This is just what i need! I'm trying to minimize my radio equipment (running out of space) and whith this mod, i can remove the cb (older, big station model) I bought the 705 for it's size and HF/vhf/uhf combination, adding cb capability is just awesome! Thanks Andy! ❤ Subscribed!

thats why i love my ft-818 everything in a tiny box and i can use it anyware

ALWAYS Awesome stuff from Andy Kirby , cool mate

[@JohnBerry1]

I can confirm that this works. I used my solder station with an extra-fine-point tip at 700 degrees with an exactor knife and a magnifying glass-lamp (LED) to heat up the diode-spec on the lower left bank and was able to lift one end of the diode. I put everything back together and worked like a champ. I'll be posting some pics to FB soon

I really enjoy your videos. You're like I was as a kid running around with a radio. 73

[@andykirby]

I was like it as a kid too 🤣

[@toddi1971]

did this to my 7300 ... i recommend to use filter3 on FM because otherwise deviation is too large for most CB radios. You can store the channels in memory and have a very fast channel scan and can use the buttons on the mike for switching channels .. cheers! very nice setup!

Awesome, you have and esk8 too. Good vid, I want to mod my 705, I already did it to my 7300. The 705 is so much better for portable ops, I am thinking of getting the backpack just for skating around.. :D 73's N7URH

[@SBPepperminion]

There's a catch. In the U.S. and some other countries, its 4 watts max when using the citizen's band radio service on FM and AM, but 12 on Single Sideband. Does the radio know to lower output, or do you just have to be careful?

[@bumblebee-mygt867]

I wonder if the manual has details of what diodes do what frequencies. Back in the 70s the Icom IC 240 used the same diode synthesiser control system to activate channels

[@PhilMozchops1974]

superb still have my Harrier cbx from tandy. just think they were illegal in the 70's until everyone started to say up yours government!!!! lets hope this will happen again with P E V 's. great video Andy.

Great Video Andy! 🙂 I was thinking of using my cb radio for FT8 🙂

[@AdamSmith-fe9jf]

Any rides on the Vapour coming soon?

[@xxxenricop]

A curiosity. What about applying pressure on the diode with something like a box cutter o a small, sharp flat head to break it? Would "incapacitating" the diode not achieve the same result?

[@TonyLing]

You can snip them with a fine pair of side-cutters, but it does risk lifting the pads. I find two soldering irons is the best method.

[@jcmo69]

Just tell them to bash the thing with a rock why don't ya?

[@ads3453]

Its been a long time since I have been near a CB moved to HAM stuff a long time ago and never looked back. However I do remember there being a power limit on CB or at least when I was using them of 4 watts. Isnt the 705 capable of 10 watts ?

[@OllieVK]

705 is 5W on its own battery. Can go up to 10W with an external power source, but you can set that in the radio as well. It's 5W for CB (at least in Aus anyway).

[@mrcleanisin]

Mirrow image is distracting. Are there any digital CBs?

[@-The-Darkside]

I'm looking at getting into radios, don't really know were to start but I will say I laughed at the end of the video as I'm also a synth man. Like I can see you're a Roland fan. I had a Roland w30 years ago and more recently a JDXi and still have the MX1 mixer from the aira line. I've gone full Analogue lately. Must be some crossover there with how the mind works. Anyway cool video man. Subscribed and hopefully I'll figure this game out at some point.

[@andykirby]

Haha! Yeah great minds think alike! I'm going to do a video soon about getting in to radio. Thanks for subscribing, welcome to the channel.

[@Patrickjdee66]

Cheers matey , not sure I would be confident enough to take a chance messing with the 705 inners, but was good to watch, I’m literally back to radio this year, used to have a CB in the 80s, an old maxcom 4e lol, got my ham licence in March and got a bit bored with Ham so bought a Randy 3, just need to get an antenna outside , daft question coming up, could I use a mag mounted antenna in my loft, I wanted to buy the Sirio 5000, would it work? I’m sure the SWR would be all over the place, I almost pressed the buy button earlier but held back, all the best mate

[@andykirby]

Right, so hold fire on the sirio, it'll never work great in the loft unless you get really creative and make a massive groundplane or loads of radials underneath it, mobile antennas are groundplane antennas so they need a really good groundplane. The best sort of antenna for cb is a 5/8 wave vertical 30ft above the ground. Yeah it's gonna be big but that's just how it is! Alternatively the sirio boomerang on a pole on the ground or mounted at gutter height (or higher) is a smaller option that still works well. Cheaper option is a wire dipole from ebay for 11M on a 10M telescopic pole from amazon on a heavy parasol base! A lot of CB action is on SSB but there is activity on FM, you'll likely need an amplifier too as everyone runs a bit of power these days to get over the noise! I'll do a video on all this soon!

[@qrphfradio7753]

It's easier to just crush the zero ohm resistor with a thin pair of snips..That's the way I've always done wide banding on mine,, that way you still have the solder pads in place should you want to add a blob of solder to return it back to amateur bands only..

[@andykirby]

That's a pretty good tip, they are tiny diodes gotta be carefull not to pull the pads up!

[@qrphfradio7753]

yeah you dont want to be damaging the pads, just use light pressure when crushing the component, it doesnt take much pressure with them being tiny..

[@geraldscott4302]

I have an Icom IC-718 and an Icom IC-728, both full coverage HF ham radios. The 718 is a fairly new radio, has been around more than 20 years, but you can still find them new. I understand they are being discontinued. The 728 is a much older radio, last made in 1992. They are both much larger and heavier than the IC-705. They are intended to be used as base stations. I consider the 728 the best radio, it has a triple conversion superheterodyne receiver, something you just don't see anymore. It does not have menus and is not programmable. Both put out 100 watts max. The 728 has what is known in the U.S. as a MARS mod, which allows it to work on 11 meters SSB, both transmit and receive. The 718 can be converted, but it is much harder to do, and I don't want to ruin it. I would never try what you just did. Good way to ruin an almost $1400 radio.

Can ANYONE answer this?

[@tracym427]

@@DontM8-__- it won’t. I did the mod and it only will TX up to around 457 mhz. If you have another radio close by monitoring gmrs and you are transmitting on same freq after mod you will hear it on other radio but I think it’s coming from the portion of the radio that hasn’t went thru the amplification circuit yet. With a watt meter you will see there is virtually no output power on gmrs. Maaaybe .01watt. Everyone else I have found is having the same results after the mod.
