Depending on where you are going, specific types of radios and two-way communication methods are illegal. Im sure the company is trying to avoid any criminal liability. Not to mention, imagine how bad the radio waves would be crowded a d how much RFI would be causing issues on a big ship with 8,000-10,000 people, all trying to usetheir radios at the same time.

100% agree with the above post. Great advice. GMRS radio is not intended for what you are trying to accomplish. Satellite communications is the best option for what you are planning.

I built a portable repeater system for use in amateur radio, using a Yaesu repeater. I stuffed it in a Gator Case. It is 100% self_contained for use on UHF. You need to add an external duplexer for VHF. My biggest problem is that the repeater itself is so large that I couldn't find a waterproof case that was at a price point I could live with. I do like that setup in the tool boxes. I would slap a push/pull fan system on it for pull-through cooling and you could drop it anywhere, regardless of weather. Right now, I deploy a 4-season shelter when I want to deploy it, or I run it out of the Jeep, if the weather is really bad and I don't need to be mobile while the repeater is in operation. I wouldn't worry about power so much, and focus on antenna hight. I have used a drone to drop ropes in trees and hoisted the vertical antenna well over 100 feet in the air. This gets you way better coverage than an antenna on a 20'-30' mast. This gets a little tricky if you are in a cityscape. But, buildings can be your friends.

I'm down. Id' have to be in my Jeep since my base isn't hooked up, but I'll give it a go.

Nice! Congrats!

With the Aurora we had, I had hoped band conditions for 6m would be good. Nice to hear it was working out.

I found out the hard way about that. I have a 1,000w tuner that I pushed about 700w of digital through, and smoked that very expensive tuner. Same thing with my balun. I thought a 1,500w balun would take 700w-800w of digital, and it did a few times, but after a few transmissions, I watched it explode like it was hit by lightning. I ended up have to buy a 5KW unit before I stopped smoking them.

Glad it's working out for you! I love experimenting with different options and its always fun when it works!

Hey everyone... I just want to take a moment to apologize to Ray @WRYS709 . He asked a genuine question about headphones vs. headsets and why I responded the way I did. I am pretty sure Steve was teasing him a bit and I piled on, just joking around and having fun... kind of like the "some people" jokes Randy blessed us with. I forget that we are not all friends in our personal life and that sometimes jokes come across as insults. Ray was kind enough and had the grace to reach out to me privately. With kindness, he let me know that he felt what I did was not very nice. While there was no ill intent on my end, what is important is the end result. With that said, Ray, I apologizes. I upset you publicly, and I am apologizing publicly. Thank you for showing me grace.

There are call signs that are assigned to certain government roles, rather than the person. While he is in office, he could use any call sign that is assigned to POTUS. As far as DJT is concerned, he can apply for a license, and depending on any convictions existing at the time of application, and the nature of the crime(s), and the FCC would evaluate if any conviction would be exclusionary. Since he has no felony convictions related to abuse of radio/technology, it's extremely likely his application would be approved.

You asked if my headphones included a microphone, which by its very nature makes it a headset. Then asked what made me think you asked you about a headset. Now you are upset because Steve is teasing you a bit because of it. Just my opinion, but I think you may be overreacting a bit. We're genuinely contributing to the conversation... After all these years, I expect nothing less. It's almost every thread. Same in most forums... plus, if someone quotes a person you are ignoring, you can see their post in the quotes. I just got a cheap set of Stereo/Mono headphone from Avantree with 32 ohm impedance. They work really well for my mono out radios, like my GMRS and VHF/UHF radios, as well as my mobile HF radios. I just use the mic that goes with the radio, for all of those uses. However, I got a Heil Pro Headset for my IC-7300. The headphones have fantastic audio and the mic is the same element that is in my PR-781G boom mic. It's a fantastic set. It does have the 1.5 k ohms impedance for the output. I will also use my Avantree headphone with my IC-7300 when I am using my boom mic and monitor.

I was thinking the same thing. LoL

I didn't buy a headset, I got headphones. I move them between all of my radios, so having a mic built-in was not an option. I do have a dedicated headset for my HF radio, but they were over $500. If you want details on either, let me know.

I just bought a set of mono headphones with the right impedance.

At the bottom of this post, I put copies of both my licenses that I just downloaded minutes ago. No reference to Line A or C. Also, I shared this content back in August.... https://forums.mygmrs.com/topic/10559-im-north-of-line-a-and-just-made-a-big-mistake/#comment-112976 Okay... really quick... the short answer is those people on the net are incorrect. You can use all of the GMRS channels anywhere in the US. Details without getting too dorky... what used to limit us was a combination of FCC rules and a US/Canada treaty. The treaty is called "Agreement Between the Government of the United States of America and the Government of Canada Concerning the Coordination and Use of Radio Frequencies Above Thirty Megacycles per Second, with Annexes" also known as the "Above 30 MHz Agreement". A new agreement that was signed in 2021 supersedes that agreement. The new document is called "General coordination agreement between Canada and the United States of America on the use of the radio frequency spectrum by terrestrial radiocommunication stations and earth stations." This document discontinued the parts first treaty I mentioned, that impacted GMRS. Now, that only relates to the Treaty / Agreement. Under FCC rules, the restriction was also lifted. The older rule was under "§ 95.1761 GMRS transmitter certification" (e). However, § 95.1761(e) now has new text that is completely unrelated. Also, Line A is not referenced anywhere in the Personal Radio Service general rules, nor in the GMRS specific rules. The original text from the FCC (from the wayback machine), again no longer valid, is noted below. § 95.1761 GMRS transmitter certification (e) GMRS transmitters intended for use north of Line A or east of Line C* must not be capable of transmitting on channels 462.650 MHz or 462.700 MHz (GMRS Channels 19 and 21), unless such operation is specifically authorized by the Commission pursuant to an application showing that harmful interference to Canadian stations is unlikely.*
