I thought I was gonna have to spend an hour figuring all this stuff out. After watching this, I think Im all good. Thank you!
Thanks, I’m so glad it helped.
did you try and read the book it will tell you everything.
Great information. Thank you!
Very clear information
with two radios set on the same code thay will only talk to each other on one else
but eveyone that find's you will only hear you
only privecy codes do is lock two radios to gether sothay only seack each other
and no other radio BUT we can still hear you just the same
Simple answer = NO, PL / DPL codes only filter off traffic and interference that is not intended for you.
any one can hear you thay cant talk to you with out your code
all the privet codes is lock your two radio so you can talk only to each other
if someone was channel hopping thay would only hear you and add there two cents.
it is nothing than sail hip LIKE are radio will go 38 miles but thay wont tell you how
more hipe and thay don't know anything about them so I gave up
the privecy code does let anyone out side you group talk to you thay still hear you
How did you get to channel 128? Some people talk about it but no one ever shows how to do it
channel 128 is really channel 12 and 8 is the security code number
there are two sets of numbers like I said channel 12 security code is 80.
ok so here is my question, how do you make it to where no body can here you? so lets say i go on a hiking trip with 4 people all with radios, and we want no one to here our chatter? how would you do this.
So the only way to do this is through encryption, but encrypted communications are banned by the FCC on FRS/GMRS/HAM frequencies. Depending on how far apart you plan on being from your group, there are devices made by GoTenna or Bear Tooth which allow you to text, talk and create a mesh network which is much harder to listen to.
The other option is to get retired public safety radios, but that’s a huge undertaking unless you know somebody who is capable of programming those types of radios.
Get a commercial frequency license
Learn a new language!
sorry that won't happen thay can still hear you just not interupt you that's all
sorry only police radios can do that your code in to radios will talk to each other only but any one scanning the channels and hear's you can only hear you
not talk to you
Ahahaha @ falling to sleep! Classic.
Are the t800s any good? I was thinking of using the text feature on a cruise? Will also pick up the rockies.
Great question, and while I also have a set of T800’s, I don’t have a lot of experience with them. As a rule, I’ve always been impressed with Motorola public safety radio, but found their programming to be very unfriendly. The same is true in my opinion for the T800. I attempted to set up two radios to share location and text abilities on a trip about a year ago. The friend I was working with gave up out of frustration so we scrapped the idea. I am sure lots of people have used them successfully, but I have not. Have you looked at the GoTenna system? I use the GoTenna Pro X public safety version, and have really enjoyed them. If you have three or more devices they create a mesh network, extending your range. Still not super simple, but purpose built for sharing location and text ability.
Just to be clear, I suggest you consider the GoTenna Mesh, not the Pro.
@@AdventureCruiser thanks. After I watched your video. I saw the gotenna mesh system. I think I will go with the Gotenna and the Rocky Talkies.
Oh very cool, please let me know how you like them. Safe travels.
The T800's are capped around 1watt on 1-7+15-22.
that line is used buy the company selling the radio for hip my raio's where built with out them as we don't need them as we run G M R S side of radio's
Hey question so connected my rocky talkie to retrevis rb19 and i can hear everything but can't talk back ,can you help ?
If you can hear on the rocky talkie but not on the retrevis that means that the PL, CT, DCS codes don’t match. Try setting them to zero on both radios first. Then go to the manuals for each and match the values of the code numbers, not just the numbers. I hope this helps.
@@AdventureCruiser how to set them to zero cause i have no idea
@@mgkmn1 I can’t tell you how to do it on your other radio, but from the factory Rocky Talkies have the right one set to 0 for the first 22 channels. Check out my other video titled “can I use my rocky talkie to talk with other radios?” It covers the how to.
your answer is right you match the codes the same then it will work
GET OUT THE BOOK AND READ IT IT WILL TELL YOU EVERYTHING
GRASS HOPPER.
I didnt realize encryption was an actual thing on these though. What sort of radio/setting allows for actual encryption?
DMR, and usually AES on analog.
A POLICE RADIO IS ENCRYPTION not these.
and the police have a fue encryption channel's so the news stations don't
get the hole story that is why
Well then, privacy tones makes no sense to me. If it stops me from hearing other radio transmissions, then what if there's a bear on the trail up ahead and a third party transmits this information in the open, I'll never hear it, and I'll be ignorant of the danger that lies ahead and like all those people who are dropping dead because they took the axe-ins, when someone find my dead body they're gonna say, "Lemme guess, he had on privacy tones, right?"
If you are interested in hearing everything people have to say, you should also engage the scan function and it will sweep over the different channels to hear.
Just imagine though, if there are 100 people talking at once, nobody can understand that, this is just a way to cut though if there is a ton of folks talking
I agree. Privacy codes are dumb. You'd think it would be the opposite, making your conversation private. Totally useless in my opinion. But I don't mind if I hear some chatter.
your right may be a good I dea to leave open by the way you need to be close a nuff to talk range on all frs radios is
two miles then everyone can talk
IF that happens you better hope everyone is less than a mile apart
or there out of range
Pre set tones and pre set channels
Thanks
All it does it suppress noise
you are on a channel with code I scan the channels and fine you I will hear you but I don't have your
I am out that is what it does
SORRY only the polce can do that all the codes do is let the radio's talk to only each other you cant but in becouse you did not get the code at breffing this morning
BUT YOU CAN HEAR THEM only P.S. why are we three years in the past
Then why is it called privacy then. Make no sense
a ediet printed the box and did not understand any thing ok thay put 35 miles on package that on G M R S range
selling point from corpert thay don't know eather I solved that problum I bought a radio that does not have all that nonsense we in the off road world don't
need it you cant use it on G M R S anyway and where fine running 45 watt radios.
SAILES HIPE that is it this will go 38 miles and nothing to tell you how to do it
H I P that's all I do this every day surf u tub every day thay don't read he book
and wing it then I clean up there mistake
Just call it a filter.
That's a good thought, but still not completely accurate. A filter implies that it ONLY lets through what is supposed to get through. Once a privacy tone unlocks the squelch of a radio, it will let everything on that frequency through, regardless of the privacy tones being used. So it's really only a filter to initially open the squelch, but once it's open, its open.
@@AdventureCruiser not true. Remember these are shared channels with higher powered GMRS radios. If you are talking to another FRS radio and he is somewhat distant, and you are using a privacy squelch tone, a much stronger GMRS signal could key up on the same channel with another privacy code or even no privacy code and could completely override your other stations transmission. Since the overriding signal will mute your squelch you will suddenly hear nothing. A far better option is for everyone, including GMRS stations to NOT use privacy codes. You could then hear that your other station is getting "walked on" by the strong station and communicate with the interfering GMRS station. You could then break in and request your other party could move to a clearer channel. Additionally you might encounter electrical interference that can trash your ability to hear. With privacy codes you don't hear the interference because it would silence the speaker. With no privacy code you could hear the interference and search for a quieter channel. A good way to operate is with privacy codes off. Although filtering out the audio from undesired transmissions sounds nice, you could be muted by an stronger source of interference and NOT even be aware it is there. So in essence you are deaf AND unaware. A far better option is to use no codes and be aware. If a channel is busy, just break in and move to a quiet channel. As a rule of thumb, channels 8-14 are your best bet. GMRS radios (possible sources of interference) are limited to only half a watt on those channels. On channels 1-7 they are allowed 5 watts, and on channels 15-22 GMRS are allowed a full 50 watts. At that power level they might crush your low powered FRS signals. At least channels 8-14 levels the playing field with equal low power restrictions. Yes it is boring, but detecting and evading possible sources of interference is critical to maintaining effective radio communications. That said, I think the privacy codes are very misleading to every day consumers and are best not to be used.
@K9WLW Radio so, which part are you saying isn’t true? To some extent I think see what you’re saying about a more powerful and different PL closing the squelch of an FRS radio, but I’ve only seen that technology in public safety radios where they call it “reverse PL” where a PL or CTCSS/Dcs can not only open the squelch but more importantly, close it at the end of a transmission to presumably decrease the burst of static as your radio realizes it is no longer receiving a signal. I think I understand what you’re driving at, but in my experience I’ve had radios let in any transmission once the PL tone has opened the “door”. As a matter of fact, I experienced this today while in Moab and both transmissions were a little garbled from overlayed modulation, though the closer (I.e. more powerful station) prevailed, so I don’t really understand your issue with my summary. I agree that it would be most polite to not use a code, but my intent isn’t to rewrite the FCC rules or guidelines but rather explain what things do, and the biggest point I wanted to make is that Privacy Tones (or PL) really aren’t private. Sorry if we disagree on some of the details, but I think we can agree that the main point is that it isn’t private.
the company's never thought about that be course thay don't know radio's
them self's and thay don't want to here is a quote from another channel
a guy from buy two radios would not tell a guy how to change battery's
there answer this would run over and make this to long called the co up and called the guy a jerk.
Your analogy is more confusing than it is helpful. Good try though.
LOL i was about to comment the same thing 😂
I have a G M R S license that is why I know and your lerning .
PRIVACY TONE ISN'T PRIVATE. IT'S USELESS. DON'T USE IT
Not entirely true. It’s absolutely not private, it doesn’t keep others from hearing you, but it does give you privacy in that it blocks much of the unwanted interference and conversations.
you are right jest leave it off that's a stuped thing thay put in to confuse every one my radios dont have that
becouse my radios are for off and I am on a repeter my base is 45 watts output
