I've had more than one ham tell me that I sound like a "chipmunk" when we are all tuned to the same displayed frequency. When I tune .08 kHz low (i.e. 50.124.92) they all say I sound OK. Most have met me personally and know my voice.

I assume there's a TCXO in the box. Do they fail? Is there a "trim" control for it? The unit temperature was in the blue when I tested this last.

Thanks in advance

yep, I checked the specks and I get 50 watts on 2m and 35 on 440. 
Plus with all your guys help, i am back in working order.  2m now works!!  Somehow I got the offset wrong awhile back. It was 500 instead of 600 offset. I figured a Reset of the radio would have made it default properly. Guess not.  To bad I overlooked it. Now I have to re-program all the dang memories.
Thanks alot for all the help

Indeed, some repeaters do transmit a tone (there could be several reasons for that). Noone said they don't. After all, there is supposed to be only one transmitter on the output frequency of a coordinated repeater, that repeater itself (unless someone by mistake transmits simplex on the output frequency of a repeater). Therefore, you do not need to set the squelch to that tone to hear and use that repeater and you do not even need to know what that tone is. If you set the mode to FM-TSQL but you do not set the correct tone that is transmitted by the repeater, then you won't hear anything even though the display will show a received signal strength since audio will be muted.

Nice call sign Rob. My 7K puts 50 on 2 meters 35 on 440.

I have run my 7000 off a full size deep cycle battery.

I doubt you'll get 10 hours.

Rx current listed as 1.2 ~1.8A 1.5 Maybe 1.5 avg.

Tx listed as 22A max but I have never measured it that high. Mine runs fine on a a RS-20 and I don't ever see the meter at 20 A. In factI thinkI measured CW full output draw at about 18A.

If you factor in Tx then whatis the average current? Depends on Tx time, maybe 3A? 18/3=6

But then you have to add in the inefficeincy of the booster As the battery voltage drops, the booster is going to draw more current to keep the same Vout. Power= Voltage x Current.

My guess is closer to 5 hours if that.

And that's assuming that an ionizable atmosphere
even exists on the planet of Mars!

Interestingly I just read that only the lower bands mostly 160m, 80m, 40m and
30m (if there were FCC jurisdiction there) would be useable on planet Mars
because of the effect the lower ionospheric electron density has on the MUF
(daytime MUF is 10Mhz on Mars versus 40Mhz on earth during maximum solar
ionization and seasonal conditions, during nighttime it falls to 2.4Mhz
on Mars). Whereas the intrinsic critical frequency on earth tends to be
14Mhz at the F2 layer, on Mars it would be closer to 3Mhz.

We learn something new every day even if it's from a joke !.

Thank you for the info -- I haven't checked current draw between 25% and 50% yet; definitely going to do that the next time I am in front of the radio.

Do you use one of those 'battery boosters'? I have been doing a lot of reading about them and it seems that the camps are divided between "must have or your radio won't work" and "completely unnecessary".

Optima makes a nice 38AH marine-grade battery that I am now considering. Though I have to admit that I still love the rectangular case from powerportstore that houses a smaller battery and the radio. I am a sucker for a nice case. ;-)

hi i think my uhf finals have gone,
i am only getting 13watts out on 430mhz and 8watts on 440mhz
the thing is i have not used the radio on 70cms for some time
hf and vhf all work fine,the good thing is i have 2months left on the warranty,
will icom try and get out of the repair seeing it is the final
have icome admitted to this problam with the ic-7000

thanks dave browne 2e0dmb

It's time for the maintenance crew of
that repeater to do an alignment!

I have just the opposite issue. I can bring up all the 2 meter repeaters I can hear, but I have a problem with our 440 machine in Roswell, Ga. I have the correct tone selected and tone mode.

Here are some interesting data points:

- the problem is only with one repeater

- frequency counter shows the xmit freq is slightly low. .4737 vs. .4750. This is consistent on all repeaters

- local repeaters further away (20 miles) come up just fine.

- if I use "split" operation, and make the xmit frequency exactly .4750, it works 4.0.

- if the temperature is above 65 degrees, the problem goes away.

So my conclusion is that in the winter, I have to operate in "split" mode on the local 440 machine. In the summer (above 65 degrees) I can operate the 7K in normal repeater offset mode. I believe the issue is with the machine and not my 7K.

Your situation may vary, but the above are some things you can try to troubleshoot the issue.

Simply listen to your IC-7000's signal on a
separate 2m receiver. You should be able
to hear virtually ANY so-called "sub-audible"
tone if your IC-7000 is transmitting it.

These tones were only "sub-audible" back in
the days of the old commercial FM transceivers.
Back then, the receiver audio was definitely
limited below 300 Hz by filtering. Current
ham rigs are basically wide open at the low
frequency end of receive audio response, so
the tones now come through to the speaker.

Some of the previous posts are incorrect. Some repeaters do transmit
a tone as well as receiving one for tx. This may or not be the
problem. Good luck.

Brandon Bailey

2 things, first you say you saw 80-100 watts out on high power. Unless something else is seriously wrong you should only get 35 watts or so out on 2M high power.
2nd if you are getting power out, take another radio and set it to tone decode or TSQL the set your 7000 for the tame freq and pl with no offset / simplex. Can you hear yourself? If not then there is a pl problem. If so then recheck your settings for the repeater.
One other thing it could be is low tx pl and that would take at least a call to icom and probebly a service monitor to correct.

Hope it helps

Richard,
Have you checked your current draw at 25% power level?
When I built my "travel" go pack using a 18AH battery I found that the draw differential on my IC-7K between 25% and 50% power was minimal.
Switched to a new 25AH battery, same size and weight as the original 18AH, much better for "digital" operations.

I appreciate the info on battery life... I was thinking that for purely portable operation, 18AH would be fine (caveated with the battery booster) -- I could likely receive for almost 10 hours and xmit an hour or so. That'd make for a fine day of operation on a local mountain. For more serious portable operation, a larger marine-grade 60AH battery or similar would certainly be a better option.

I run my IC-7000 at 25% power by default and only increase if I have trouble making the contact.

trouble bringing up 2 m repeaters.

Hello,
I am having trouble with my 7000 on 2m. I have the correct tons and offset programmed. I can not bring up 2m repeaters. It seems as though the tone squelch has quit working on 2m. It works fine on 70 cm repeaters. i reset the entire radio. I hear it working on simplex by listening on a hand held. It receives just fine. It transmits on simplex fine. Power output is 5 to max. I think it was 80 or 100 watts.
I checked the 2m antenna swr also low and high power. My hand held keys ups the repeater on 1 watt. I have run out of troubleshooting ideas. Anyone else have this problem and and fix.
Thanks,
vern

Also take in mind that you can set different frequencies for FM-TSQL and for FM-TONE, make sure you are setting the right one. If there's any question you can set them all the same.
