So glad I found this video! After I already removed 420 and 423 I saw no changes in band plan or in language (and I don’t even know how to do a factory reset 🤷🏻♀️) but your menu walk-thru just gave me everything I was looking for. Thank you so much!❤
Thanks Mr Jones. I noticed that I had 2 extra diodes in the middle top row and decided not to remove 422 until I learned if it will work ok and not brick the radio. others have made comments that no matter what I do it would not TX on 11 meters. I will remove 422 then do factory reset and setup the band edges for 11 meters. mine is the 100 watt version. I wonder what would I be missing if I left those 2 up top middle in place?.... I can rx from 0.030.000 to 74.80 already. also I see 60 meters will open up further if I remove 405...it's the 2nd diode up from the bottom in the 2nd row. thank u for your video. this gives me renewed hope for a project when I get off work. can I break the 422 diode loose with fingernail as I have read a couple people say it works.
It will definitely tx if you remove....the other 2 in the top middle 1 is for English menu as default..the other is for US band plan as default...if you don't want to change band plan then choose anything other than ( user tx)...use default or off and you'll have full tx from 100kh to 74.8mhz.......or make your own when using the user tx..in (USER TX
@@mrjones6770 you were exactly right. I just removed the 422 only and it works like a charm. no reset , just take out 422 and power it up All is Good !! Others said it could not be done on a Japan version... Well they did not know what they were talking about. Thanks again Mr. Jones
i've seen on ebay that japanese voltage is 100V.. not the same as US or Europe. Did you have to use a step down transformer with this IC-7300 because it's from japan?
Just buy the USA one and get the warranty. Stop being cheap. If your radio fails, the money you saved will immediately go back into a repair. Most likely for HF usage some of the band coverages are omitted.

I removed the diodes and did a factory reset and my radio works just fine. Thank You for your help!!

Glad you found it useful .. this is why I made the video, because nothing online about the Japan version.
Thanks! I just ordered one from ebay last week.

@@jasonriggan3715 your welcome 👍🏻
Easy mod, worked great. Thanks! (now to figure out the same mod for the 7610...)
very nice infomation regarding this rig a japanese version already tested and effective to my ic-7300 thank you so much & 73'...de du9nz june.
what meter are you using on top of your radio ?
You didn't mentioned 4 meters!! Does it cover? And if so what's the band limits. De 4x1uf
What about the ic 756pro Japan version

Not true...13.8 volt is what it is
That would be the case if the 7300 had a built in power supply which it does not.
Does it maintain the 100 watt tx in 11 meters after the mod?
Yes it does
so how does finding the firmware go and how does that flash?
Are the japan models 100 watts ?
Yes...but there is 50 watts as well.....ic7300 100watts.....ic7300s 50 watts

Hi, do you know how I can do the Mars Mod on a Japanese version ic-705?
sorry not sure...it can be done, but i have never done it...should be similar though
is there anyway you can show how to do this
All warrantys are void anyways when u do the mars mod so really doesnt matter
True... it's a risk we all take.
But they are a bad ass radio
mine didn't loose warranty.
Thank you. I am in the uk i bet it the same
The open transmit one will be...with the radio upside down and screen face you as you look down at it..very top Left-hand corner
Do you know of info to change a Japanese 7610 to US language and band plan? Or US language and mars?
Just buy the USA one and get the warranty. Stop being cheap. If your radio fails, the money you saved will immediately go back into a repair. Most likely for HF usage some of the band coverages are omitted.
So make sure get a 7300
I have the same radio
