Obviously I’d not want to stick a hot iron inside it though I’d leave that to you as you seem more competent than me at that sort of thing.. Fab channel mate hope to maybe catch up with you sometime soon and purchase another moonraker off you for my collection..
Thanks Phil, Yeah It seems to be a very popular radio especially while Yaesu are offering seemingly endless cash back offers. I am tempted to buy one myself in the near future to have a proper play and run it against the DX10.
Thanks and it was good to meet you today. I will hopefully pop a few videos up in the future that cover other Retro goodies as like i said it has gone a little off track.
Thanks for sharing , i was going to get an 891 but as i am so used to having a waterfall on my 7300 i think this radio would be a better option .I intend using it mobile decisions decisions.
My next radio will probably be a FT891 for Mobile and Portable, obviously the FT710 is a great rig and a totally nicer radio to operate but it is just a bit big for mobile and definitely no good for karting off the beaten track on your back. I suppose it comes down to your needs.

@@gtretroworld And I was thinking someone already experimented to find out what was possible (with trial use of the solder bridges). I will "Go to MARS", when I get my antennas back. Building work is getting in the way for now, but I have got a new long copper earthing rod installed today. Here's to 60m & 4m on my 710.
Great video. Tried this on my EU /UK radio but I'm still not able to TX on 27mhz? Updated firmware to latest version before the mod, bridged P51, did the Power/DSP/Fine reset but radio just behaves as before. I noticed that in the video the machine power cycles twice when you do the hard reset, mine only ever powers up once for the reset. Any ideas?
@@gtretroworld Thanks for the info. I must have been having a senior moment, I tried holding the DSP/FINE before the power and then keeping them held down a bit longer. That did the trick! All working as the video now. Cheers!
I’d like to request a video showing us where the 150mA SMT fuse in the DVI-D external monitor circuit is located. I have yet to find a schematic or board diagram on-line. Those with SMT equipment and skills could replace the fuse if necessary instead of sending it to Yaesu. Thanks for this video. Edit: I found the Technical Supplement for the FT-710. The “Fuse” that I imagine to be the monitor issue is located on the same side of the board that you show in your video (very accessible). From the Technical Supplement; “D5V” enters the MAIN-2 schematic sheet, passes through a zero ohm resistor R1860 to become “DVI5V”. DVI5V passes through ferrite bead FB1805 then PolyFuse Q1802, then Diode D1800 to pin 14 of the DVI Connector J1803. I am guessing the PolyFuse is the issue, but I understood that PolyFuses “Recover” from fault, when the fault is removed…….
@@PacTel54321 I would but I don’t have a FT710 here at the moment, this radio was apparently intentionally fitted with a resettable poly fuse probably due to all the issues with the FTdx10 and 101. I suppose it still could still be at fault or could even be a surge issue, as you probably know poly fuses aren’t the best with big surges so it could be another failure. Probably easier to check everything around that circuit. As soon as i get another in here i will take a short video.
@@gtretroworld I agree. I see that the DX10 originally had an 0402 "Zero Ohm" Resistor that was updated to an 0402 fuse; the latest schematic and parts list say 0.63A. The latest 710 shows a poly switch & also has a TVS network on the SCL & SDA lines.
Done this mod for a friend on his 710 done the reset still won't tx out of band unless its a japan version ??? How can I tell is there a difference with the serial sticker ??
Great video, thanks! I have an FT991a that I bought from GigaParts with a MARS mod. The mod only addresses the HF portion of the radio and not the VHF/UHF. Do you know if it's possible to modify that as well? Thanks again!
Thanks, Yes the FT991 is MARS/HF only. You can use service mode to enable VHF/UHF but it isn’t a permanent or ideal workaround. I will dig a little deeper and if i find anything i will let you know,
Yes it looks easy, so I did it with my FT-710 Field. But no success. He does not transmit on the 11 meter band. Only on the amateur bands. What could it be ?????🙏🙏
@@flyingdutchman1805 I presume it is a EU or US radio as they seems to be a good few Japanese FT710’s circulating. Anyway make sure the firmware is up to date, recheck your soldering for continuity and try resetting the radio again. Hope this helps.
@@gtretroworld Het is een EU set die ik van de week heb gekocht. Ik gaat er van uit dat de firmware die ik nu in de radio heb, oud is. Ik zal deze van de week gelijk even update. Mijn soldering is goed heb al gekeken met een camera.
Worth checking the firmware as it happened to someone else on here who had older firmware, why this was the case i don’t know but it was. Also try resetting the Radio again.
I used a solder rework station and very fine solder. I only used the hot air aspect of the solder rework station. It is more forgiving than a big sloppy soldering iron.
@@indridcold8433 I think most that are watching this are not very confident with working on expensive equipment. I normally don’t recommend anyone using hot air without experience or a quality tool as i have seen a lot of damage to surrounding components.
As far as I’m aware the FT710 won’t transmit 4Khz wide but i will look into this. I know for certain the FTDX10 has is it as I have one and it selectable in the TTBF settings. If i find anything i will check back. Thanks
@@gtretroworld I know for sure that 4k audio is activated on the American versions. Can you confirm for me if TBTF is activated after this change? If not, do you know a way to convert the version I use?
You have to open it up to add options like filters etc and the modification details are sent to engineers anyway and unless you’re not confident there is always an element of risk involved but to ruin the radio it would be rare. Thanks for your comment.
It maybe worth going back and checking your solder bridge as this has never failed with the few i have done. You can also reset the radio in the menu if it is easier with All Reset, hope this helps.
@@Industrialsoundfanatic I am not really sure as this and the others were checked and updated if needed before hand. I will say it is always worthwhile keeping up with the latest firmware updates.
Neil your video inspired me to go ahead of the MARS procedure with my FT710. Bookmark my channel if you like, I will post my video of my MARS modification soon.
I cannot see why Yaesu etc should not be allowed to offer 27MHz TX on their radios within the country's CB Radio Rules. In Australia, 4 Watts AM and 12 Watts SSB PEP. If the FT 710 could do that without this mod, I would be happy. I have an AX144 with no mods or extra power and I can talk across Australia on SSB easily at the moment.
@@stewheelie7874 I guess they could but i doubt anyone would pay Yaesu money for a 27mhz only radio. A lot are using these for 11m but most probably not within their countries rules. Yaesu don’t seem to care, same as the retailers who offer the modifications. I do see your point though.
Japanese radio regulations are odd. For example legal CB radios do not permit the use of a detachable antenna. So we can’t connect our piddly 0.5W to a roof top antenna or do field ops with an EFHW thrown up a tree for example. Because of this an HF rig operated by a legal and licensed Ham cannot be used for CB even if it could TX on 11m because it doesn’t have a permanently attached antenna. You can’t throw the radio up a tree and use a long external speaker mic either 😅 Surprisingly (heavy sarcasm) legal CB rigs cost as much as a decent ham rig over here. Go figure I think sums it up.
@@Tokyo1991.JL1AJE 0.5w for CB isn’t going to get you far especially if you can’t use a external antenna. As for using a HF Radio for CB it is probably a grey area in most western countries. Out of interest is CB Radio popular over there?
I would honestly say most opt for the MARS mod just for 11m and WARC especially on the older radios. I think MARS modified is just a term that everyone relates to wideband TX.
Maybe the manufacturers should get a clue and just open up all the bands once and for all ! Then if someone didn’t want a sh*ton of radios they could have a one and done . Or a two and done base and a mobile / portable rig . I’m sick of all the old FUDS with there holier than thou attitude nobody gives two sh*t’s about your self aggrandizing opinions.
MARS mod? WHY ? How many hams are on military MARS? Really......This is one mod that is outdated and not needed. Every time I look at a used radio that interests me, I check to see if it had the MARS mode. If it did, I move on. I personally would never purchase a radio that someone dug into and made a MARS mod.
You will find a huge amount of Hams choose to wide band their radios. I can imagine 99% aren’t military at all. Obviously for freebanders which is probably the main reason it is definitely not outdated and probably what keeps these companies sales going. Tbh I rarely purchase a radio that has been modified unless i know where it’s been.
Expansion done!
The FT works perfectly on all possible frequencies, as well as its ATU.
Thank you.
Great! Excellent thanks for letting me know. 👍
That seems a lot easier to do than the Ft-891 or IC-705. Thanks for the video!
