I've been wanting to try to do the repeater with 2 baofengs. I'm glad you did a video on this! Can't wait to see how it works out for you. Thanks for sharing!
The duplex repeater is kind of strange. It doesn’t like when I power on one radio, or the other, out of sequence. For some reason, it keeps getting stuck in a loop, unless I power on the transmit radio first. The simplex repeater works perfectly. Zero problems, so far. I am wondering how the cold Ohio winter will affect it. Time will tell.
I want to do a portable simplex repeater. That I can set out quick for areas on my property that we have dark spots / places that we loose transmission. Plus boost our signal when I have family coming in a emergency. I’m able to reach the closest town now but when the leaves come on I will need a repeater or to. You know how Ohio’s terrain is
Have you considered a cross band duplex radio? The icom ID 5100 and the yaesu ft 400 are both capable of it. I use it for search and rescue. I leave the 5100 in the truck, where it can reach a repeater, and take a ht down into the woods. Works very well.
Thanks for the video. Do you think the company that makes the simplex repeater would have a cord that connects to a 20 watt Radioddity mobile GMRS radio? I see that the speaker-mic of that radio plugs into the radio through a RJ-45 connector. So maybe a cable with RJ45 connectors on each end would work?
www.argentdata.com/catalog/product_info.php?products_id=98 It looks like they have a variety of cables at the bottom of the website. Maybe there’s one that you’re looking for?
Power consumption is one issue, when duplexing, as it is 100% duty cycle, and during the hotter months, overheating could be a problem. The simplex version seams to be much more frustrating, as you have to wait for your talk back to be completed, before the other person can transmit their message, then you have to wait for their talk back, ect. Regardless, they both work very well.
@@PreppingOhio thankyou for the explanation. One last trouble , what about when u just use an audio 2.5mm to 3.5mm cable and connect to both with out using that box repeater box . What is that different and last does the power of the radios matter as to when it comes to transmitt or is it about ur height of ur antenna ?
@@SuAmigoElilegal I made a 2.5 to 3.5 mm adaptor cable one time and it worked, but there were some issues. I honestly cant remember what they were, but I do know there was something annoying. Regardless, it did work. As for power, and height, More is always better, unless you're using a magnetic loop. Stock antennas are usually not as good as any aftermarket antenna. Of course, building your own vertically polarized dipole is always better, for fm vhf. Throw a small amplifier on the transmit side and you'll really be able to get your signal out there.
I usually mount the receiver antenna higher when forced to use dual antennas... On most of our larger sites using combiners / multicouplers, we generally do the same. It’s so much less $ and aggravation AND tower loading ... it generally pays to go the route of a duplexer. If you are near NYC (suburban NJ actually) and need a duplexer tuned, reach out to me and, IF YOU CAN PROVE you didn’t vote DemonCrat in 2020, it’s NO Charge! 😀 Great channel Ohio.. Thanks!
Get yourself a small “mobile” style (notch type) UHF duplexer. The small ones can easily handle 25 watts continuous / 50 watts intermittently. Using the GMRS frequency pairs, as is typical for public-safety, IG /“business band” and most ham repeaters, you’ll have a 5 MHz. split between the TX AND RX frequencies. The input (RX) of the duplex repeater is spaced 5Mhz HIGHER than the output (TX) of the repeater. (example: 462.6500 would be the transmit freq and 467.6500 would be the receive freq. The duplexer permits you to operate in full duplex mode utilizing a single antenna for both transmit AND receive. The antenna is connected to one port of the duplexer, the transmitter connected to the “high” side and the receiver connected to the “low” side. The duplexer MUST be tuned to the precise frequencies it will be operating on. The tuning MUST be done with somewhat specialized hardware.... a vector network analyzer or a spectrum analyzer with integrated tracking generator will be most definitely required to accomplish this task. (local radio shop will usually do it for $50-100 bucks to cover their labor... or, alternatively, check with a local “ham” radio operator or amateur radio club. You can sometimes find someone to handle this task for you for a case of beer or naked photos of Hillary Clinton AND $20,000 TO COVER THE MENTAL DAMAGE INFLICTED BY THE PHOTOS. 😷😆🤣 The type of duplexer I described above, the “mobile” type, can be had for anywhere from $75 to $400 (depending on manufacturer, power rating, etc... AND, MIGHT COME TUNED!) The principle of operation is fairly simple. The duplexer works by “notching out” the transmit frequency from the receive side and “notching out” the receive frequency from the transmit side. This permits simultaneous operation of transmit AND receive without interference on either device. If you are located near NYC & surrounding metro area, drop me a note if you need any assistance. I’d be more than happy to assist you with the tuning side of things. I will DEFINITELY be opting for the FIRST payment option!!!!!! 🥴🤣. Actually, a simple cup of coffee and a donut will suffice. One other note. A simplex repeater might be a good option if you are using this for emergencies and do not know if all family members / friends will be able to constantly monitor a radio. Users can drop a message in “storage mailboxes” IF the repeater controller is equipped with storage. I have installed a few of the Argent Data devices many years ago. The audio quality was not too bad. The RadioTone sounds like crap for sure and the Surecom is supposedly equivalent to the aArgent. Also... if locating a full duplex repeater in a “high RF” area, such as a radio tower site with other repeaters operating in the same band as you are (ex: both operating UHF repeaters), or the site is very densely packed with radio gear, definitely consider purchasing a BpBr (band pass / band reject) type duplexer. Simply explained- the duplexer .. actually... please Google it. My fingers are tired from iPad screen typing 😉😀.

RG400 is easy to work with (similar in size to RG58, but has a Teflon dielectric and outer jacket and is usually plenum rated) Do NOT use RG400 for long runs due to signal attenuation.

@@PreppingOhio what is the different using this box vs using a audio canle 2.5mm to 3.5mm radio to radio or just simplex radio to radio . If the antenna is not in a good place none of these methods will work

Won’t work right, you’ll need a duplexer.
This has been on my list of things to do, thanks for the reminder.
Good info Thanks from western PA
How many miles can transmit this you try to check it already in the simplex repeater great blog
Can you show the UV-5R programming sequence to get your mobile to hit the repeater?
this is sick, can’t wait for the videos
Next video will be in a day or two. Thanks for the positive support!
What cable are using to go from K1 to rj45 or rj12

@@PreppingOhio Thank you!
@@PreppingOhio the other way to do it is to connect the repeater to an HT, then to a linear amplifier, then out to the antenna.
VA3DLO HAM OPP HEAR ... wear do i get that repeater Symplex box thanks
Could you describe the duplex repeater you have there? Thanks.
HOW TO BUY THAT ?
What is the different using this simplex repeater vs a duplex repeater box where u need 2 radios. Is there a different on performance

Witch antenna needs to be the highest when u don't have the douplxer . The Rx or Tx antenna
They both should be around the same elevation. I like to keep them separated about two wavelengths, or more.
I usually mount the receiver antenna higher when forced to use dual antennas...

Can this work with 2 baofeng 8watt
Yes. This can actually work with any radio, if you can make or buy a connector. Of course, the legality of it, should be checked beforehand. 🙂

This is never a repeater! At least is a crossband repeater!!
Well, it is a repeater. And no, it’s not cross band.
Prepping Ohio please tell me what is the name of the duplex repeater.
@@PreppingOhio You could make this cross band by changing offsets for transmitting.
