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

Mark:

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.

Doboli any idea if the Panasonic WM61A is similar to the WM61B, I cant find the B in the UK but plenty of the A, might have a go at modifying my HM-151 on my newly aquired IC-7000

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.

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.

I was an avid SWL’er long before I became a ham.  I had numerous receivers: Drake R8B, Lowe HF-150, Sony 2010, JRC NRD-535, I’ve lost track.  But the easiest one to listen to, for me at least, by far, was a Hammarlund SP-600 “boat anchor”.  I won’t call you crazy - I can relate...

Thankyou for your reply Mark.  I did read about the HM115 mod that Bob does so if I do get one I will bear him on mind. I do use home brewed headsets for mobile use whatever rig I use so it will be interesting to experiment. I just wondered if Icom had done anything to improve the audio on the newer IC7000s....I know a lot of the problems are caused by poor operating techniques. This is especially noticeable on FM transmissions on VHF / UHF.

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...

Mark:

The dirty little secret, at least as far as I can tell, is that this model microphone never needed the mic element replaced. I've had several of them and in all cases the TX audio problem was due to misalignment of the mic element with the pin-hole in the mic case. I fixed that on mine and all sounded great.
