Hello mate nice to watch your videos spoke to you in m&s today I was on till

[@gtretroworld]

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.

wish they used physical jumpers, my hands aren’t steady enough to do that bit of soldering

[@gtretroworld]

Honestly if you take your time with a small iron it will be over and done in seconds, if you were local i would’ve gladly done it for you.

[@thestonerguy5276]

That seems a lot easier to do than the Ft-891 or IC-705. Thanks for the video!

[@gtretroworld]

Thanks, I have yet to have fiddle with a FT891 and IC705 but both are radios i fancy trying one day.

Nice clean job 👍👍

[@gtretroworld]

Thanks Andy 👍

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!

[@gtretroworld]

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,

Fantastic work Neil, great video 👍

[@gtretroworld]

Thanks Ben, Hopefully it will be of use to someone over the next few years.

Loving that yaesu Neil thats a nice bit of kit for sure and tempting me to buy one now..
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..

[@gtretroworld]

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.

[@m0ogy]

Thanks for the video Neil 🙂

[@gtretroworld]

Thanks Dave, hope you’re well.

Yet another mod where a blob of solder is used…. There is supposed to be a zero ohm surface mount resistor at 1/10 watt installed to make the connection.

[@gtretroworld]

There is absolutely no difference between this and a Zero ohm resistor, maybe the resistor would look prettier but that’s it. Even the Yaesu paperwork quotes use a solder short and probably every tech and shop is doing the same.
Thanks for visiting the channel.
