Re: IC7000 tx audio

Mark Chalkley
 

Chuck,

I don’t disagree - I think the operative word is “need”.  I’ve been an “audiophile” for decades:  For many years, I was able to tell vinyl from any form of digital with near 100% accuracy on any system.  (I could even tell vinyl that was originally digitally mastered vs. analog-mastered vinyl, so much so that none of my 3000+ records are digitally mastered...)  Digital music causes fairly rapid mental fatigue for me (I even have a hard time with most solid state amps - so tube audio systems are my thing), no matter how high the sampling rate, etc.  That’s lessening as my ears age, but it’s still there, and I’m not bragging - it’s been more a liability than anything else.  I sure wish I had all the money I’ve spent over the years compensating for hating the sound of audio that most people found completely acceptable, if they could even tell the difference...

You may be wondering how my ears react to DSP, and they answer is “not well”.  I have to leave DSP-based filters off mostly and turn them on only for stuff that has to be dug out of the mud...

Anyway, at one point, not long after I got my license (& the IC-7000 the same day) I heard transmitted audio that a contact I’ve long since forgotten A/B’ed for me: he’d gone into his stock mic, drilled out the hole a bit, realigned the element, etc., then bought a second and had Bob mod it.  The difference to my ears was significant enough that I don’t think I completely believed it, so I went with an MXL studio mic with Prosonus tube processor instead.  I had a LOT of contacts, upon hearing my audio, say there was NO WAY I was using the stock mic, and they were right, of course.  I even had quite a few who I’m pretty sure didn’t believe I was running a barefoot IC-7000 (but they were wrong).

At any rate, to your comment, I do believe that the worst of most of the HM-151’s issues can probably be aided considerably by realigning the element and opening up the hole a bit.  Nagy (a really really nice guy, btw) says on his site that this is necessary and something he does by default.  But his custom-made element (he was a broadcast engineer by profession) takes it to another level entirely.  I don’t doubt that generally, the difference between a re-aligned stock element and Nagy’s won’t be obvious except on FM and SSB under good conditions, but I do also think the improvement in “punch” and intelligibility helps considerably in tough contacts and pile-ups.  As I said, just my $0.02 worth, and you can tell from the above that I’m not normal, so most everyone else’s mileage WILL (not may) vary...

My $.02 worth is that you can’t go wrong with the IC-7000, and if you let him mod your mic for you, you’ve got one sweet setup in a very convenient & easy-to-use package.

If you have a mid-range voice, only the Japanese versions of the HM151 have the problem.  The later Chinese made mikes are fine with an average voice BUT you must use the TX equalizer in the radio’s menu to boost bass and mid-range while cutting highs.

The exact settings have been listed before and, as my rig is in my mobile, I can’t tell you at this moment.

Thank you for the replies much appreciated.  If I were wire the audio to go in through the ACC socket , would I be best to wire a PTT through the modular Jack? 


Re: Studio mic and external audio chain ?

Gene Horr
 

Once you have the mic gain set, then you can turn up the compression just a little. You really don't need much.
That's my experience. For SSB once you have the basic settings correctly configured one isn't going to make a material improvement by changing microphones, adding an EQ, signal processing, etc. Something Jim mentioned that I would stress is SNR can be far more important. Make sure the microphone is only picking up only your direct voice at an appropriate volume. The more gain you have to use the more the microphone is picking up sounds other than your direct voice.

Re: Studio mic and external audio chain ?

Jim Szalajeski
 

I have been around a long time and what I notice is that many HF operators take little care to insure they are not splattering their audio all up and down the band.  You do not need very much compression at all to have a good punch to your signal.  But too much again and the room background noise starts to be picked up. 

The best way to work on your mic gain and compression is to take a second radio and use it to listen to yourself.  Pull the antenna off of it so your not over loading it.  Use a set of headphones and listen to your signal. 

The first step I use is to work on the audio gain.  As you move away from the mic, you should start to notice your voice level go down.  I use a distance of around one foot where my voice drops off significantly. This way the room background noise is not going to be very loud at all.  If You anything like me, I have a number of public safety radios going as well as several ham radios on the local repeaters.  The more you can keep that stuff off your HF radio, the better your signal will sound. 

As for the compression goes, that is a sore issue with many people.  The compressor is designed to keep your audio at about the same level.  If you talk softly or loud, the compressor is like an auto audio gain control.  It tries to keep your voice at the same level all the same. 

Is the compressor starting to sound like an audio gain control?  If you said yes, your right.  So now maybe your stating to see the confusion popping it's head up over how to set the mic audio and set the compression. 

My best comment is to turn off the compression setting and start with the mic gain.  Once you have the mic gain set, then you can turn up the compression just a little.  You really don't need much. 

Now you should be ready to try an on air contact and see what your contact says about how your audio now sounds.  Using a friend that you have regularly talked with is a good place to start.  See what they say about your audio now.  Bet they like it much better.  The other users of the band will like you also because your not being heard to splatter 30 Khz away or more. 

Try it and see how much better your signal sounds. 

Jim

FWIW --

I haven't played with the IC-7000, but I _have_ played with my Yaesu FT-450, using both a Shure SM58 dynamic mic, and a Behringer C-2 small-diaphragm condenser.

I ran the C-2 through a Behringer VX2496 "vocal chain" (no longer produced) -- preamp / expander / compressor / EQ /.  I ran the Shure SM58 straight into the FT-450.

I set up the VX2496 for "contest audio" -- reduced the bass, put on a heavy "presence peak", used a lot of compression.  Using the C-2 condenser mic (which has flat response down to 50 Hz or so) It sounded much like a contest rig with a Heil HC-4 mic.  

The FT-450 has fairly narrow transmit bandwidth, and a built-in 3-band "transmit equalizer" (with a "low-cut / high boost" setting):

Running the Shure SM58 straight into the FT-450, using the FT-450's built-in TX EQ and compressor, gave almost the same effect, and equal average transmitted power.  That became my standard setup.  

The SM58 is an "industry-standard" mic (in the music industry) for good reasons:

. . . It has decent "pop-and-hiss" rejection (if you want it "pop-proof", put a $5 foam ball on it)

. . . It seems to suit a lot of voices, and you can control bass boost by moving toward, or away from, the mic;

. . . It's physically tough, and lasts forever;

. . . It's not very expensive (around $100 US).

The IC-7000 lets you vary the TX bandwidth and center frequency.  My experience with those controls (using the stock mic) is that you can increase the "low-cut" TX frequency (reducing the bass) without distorting.  But you _should not_ reduce the "high-cut" frequency -- leave it above 3 kHz.

Before you play, read Heil Sound's "All Things ICOM" web page.  You'll find what you need to know about blocking capacitors, and using the "COMP" feature to give enough mic gain to let you use a dynamic mic like the SM58 or Heil PR-781, on the IC-7000.

Ah Helmut....well no you didn't miss it as I discovered the answer, and as no reply was posted I decided to remove the post rather than bother the forum with what turned out to be my lack of properly investigating the issue.

Under the Quick Start menu, the sub menu Display option, item 19, are 3 options labeled 1,2 and 3. The first option produces the black and white result while 2 and 3 produce colour. Interestingly the Instruction Manual only mentions options 1 and 2 and talks about image size. There must be other stuff happening to cause the colour to change. I can not find any reference in the Service Manual.
