I realize this comment is four years after your posting, but the new Part 95 GMRS regulations (Sept. 28, 2017) do not prohibit the use of a "simplex repeater". All that is required is that each radio used be Part 95 certified and announce your FCC call-sign at the end of your transmission. If one gets hung up on the definition of a "repeater" then call the use of a simplex repeater a "store and forward base station". The BTECH GMRS V1 radio is Part 95 certified and by pressing the # key will reverse the input/output frequencies and privacy codes, that and it's DTMF abilities allows for the efficient use of the Argent Simplex Repeater. For those needing only a short term (weekend) repeater, I simply put the radio and Argent box in a waterproof kayak bag and with some 1/4 inch rope haul it up in a tree. Thanks for the most informative videos on the use and setting up of radios and "repeaters".
Excellent. I saw these videos many years ago, but only recently had the money to get this simplex repeater. It will be used to tie 4 small mountain communities together using common GMRS transceivers. Thanks for your video. Good stuff.
the portable simpelx repeater that you built is great and your talks are wonderful i watch your videos for info as i im working on getting my amature license thank you for your knowledge
You should have said something about the cable between the radio and the recorder/controller needing a ferrite core, to strip off RF energy before it hits the audio recorder/repeater controller. Thanks for the video! Jimmy, ARRL TS, WX9DX
GG - Great video! Way more comprehensive than the videos I did on this unit. One day I would like to try floating one of these units with balloons to see what range could be achieved.
420.000 MHZ to 450.000 is only for licensed ham radio operators only. In the band plan it may say experimental but is for license amateurs only! This radio frequency 420 to 450 spectrum is not for anyone in the general public to use. Unless you have a valid ham radio license of technician class or higher.
I remember watching this video earlier, and what you said about DCS codes. 7:10 I did my own testing on this, and it doesn't matter whether you use inverted or normal DCS. I programmed a radio with a random inverted code and tried to pick it up with a scanner. Of course, the scanner decoded the inverted tone in its "normal" equivalency. When I entered the normal value that the scanner got me into another radio and tried to communicate with the inverted radio, it came through just fine. So I think inverting your DCS codes won't be of too much help.
@@Joebanker80 Yes. DCS/CTCSS codes will only prevent interference from co-channel users. Listeners and malicious parties still have access. What you would need is a scramble feature or digital radio with privacy enabled. (Doesn't matter which: P25, DMR, NXDN...) Swap that with the Baofeng/TYT and use a non-GMRS frequency (SHTF scenario, right?) and you're all set.
Thanks for the correction, I have not paid much attention to those setting except for D wait. I mainly use the wouxun now and western radios, so I forget some of the functions. Either way, all those features are turned off so as to not make the radio work any harder.
a few of the things are wrong there, apro is the compander or scrambler which can be enabled from that option; dw is when listening to fm radio, it watches the radio channel for activity at the same time as listening to broadcast radio; d wait is what you that dw does, where it watches both channels on the top and bottom
thanks for the blog sir ..im a gmrs guy I have a gmrs license iwanted to creat one but don't know how how much do I need to spend for gmrs simplex repleater i have a btech gmrs v1 and also a retevis 76p gmrs radios ..pls help me for this thank you I'm from northern California sanfracisco located thanks
So it has been a couple years... any hindsight? IE would you have went with a diff product or done anything different? I'm looking to upgrade my field repeater here soon to something that is more versatile.
a In "peace time"s long as you're not inferring with my amateur radio operations I don't care how other amateur radio operators use their stations. if things go to hell I'm going to have more important things to worry about. As I and others read the rules only a full duplex repeater is permitted automatic control. Interesting idea to stay hidden on RF.
+bob hope Just saw that. My site is small potatoes, not worth the effort. No repeater site is safe for that matter. I don't ever solely rely on one system, single point of failure in any tactics is a recipe for disaster. That was interesting what you did though. the vid had no audio, but I got the idea. Thanks for watching.
hey i have code to break the password on those and keep rebooting the repeater thus downing your comms and forcing you to expose your site might want to rethink your comms

The band plan you were talking about is not for everyone to use like you are saying. UNLESS YOU HAVE A HAM RADIO LICENSE
I always learn so much watching your videos

No reply from him ... I believe you’re spot on.

Don't worry, I found out that DCS is legal on FRS and GMRS so you can use it without any hesitation

Could you hook up a btech amplifier to this and get more range
an arduino and relay shield may help with stability by rebooting every now and then it did with my wifi repeater
for even more security, I guess you could turn on the scrambler, or is that not allowed on GMRS?
Good video Thanks for sharing

What is the different using this simplex repeater vs a duplex repeater box where u need 2 radios. Is there a different on performance

yea had sound card issue
posted a video with code running under guerillacomm simplex repeater

runs on linux android and windows
Thanks for your videos. I would post more videos but I can't put up with the idiot comments that some make.
security risk
"★★★★★"

we don't like roger beeps . its more of a N.A.S.A thing . when talking to a space shuttle or the space station .
