Yaesu G-450C rotator doing a full rotation and return showing the overlap feature.
Removing the limiter from a Yaesu ft7900r to enable the capability to transmit on gmrs frequencies and other bands not originally intended. Very small resist…

@703511 I believe that is incorrect! I’ve paid my $80 to the FCC and have
my GMRS license. As long as I stay within legal output (watts) I can use
any kind of transceiver I want.
@warezjoe5 *WRONG* Amateur radio’s are not what is known as “Type Accepted”
for operation outside the amateur bands. Although they will in fact work
just fine in the GMRS band, it is in fact a violation of Part 97. I was
trying not to begin quoting Part 97 rules but I guess it’s too late for
that. Just ask any licensed amateur operator, or better yet, look it up on
the official FCC website, or ask in any amateur radio forum.
You do realize it’s illegal to transmit on GMRS using an amateur radio.
Dummy load or not, what you did in this documented video is not kosher. If
you intend to do this, and a lot of hams do, you shouldn’t video-record
yourself doing it for all to see.
Yes AND no. You “CAN” use any radio you want, assuming you stay within the
legal limit, and you’ll most likely never have any problems. But there are
still “type accepted” radios you are supposed to use. So if for whatever
reason an FCC jackboot is examining your GMRS station and your using a
“non-approved” radio, you can still get in trouble.
I should note that I do occasional stuff for a taxi company and also have
light business licence for 449mhz hence my need of enhanced coverage. Wish
it could do cb too but I have never come across any radio that goes down to
27mhz.
why?
any info on how to do it on the TH-F6 Kenwood?
Can transmit in PMR 446?
ive done this mod and mine now does 136-174 tx and 420-470 tx is this the
same as yours as you said 120-170 and 420-470 at the start of this video .
I did both my ft-7900r’s .. Works good.
I found it was just as easy to use a small pedicure kit scissor tool and
snip the jumped in the middle. The jumper still looks like it is there, but
it does not do anything, and bands are wide open.
I did it on my ft7900e uk version. I just snipped at the jumper with some
nail scissors and then used a safety pin to “ping” the remaining bit off.
Works great many thanks.
I did mine by just ripping the part off with tweezers. Not fancy or neat,
but it works just fine. I’ve modded EVERY radio I’ve owned including HF
radios. I laugh at people who worry about what is against the rules. WHO
CARES?! I use my radios on GMRS, FRS, marine VHF, MURS, ect. Sure it’s
illegal. I do it almost every day and I am a licensed ham, general class
too. No giant foot from the FCC will come down from the sky and squish you.
Just be courteous to others on the air and have fun.
According to Part 97, GMRS radios must be “certified” to be allowed to
transmit on GMRS frequencies. One big factor of getting certification is
that the radio CANNOT transmit on Amateur frequencies as well. While having
a GMRS license and staying below the 50w maximum will keep you under the
radar enough that you likely will never get caught, it is still breaking
the “letter” of the law. There is also provision in FCC rules that you can
use any frequency at your disposal in an emergency.
@703511 That is correct info, but what is the point of being an asshole
about it? He isn’t hurting anything and there is no victim here. You
corrected his mistake, now it’s time to move on…
wats the other jumper for as ive dun the first one it works but ive tried
going on pmr channels and thweres a few missing inbetween some of the
frequencies
Hey I just picked up a 7900r. It works great sept The factory setting on
the mic is to low. It has great signal. nice and clear everyone says. but
verry low volume.I have the mic gain set on wide And there are no other
settings to raise the mic gain. Do you have any information on how to fix
this? Thanks
Thanks for the video. I’m not great at soldering. What temp and tip did you
use to get that cap out?
exactly! there should be a radio out there that would cover all these frs,
gmrs, and ham frequencies and all you would have to do is get the license.
just like the HAM radios, people buy them without a license. The purpose I
think, is to be able to comunicate with less equipment but, I think that
these laws make you spend more money to jump through the hoops and call
yourself “legal”. Why carry two radios if you can do it with just one?
license? just pay it! do not make me carry/buy two radios
Great video! How’s the sensitivity when you monitoring the frs / gmrs
frequency ( 462 to 467 range )? Thx
@warezjoe5 TECHNICALLY: the FCC can still be dicks about “approved radio
types” and such, but as long as you stay within legal output power it
shouldn’t be a problem unless some nosey asshole sees this video and
reports it, or some FCC jackoff with too much time on his hands sees the
video himself and decides he wants to investigate further. Fuck ’em anyways
I say, thanks for the vid!
I’ve heard tx ends at 470mhz after this mars mod. Can you confirm this? If
not what is the upper frequency limit which the transmitter will lock?
Great Video, Thanks for sharing…
You believe wrong — but then again, I believe you knew that all along. The
rules about using only type approved radios to transmit in any of the Part
95 services are totally clear — you are welcome to say that you don’t like
the rules, but don’t bother pretending that you don’t know that
transmitting on GMRS with this radio is illegal in the US.
You said tx up to 480mhz? Would like to confirm this as I see one comment
below says he got to just 470mhz.
Can anyone confirm tx to 480mhz?
