Perhaps the nicest home brew rig I’ve seen yet. I love the military inspiration.
Very nice. Got inspired much of you kit..Just finishing my own kit.
Great job, I am building one right now. got inspired by your nice work. got the antennas stuff. Now going for the frame, aluminum pipes. TNX ,73 de 4x6yw,Israel
Thank you very much my friend, I hope yours turns out great and operates well. I'm sure you will have a fun build your version. Many blessings to you and your family.👍😎
I just realize where your location is Yoram, I pray you and your family are doing ok despite the circumstances there in Israel. I pray YHWH will protect and keep yo all safe from harm. 73's dear brother. N1TZU...Bob..😎
all i can say is your an artist! details man details
Thanks Mark, I've also use two of them on a portable latter line fed dipole that I take camping...they allow me to string out almost any length needed for operation.....fun stuff.
Thank you for the complement Scottie, It is a fun hobby and also this unit was fun to create. As you can see I like to build stuff. Many blessings to you friend.
very good !!!!
CQ this is N1LRF What a Very nice job you did! Hats off to your and 73's
This is one of the coolest UA-cam vids i have seen in a long time! Its given me so many ideas. Love the fly reel idea.
Thank you rab1978uk for the complement.
Youre welcome. If you can fabricate a great piece of kit like that, you should show us how you did it. come on , don't be shy!
rab1978uk Thank you again. It was quite a project and it took some time to fab. Maybe when the weather gets warm again I'll put together a more detailed video pointing out all the pieces and try to explain how I fabricated it all.
Thanks, that would be great!
Looks great ! I too have a 897D would like to make the same pack and such. Would be fun to bring to our next field day !! Nice work !
Thank you MrBlueman722 for the complement. It was quite fun to build and it took some time though. I use this mostly camping. 73 Bob. N1TZU
Beautiful... My compliments. Well constructed rig. Just awesome.. hello from Texas
Hello humpty79ify, Thank you for the complement. It was fun to build. And is fun to operate. It can be a challenge when using just the vertical antenna. I use it most of the time though on a table hooked to portable dipole. So thank you again and may Yahshua (Jesus) shine HIS blessings to you and yours. 73. Robert.
Your welcome HAM R. Im working on mobile c.b. manpack. I'm gonna use an army ammo box for the 7.62 round chain rounds I acquired when I was in the service.. but Sir it doesn't compare to yours. again my compliments on your rig.. outstanding. Whiskey 07 out..
I like the fly reel for a wire antenna holder. Nice!
Well and very nice done, congratulations!
I don't mind at all Annon Ommus. It works very well and easy to deploy. Have fun friend.
I love the use of the fly reel; I'm stealing that idea, hope you don't mind...LOL
Absolutely nice set up!!! I want to build one just like it...
Thank you for the complement my friend. I built a new version. Check it out here, ua-cam.com/video/FJj91RFeA28/v-deo.html

Thank you slickjimmy, I,all check it out later when I get home from changing out a heating boiler for one of my customers.
Great looking rig & nice audio! Would have liked to see you using the head set.
Hello Criag, I never did any video's actually operating this rig. I did make a short video operating the next version of the manpack though here ua-cam.com/video/419ago_Rtow/v-deo.html the bands were not all that great at the time so didn't make any contacts. Thank you for viewing and many blessings to you and yours. :-)
Looks like a fly fishing reel, guessing it's for long wire antenna? Great fab job.
BEAUTIFUL Equipment !
+dirko giese ...Thank you very much my friend. I have a newer version. If you have the time,check it out. Many blessings to you and yours. 73's...N1TZU...Bob.
Hey OM. I've got the FT-857 mobile using, where can fedend, crusing now Central EU for fun. OD0845 73's from dirko
Great setup, very nice home brew!
Замечательно сделано. Мне очень понравилось. Всего доброго из России.
73.
Thank you very much Ebacherville.
Hello theanti2007, Thank you for comment. And yes it's not really the type of radio for real bad weather usage. But, (1) I had almost all the materials in my radio stockpile to build it so I didn't spend much money at all. (2) It was a fun project to build. (3) And it works just fine for what I use it for. And yes, Your Codan is a far superior radio but at far higher cost. Thank you again and may the Great Creator bless you friend.
Thanks for your blessings..
This is just plain beautiful. Very impressed at your work. Thanks for sharing with us. Would love to see the Frame available with an "Add Your Own Equip" kind of thing. Any thoughts of building some special order?
Hello ThePauperPrepper, Thank you for the complement. It was fun to build as well as operate. I would say it would be too costly if you consider the time it took to fabricate. Plus it's fabricated around many scraps, I happen to have laying around. So, to gather all the materials to make another the same way, I would have to purchase many items to make the same thing over again.
Hello Farley, Thank you for the complements on station...I have no static pics yet...I'll try to get some posted soon...the interface of headset is some what home brew...small piece of cat 8 cable to the back of 8 pin Yaesu mic connector mounted on aluminium plate...then 8 pin Yaesu mic jack and coiled cable to military PTT switch which plugs into headset...of course you have to figure out each pin on radio to match with headset.....
Beautiful.
Thank you very much D Fisher. Many blessings to you and yours.
Thanks!! Very helpful!!! Great build man!!
I would LOVE to see more detail on the handset conversion. I'm looking to do a similar thing with an H/250 to adapt to my 857 as well as my Baofeng HT. I was thinking a 6 pin connector with the threaded barrel like is found on the older Yaesu and CB radios with one male in on the handset and female ends on separate connectors for the 857 and the Kenwood style two pin for the HT.
What I'm finding in my research is that the mic in the handset is dynamic and therefore not really usable for these purposes as the volume would be greatly diminished.
Make another vid for that handset and the Sordin headset conversions, PLEASE!!!
Also, awesome manpack rig. It's a work of art!!!
James Sherrill Hello James, All the wiring details are readily handy on the web for the H/250 handset. Look up " H/250 handset pin out " and you should find what you need. And yes the H/250 is a noise cancelling element so you have to close talk it,but it will work with the FT-857.. As for the sordin headset. I had to do a complete revamp on wiring and replace mic in boom with a eletret mic element and feeding it with 5 volts + off the Yaesu FT-857. It's not too hard, just took a little time to figure out a way to wire it all to a 8 pin adapter. You will need 7 of the pins to make all wires separate to the sordin headset.. 2 for PTT, 2 for speakers, 3 for eletret mic element. One of the 3 being the 5 volts + of course. I hope this helps my friend. Many blessings.
***** So you have NOT found the volume levels to be too low sue to the dynamic mic and higher impedance speaker of the handset? That sounds like the confirmation that I needed. I'm gonna order one off eBay today!!!
I've gotten a set of the Racal RA5000 vehicle high noise headsets and am playing with those of late. I can't wait to see how that all pans out but I'm anticipating rewiring that completely like you did with the Sordin.
Thanks and 73's. KD8TQS
James Sherrill Hi again James, The h/250-U handset I have seems to work fine with FT-857d. As far as other radio's, I'm not sure. And yes, the Sordin headset I have, I did a complete mic,wiring,PTT harness replacement to make it work with FT-857d. 73's and your welcome my friend...Bob...N1TZU.
I probably would have used PVC instead of copper pipe. It would weigh less...unless you're using the frame as the ground for the whole thing. Thanks for the video. This looks like something you would've seen in Viet Nam. :)
Thank you Sabatheus for your comments. And yes, I'm using the frame as part of the counter poise on some bands. The unit is not too bad in weight. It's about 37 lbs total. Most of the time when in use, it's on a table while camping.
Outstanding design! Love the H-250 Handset. Did you build an adapter to the Yaesu mic jack ?
Thank you very much for the compliment. And yes, I did build an adapter from the handset bulked male plug to the radio input. Many blessings to you and yours. 😎
Awesome build! Great job! You have inspired me to build my own backpack/manpack radio.
Thanks for sharing!!
May I ask what type of operating time/range do you get out of the 10 AH battery?
Hello Raymond, Thank you for the complements. As far as operating time. That all depends on how much power you run and how much you transmit. But, just to give you one of my latest adventures. Here in Maine we have a state park called Camden Hills where Mt.Batty is located. My wife and I did a late summer last of the season camping trip. While there I got up before the sun came up and hiked to the top with my station. I reached the summit when the sun was coming up about 6 am and set up and started operating about 6:15 am. I continued operating till about 11:00 am. My battery only dropped 2 volts and I was running an average power output level of about 60 to 70 watts. So not too bad. I would say if you ran a lower power level like 30 watts you could easily operate a good part of the day. Hope this answers your question. Have fun...73 and God bless my friend...N1TZU...Bob.
Thank you for the detailed answer! Yes, this helps a lot. I'm really impressed with the operating time of a 10 AH battery. Maybe sometime we will meet on the radio! God bless you and your family also! KD8HVN

Hello again Farley, The mounts are from Diamond Antenna's. One was an old used one from my parts box and the other was a new one....Hope that helps...Bob
Hello Aaron, I can only make a guess.I used about10 feet of 1/2"copper and about12-1/2" copper tee's..4- 1/2" ninety's and 4-1/2" copper cap's for the feet...the rest was scrap stuff from my parts box's of screws-aluminium plate-one old antenna mount-one new one-old hiking pack straps-etc.etc. So,I would guess everything but the radio and tuner cost roughly-$ 700.00 But bare in mind there is a lithium ion battery and SGC vertical antenna that was the bulk of that cost.Hope this info help..Robert
Can you do a video on building the farm for this man pack ?
Cool 😎
Thank you very much..👍
Nice, good work
Thank you much for the comment. God bless you much.
VERY GOOD FRIEND SUPER!!!!
nice setup!
Cool stuff I love it
nice job ,y friend 73 and good dx
Wow nice. I am working on one
very cool!!
Thank you much.
Nice rig.....
Great,...thanks a bunch...
Fantastic design and production. Do you still need the counterpoise wire for the hf whip antenna or the frame is enough ?
Hello Ham slice, Not that I know of. But, It's not too hard to do. It just take a plan,patients, and a bit of fabricating ability. I'm sure you can make one. Put you mind to it,take you time,and I'm sure you will be happy with your finished project. May the Great Creator and Savior of the world bless you and yours. Robert.
Here is the link. Its for an 817 but i think they have others. Ham Radio station+Antenna Tuner backpack frame for YAESU FT-817 LDG Z11 LDG Z100
I request you to turn this into commercial products for sales. I have many customers asking same kind of products. I am sure we are to help and satisfied their needs to whom are interested to own one, Too bad the FT-70 is no long available.
I no longer have this set up. I built a new manpack. Check my other video. Many blessings friend.
Awesome manpack and video. Is it possible to for close up pics/design plans?
What would it take to get the h-250 handse working as in the other guys video? He mentioned it didn't require any modifications.
Hello abiffmaster, This set up was all on the fly fabrication. So, I don't have any design plans. As far as the h-250 handset, I'm not quite sure what your referring to with another guy's video. But, I didn't have to make any mod to the handset to get it to work with the FT-857, I just had to figure out the wiring and make an adapter. Many blessings friend...N1TZU...Bob.
***** Can you share with me the wiring for the handset? I have the same rig.. Thanks.
Question, what settings did you need to change on the radio to work with the LDG At-100Proii tuner? I have the Y-Acc Cable but I can't get the tune button on the radio to work with the LDG tuner.
I want to build one, super cool. About how much did all the supplies cost (not including the radio or the tuner)? Thanks for the video.
-73's Aaron K0ARM
hey man, you should share some spec on that one, i would love to build that one for my new 897
Thank you Hammer USN. This was the first one I built. And, I have no spec's for this. It was all done in my head and then just built. It's probably sounds weird to some people but, when I want to build something, I can see it in my head before I start.
+Ham R. ok, that's cool, and nice job,
I know that this is an older video, but would you please let me know where you got those Antenna mounts that you have riveted to the frame?
Sure can Navy Davy right here..www.hamradio.com/detail.cfm?pid=H0-000193
Ham R.
gaaf die wil ik hel koopen dit aparaat
What was the distance between the two? Thanks.
Hello again,
I have a question about the headset adaption.. Does the Sordin have a low impedance dynamic mic..? If so, how did u get around the low transmit and receive volumes? Did I have to amplify the headset somehow?
Hi mastershimself, I have found the Sordin does have a low impedance mic. So I only use it on single side band and use the audio processing features in my Yaesu FT-857d radio to over come the issue. The headphone speakers seem to work fine but do sound a little thin. But that no big deal. So, to answer your question. If you are going to use a Sordin headset on a radio without some kind of audio processor, you will need to either change the mic element to a 600 ohm element or figure out some way to amp it up to drive the audio circuit in the radio. I hope this helps and gives you some idea's.....
This is awesome man!! My question is regarding the ptt connection to the radio. Does your headset have the tp120 jack or is it a pin type? I read below your comments on how you wired the system,(8 pin from the PTT?) but i was wondering what ptt you are using? Nato Version? I was hoping to rig a similar system and currently have a srs tactical avenger headset, with a tp120 nato pin for ptt connection.. any info is greatly appreciated!!
Hello mastershimself, My headset is the MSA Sordin type 75310 with the tp 120 pin type connector which plugs into a modified Nexus U94 PTT. I replaced the end that plugged into a HT motorola with a coil cable off an old hand mic with 8 pin Yaesu plug. If you look close at video you will see a home brew aluminium plate just to the left of FT 857d volume control that has a 8 pin female connector for headset and a military style connector for a H-250/U handset as well. I hope this helps you. 73's and may YHWH (God) bless you and yours. N1TZU...Bob.
Hello slickjimmy76, That would be cool if you could post a link to where on ebay these are for others to see. Thank you.
Hi... Is that your drag wire connected to the fishing reel? Awesome job with the pack!!
Hello Scott, That is what I use as a counter poise wire. I suppose one could drag it behind, if that person was walking and operating at the same time. I have not done attempted that yet on HF. I either set up at a table while camping or set up portable somewhere after hiking to some spot. 73's and God bless...N1TZU...Bob.
Much better idea than walking around with HF! Nice setup. 73s.
Scott Forbes Thank you again my friend.
How much does that beast weigh?
Hey
Great setup...
I'm wondering,..what do you do for counterweight (radial) in the antennas,...are they just grounded to the frame or...???
73,
Tommy - OZ1TMA.
Hello tman855r, The counterpoise is a wire on reel mounted to frame. It can allow about 50 feet of wire if needed.
Great job!!! What is the type of the field microphone?
It is listed in the description. A H-250 Military hand set. Many blessings foldesf.
Yeah, sorry I missed that. All the best for you, 73'
Wow, looks great. Where did you get the shoulder straps and padding?
Hello Ed, Thank you for the complement...The straps I scavenged them off an old mountain pack that was not useful any more. The padding is foam pipe insulation... 73's and many blessing to you friend....N1TZU...Bob.
I have another question related towards your manpack
Is the radio and tuner grounded to the frame assembly using short grounding wires between the frame and radio/tuner ground lugs?
I have my manpack setup, a ICOM-7000, IT-100 tuner, Lithium battery and a alumium frame. Im getting what I believe is a lot of RF feedback through the radio. The screen flickes and bounces around when I attempt to tune to a specific antenna on HF. This is using 15% of the radio power and it blew the inline fuse between the battery and radio on the negative side. The radio and tuner is ground to the frame via the mounting bolts/screws but no ground wires as of yet. I will install these now and reevaluate.
Any help to reduce what I believe is RF into the rig would be greatly appreciated.
Antenna is a MFJ-1979 vertical extendable antenna.
Thanks,Ray
Hello Ray, My radio and tuner are only grounded to frame via mounting bolts with no RF feedback problem. But also bear in mind my vertical antenna is a $300.00 helical wound 9' whip that can some what tune from 5.0 megs to 30.0 megs. The antenna may be your problem. If your trying to tune an antenna that is way to short for the frequency than that may cause a lot of RF feedback. Also the mic cord could be picking up that RF. Try setting up a temporary wire antenna close to the frequency you want to transmit on and see if you still have the issue. Hope this helps..73 and God bless...N1TZU...Bob
Bob, I am curious which SGC antenna you use and if the so to see Diamond K550 mount is strong enough to support antenna and spring? Thanks from PE1RNL
dolphinsdaydreams Hello Kees, The SGC is the 303 model. It screws into the threads on the mount as you can see. I did have to beef up the mount a bit though.... but, I'm no longer using that frame design set up. I completely rebuilt the manpack to a new box style manpack. There should be a link to a new video of the new setup on this video. Hope this helps and God bless and 73's.....Bob....N1TZU.
Love it do you have a video or link showing the measurements, I would love to go into my shop and build one of these. KD2MPI
Sorry Nikko, I do not. This was all built on the fly and in my head. Also, I don't have this frame any more. I built a new version which I also have a nother video of here ua-cam.com/video/419ago_Rtow/v-deo.html You may want to see this version before you start fabricating. Many blessings to you and yours.
Nice to meet you .
I am also using FT - 857.
I would like to use h / 250-U handset.
Please tell me the circuit diagram.
Hello OCTOPUS ARMS, The handset is actually off an old military telephone set. The plug has six pins. But I'm only using 5 pin for handset. You can do a google search and find pictures of the pin out for this handset. Check here as well- www.nf6x.net/2007/05/antrc-179-regency-net-hfssb-transmitterreceiver/ Then match up the wiring to your radio audio input. Hope this helps you out. Many blessings to you and yours.
I appreciate your quick advice.
I thought that looking at your MANPACK was very wonderful.
It is difficult to obtain parts of the US military in Japan, but I think I will make it.
I would like to have a conversation with you by radio waves.
P.S. I'm sorry for bad english.
What is the coil for?
Hello again,
Im working on a schematic that mirrors your headset/handset setup.. I am using a cobra with a 4 pin mic. If possible, I plan to mid the u94 with a cobra coil mic wire...as far as the h250u handset, where can I get a set of female male connections? Or what is the specific name and type so I can search!! Thanks Sir..
Hello again mastershimself, If you have the hand and headset that have the u-229/u connector .I believe you need the U-183/U 5 pin bulkhead connector. Search army surplus stores on line and you may find someone that has them. Have fun fabricating.
Hey Ham.R,
is this a short wave radio?
Hello friend, yes it is a short wave ham radio. The Yaesu FT-857d. It cover from 160 meter through the 70 center meter's band's. Great radio, because it is small and works very well for portable use. Many blessing's to you and yours. Robert.
What's on 2:04? It's a short I guess...
That view shows the switch that turns off the external speaker. A external antenna coaxial connection. And the fly fishing real which hold a counterpoise wire.
Ham R. looks and sounds really great!!!!
Thank you Aidar. I much appreciate the compliment. Have a blessed day and Yahuah(God) shine His face on you and your family. :-)
Thank you!)
Just so you know Aidar, I no longer have this design of manpack. I built a new one. Here is the link.- ua-cam.com/video/419ago_Rtow/v-deo.html
Ham slice there is someone on e bay that has these for sale
Its on Ebay
what kind of distortion makes voices sound like that?
Hello Con, that's what is called the SSB mode. ( Single side band mode ). When using a radio in the old AM mode, there is the fundamental frequency that your transmitter is making, say let's pick 3.885 mhz. Well, when the transmitter is switched to SSB mode. Your now only using either the upper half and or lower half of the transmission. So receiver tuning is critical to make the voice sound normal or natural.
Did you use a counterpoise? 73 de Mike
Michael Zehrfeld Hello Michael, In the video I didn't have the counterpoise deployed because I was just receiving. But, when I transmit the fishing reel mounted on the side has like a thin wire type rope that allows me to string out what is needed for any particular band. Thanks for viewing and God bless...73's...N1TZU....Bob.
***** Tnx for the information, Bob. Your ManPack looks so professional.....like an original military equipment - fantastic work!
73s and greetings from germany de Mike!
Very nice, very good job, can i ask for dimensions? On my desk is FT857D and this looks like good idea, how to use her. Thank you in advance, 73
Hello Peter, I no longer have this setup now. I built a new version. Check out the video of that here ua-cam.com/video/419ago_Rtow/v-deo.html
I love this open design much more than new version. But...no problem, i will try make a my own copy. :) THX 73
Very good Peter, I wish you well on your project. Many blessings to you and yours. 73's from N1TZU..Bob.
How did you wire/mod the H-250/U handset to the 857...
Hello Scorpio Taurus, If you look closely to the left of FT-857 there is a plate with the mating connector for the 250 hand set and also a 8 pin connector for head set use as well.. I have a short cat cable wired to both, and going into radio mic input and wire to speaker out put. You just need to figure out the corresponding connections hand and headset. I hope this helps. Robert.
There is a lot of interest on the 250 handset mod. Maybe you could do a vid on this subject. Easy to find on Ebay but don't know what connectors are needed and the wiring schematic for the 857.. Thanks for the reply.. Tony
does any buddy make these and sell them? I want one.
Whats the batterytime on this manpack?
+Cryptosporidium ....Hello friend, The battery time all depends on how you use your radio. TX time vs RX usage. If I'm just listening (RX) only the battery will run roughly 12 hours. On (TX) that time will vary on how much I TX and how much power I run. Hope this helps. Many blessings to you and yours...73's....Bob
+Ham R. it helps a little, if I buy the 857 I probably will buy two 10000 mAh LIPOs just to make sure I can get some radio time.
Cryptosporidium What I would recommend doing is, when running portable on battery, I try to run no more than 25 watts on transmit. The battery does quite well at that level. :-)
Cryptosporidium Have you watched the updated video of the latest manpack I built? I't explains the battery set up I use.
Yes, I saw that as well.. Looks really nice.
Are these available for purchase?
Hello Greg, The frame is all home brew. A description is above in show more. Thanks for watching. Bob.
Thank you for the reply. I do not have access to tools to make it. Would you consider building one for me I recognize the value of time. If not no worries but thanks again for you video.
Hello again Greg, It was quite a time consuming process. So could be quite costly. One other person in the comment section said he saw a bolt together frame on e-bay at Ham Radio station+Antenna Tuner backpack frame for YAESU FT-817 LDG Z11 LDG Z100 Check it out. That may be just what your looking for. Hope this helps friend. Bob.
Why does everyone sound like a robot?
It's part of what single side band sounds like if the radio is not tuned to the exact frequency the other person is transmitting on. I hope this helps to explain the reason for the robot sound.
This voice reminds me comms between ships in Battlestar Galactica series (recommended to watch!).
Under Fire conditions to many buttons make u confused..
It's not made for battle conditions. It's was made to just look like a military rig and made to pack out some where to operate. Thanks for the comment though. Many blessings Super8.
What is ,if it Raining ? hehehe.. Then this Crap goes down....Its only for Sunshie Weather or Indoor.. All other is building good...so my Codan 2110 or AEG 6861 is Much better ;)
10 amp hour lithium ion how much cost
Hello Alvaro, The battery in case with overheat circuit plus led level indicator plus smart charger was about $360.00 USD. I hope this is helpful. Many blessing friend. N1TZU Bob.
Ok my friend thanks 73 cordial
You have nice portable station
Thank so much. I had a lot of fun building it and have had many fun camping trips operating it as well. 73's
