I am a little confused about what you said regarding re-installing the channels. It the programming is already on the SD card, why can't one just "Write to radio" (or whatever it says) from the existing SD card files? (SD card to radio)
You should be able to if you have already backed up. I mentioned that to make sure you backup memory before you do the mod and then reset. After that, it is too late. You have to reprogram it all as if the radio was new. Best wishes.
the highest and lowest end of the transmission range which is after the mod. in ftm-200de is it known if it will work? I ask because I have the ftm 200de and it does tx only on 144 and 146 and on 430 and 440
My buddy is a deputy and i like to listen to them when he is on duty, the 200D doesnt have those frequencies, will this mod open the 155 to 156 frequencies?
You are welcome. It is a great radio for the truck. I really like the simplicity and functions. However, I'd go with the FTM-300 or FTM-400 for a base station. I have the FTM-400 on my base station.
@@josedisco My understanding is that the Japanese versions are locked down in software and cannot be "opened up" for extended frequencies at all. Just the US and European version are capable. I only have first hand experience with the US models in any case.
I just bought the same unit FTM 200D , I have similar problem , the radio come up with TX PROHIBITED for most frequencies VHF and UHF, will this mod work and open up both UHF AND VHF FREQUENCY RANGE ?
It will open both VHF and UHF assuming you have the US version. If you have the Japanese version, it will not work. Note, you will void warranty and just because you can transmit outside HAM bands, doesn't mean you should or that the radio will have output optimized on those frequencies. I did mine mainly to have access to GRMS (UHF) frequencies in case of emergency.
You are welcome. After removing the resistor, put the cover back on and power it up. It will reset and behave like a new radio and you enter your callsign. If you are going to reprogram it manually, no problems. If you are going to restore with the SD card, make sure to watch end part of the video before any modification.
Hi. I cannot speak on the FTM-200DE with certainty as I only performed this on the FTM-200D. Just purely speculation on my part, but I don't see why not. Let me know what you find out. It may be helpful to others.
@@donsdoityourself2547 hello i bought the ftm-300de because of the more equipment and i had the mod made by the dealer what i saw in the funk he only removed the resistor as you did in the video i think with the ftm-200de it will be the same
This radio ftm 200 came from japan. Is there any different software or hardware? The resistor has been removed. Can you research and help me? Thank you.
I did some research and it appears the Japanese models will not work this way. Was the hardware the same? See old post I copied from a Facebook user group: *******" You can do the MARS mod as described but it will not open the frequencies to match the US band plan nor up the power output. About the only thing I would use the JA models for is a Wires-X donor radio if I wasn't concerned about the max power output and don't mind only using 1/3 of the band plan we have.
Wes, it is a RAM mount. The type I am using is called an X-grip that people would typically use for a smart phone. So you need that and the suction cup extension to secure to the windshield.
Give me a few days and I'll check it for you. I did make sure the Antenna SWR was acceptable, but did not transmit at full power. Have to get my dummy load and etc.. out to my truck.
Okay... UHF Power in general appears to be lower than VHF. Seems I get 49W on VHF (HAM Band), 28W on UHF (Ham band). GRMS frequencies are 24W. These are all into a 50ohm dummy load. Now I am wondering if the UHF on my FTM-200 has an issue? Should be 50W? My FTM-400 is 50W accross the board... Very flat.
@@donsdoityourself2547 Thanks for info. It’s is interesting because I found a group on Facebook for the ftm200, 300. Two people there state they are getting 50 on gmrs.
OK... figured it out. I have a cheap portable power meter I use for checking things in my vehicles which should be good up to 500MHZ. It turns out that it is not accurate on UHF. It rolls off. I put it in series with my inline Diamond SX400 with my FTM-400 in my house, and it reads about the same as the FTM-200 in the truck when the Diamond SX400 meter is reading 50W. I think it is just a poor meter. Given that, I'd say it is 50W or real close across the bands including GRMS. I don't want to pull apart my Base Station to take the Diamond SX400 out to my truck, but given the comparison between the meters inside, it makes sense now. Edit... I calibrated/adjusted the meter against my Diamond SX-400 and FTM-400 and now I measure the 50W across the VHF/UHF/GRMS bands on the FTM-200.
DO NOT USE A SOLDERING IRON! A strong needle will easily pop that thing out without melting things. Way to small work for any iron. A sewing hem needle with a little ball on the end . A big one 2 to 3 inches.
It is small for sure, but if you have a very fine tipped soldering iron that is tinned well with just a little bit of solder on the tip, all it takes is a brief touch to heat the part and it pops off with a little push. I am afraid to pry it off and potentially break the circuit traces. In any case, if that works for you, great. There is enough space around this particular resistor to do the job without heating other parts.

What was the output wattage on high power on 70cm on amateur bands and GMRS? My radio is outputting 45 watts on amateur and only 20 watts on GMRS.

C'est bon ça fonctionne je l'ai fait il y a 2 ans et toujours opérationnel 👌73
My buddy is a deputy and i like to listen to them when he is on duty, the 200D doesnt have those frequencies, will this mod open the 155 to 156 frequencies?
I haven't looked.. but I believe so. In any case.. never transmit there.
Great video. I'd love to have one of these radios, they look so cool. Thanks for posting this!

@@donsdoityourself2547 Someday! Right now a base station is a *little* too expensive for me, so I stick to HTs but it's still a lot of fun!
Thanks for the video. Do you know how to unlock the Japanese version of the FTM500D?
@@josedisco My understanding is that the Japanese versions are locked down in software and cannot be "opened up" for extended frequencies at all. Just the US and European version are capable. I only have first hand experience with the US models in any case.

Does it allow marine freq transmission with mod?
I believe so, although I did not test that. I was more interested in the GMRS on UHF.
Do you have the "brain" mounted under the seat? Is the built-in speaker sufficient or should an external speaker be used?
Yes, I mounted the main unit under the driver seat and I am using an external speaker with the auxiliary audio output. Thanks for watching.
After removing the resistance of the radio, what other procedure must be done? Thank you very much for sharing the information I have the same radio.
You are welcome.

Gracias por el aporte me fue muy útil. Gracias mil... Saludos desde Argentina...
You are welcome. So happy this was useful for you.
What is the upper TX limit on UHF after the mods, please?
I know it goes as far as the top of the GRMS channels (467 MHZ). Never tested it past that.
nice job does this also work with the ftm-200de or only with the ftm-200d has someone experienced it or you

Gmrs frekanslar da tx yok
144-146 ve 440-440 var

What is the new TX range? Will it go down to 136 or 137 MHz?
The low end of the transmit range is 137Mhz after the mod.
All good!
What is the range of TX on 2m and 70cm after mod?
Use your imagination!
@@cnguyen32 Ha, ha.... 🙂
Will this unlock 1.25 meter tx?
No, it will not do that. It opens up the 2M and 70CM to some adjacent frequencies .
Is the 200dr the same
Yes.
Ftm 200d ben de direnci kaldırdım ama gmrs olmadı
Not sure why it wouldn't. Does your radio have different firmware? Works on my FTM-200 perfectly, but it is a US model.
