If you are into homebrew you just need four resistors and four press button switches....details are in the 7000 manual.

N1MM controlling IC-7000

Ronald Baran
 


Hello,

I'm trying to control the voice memories of the IC-7K through N1MM+.  The voice memories are located at MENU>S1>VO(F1)>T1-T2-T3-T4

Using the Date Format on page 142 of the manual here's what I've come up with so far (and BTW they don't work):

{CAT1HEXFEFE70E00601FD}   and my personal favorite {CAT1HEXFEFE70E01A0201FD} .

Anybody?

Don, you are sooooooo right!!! I totally forgot about the fuse "situation", not to mention as you said, if it ain't going into 50 ohms, all bets are off. I remember removing the Icom fuse holders and installing high quality heavy duty fuse holders. What a difference that made. And I always use a dummy load and measure with my N8LP LP-100A. No matter what my load is, I at least know that the RF wattage and VSWR I measured is accurate.

Oh yes I have played with fuses twice 
They caused my half power issue 

I tore apart fuse holder and cleaned ther solderd crimp conection  no issue after soldering  crimp.

Hi guys
 
check also your cable with fuse, often these fuses give some trouble to PA stage.
 
try with a short cable without fuses and on dummy load. Icom 7000 should run with 100 watt in 50 MHz.

Are you sure that:

1. Your RF OUTPUT POWER is not set at 50W RF OUT in the menu for 50MHz (rather than at 100W out), or that:

2. You are in AM mode, as that mode limits you to 40W RF out  maximum in AM.

Factory spec is 100W RF Output power from HF to 50MHz.

Otherwise it would seem that there may be trouble afoot. The IC-7000 is known for having RF driver failures, which almost all the time seems to be accompanied with an HF or VHF or UHF power amplifier transistor failure as well. I know from experience as my 7000 one day about 5 years ago, "died" unexpectedly, without any warning of any kind. Just wouldn't transmit on any band as the driver feeds all 3 PA transistors. Sure enough, the driver did die, and (wanting company, haha) took the UHF PA transistor along with it. Sent it in to SARTS in MI for repair and had both replaced at my expense of course. It's been fine since, so I keep my fingers crossed, but in the last 5 years its still been working fine. I've never run it as a base, only mobile, and overall, I've been very happy with it.

I've hopefully attached a photo of the spec copied from the latest IC-7000 brochure printed.

Re: IC7000 tx audio

Alan, AB6C
 

Typically, the mic that came with the "earlier" 7000's were made in Japan as was mine. The "later" ones were made in China. If you look on the back of the mic it will be prominently marked as to where it was made. Apparently the later Chinese made mic's did employ a different mic element, and therefore did not appear to need any transmit audio intervention, but did get a new PTT switch, both of which were definitely needed. I did encounter the PTT failure, and did replace the microswitch in my mic. An obvious poor quality part was used.

Because of all the negative posts, comments and reviews, of the 7000's transmited audio obviously prompted mods to "fix" this problem, such as Bob, AB5N's well known mod; along with a number of other folks "fixes" including change of mic element, baffleling the element or even changing the way it's mounted, etc. I assume all of these mods had some degree of improvement one way or another. I too was considering having Bob do mine too if not for that unexpected QSO that I posted about. For me, the TBW settings fixed everything for me. As is always (or should be) always said, YMMV.

YES you can used the PANASONIC WM61A but the newest is PRIMO EM 258 and is real to find in the UK. Here is t he adress : micbooster.com/primo-microphone-capsules/88-primo-em258n-6-mm-omni-electret-capsules-fc033.html

Write me if dont find the capsules and tell me about stady mods.

To me work with good audio report and full audio spectral frecvency.

Chose the PRIMO EM258 and beware to fake PANASONIC WM61 A or B because is obsolete the originals I find the original very hard and to reconised have two colors mark on the back of capsule aproach the pad solder : green and purple.

All the best from me to you YO2AA Ben – ROMANIA

IC7000 50 Mhz power output

Ing. Juan Carlos Parra
 

Hello everybody,

 

Perhaps it is an old question.

 

As user manual said, the nominal  output power in 1.8-50 Mhz should be between 2-100 W.

All is ok until 28 Mhz in my rig, but in 50 Mhz power only reach 50W.

It is a my rig failure, or a manual spec mistake ?

 

best regards

OK on your comments about the mic element replacement. I don't doubt that doing that will improve the audio further, but for "communications quality" the original one is fine by me.

Speaking of vinyl (and completely off topic), I have a copy of Felipe De La Rosa - Flamenco Fever (M & K) that I've had for years. Was shocked, but I shouldn't say surprised, when I saw what a good copy is going for these days. I knew it was an amazing recording when I got it (many years ago), but didn't think that it would become a legend as the Holy Grail of system performance tests.

Was rather a trip to listen to that on my Klipsch La Scala speakers. Some 40 years on from when I originally bought them, those speakers are currently on loan to a small performance venue nearby along with their partner, my Crown D-150A amp, and continue to get rave reviews. My Flamenco Fever copy hasn't been played in that many years and I would disrespect it to play it on my current turntable.

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...

FWIW --

My club has an IC-7000.  I once did some on-air monitoring of the transmitted signal, using my FT-817 with a 1" antenna.  I don't know if the mic is "Japanee" or "Chinese", but it is whatever came with the rig.

I was surprised that any attempt to lower the high-frequency edge of the TX passband (2.9 kHz, in WIDE, if I remember right), resulted in _awful_ audio.  Really distorted, independent of compression setting and mic gain.  I suspect there's something wrong with the DSP firmware.

Raising the low-frequency edge (100 Hz in WIDE) -- that worked fine!  Setting it to 300 Hz gets rid of much of the voice's low-frequency power, which is wasted on vowel sounds.  The voice becomes treble-heavy, but it's not distorted, and readability is improved.  It's not as good as an HC-4 element for contesting, but it's nothing to be ashamed of.

So I concur with the advice from Alan / AB6C:

. . . Use his suggested settings for TX bandwidth.

I prefer to do my own settings of COMP and MIC GAIN; but Alan's are probably a good start.

A while back, my wife and I had been making yearly cross-country trips from
the east coast (where I live now) to the west coast where we moved from.
I too wondered about my transmit audio on my 7000. Even listened in monitor
mode, but was never really convinced one way or another how it really sounded.
I usually operated mobile on 40 thru 10 meters. Let me tell a short story:

I called CQ one day, and was answered by a ham who ID'd, and said right off the
bat, that I was running an IC-7000. You can imagine my surprise with me not
having given him ANY info on what I was running. I asked him how he knew it was
a 7K. He said he could tell by my audio, which to my surprise had never been
mentioned before as being anything other than good.

He said he had 2 IC-7000's, and that I had my TBW settings wrong, and if I could
change them right now, he would guide me setting them. I said OK, since my XYL
was driving.

Going to the SSB Menu TBW settings, I set values as follows:

WIDE LOW 100 QS Menu Setting #3 M-3 TBW Hold for 1 Second
WIDE HIGH 2900 QS Menu Setting #4 M-3 TBW Hold for 1 Second
MID LOW 200 QS Menu Setting #5 M-3 TBW Hold for 1 Second
MID HIGH 2900 QS Menu Setting #6 M-3 TBW Hold for 1 Second
NARROW LOW 300 QS Menu Setting #7 M-3 TBW Hold for 1 Second
NARROW HIGH 2900 QS Menu Setting #8 M-3 TBW Hold for 1 Second
MIC GAIN 50% QS Menu Setting #2 M-3 TBW Hold for 1 Second
COMPRESSION ON M-3 COM Hold for 1 Second

Once I changed to these settings, he said "NOW it sounds like a 7K SHOULD
sound". Ever since I changed to these settings, I have been told the 7K's
transmitted SSB audio sounds great, fantastic. And this has been from dozen's of
contacts since changing my TBW settings. BTW, my mic has NOT been modified by
Bob, AB5N, and, as in a previous posting from Perry, K4PWO (above) mentioned:

"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."


By the way, my HM151 mike is the Japanese mic, and the only one I've ever used
with my IC-7000.

So this is my story for what it's worth. Hope this helps, it certainly did help me. And I
still love and use my IC-7000 mobile.

73's, Alan, AB6C
