I never even looked at the Tech test and passed on the first try. I am taking my General soon and was able to pass the test without studying.
Here is a good resource to prep for the Amateur Tech test https://www.eham.net/exams/

For using it for amatuer use?
I was mistaken, I thought you mentioned using the $24 dollar radio on GMRS.

Rick,
Don't expect to many people to admit to breaking the law on an internet forum. Here is my thoughts, the Baofeng and its many knock offs are junk. The radios sound like crap, cause adjacent channel interference and preform poorly in the real world. Now I know all the Baofeng fans will come in out in full force to defend this junk and I will never know why. Even the beloved Btec GMRSV1 fails to maintain its frequency stability if you TX long enough to exceed the 5% duty cycle. You get what you pay for with radio gear, if you buy a 20 dollar radio its going to work like a 20 dollar radio. I have several users on my repeaters that use them and to be honest I plan to start revoking permission because of the poor audio and signal quality.

I ran mine down the center without issue. The UHF and CB will not cause any issues.

I am still not sure why these posts keep appearing in GMRS groups. It is and has been legal for business to use FRS channels... People dont read the rules but claim to know them all the time. I see so much disinformation on the internet regarding the part 95 rules and some of the GMRS groups on facebook are the worst. If you try to correct the admins they block you for pointing out the truth...

Food for thought.
I have done long range wifi with a set of $3000 ubiquity air fiber dual dish +45db gain set up, 41 miles is as far as I got. Internet is the best option over a 100 miles. You can't dispute the science of a link this long, telcos used huge feed horns 20' wide, 200' in the air and 6" wave guide with over a million in infrastructure to build and maintain a single microwave links 100 miles. The FCC won't licence a path that long. I link several sites together using cellular internet, at 15 bucks a site it will take years to over come the cost of a WIFI or microwave link. Don't waste your money, trust the science, 160 mile link cost effectively is a total pipe dream..... If you do the math the aiming of a link 160 miles apart would need to have an accuracy of .005 of an inch or roughly the width of a human hair, good luck maintaining that with wind and interference along the path.

And nothing that the OP suggested would change any of that. Adding an exception for already licensed HAMs to use their already existing and perfectly capable gear wouldn't change anything that's happening in GMRS currently for non HAM types using it. Just means that we would have to spend less money on redundant equipment to stay within the letter of the law.
Though I'm sure there's already plenty of combo HAM/GMRS guys running around with Amateur gear programmed for GMRS use.........
I might add that GMRS has tolerances as far as frequency that are far lower then most HAM gear. With GMRS being smack in the middle of the part 90 portion of the band it is important to maintain some type of standard as to not cause interference to the adjacent service. Requiring a type accepted and certified transmitter is the best way to do this. Posted this again just to be clear, I am a HAM but use part 90 gear for UHF and VHF. If the chart below posts you will see that typical HAM banded gear can allow error rates as high as 10ppm, With GMRS being a wide band service in the middle of the narrow banded part part 90 service its important to use certified transmitters. I have had plenty of HAM gear on my Aeroflex 2975, very little would pass 2.5ppm tolerance.

I want to say hello to everybody and let you know that I will spend more time looking around than posting. Former Cable TV Tech in the 70's, ham radio in the early 90's (big into APRS) and now retired to the corn fields of NW Illinois. I know just enough about antennas, cable and electronics to make me dangerous. Getting into GMRS so my wife can keep track of me without using the phone. (Anybody remember when cell phone service was cheaper than a landline phone)
Hello and welcome, not sure about your location, I have a wide area repeater in IL, follow the link in my signature below for more details.

GMRS is for families. No test, covers your whole family. No tinkering, grab a pre programmed radio and go.
The downside is that the FCC limits the equipment that can be used to prevent people from plugging numbers into a radio and causing interference.
There would be a lot more confusing regulations to follow if the FCC started putting all kinds of equipment exceptions for various other services, which then creates more problems than it was trying to solve for a family jist grabbing a set of radios and going.
My wife and kids are not interested in Amateur radio. This allows us all to communicate with few issu

I recently looked at the FCC part notes for the GMRS-V1. At the time of this post, I was unable to access the FCC OET Authorization Search page. But, I was able to access another page with information on this radio (https://fccid.io/2AGND-GMRS-V1).
I see that this radio uses the 15K5F3E emission rather than the traditional 16K0F3E or legacy 20K0F3E on the 462 MHz frequencies. This radio also uses the same 15K5F3E emission on the 467 MHz frequencies rather than the 11K0F3E emission.
And, take note of the power output on these frequencies.
Quietly moving us to narrow band....

I Regularly talk 25 miles simplex on my GMRS base, I also use it while traveling in groups 10 to 15 miles simplex. Quality equipment, thru roof nmo mount with a 1/4 wave antenna.
As far as narrow band equipment on a wide band repeater, the narrow band radios clip the audio real bad and the wide band people can hardly hear them.
Its been debated and answered in detail here and every other GMRS forum i belong to, as far as a base stations power limits, it is 50W. You are free to call or email the FCC as I an several 100 other people have, you will also be told 50W.
If you got rid of the narrow band radios and went to full legal power commercial part 90 wide band mobiles and portables you would see a huge improvement.
With your base units don't skimp on the antennas or coax as this is the best place to see gains on UHF.

Welcome to MyGMRS! Should you not find the info you seek just ask, lots of experienced radio heads lurking around here!

Can we converse on GMRS via the internet like Echolink for Hams?
You are asking the same question that this entire topic is about, I have also provided an answer to your question and here it is again. Echolink is HAM, this is GMRS. Most of the HAM linking systems are based on Asterisk using the Allstar network. Asterisk is the same system that is being used to link GMRS repeaters using the network here at MyGMRS or one of the other GMRS networks that has been set up. Some allow simplex nodes some don't. The MyGMRS network is repeaters as they are more useful. I would suggest you go back an read whats already been posted as your question has been answered already. As well this forum has a topic dedicated to just this... Below is the link you could have found by reading my other post or simply using the forums search box at the top of the page. I don't mind helping or answering anybody's questions so long as you first attempt to find the information on your own. Answering the same questions over and over because people don't want to take the time to look is annoying and a big turnoff.

Hi all,
Maybe im stupid, Ive been told that before, but I don't see a problem. GMRS is a radio service for people that want a family or a friendly radio service. People that just want to pick up a mike and talk.
Why does everyone want to make this into something it is not and never will be.
If you need something more than what it is, get an amature license. I dont have an amature license and Im happy with it.
Wow, you got me ranting. SORRY.
I don't think linking GMRS repeaters is trying to make GMRS something it is not and will never be. We have been linking machines for a few years now and its been great. It has expanded the area of coverage from 30 miles to 3 states with the ability to connect to several other states. If you have friends and family in a different city or state you could still enjoy using GMRS with them by simply linking a repeater in each area together. The owner of this site has a nice system in place, check this out https://link.mygmrs.com/map

I've spoken to Corey, who is in touch with the FCC field office. It is questionable as to the legality of re-transmitting an EAS message over GMRS. EAS messages when pertaining to serious or life threatening storms, tornado's, and even certain civil emergencys (amber alert for example) could be allowed under FCC rules which is what I think Taco is asking about. We have yet to hear back as to what the formal answer is.
There are systems that take the EAS message and translates it, simply transmitting a short tone followed by "Thunderstorm" or "Tornado" as well as the county affected. Such a transmission would be 100% legal as it does not rebroadcast any part of the EAS message or voice traffic from the weather station to my knowledge, however it would require the repeater to also identify itself.
Not this Corey!
Now that you have my attention you will get my Opinion.
WX over GMRS, annoying to say the least. We have a garage repeater in my area that tells as the time, date, humidity, temp, ID and website every 30 min. As soon as a SAME WX alert comes thru it breaks in with the NWS for 2 full rotations of the message. To make matters worse it adds it to the end of the gibberish info it sends out every 30 min. Under a SAME alert this thing will spit out 5 min of worthless channel blocking information to nobody every 30 min. During this time the repeater is rendered useless and could hinder real emergency communications.
In my opinion this is not what GMRS is intended for, if you have a need to monitor a WX radio buy a weather radio and leave GMRS out of it. Last thing we need on our very limited amount of spectrum is GMRS repeaters broadcasting something that is already broadcast to most of our population.

Repeater Finder is a project Rich has been working on, its data comes from MyGMRS.

Funny no matter what Forum linking comes up in it always starts a POTS debate, one that's been beat to death. Nothing I do is over POTS, in fact the Asterisk server is sitting on optical fiber and the nodes on dedicated point to point connections or cable. As an IT professional of 25 years I can assure you DSL is not POTS. Unless you are doing an auto patch to a POTS line or using dial up for your internet chances are your internet has been been off the last mile for years.

Greetings y'all. I have finally decided to get an adapter to use my mobile as a base station. Thus, I want to introduce myself as a complete GMRS newbie that is ready to start talking. I am in the North DFW area of Texas and if any of you are local, please let me know. Looking forward to meeting y'all and chatting!

I don't know where the FCC is on enforcement but here in Racine Wisconsin the WI DOJ has been knocking on doors looking for the people that have been connecting radios to the statewide P25 trunking system known as WISCOM. I know 2 ex law enforcement offices that both got visits yesterday. With the visits came lots of questions about one person... All I have to say is play stupid games win stupid prizes, FCC won't investigate so here comes the DOJ. When caught these guys will wish it was the FCC because the DOJ will issue you and anal probing the likes of an alien abduction....
