K5VK- I was all set to desolder, but discovered that all you need to do is take a screwdriver and pop the diodes off. Mine came off clean, works great!
Just had to do this, as someone who has owned "Chinese" cheapo radios in the past, I was surprised to see the narrow bands in this more modern high end radio!
Thanks for the video. I've avoided doing this myself for about a year because I don't wanna screw up an expensive radio! Your tutorial made it easy. WQWM407

Great video ! On the U.K. version there are more caps in the area, but I can confirm that it`s exactly the same (crossband repeater one is in the center between the 2 others !) so I`m a happy bunny, by by warenty ! I would strongly sugest letting a pro do it for you as you need a sharp scalpel blade as it`s so small it looks like a spec of dust, and if you miss you can interupt the tracers and byby radio !
So when scrolling cycling up/down frequencies using the knobs, it will display on the head unit from one end to the other? How about manual keypad frequency input?
Hi thanks for the video, I saw a similar video on a handheld where they just used a screwdriver to pop the diode off the board.... since the diode is so small is that also an option? I have limited electrical background but it seem like the end result would be the same, or is there a benefit to using a soldering iron ?
Great question! Using an iron, makes it clean removal without breaking the LANs or the components on the circuit board. Im a bit anal when it comes to my equipment. I would feel better telling my viewers the correct way to do it than risking damaging the radio if you slip. ;)
Being a new ham guy and just bought an ID-4100A, will this procedure on this model too? If not can you please do a video for the Icom ID-4100A as well? Thanks and 73!
What is the power output on the GMRS channels? I've read elsewhere that it is drastically reduced on other iCOM models when transmitting on the GMRS channels.
I can't speak to this particular radio, but when I tested on my ID-4100A I was getting over 40 watts on GMRS frequencies - very similar to what I was getting in the 70cm ham frequencies.
hey joey. before i attempt this, i gotta ask, do all features of the radio still work even after firmware upgrades? and once the diodes are removed, does the "off band" message pop up or are you able to transmit.
Anthony DiNardo yes, that message will disappear. (GMRS band) Be very careful, and take your time.no reason to rush. if you have a lighted magnifer, USE IT! lol Let me know how you make out.
Hey Joey I just bought the 5100A. if I remove these diodes I will be able to transmit on 137 to 174 and 400 to 470? I noticed I tried to transmit on my fire ops channel and I got off band message.
Anyone notice random screen taps when doing this mod? I will see my larger band selection flash as if I'm tapping it, and the FM button randomly flash too.
I've done this mod on Yaesu radios, and they require a factory reset afterwards. Does this radio need a reset, or reprogramming after this modification? Thank you.
ding ding! figured it out a cpl weeks ago and have been meaning to post here. Thank you! Now if we could only gind why the "aotu-off" feature does NOT work if any of the volume knobs are turned clockwise PAST the 6 o clock position. Radio will stay on all night
Kevin, I called ICOM for you. They would not tell me which ones by law. However, there are two diodes on the matrix that need to be removed. Remove the cover. If you're looking at the board, antenna would be top left and the radio face would be facing you. ( Large knob bottom right) Look at the right side of board. Screw is in the middle of the board. Move about and inch to the left of that screw and you will find two diodes over each other. Below them are empty spots. directly to the right should be a chip labeled NVC04. Hope this helps. Sorry for the delay! Same frequency expansion!
worked great thanks man!
New PINNED comment!! Awesome. I have two ID-5100A converted!!

I dont recommend that, because you could damage the board. But great job!

12.5khz.. typical for UHF

It is very easy to screw up the radio if not done carefully. WQSY810
i can attest, this totally works.
Thank you in 2023 for this helpful video ! ❤
Yes, I was the first one to create this video. You're welcome

@@Joeteck Awesome thank you!
@@r0bv123 whats your call?
@@Joeteck KJ7GDR. Just did the mod and can confirm it works!! Able to TX on some frequencies that couldn't do earlier.
@@r0bv123 KD2GAG here, glad youre in business. ** Now of course make sure your SWRs are not off the chart high because you added those frequencies.

Joe I love the video! I’ve got a question about removing the diodes. Could I shoot you an email?
Sure
Whats your email?
Lol, it's in the about section. I don't give it here.

hey. i just shot you an email. i think it is you.
sent you a pic. i got a little bit of residue that looks to be a copper bump. im wondering if im ok, or if i should attemp to scrape it off
Anthony DiNardo hang on, let me check
yup that's me. sent you an email back.. looks like the SMD part is still there. heat up the iron and try to get it stuck to the iron.
Same on 4100?
Hey Joey I just bought the 5100A. if I remove these diodes I will be able to transmit on 137 to 174 and 400 to 470? I noticed I tried to transmit on my fire ops channel and I got off band message.
ive did mods on tons of radios. and i always get **137-174.000MhZ --- 420-470Mhz
Does this keep the cross band repeater function active?
yes.. that does not change that feature.
Hey Any possibility to do same Mod in IC2730A.
Can you still connect to a repeater?
@marcelagarcia1866 yeah, unrelated to this upgrade. Can connect to all repeaters, including GMRS, with this mod.
Anyone notice random screen taps when doing this mod? I will see my larger band selection flash as if I'm tapping it, and the FM button randomly flash too.
No. It only modifies the frequency range. No firmware changes
@@Joeteck I figured it out. I still had the screen protector on and it was tapping the screen for me.
@@TheProSlasher lol, glad you got it worked out. I have two of these now. base and mobile.
@@Joeteck yup. Though, I learned last night that the th74a can't transmit on high power when plugged in to the wall. Whoops. :/
I've done this mod on Yaesu radios, and they require a factory reset afterwards. Does this radio need a reset, or reprogramming after this modification? Thank you.
Nonit does not. Just remove those bad boys and you're golden!!!! Enjoy!
@@Joeteck Thanks so much for getting back to me so quickly! 73
Of course! Your question was directed to me.. surprising low SWRs on GMRS!!
Is the other diode over the chip that says 473? You don't point out the 2nd one in your video.
Sure I do.. first 20 seconds shows you both. 0:06
@@Joeteck I'm sorry. I was looking at the time you were pointing at it with a screwdriver. Thank you for your reply and the video.
After this mod can you use the Itinerant Frequency? Say 151.5125
Yes.. that would be in band. Works fine.. just did it
Does it open for CB as well?
Mark Mollat no. The radio does not have the ability to TX on those frequencies.
anyone know how to do a icom 7100?
Do I have to reset the radio after modification? Do I loose all memories?
Export it to your SD card just on case. But it shouldn't.
@@Joeteck thanks.
Do you know hoy can I do it in my Id4100a?
Yup.... Here ya go: drive.google.com/file/d/1-5kurno3nmn1IytqedeyLbByB7scnPjL/view?usp=sharing
@@Joeteck thaks a lot! Gonna try and let you know. LU2ADS
Anyone know how to switch to the repeaters reverse frequency on this? I haven't been able to find ANY info on it.
ertonyrn I can check in about an hour. Going to stop driving soon
Thanks!
ertonyrn ok, I remember now. You cant. It's not like a Yaesu where you have a button. You have to program the reverse in as a separate channel.
If you press MONI while tuned to a frequency set up for duplex, it will switch to the reverse and turn off the squelch.
ding ding! figured it out a cpl weeks ago and have been meaning to post here. Thank you! Now if we could only gind why the "aotu-off" feature does NOT work if any of the volume knobs are turned clockwise PAST the 6 o clock position. Radio will stay on all night
Why are some sites stating to remove 3 diodes
ertonyrn could the European model? this is the 5100A not E
@@kismotbutod I truly have no Idea. The A version has cross-band repeat already enabled.
@@kismotbutod no, do not use that. You will remove other parts because it's not localized to that small area
Use a small pair of diagonal cutters in the middle of the diodes or to look pretty use a soldering iron.
how about a icon ID-4100a
