Hi,
The main board of IC7000 was sold ,any way PA unit ,DDS unit available, interested people can contact me ,you can use for spares or donor for other icom ic7000 radios  ,the above units were taken from radio which was  expensive to service ,so please be noted these parts are AS IS and for parts only,
thanks

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.

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.

Have fun --

Re: Video out problem

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.

Re: IC7K locked up

Charles Scott <cscott@...>
 

Joe:

So far so good. I'm still getting used to some of the differences between the radios, but for the most part the controls make sense.

The cool thing about it is that the control head fits snugly and securely into the pocket (if I can call it that) at the front of the console in my 2014 RAM 1500 without any mounting hardware. I'm still contemplating where to put the control head for my IC-2820 since that was somewhat displaced by the 7100 control head.

On the air it's pretty much flawless. The only thing I find curious is that I put in an external dual-needle watt/swr meter that I calibrated on my bench and found that it doesn't quite track with the SWR indication in the radio. Also checked this with my Bird meter and saw the same thing. I first realized this when I saw that the screwdriver tuner I'm using stopped at a solution that didn't look right on the external meters. That tuner gets SWR data from the radio and when looking at SWR on the radio display it is in fact tuning to a good low SWR. Makes me wonder if there's some kind of reactance in the radio between where it senses reflected power and the antenna connector. The difference can be like 1.5:1 vs 2.5:1. In any case, the radio otherwise seems happy with the tuning solutions. I'll have to take a look at the schematic for the 7100 some time soon.

I do still like the 7000 and will probably keep it and have been using it as another radio on my bench at home tied to a vertical at the back of the yard that has an AH-4 on it. My problem is figuring out how to add switching for some of the VHF/UHF antennas to the 7000 (it's a complicated setup).

So, yes, the 7100 is a pretty good radio. If there is anything I can say I don't like, it's the shape of the control head. While it fits the truck it would be better if it was a flat configuration so I could mount it along with the other radio control head. To set it on a desk they could have provided a plastic angled back to enable that.

Re: External PTT connection

Hello , I just thought I would add a simular question regarding PTT. If I  were add a different mic and preamp to pins 11 and 2 on the ACC Jack,  can I make a PTT for use through one of the modular jacks? Any info would be much appreciated:)

Re: IC7K locked up

Charles Scott <cscott@...>
 

Joe:

A long shot, but possible. There's been problems with the Logic Unit that causes a variety of problems. That's the metal-enclosed unit under the back-left of the top cover. I don't have specifics of what Icom thinks the problems are with it, but in my case after using the radio for quite some time it developed intermittent problems controlling various relays.

I pulled it and carefully cleaned the contacts. After doing this twice, the radio settled down when on my bench but still was questionable in my mobile. It's back on my bench now and working fine there and an IC-7100 is in the truck.

Icom service told me that the their solution was to replace the logic unit then (because all of the alignments settings are in the logic board) do a full alignment of the radio. That was more than the radio is worth, so I decided not to.

It's possible that you're having some issue as a result of problems with the Logic Unit or connections to the board below it. It's not hard to take the top off and remove then re-seat that unit to see if there's any change. (With power disconnected of course :)

Re: IC7K locked up

Make sure you're not in some menu item where the frequency knob does other things. For example, if you have the QS menu set up to the power output setting you won't be able to change frequencies since the big knob is used to adjust power while in that menu. So, be sure you don't have the rig in something like that.
