- To get the best audio out of your ICOM 7000 on FM is learning how to adjust your audio settings. Increase your FM audio level and never get a low audio report on any repeater or simplex.

Hi, you have helped me a lot as I was just ready to sell mine as new ICOM IC 7000. I adjusted the filter and everything went like never before. Now I keep the transceiver. Great advice.
Very useful information. Thanks for your video.
Thank you for this video. 👍 73
Absolutely my pleasure.
Wow!
I just had a nice conversation with you regarding this topic !!
I appreciate your input on my tbw adjustment.

Now I'll watch the video 😎
lol, awesome. Glad to help and hope you enjoy the videos. 73
Yes, There are hidden menus where you can adjust the S-Meter, but before you go doing that double check and make sure it isn't RF. One of my IC-7K's was mobile in a Toyota Prius. In the Prius there are High Voltage lines which produces massive RFI and EMI issues causing my S-meter to do the same as yours is doing. That's why you should check to see if something producing noise on that band.
@Standa Šejn - Your very welcome! Glad it's helped you. 73! :)
@madflyer1093 - That's great and I'm glad. Makes me wanna cover the IC-7K more. Remember to experiment with comp/off and mic gain up. As long as you have full output is the key! 7!
Thanks again and there's more to come. 73!
@Conor Turton - You will find an end result of 3 - 3 1/2KHz of deviation performing this adjustment and will hear a clear increase in audio level. Normally you'll experience only 2 KHz of deviation without performing this adjustment which is where most of the low audio reports come from with all 7000's. it's an improvement and helps till switch out microphones ,or get a mic mod done. I find on all my 7000's with my Heil Traveler headset audio is perfect.
Please advise how to display my filter. Thank you
On FM the FIL2 & FIL3 settings limit FM deviation to 2.5KHZ as required for NBFM. This is on page 76 of the manual. FIL1 limits deviation to a little less than 5 KHZ for standard FM. This has nothing to do with the low and hi audio frequency cutoffs used for SSB, although a 2.5KHz deviated signal will sound very weak and tinny on a standard FM radio. Many US hams don't know what narrow-band FM (NBFM) is, although it is now the standard for commercial radios in the US and is common in Europe for hams.
Overdriving mic gain will not result in overdeviation, although the audio can sound distorted sometimes. And a repeater will not cut off the signal as a result, based upon all of the repeaters I have adjusted. It has the same type deviation control that the 7K has. -- Steve, W3AHL
Hello Steve. Technacally that would be correct except the transceiver does transmit anywhere near 5KHz of deviation let alone 3Khz so the rule of thumb does not apply. That was a little minor issue with this rig. It normally shows only about 2 - 2 1/2KHz of deviation. On any given day and all repeaters adjusting these filters absolutely showed an increase in audio.
One other thing Steve. I'm no repeater guru, but what I also know is I've encountered on a couple occasions being told I was cutting on repeaters because audio was too high. Adjusted the audio and fixed the problem.
did u repaint your VFO in the other video.its all scratched up in this video. u must really use this radio. love my 7000. thanks again for these videos. have sent them to many people. very helpful. 73.
Greetings, I have an Icom IC-7000 S#01 which is the version for what I believe is Japan. The frequency range is from 30khz to 145.99Mhz and 430Mhz to 439.99Mhz. This leave a tremendous amount of the 2 meter and 70 meter band out of the range of the radio. It just so happens that the upper parts of band are where the repeaters are. Is there anything I can do to open the frequencies for the IC-7000 version 1? There are no MARS mods anywhere for version 1. There is actually very little information on the version 1 on the World Wide Web. Any help will be greatly appreciated.
I am not aware of any such mod, but I also have never modded to alter any transceiver from its original fcc restrictions.
@@N2RRAny This one is not configured for North American frequencies. That is the issue I have. It is rather crippled for icom region 5. I believe it is in income region 1 right now. It is unfortunate.
It is my pleasure to inform that I found a receive modification that opens the range from 0 to 199.99Mhz and 400Mhz to 470Mhz. The transmit is still crippled. But the study is still continuing. There are some ideas that I will be trying after I find my soldering station. The beauty about diode matrix configuration is that they can be soldered and resoldered over and over. It is an easy process. But study still has to be made. A diode in the wrong spot may not be beneficial.

Hi there, what setting would you recommend for UK Repeaters, they tend to be Narrow FM now, the channel spacing on ours is 12.5khz on 2mts, used to be 25khz, but they seem to be fairly sensitive to over deviation now, think their 2.5khz now and were 5 kHz, but I am not certain on that....Fred g4vvq Nr London UK.
good tip sir
Hello Eric, thanks for your videos. I read below here that you own a Prius.
I also own a Prius, a MY2012 model, the last one that Toyota made. I watch your videos because i recently bought a used ic-7000 for a mobile installation. Could you tell me more about possible disturb coming from the car ? I hope that the rig remain usable, now i am bit worry about it. And again, where did you put the front panel in the Prius ? Could be a suggestion for me. Thanks in advance, ciao, Graziano IW2NOY
Bonojourno Graziano! My Prius was a 2006 which I was able to install in the little compartment center of the console. With a piece of wood sized for the face plate for the head of the radio fit perfectly. Like it was designed for it. Wish I could take credit for the hybrid mobile EFI/RFI issue you can thank K0BG.com. I did following some grounding and shielding issues and worked for me. Was it worth the trouble? For me it was. Do not despair! The IC-7K is a great radio and using the filters properly dealing with all interference issues is unmatched to any other radio. Happy DX'ing!
Do you have a video of your Prius setup? I'd like to see how you installed it. Thanks! 73
First, thanks for watching my vids.
Second, I really don't have any in detail, but I'll try my best to explain how I went about it. Maybe I'll try to create a virtual detailed schematic and upload to CZcams for Prius owners.
On the center front panel is that little compartment with the flip door below the am/fm radio. I took a piece of wood the right dimension's so the face plate for the IC7K could be screwed into it flush and evenly on all sides. Being the cable for the detachable face runs side ways it was easy to then slide it all together into that compartment. Like an old school Benzi Box radio. I then tucked the interface cable under the center counsel and ran under the drivers seat where the main unit sat. The coaxial cables ran from the hatchback through the interior panels and along side the passenger seat under the floor kick panels and out the center panel dividing the driver side door from the passenger door. Continuation on next line.....
+N2RRAny - No cables are visible this way and do not interfere with passengers. Just a little loop from the hatch into the interior in the back. Some grounding and bonding was done to eliminate some EMI/RFI into radio starting with bonding the hatch and mounts to the trunk with flat ground straps. This was done by placing the ground straps under the mounts so the screws would go through then bite into the hatch. This insures grounding from the mounts to the body of vehicle. This was done on both sides. Worked out great. I then took a 1 1/2" flat ground strap and bonded at the exhaust pipes between the catalytic converter. I made sure I added flat ground straps as wide as I can get to fit each location that used sensors. Many of the sensors in Prius are transmitting a signal to the computer. There's a little customizing when it comes to preventing EMI and RFI issues, but worth every bit of effort. I hear these issues were corrected with newer Prius's are more radio friendly.
+N2RRAny - Just can't confirm those claims, but hope this gives you some idea what was done. My Prius was a 2005 and as you can see those who said it could t be done didn't put work in to make it happen. My noise floors and very little and comparable to what you'll find from operating at home. Hope this helps.
Hi there if i key up on FM with my 7000, the alc meter goes right up into the red, is that normal, swr seems ok, not effected by mic gain...Fred in england g4vvq.
Been a few years since you got an answer, huh? :) Yeah, on 2m/70cm, the ALC pegging out is normal on FM.
@@aut0mat0r Hi there, its been so long I don't even remember putting this on here, I still have the 7000 but its on loan about 60 miles away, I also have a 7100 and a 7300 now...cheers from Fred in England g4vvq
on VHF, my s meter is always at s8 or s9 and a fellow ham said that it should not be that high. i notice that yours is not always at s8 or s9 either. is there a setting i need adjust for this? mine never drops to s3 or anything like that on VHF.
Sorry for the late response. Coukd possibly be something in your area that's causing this problem. In that case may have to sniff out the RF leak which could be from a plasma TV or something.
N2RRAny interesting, i was thinking the S meter need adjusted down in the factory settings somehow. s meter is normal on UHF, but S8 or 9 always on VHF. maybe there is "noise" in my area. hhhmmmm. thanks for the reply and feedback. N5XTC
Have you tested this with a FM deviation meter?
You say you are going to show how to install repeaters in a 7000. You don't so do it
...twice.

Somebody didn't read the title...
