod Жыл бұрын
The IC-7300, and I assume it's siblings also, have a meter to assist with setting compression. The recommended setting at normal voice level is between 10 and 20dB. If the meter exceeds its upper indicator distortion may occur. Transmitted audio quality can be sampled directly using the Monitor function which is very helpful in achieving optimal performance and eliminates the need to use an remote receiver such as websdr or audio reports from other operators.

@loughkb Жыл бұрын
Understanding what the 'compressor' does helps people understand the potential problem. I think. The way I understand it is. A compressor is non-linear amplification of the audio. The amount of amplification depends on how low or high the source audio is in amplitude. If you simply amplify audio linearly, you bring everything up the same amount. So loud bits are made just as much louder as the quiet bits are. This can cause the loud parts to exceed the top of the amplifiers range, clipping them off. A compressor amplifies quiet parts more than it amplifies loud parts. So it can amplify something quiet much more without pushing the loud parts so high that they clip. This 'compresses' all of the audio up toward the top, giving the overall audio more of a punchy sound. The down side to this is that room noise, background, and the quieter parts of what you are saying are all amplified right up. Muddying up the overall sound. A little bit of compression can give your voice more loudness and make it easier to understand when your signal is weak on the receiving end. Too much just makes it hard to understand you. As you demonstrated so well Cal.

@richb.4374 Жыл бұрын
Great video Callum and right on point. I hear so many terrible sounding signals on the band and most of them sound bad from too much compression. Perhaps it may not be every hams fault. If you read the manual of the Icom radios for example, they recommend running anywhere from 10 to 15db of compression. In my opinion, this is way too much and sounds terrible. 15db of compression sounds like someone hollering in your face with a bullhorn. To make matters worse, many hams never check the ALC meter and are pinning the scale on every voice peak. Even without compression, you will sound awful peaking out of the ALC range and make people on nearby frequencies mad from your splatter. Keeping compression below 10 db sounds more natural and adds that little bit of extra "oomph" you need to boost average talk power. And whether the compressor is on or off, for heavens sake watch that ALC meter too! Many hams run average reading wattmeter's and think they need tons of compression because they don't see the needle slamming the corner on every voice peak, this sounds like crap on the air, use a good peak reading wattmeter! I can hit full power voice peaks on my Yaesu FTDX101 with the mike gain at 15% and no compression. The radios power meter shows it peaking much less because it's not peak reading.

Using SDR's to sample your audio really is a great resource. One thing to note though, set the bandwidth of the SDR to equal or greater than that which you are transmitting or you will not hear a true representation of your audio. This is also one of the reasons some hams might say you sound "this way" while others say "that way", so to speak. Your bandwidth, EQ settings and uber expensive mic won't be well represented on receivers set to 300 hz low cut and a bandwidth of 2.4 kilohertz for an example.

Working contests you hear a lot of operators, and some of the audio (< 3% say) is truly horrid, and I am sure they would get better results and have more CQ returns if they sorted out their sound. Once you start clipping waveforms, you introduce harmonics all over the place.

One of the basics to always remember on sideband (obviously) is that needle has to fall back. Just with a decent meter, you can see it, set the gain (at least) so that it does and then a little under that. I found this to be a good rule of thumb if you can't hear yourself. The same may be employed with compression and processing, sure, it raises your average level, but this again is not necessarily desirable for SSB and clarity. I've found that only a small amount of compression is acceptable, in general. Of course processors vary by AGC attack time and the wave shape of those compressed, or often, clipped peaks. That's my limited knowledge on this as I do not have radios with these features, just have built and used external audio devices.

A lot depends on the type of processing with time constants being the largest difference.. Some radios have such a long release that they don’t do much for improvement with the distortion coming from overloading the audio front end.. The second problem is voice type with a heavy bass voice overloading. Trying to talk a foot away from the microphone in a highly reverberate room is also another problem,, Couple this with a bassy voice and low frequency room modes will be the worst combination.. I prefer rf clipping with steep cutoff below 300 hz with light fast (100ms) rt timed compression before the clipper… talk closely to the microphone and a dead room.. Favorite microphone being a Rode nt1.

Hi Callum, Once again, as some one from the broadcasting industry, you see this all the time. The "untrained" gets it in their head that "wind it up & it goes further". This is true to a point with AM. FM doesn't really suffer this. But this is not where the issue is here. The smarter engineers - trained in the art of "less is more". Know the limits. These "limits" come from some very suss places when you employ "digital processing" or even digital links. Which is now common place in a just about everything - including lots of ham gear. In a broadcast chain you need to watch out for compounding artifacts. But thats not the main point here either. I'd suggest the first guy in the video has either popping on his end into his mic and it's causing drastic limiting on his end. Then I'd suggest his DSP chip is about to release the "magic smoke"... something is wrong there. Third, is more with the second sample, this sounds like some one playing mp3 audio files over an SSB shortwave service. That's just a big NO THANKS! As the wishy washy that we ignore still gets sent out. There is one final thing I'd like to suggest... I can't see DSP chips in Ham gear being made at the same cost level as ones used in a $20 000 limiter box for Broadcast. Some eyeballing of how the chip obtains the Hi and Low pass filtering is needed. Filter ringing is also your enemy. Cheers buddy, Great work! 73's

@@DXCommanderHQ cheers.... I'm one that giggles when the average person says.... sounds ok to me. Because its often not.... just like fellow musicians will cringe at stuff the average person doesn't notice. And I'm not talking about taste or preference. Just pure quality and how close it sounds to the real thing.

Contests are the best time to hear dreadful modulation. Some stations are firm believers in using ACFC(All Controls Fully Clockwise) thinking this will get them the contacts. If only they'd make use of WebSDR to monitor themselves. Some of the early audio processors built into rigs could be a bit grim, but with modern rigs there really is no excuse for sounding like a Dalek with a mouth full of porridge.🙄73 Gareth GW4JPC

Nice. But does one really need a websdr station? I've done the same by using my own SDRplay receiver listening on a short rx antenna while transmitting into a dummy load and while adjusting the controls for the optimum mic gain and processing level. While recording, I just read out the adjusting knob's mic level and/or the processing level settings as my test message. Then on playback, I write down the optimum settings for each microphone and put a sticker on them so I won't forget them. However, using a websdr station does have the advantage of telling one how well a weak, but processed, signal gets through with real-world interference
@DXCommanderHQ Жыл бұрын
SDRs are free but of course you can use a dummy load. I suggest though not that method. I tried it with not so good results. My radios were obviously too close together and rig #2 didn't like it.
@johnkiljan7441 Жыл бұрын
@@DXCommanderHQ, yeah I had that problem too when first trying it -- too much overload. When I separated the SDR receiver by 50' from the transceiver's dummy load, the S-level dropped down to something reasonable and I could do the voice quality tests.

This is not just serious over-compression, the audio sounds highly distorted, with a bunch of Echo and distortion! It might be the addition of an external audio processor, with a VERY SERIOUS level of audio LIMITING!!! Which can add a bunch of distortion, if turned up too high!!!
