In this video, I show you how anyone can build a very simple simplex repeater. Using just a single handheld radio and a recording "parrot" repeater controller. You can build this yourself for as little as $100 including the cost of a dedicated handheld radio. It will work for both GMRS/HAM and VHF or UHF (2m/70cm bands) It is incredibly easy to do and works extremely well. I build, I test, and show the results. This is intended to show what is possible with just stuff laying around the house. Rubber bands, twine, and a little radio gear.

DIdid not hear you ID on the radio at all. Charlie

@Commodium 2 месяца назад

*Yes and that's intentional.* (Muted out) I ID on the radio, not for RU-vid. Being a super sexy RU-vid star, the last thing I need is to be stalked at home. Even though my GMRS info is secured with GMRSRegistry.com, My business license is not and I don't need some enterprising person cross-referencing my FRN only to show-up to my home and suddenly they receive an "accelerated case of lead poisoning".

@indridcold8433 2 месяца назад

I need to know where to get the counterpoise and the tactical elastic restraint.

@Commodium 2 месяца назад

LOL! Another viewer mentioned "Ranger-Bands" which are damn fine EDPM rubberbands. The counterpoise I make from 10ga *silver tinned* silicone jacketed wire. Seal and heat shrink the far end. The radio connection is a tinned copper spade connector that's heat-shrinked after crimping. It's then optionally painted with a camo pattern. The length should be about 20.375" from the tip of the spade to end of the wire. *I do sell them as well.* But honestly, they can be made with any wire. It does have to be expensive silver tinned 10ga. I try to use the absolute best when making radio accessories/antennas when possible.

@sweetbushstudiochannel4606 Месяц назад

What did you use for the counterpoise (counterbalance)?

@Commodium Месяц назад

I use 10ga. stranded silver tinned wire. Heat-shrink cap on one end, spade connector at the other. Lengths vary, but 19-1/2" to 21-1/4" will work best.

@kchedville Месяц назад

Will this work with the Talkpod A36SE GMRS Two Way Radio and the other Baofeng GMRS Radios?

@Commodium Месяц назад

Yes as shown in the video it will work with any radio with the kenwood “two prong” style cable. Surecom has other cables compatible with other radios. And if all else fails, you can build your own cable if you know the “pinout” for the radio. For custom cables you would need to identify the mic+, speaker+, ground, and PTT. With those four pins properly identified a custom cable and be made for any radio that uses a “low” PTT signal. For more advanced users, a cable with a transistor, relay, or even better and opticoupler can be made for radios that use a “high” PTT signal. But if you have those skills, you would most likely be using a more advanced repeater controller in the first place.

It works as well as removing a phillips screw with an undersized flat-head. Yes it technically works, but def the wrong tool for the job. But it can work, just not well.

@Bootyhunter1971 Месяц назад

Not with these cheap chines radios. They desense each other something awful. The radios are great for the price but their intermod rejection is nonexistent.

@redsengineering 2 месяца назад

What is the green cable attached to the radio?

@Commodium 2 месяца назад

That is a small length of 10ga wire. It acts as a counterpoise or ground plane for the antenna. Handhelds are designed to use you holding them as part of the antenna system. Being hoisted up into a tree without an operator, the antenna needs a counter-balance or ground plane to operate as efficiently as possible. The abbree antenna I used in the video requires it on lower VHF 2m but not on the UHF 70cm. If you have watch the "How far can you talk" video I have, it will go a little more in-depth on counterpoises. Thanks!

@shawnstimson239 2 месяца назад

I second this question. What did you use to make, or otherwise source your counterbalance/counterpoise?

Hence the cheapest repeater you can build. But the 5RM isn't a bad little handheld. It works and for most people that's enough. I have gotten 42 miles with stock antenna into a repeater at about 200ft elevation. Now granted it was scratchy audio, but still usable.

@stewartjas68 2 месяца назад

Awesome stuff. Questions: 1) how is the surefire powered when up in the tree? does the Kenwood cable power the surefire? and 2) does the ptt on the baofeng need to be depressed while up in the tree while hooked up to the surefire?

@Commodium 2 месяца назад

All great questions! #1 the repeater controller has in internal battery. It charges via a USB cable. Even though it's only 900ma, it will last a bit longer than the handheld radio. #2 As far as the PTT control goes, the controller itself will initiate the PTT via the kenwood style cable. So no need for VOX. Basically connect it together via the cable. Setup any CTCSS tones you want to use (always a good idea for a repeater) then throw it in a tree or up on a pole. Dead Easy!

@@Commodium bad the heck ass...i'm gonna give this a test run this weekend at the lake. i knew you mentioned the internal battery; just was unsure if that was what was relied on for the video. possibly, a USB battery brick could be integrated for longer term but this is fun. thanks.

@Commodium 2 месяца назад

Food for thought... If you have a two-port USB Brick (or splitter), and the radio has a USB-C charging port (5RM among others) you could use the power brick to extend the battery life of both the repeater controller and radio for a few more days of use. @@stewartjas68

@@Commodium You definitely want a tone on the repeater receive radio. I had a microwave tower start tripping the radio on and off and by the time I got back to the car. It had fried the SureCom SR-112. This will work with FRS radios. Amazing when local kids start hearing themselves on the radio. They cleanup their act quickly.

@sandmanxo 2 месяца назад

Not a bad quick setup, but with the repeater itself being $60 I think I'd be better off on gmrs just linking a couple of cheap mobile units. I can see some good use though for 2m to test range from my property to my mobile unit. I still may get one for that and just park it on gmrs for the rest of my family most of the time. Add in the 30watt solar panel I got and a cheap buck converter to keep everything charged it hopefully would run for a year or so before something in the cheap chinese bundle broke.

@Commodium 2 месяца назад

Linking a couple mobiles for GMRS works nicely. If doing an in-band repeater with them, it makes a huge difference having a duplexer with filters. Those get real pricey real fast for anything above 25watts. The transmit radio can swamp-out and de-sense the receive radio. Even with spacing the antenna. Sure it works without one, but missing a good chunk of additional range. And if you already have the mobiles, have the skills, duplexer be damned, do whatever suits your needs. That's what gets me frustrated with "radio experts" always want to be nay-sayers. And eventually these surecom repeaters fail. I have found it's always the batteries that crap out. But they are easily replaced with more cheap chinese junk and your off to the races again. Thanks so much for watching and sharing your thoughts!

@sandmanxo 2 месяца назад

@@Commodium Thanks for the advice. I don't have a gmrs mobile and will do some research. I just want to put something up cheap on the other side of my property(acreage) where it's 50' higher elevation than the house. I eventually plan to put up a 40' tower over there(no tall trees) but will just use a pole for now. 25 watts of output is fine as the difference between that and 50 is pretty negligible. As far as interfere, I've seen entire hf bands wiped out by a 100 watt signal a mile away so no surprise and will have to get some decent filters. What I'd really like to do is use a Raspberry Pi Zero with rtl-sdr for receive then link a mobile for transmit, but I'd have to get some time to put it together. The surecom would just be a quick solution and hacking some new batteries together wouldn't be a problem. Agreed with the experts, better to have something up than spending thousands to try and do it commercial grade so I can talk to a couple of extra unappreciative crotchety old hams 2 counties away in fm. I can do that on 20, 40 and 80m for a lot cheaper lol

brasuela? oh my dear,, it is right there ,, south america,, right next to uruguay ,, betwin Atlantic Ocean and Peru...

LOL hahahah,, You also can call it Brasuba (Brasil + cuba) , or Brasambique (brasil+moçambique) ,, you can call it simply of Communist country, the bigger here in south america. meanwhile, our president is sending millions of dollars to communist countries like, cuba, moçambiqueetc, claiming it's humanitarian aid, while our people here suffer in poverty, with never-ending construction projects that are merely a means of embezzling public funds... that's why I now refer to this country as "Brasuela," as it has become a dictatorial country just like its neighbor, Venezuela. Our president is incompetent, and the dictator here is a minister of the Supreme Federal Court (STF); he's the one pulling the strings. On January 8, 2023, he arrested around 300 people and sentenced them to 17 years in prison simply for protesting. Over 200 people, including children and the elderly, are still in prison to this day! Doesn't the media outside show this? I'm appalled!😵‍💫
