Great video! I wish you had a video on how to get the RS-BA1 remote control and Icom remote utility to work with the Icom 705. I love the amount of details that you put into your videos and how you lay things out step by step. This video helped me to order the XPA 125A. Thank you!
Thanks jimjinright for the positive feedback; appreciate you witching and commenting.
This video as well as part 1 are TOP NOTCH! The structure and content were just the perfect amount! I've been looking at buying the XPA125A amplifier to go with my 705 but had too many questions I couldn't find answers to. You answered all of them and then some! Thank you!
Thanks for the kind words. I presented it in a way I wish someone would present it to me...I had all those questions because I wanted to pair these two together. So glad it was helpful. Now, good luck on finding the XPA125B....
I appreciate this tutorial and the effort. Today, I'm finally setting up my XPA125B now that I have the radiodan kit for the 705. You provided me the motivation to get this station up. Thanks much and 73, de Randy N1PTB
Randy, hope all goes well with the set up leaving you with a new set of skills / tools.
@@HOAHamRadio seems to work like a champ. Thanks again and 73, Randy N1PTB
I bought this relay buffer on eBay and it works like a champ and addresses the issue that ICOM discusses in their manual. ICOM IC-705 to Xiegu XPA125B amplifier keying cable w/ RBI-1 . I love this amplifier and it works excellent with the 705.
Totally agree with your assessment; works like a charm.
I had been looking at this amp for my 705. Your video just helped me decide to go ahead and buy one. Thank you for the Buffer info I will use one of those. I am happy to spend a little more to protect my 705. Thanks again for the wonderful video!
Glad it helped Barn Dweller; this is a great pairing the the IC-705. Some have said the buffer isn't necessary; but I can't bring myself to taking that chance. This came about as I was trying to solve the amp problem myself and thought I would share it with others.
Enjoyed these videos. I'm more into QRP with the 705, but its good that these videos are here and got me thinking about the XPA125B as something that I could buy in the fullness of time.
So glad you found this helpful. I try to cover sufficient detail you could use the gear yourself, once you watch my video. 73
Superlative video. Far and above any other video on this subject. Fantastic job!
Thanks W8BI for the kind words. I was just starting in TH-cam and wish now my presentation equipment and skills would have been a little better. I was frustrated that no one was providing the detail on this pairing as it was important to me...so figured I'd do it.
GREAT video! Thanks for the information on this. This video prompted me to get the Radiodan kit and get out there with the new amplified 705
So glad it helped. The pairing of these two has been a goal of mine for months; it is my preferred remote kit. I figured I needed to conquer it and share it with others.
Thank you for this video. It really help me set this combo up.
You're welcome. The IC-705 is my emergency radio, and I wanted something to give me the extra punch when needed.
You got me thinking about the ARB and I think I will buy one. Like you said the IC-705, which is what I have is very expensive. I would use an ARB with an AMP to save or hopefully protect my radio so why not do the same with a QRP Rig. HOA Ham Guy thanks for your help as I only recently received my IC-705 and Xiegu XPA 125B. See you on the air, Robert N0YG
Thanks for the positive feedback Robert, and have a blast with your IC-705! Love mine.
I've seen that issue with getting the tuner to cycle. The amp needs enough RF energy to get a reflection back to measure.
I beat my head against the wall for a while on that one, till I thought, "it can't be me"...thanks for the confirmation.
Great video and tutorial - thanks! 😀
My pleasure Barry. This was a journey I was on for myself, anyone watching got the benefit of what I was learning for my set up.
The XPA125B manual says to tune for low SWR in CW mode, but doesn't give specific instructions for tuning the G90/XPA125B combination. Radiooddity emailed me to set the XPA125B PA off, key the G90 mic with16 watts AM (carrier only no modulation) then initiate XPA125B tune. After XPA125B tuning cycle completes, reduce G90 power to 5 watts or less, turn XPA125B PA on. Following these instructions I get an SWR of 1.7 or less and good SSB signal reports on all bands, 160 - 10 using my 71' end-fed non-resonant antenna.
Thanks for that feedback Jon. That's interesting they strayed that far from the manual in using the Amp / Tuner with the G90. To get the Tuner to work with the IC-705 I had to push it with RTTY. I sure with they would update and expand that instruction "Manual".
Great video; thank you.
My pleasure. This one was definitely for me...meaning this is how I use it and the entire reason I purchased the IC-705; to have light weight portable, but power when I wanted it.
To tune the XPA125b, RTTY works, but you can also use DV (DSTAR) mode on all bands.
Good to know Kent, thanks for the tip.
I understand the XPA125B has a CI-V interface, I am wondering if a software update to the Xiegu to improve it’s paring with the IC-705?
In this Facebook Group I started, everyone recommends against updating firmware....often leads to bricking the unit. Feel free to join and ask away facebook.com/groups/xpa125b/?mibextid=oMANbw
while following your direction , i keep getting a reverse high power ...popup screen and my swr on the right it was like 2.3....2.6...even when i went to transmit it would say reverse high power..any comments
Its been a long time since I've had this set up operational so I'm a bit rusty. Here is my Facebook Group on the XPA125B...lots of people there to ask questions: facebook.com/share/3HbNUd6F6wXbwihH/
Thanks for this…
Was just getting ready to reply to the previous comment; I see you found the video where I used the internal turner. I also, just minutes ago, created a playlist for the XPA125B.
What is the power required by the amp, during transmit and on receive/bypass? Wondering about battery and solar requirements for portable use.
Dan, you are asking really great questions, and now I'm wishing my memory was better. The video series I did on the XPA125B is now several months old and I'm drawing a blank. As far as portable use, I ran the IC-705 with the XPA125B remote with a 30Ah Bioenno and a solar panel for ~6 hours and barely dented the battery. Bioenno told me I could use the 20Ah and I would be fine; I went with the 30 since I knew I'd be at it for hours. I rand the X5105, then G90, then IC-705 and for most of that time was powering a laptop through an inverter and charging cameras, all from the same 30Ah power source. I only show the tail end of the event using the IC-705 but I do talk through the entire event of running the X5105, G90, then IC-705; here is the vid th-cam.com/video/7pclNsBmupk/w-d-xo.html
one reason of many that an Icom 705 was bought because it could be paired with this XPA125B tuner
Me as well. I made both purchases before there was a HOA Ham channel...I wanted to be able to be light weight portable, with power when I needed it.
Where did you get the patch cable from 705 to amp antenna ports?
Here is the kit I purchased from eBay seller, RadioDan: www.ebay.com/itm/143898454710?hash=item2181042ab6:g:LyIAAOSw3~df5qHz&amdata=enc%3AAQAHAAAAsPETEEFhTsoOvdpz4C9WmNDvcE2Lo%2BPSIeNdZckQAs3sZEt3UO2teBh8b1IzTgSgq1kviVGWVEY3LsZ9rB1KOURfYP3sVwHEnGEBdRVIQ29YHx9cd0TzXpTx2JKE0H9NkvcEFPy5tuevwQ%2B41gnBZ0mHrgwnhsNQJilj2RvdFMf5mshjoy%2BoqIScF%2BeNOEca4STppdjcU4lsTGusHiqQv6DN9WAl50B7wccIBrwBW6Q2%7Ctkp%3ABk9SR-rW6Ym3YQ
He sells individual cables as well, and responds quickly to email requests.
Does the XPA125 allow you to use FT8 or Winlink on the IC705?
Dan, I don't use digital modes, so I'm not qualified to answer on the specifics. I've created a Facebook group for the XPA125B, I think some of the members use it for digital; asking them may be your best bet. Here is a link to the group: facebook.com/groups/xpa125b/
Thanks so much!!
Bob I have my G90 and XPA125B hooked up through a CE-19 and have questions. I think antenna tuning is working but I have yet to see anything out of the amp. No power shown going in and nothing indicated on the output. Also the band will change on the amp when the G90 is keyed. For example on G90 the band set on 20 the amp will switch to 17 and on 40 the amp goes to 30. power on the G90 is set at 5W. I am transmitting into a dummy load. Any ideas? I agree, the manual is as poor as they come.
Ralph, if everything is set up correctly, PA on, ATU on, Band select in Auto, with correct cabling between radio, amp, CE-19, everything should work. Has this ever worked for you, or is it new out of the box? If new, perhaps its defective?? Here is my video specifically with the G90 paired with the XPA125B
@@HOAHamRadio The amp is new. I have had the G90 working correctly on FT8 using the CE-19 but switched to the digirig mobile to get rid of the wiring clutter. Wishing I could figure out a way to continue using it with the amp I reluctantly went back to the CE-19. I’ll double check the cabling but right now the G19 is working contentedly with the digirig and contact Radioddity about returning. Thanks.
@@ralphday7573 Please let us know if you resolve this issue or decide to return the XPA125B. Thanks!
@@jonmcadams5401 Jon, for the time being, I am not using it with FT8. I think I may be OK using it with POTA. Will just have to see! I’m hoping you are campaigning for a better manual. It is needed and would be appreciated!
Can this amplifier be modified to tune to 11 metres ? 🥃🇦🇺👍
It will not do 11 meters...it does want to be on a specific ham radio band.
Is there specific setting on the 705 to allow the mic to key transmit on ritty?
Yes there is, that's what I demonstrate at ~ 18:50 in the video. Thanks for watching.
