- As a IC 705 owner I wanted to make this video to show how I was able to set up the new radio with an external amplifier.
I have been seeing threads on the ic 705 groups.io email chain where some people were wanting to make this work.
As an added bonus, I also have the LDG Tuner hooked up in the mix and it all works great.
I hope this video helps someone.
Thank you for watching.

Hi Dan excellent job thanks 73 from kb2uew
Good job Dan. Awesome first video!
Thanks Danny. Proud of you little brother. Dios te bendiga.
Aww, thanks sis. Love you. =)
Dan, Thanks for an excellent video. I've been contemplating an IC-705 purchase and wanted to make sure that additional transmit power was a possibility. You've shows that it's not too great a challenge.
Thank you, Nate. It really is a great radio and I don't regret the purchase for one second. I thought I was going to be missing the power on the 2m/440 side, but I have been using it in my truck mobile and have had nice long distance simplex QSOs as well as repeater QSOs that have not left me wanting at all. Last week I set up on the side of the road with my tripod and my Arrow satellite yagi. I had a 2m FM simplex QSO with a station in Tucson that was 125 miles away from my location. I was on a drive up hillside about 500 feet higher than my surroundings. It was awesome!!
Great video. Just picked up a 705 and its great to see how to jack up the power when operating vehicle mobile at a park or such.
Thank you Dan for an excellent video! I have the 704 buffer but did not use it and blew my amplifier (Xiegu 125B). Luckily it was replaced under warranty. Some say the 704 is not needed, but after my experience and reading, I find if used it is very good insurance. Maybe Xiegu or a third party will figure all of this out. Thanks again, Rudy
Thank you for watching, Rudy. I am sorry to hear about the amp, but it sure is a good thing that it was still under warranty. It is funny to hear peoples thoughts on the 704. I have heard "you don't need it", but I have always used it in the shack with my IC 7300 and I have never had any issues. It is better to have it and not need it, than to need it and not have it.
Good video. The 705 is very easy to amplify. The problem is that many HAMs do not know how to create, or understand electronics theory so they depend on fully built solutions when sometimes they just dont exist. I am glad you shown them one method. The 705 is an absolutely kick @$$ radio. Worth every penny. My one and only complaint is the lack of USB C--- what were you thinking Icom using an absolutely obsolete micro usb port that is flimsy and prone to breaking.
Since you mentioned having a KX-3 I thought I would share a quick tip to hook up the Elecraft KXPA-100 amp to the iC-705. The connection point on the amp is the RCA PA key connector. The other end of the cable is the 3.5 mm stereo jack that goes into the ALC connector of the IC-705. It's tip to tip on both connectors and ground to ground as well. Don't use the ring on the 3 pin connector. At first I was going to make the cable but then I thought why not use a standard a 3.5 mm to two RCA stereo break out cable of which I have many. Just don't use the red RCA cable. Maybe tape the end to avoid confusion. When I ohmed it out the white RCA connector tip connects to the tip of the 3.5 mm cable. I connected it up and it engages my amp just fine. I also added a 20 ms delay for the amp to kick in through the IC-705 menu. Hope others find this useful.

@Mark Herman Glad you found my message useful. But if you have OCD really bad you would arrange the letters CDO... :)
Great job Dan! Liked the Video!
Thank you, James. Have a great afternoon!
Great job on the video . will help when i decide to hook up an amp to my 705. Thanks 73 WT9J Terry
Glad you enjoyed it, Terry. I hope you get as much enjoyment out of this radio as I do.
Thank you for the informative video.It is guys like you that make this hobby interesting by sharing you information with the ham community.
Good job Dan. You would never know it was your first video. 73. Liam. GM4VYQ
Dan Smith thanks terrific an excellent video great job my friend 73 from kb2uew
Excellent video and very helpful. Keep at it!
Very helpful video. Thank you!
Greetings DAN. Thanks for this video. I am trying as well to hook up my 705 to a tuner and amp. But I can’t help but notice that your meter to left of frequency reading was hitting the red zone. Is this on power or swr meter? Hope you can clarify. Thanks.
Great video Dan! Very helpful! I hadn't seen your video yet, but I ended up buying a little buffered keying interface on eBAY to accomplish pretty much the same thing. BTW - are you sure this is your first youtube video?! great stuff!
Have you tried controlling the Juma PA-100D from the serial port on it ?
Hi Dan, great video! I have an odd issue here - it all works as you describe, but when I switch off the IC-705, the LDG's SWR LEDs for 2.0 and >3.0 come up on. This is regardless of whether the IC-705 TUNER button says ON or OFF.
Does the same happen to you and any idea on how to address the issue?
Hi, thanks for the kudos. I do remember that issue and if I remember correctly, you need to disconnect the tuner cord from the tuner for the battery link to disconnect and turn off the tuner. If not, your batteries will not last as long. =) All the best.
@dansmith-n7dsx232 thanks, that sounds like it! Really odd behaviour.
Good job, thanks
What power supply should I get for all that kind of setup?
Nice job! K1EOD
Thank you, Dan.
Hey I appreciate the video! Good job. I would assume, if you wanted, you could drive your AL-811 and maybe get about 175 watts out. 73 de WA3RSL
Thank you, Frank. That is a great idea that was the farthest thing from my mind since I couldn't imagine lugging the AL 811 boat anchor around portable. That said, I will be trying it when I get back home. Thank you again for an awesome idea!!

HF only?
Dan,
Nice job. To the point, no rambling, and good info. I'm new to the Ham world and have been looking at the 705. I am interested in being able to hook it to an amp like what you have done so I can use it QRP or as a base station. Could you add the products/links you used in the description. I currently have a Kenwood D74 HT to get started. I saw your AZ magnets and your N7 call. I am in Queen Creek. Thanks again. 73 KJ7RGD Brian
GM Brian,
Thank you for the comment and for watching the video. I am glad that I was able to raise some questions and I would be happy to show/tell you more. The D74 is an awesome radio and it was my first real rig also. It is still my go to HT. On Franks recommendation, I am going to post a video of the IC 705 running my Ameritron Amplifier, but if you re in QC, you could come by and see it in person.
Your timing is also pretty excellent as we have a local ham meetup at Desert Mountain Park, in Queen Creek, tonight from 5 til 8 or 9. We set up radios and chat and help each other out. We are also testing tonight, so if you wanted to upgrade, or know anyone who wants to get licensed or upgrade, you can do it right here in your hometown.
The last thing to mention is that we have a simplex net every Tuesday night on 146.580 at 7pm and we would love to have you join in, say hello, and maybe even take the reigns as net control some day. QC is super radioactive and I am glad that you reached out. Hope to see you this afternoon.
I am adding some links above to the stuff I am using in the video.
Have a great day!

@@dansmith-n7dsx232 Wow, that is good timing, I'll be there. I live a few hundred yards NW from that park. Thanks for the info. I'll reach out to a friend of mine who is looking to test and see if he is available. I took my General a couple weeks ago in Mesa and my Tech a couple weeks before that in Chandler.
Nice video thanks for a couple of good ideas. 73 KE8JWE
Is it the Juma PA100 power amp?
Can't we just plug a MX-P50 into the key Port? I have a Mat-705 tuner with my 705, just got the MXP50M, im a noob so i don't want to fry the 705 :)
GM, I am sorry to say that I can't answer that question. I don't have the Xiegu components to test the connections, but I would highly recommend signing up for the email group as that topic, and those particular connections, have been discussed at length. If you send an email to ic-705@groups.io you will receive a welcome email within an hour or so that tells you how to search the knowledge base and to post emails with specific questions. The group consists of IC 705 owners and hopefuls around the world and many of them have had the radio for some time. I hope this helps.

@@dansmith-n7dsx232 no worries Dan, I joined the group earlier today, the ic 705 has options to turn it down to 0.5watts so may have just manually use the Amp 😉
You may want to use an external keying circuit. Nice little amp, but direct keying could damage your radio. Check out Kevin Loughlin's videos czcams.com/video/k8dwJMOdEMI/video.html and czcams.com/video/0uQbeFhWh2A/video.html
