Re: [IC-7000] Any changes?

John ZS5J
 

There has been a small but noticeable improvement in the microphone. The new microphones have a
"Made in China" stamp on the back. The previous ones were made in Japan.

Although there has been a slight improvement in the mic, IMHO I would still send the microphone off
to Bob Nagy to do his mod on it. I sent both of my "made in Japan" mics to Bob, and it has made a
HUGE difference. I have one newer "made in China" microphone that I decided not to send to Bob, thinking
the improvements made by Icom would suffice. When I got the two back from Bob, and did some comparisons,
I kicked myself for not sending the new Made in China mic off also.

Bandwidth does still appear to be a problem, I only run in WIDE position - I think I have it set for 100 - 2900,
and it gets very good audio reports setup this way.

I think the IC-7000 is a great rig and I'm very happy with it. I'd run narrow transmit bandwidth if I could but it doesn't bother me that I can't. I've had two Yaesu FT-857Ds and the 7000 beats it by a mile. In fact, if I had to sell a radio, I'd sell my FT-950 and keep the little 7000.

The only change I am aware of is that all of 60 meters is now open as of serial number 0514455. This is of no use to those of us in Canada but that will hopefully change next year.

Thanks for the info on the TBW settings - I think they're used no
matter how you feed audio into the 7000, but if you run your audio in
via pin 11 on the ACC port, you bypass both the mic gain and
compressor circuits on the 7000, don't you?

Agreed, I did a lot of testing with several locals also with 7000s and

setting and control your bandwidth via an external mic or equalizer.
Narrowing the TX bandwidth creates ringing and hollow tube sounding
artifacts. Also keep the compressor and mic gain lower than recommended as
described in the manual helps. Over driving either or both magnifies the
DSP artifacts.
I found with my Heil mics that setting the compressor at 2 gave the punch
needed but without loss of intelligibility. At default/manual's setting the
intelligibility dropped but the bar graphs wiggled more.

Re: [IC-7000] Re: Audio setup

Mark Chalkley
 

I thought that had been fixed a long time ago, but I might be thinking
of something else.

I don't know how practical it would be, but what are the chances we
could do some sort of informal net at a pre-determined time, so anyone
on the list could join and hear what other member's radio/antenna
setups sound like, trade some advice on what sounds good, etc.?

90% of the rag-chewing I hear out there anyway is equipment-related,
so we'd just be doing the same thing everyone else is, but in a bit
more organized manner. With the mailing list, we might not have to
pre-determine the frequency, depending on band openings, but we could
just agree on a time, and settle the frequency issue a few minutes
before...

Re: [IC-7000] Re: Audio setup

I have a pair of old (but pretty good for the day) Koss closed-back
headphones, so I'll try those as you suggested.

I wonder where the AF Detector Output (ACC pin 12) is in the overall
circuit. I could feed that into my computer's sound card (or recorder)
and record it. As you said, that's probably not the same as recording
it after it's gone through the transmitter circuitry - who knows what
effect that would have...

I guess I could also press my Drake R8B into service using its line
out into my computer or a recorder, with a foot or so of wire for an
antenna and a dummy load or crank the power all the way down...

Re: [IC-7000] SWR scan function

de WB2CPN
I hope you had the LDG out of the line when you scaned.
You can adjust the length by comparing the SWR at both
ends of the band, High and Low. That will tell you which
way to go.

Hi Group,
The question may have been posed earlier, but my search did not reveal so.

I recently used the SWR scan function for adjusting the length of a mobile whip antenna. The readings came out fairly plausible, but quite different from a separate Daiwa SWR meter between the rig and the external LGD AT100 ProII tuner. The SWR scan in the IC-7000 showed high SWR (red part of the scan column) in the low end of 40 m SSB, while the separate SWR was quite happy most of the way.

I am perfectly aware that it could very well be the external meter that gave me some flawed readings, but my question is: Is the SWR scan function in the IC-7000 generally regarded as a reliable function, or is it a neat feature, but not really useful for exact meaures?

When I used to use it, the SWR scan function worked great for me, but I wasn't concerned with actual values, just what frequency the minimum SWR was at.

Does the dip show at the same point as your external meter?

Re: [IC-7000] Audio setup

Mark Chalkley
 

Jim & Phillip,

Thanks for the suggestions. I'm hoping I can just have one setup on
everything except the TBW, and let the Narrow TBW setting give me the
extra "punch" for DX'ing...

Since I'm running the audio into the Accessory port, I think that
bypasses both the gain and compressor sections of the radio, so I can
leave them set for the handheld mic, and use the ones on the outboard
pre-amp for the desk mic.

I've got another cable to build and an iBox coming in tomorrow, so I
should be ready to play this weekend...

It's tough listening to your own voice when you're in the same
room. Even using earphones. One thing you might try is to record
the monitor output as you test. Then, when you're done, listen
to the results and try pick out what you think is best.
My 7000 lives in the car and I have a 7600 in the house. I had the
advantage of recording the actual transmitted & received signal
to my computer through the sound card. But, I imagine that recording
directly from the 7K monitor output would be very close.
For the recording, when I made a parameter change, I would say what
I did over the air..
Something like; "This is TBW Low", "Now TBW Mid" "Now TBW High"..
"Now compression is 3", etc... That way if I liked or didn't like what
I heard on the recorded playback, I knew what setting caused it.
That allowed me to eventually determine what settings that I thought
sounded best.

Audio setup

Hi Mark,
I would do the basic set up with the monitor, then go on
air call a few times request some on air testing and I am sure some one will
help you out.

Try to get some one 100 - 200 Ks away and then look for a bit of Dx and see
what they think .. I have done it this way and I find a small tweak is
required for DX ..

All the best
