Thank you Peter! Does not look too hard to do and it's always better to see these things in a video to avoid accidently damaging some ribbon cables etc. when taking a radio apart.

Don’t forget to turn off the band edge when you are done! Thank you, I followed these instructions and it worked perfectly.

Excellent video , good to see the shadow on the bench , confirming you were wearing an ESD wrist band. Thanks for the video.

Your Performance , Peter is like a top medical Doctor !! Outstanding Work !!

you are a beast!!! Thank you thousands bro you made my day...greetings from Italy

I always love it when you use the tweezers! I have got to get some of those!

Thank you for the peek inside.

Now here is a man who know's what he is talking aboot.

Hello Peter. It's great to see a video from you and a look inside the 705. Hope you and your family had nice holiday and have a nice Christmas. Thank you for sharing 73

Excellent Job, Peter💯👍🙋‍♂

Will be super useful now that some of the radios are coming to the end of their Icom warranties :)

Now if we could find a way to modify the Flex Radio SDR software for MARS and CAP frequencies as well as 60 meters……. Very well made video an very clean step by step instructions!

Excellent tutorial as usual!

great seeing you videos

Thank you soo much for the info and effort to make this video .. !

Just that easy in the hands of a master *Cheers* *73*

Great to see You - thumbs up before I have seen it complete ❤

I use this radio with the Xiegu amp (100w) and it is extremely versatile and I use the stock microphone and get excellent radio reports all the time. I sent mine in to have this modification made and it is certified by a ICOM technician so that I do not void the warranty. It cost about $125.

Hi Peter, thanks for your video. I can see IC-705 inside for the first time, nice costruction and easy to manage for any operation inside. Great job as always, best 73s my friend. Pasquale IW0HEX

Nice Radio, think the best what can buy on his world. In Conculsion with portability and multi usement

Hi Peter. Happy to see you again. Hope you have a great Christmas. 73s.

Hi Peter. Good to see you as always mate.

Good work, Peter. Thank you for sharing! Ich hoffe, es geht Dir gut. Gruß ringsum bei Dir und 73 de Olaf

Amazing to see how far RF electronics and electronics in general have come. This transceiver handles HF to UHF I assume.

Thanks so much Peter for posting this video on the 705 & for your easy & simple instructions especially as I was one of the luckier hams who received it early in 2021 & even at AUD$1800 I have zero regrets ever buying the radio & it's my favourite rig ever. Curious if one does this out of band mod does its internal filters show any appreciable drop out of the standard ham bands?. Thinking of doing the mod if I ever take the 705 on holidays with me into EU & can use 4m & 60m as my VK licence is CEPT compliant (VK has nil 4m nor 60m yet!). I have an earlier release 705 from mid 2021 & the front panel fascia says "D-Star" & it's been an awesome radio working with Sotabeams linked dipole plus 2m/70cm antennas off the Windcamp RC1 mount. Recently applied v1.31 firmware from Icom Japan site. Hope you've been really well & looking forward to more content!

das war ja einfach - diesmal, danke !

Nice clean job. I wonder if there are 90° hemostats/pliers with a thin cushion on the working end that would make it easier to reinstall the flex cables. Thanks for the video Peter.

Hi Peter, You made that look easy to do. Stay safe. 73 WJ3U

Now, if only I can get my IC-705 to pick up the HF bands and not only FM stations. I have tried four different antennas and still haven't heard anything on 40m, 20m, 17m, etc. Been trying to figure out this issue for months now. Ideas?

Very good video, thank you very much! Unfortunately some IC-705 has a blue glue on the middle screw on top and bottom to avoid opening. It is very hard to open it without destroying the screw. Vy 73 from DL2...

Easy to do once you get there! (but the journey there and back is really quite scary! 😐)

A word of caution. The RF connectors on the main board are VERY fragile. I found out the hard way.

What is the upper UHF RX edge frequency stop after this and do you achieve full RX spectrum VFO continues range from .03Mhz to something like 500Mhz / (200Mhz to 400Mhz unlocked ? - my guess is yes). It is a question as no one has mentioned anywhere what the unlocked band edges are ! I have one of the first 705 and will be leaving TX locked and asking the questions about RX out of curiosity and well aware performance will be poo as the band pass is only designed to go up to 470Mhz, unless some mods are performed to the filtering. Diode matrix array is old school from the Icom - IC2 era. Neat the 705 has a SMT32L051R8H6 and ill wait until the warranty runs out before I start probing at it, not that I really care as it is just a kick around radio unlike the 8600 or what ever comes first. The long anticipated SHF version or time for Icom to design a new portable receiver.

I don't have any need to perform this mod, but was simply interested in seeing what was involved in disassembling the IC-705. Upon re-assembly, do the front-panel ribbon cable connectors simply slide straight into the receptacles on the front panel, or are there any latches that need opening or closing? VERY impressive test bench, by the way! :) 73 form Tom WA1LBK

Could you tell me what temp did your soldering iron was at? As well, besides the soldering iron, what other tools were used to remove the diodes?

Excellent Video. If you do this MOD to transmit on GMRS 467.550/462.550 the output is only 1/10th of a watt. So no GMRS..

Ft710 next please 😎

Does tgis work on all 705 models??? Japanese, European and US models?

Unfortunately this mod doesn't work for transmit past ~454MHz. The TX indicator lights up, but the power output drops down to 0 watts long before 460MHz (and of course 470MHz). Maybe someone can figure out another mod so it does...

Sorry, maybe I missed something that has been explained, but why would anyone want full tx across (I assume) all bands? Perhaps for a maritime application? Does the extension also apply to VHF and UHF? It is a pity that the video does not show from where to where the expansion now ultimately runs and whether 10W is available over all bands. And how RX has been influenced.

This mod allows for TX on 450-470 but it doesn't turn on the PA. Have you looked into this? I have confirmed it is transmitting.

Does the full TX cover the CB 27 MHz band?

I noticed it was originally on 4metres, Are the European models being shipped as standard with tx/rx on 4metres?

Hello TRX lab,I have USA version 705 this mod is it UK model or can it work on USA version,,thanks,great video,good job, Peter,,great engineer guy,

Remove same ones for US version? Mine has the diodes in some different positions in the matrix. * it is the same two for US version also.

Would be nice to see the output on the spectrum analyser to see what effect this has on the filtering. Also is it just hf or is the uhf/vhf expanded as well?

Good day. How do I contact you? I have a question about this radio that maybe you can answer.

What about the receiving end? Do we need to remove any other diodes in order to receive the full frequency range?

How much power output are you getting on the 118-174MHz using AM? Thanks for the video, it is incredibly easy to follow.

As soon as you finish this modification you're gonna wanna get on 11 m and act a fool! 😂

At the end of the video, when you are testing the transmit, the VFO shows 5.360 MHz but your frequency counters show 10.190 MHz: what am I missing? Thanks and 73, George, KC1V

Is that mod for EU versions? TNX 73 DE NP3JD

Didnt you have to perform a full reset of the radio? I would have thought it would be necessary?

no need to de-solder .just use jewelers small flat head the diodes pop right off slide up under and just the slightest twist and there gone.I was done in like 10 minutes start to finish.

I came here and my desktop computer no speakers now !!! hey..leave a message ?? I just ended up with an ICOM 705 from Japan. Before I dumb it I can't be the only one ? Japan. Different amateur bands !!!! Nobody seems to know a mod but there has to be one !!!

cannot say that our new Radio is impressiv.. just an box of plastic.. get's and feeling of cheap china product hehe.. tnx for sharing 73 de LA4YUA

Just a word of warning:: If your radio gets wet, DO NOT put it in the microwave to dry it out. It will NOT work and you will destroy your radio!!! I think reprogramming a PLL chip in a CB radio is much easier than working on an ICOM 705. I've heard from other hams that an ICOM 705 and ICOM 746 are easily opened up and when they're opened up it opens up the VHF as well giving the ability to transmit out of ham bands. I would only do this as in an emergency situation. I plan to open up my Kenwood 281a. As far as I know, there isn't a way to open up the VHF on a Yaesu 991a. I've had the MARS mod done and HF is opened up. W Rusty Lane k9POW in eastern Tennessee

Whate about icom 905?

Super 👍🏻 leider hat Icom hier wirklich Scheiße gebaut muss ich sagen. Denn man kann ohne die Modifikation nicht im 60 m Band senden. Ich hab mein Gerät dazu eingeschickt und hab es machen lassen, weil ich es mir selbst nicht zugetraut habe. Aber ärgerlich, denn man bezahlt Geld für eine Erweiterung, die eigentlich nicht nötig sein sollte, um auf einem freien Amateuerfunk Band zu senden ..73

So it gains function by removing components... 🙄😂... what a world we live in where the manufacturer puts in EXTRA parts to reduce the performance of their product... 🤔

Is not a full band Tx… No tx power out on 70Mhz

yet another great video by Peter & Olaf (I guess) ... best 73s de DL6RDE / AA1KD, Charlie

Superb Video my Friend. Much Appreciated & 73 ⚡🙏⚡
