Your radios TX is transmit. Your radios RX is receive. The repeater is going to RX (recieve) your TX and TX (transmit to your receive) RX. Yes it can be complicating. What you need to remember is the TX and RX listed is where you need to program those numbers for your radio. Hope that helps.

Like @Sshannon said, your farz probably wont change in any way that you will ever see or notice, but just knowing that you have that additional power feels good.

The range probably won’t change much , but if you like the features of the 500, go for it. There is a certain psychological comfort in knowing that you have the maximum allowed power, though.

Honestly, I think more information is needed. Unless this is a thought experiment, like Schrödinger's Cat.

Generally you download from the radio first, SAVE THE FILE, then make your changes, THEN upload.. The download confirms that you have the correct radio and comm port settings selected. Are you able to download?

I have nothing against the GM-30 it just isn’t my choice. Your argument against the radio I mention is flawed as in your stated scenario one wouldn’t need to replace the radio or the battery with the radio I mentioned and I don’t mind handing it over to family. I want them to have a good experience too. I’m the kind of guy that gives his wife the better steak. That’s just me. I also don’t leave ice tea or my radios in the car for two days but to each their own. OP has options and depending on his needs now he has more info for an informed decision.

For simplicity and quality I agree with @pcradio on the KG-S88G. It’s superheterodyne, it’s IP67 waterproof, small and easy to use. I got one for this very reason of being able to hand it to a family member and know that it’s not over complicated.

Get ready for sticker shock with Pasternack. ABR Industries is a good US made equivalent to the genuine Times Microwave LMR400. You can purchase directly or from most of the ham radio dealers listed previously. https://abrind.com/cable-overview-abr400-pn24400-2/

I'm no guru either but I recognize the value of real-world examples.

Any death that occurs from Hurricane Hillary will be ruled a suicide!

All of the above statements should answer the question. I hope these examples are helpful. A local tech guru built a 3 watt portable repeater setup. We set it up at 8,000 feet against a mountain side, effective range 30 miles for 120 degrees. Relocated it to 6,000 feet lookout, effective range 50-60 miles. I have a 4 watt Gmrs setup at my house with the antenna 14 feet up, effective range 5 spotty miles. Moved it one mile south 100 feet higher, effective range 15 plus miles. But I do not hold guru status. Good luck with the hobby WRJA397

I recommend watching Notarubicon videos on YouTube. I wouldn’t go high end at first; I would buy something low to mid level and play around with it to learn what features are important to you. Nobody buys just one.

I got my 50FT of LMR400, pre-cut with ends on it from Amazon.. Was delivered the next morning.

Let’s say you have 30 watts at the SO-239 on the radio. Then you have the impedance mismatch so a certain amount is reflected back into the radio. That leaves 20 watts going in the direction of the antenna. Then you have a loss of 1.7 dB, which is about 30% of the 20 watts that’s lost. So you’re down to about 12 watts. I’m estimating rather than calculating so these are pretty sloppy numbers. You don’t say whether the antenna gain is dBi or dBd. Assuming the best you’ll have about the same RF in certain directions as 25 watts in an isentropic antenna (it really is only 12 watts, but in some directions the RF field will be as strong as a 25 watt signal into an antenna with no gain.

You, ah, might want to dial back the belligerence a bit if you want anyone to be willing to help you the next time you have a question...

Thanks Randy, great video.

People started telling me about this a few months ago and I thought they were full of it, but I finally saw the listing on Amazon... My biggest issue I see is the confusion it will cause when telling "some people" that you're using a UV-5R on GMRS - "some people" wont know if they should report you to the FCC or not. Rumor has it that a very popular and beloved YouTuber will be making a video about this in the coming days.

Welcome to myGMRS. I own many of the GXT1000 radios. They will permit you to hear, but not talk on repeaters. They are designed for simplex communication only, and are in the same league as bubble pack FRS radios. The FRS and GMRS share 22 frequencies, all of which are used for 2-way simplex communication (radio-to-radio). Because the two services share these 22 frequencies FRS and GMRS radios may intercommunicate in the same way that FRS-to-FRS radios can. The gem of the GMRS is that repeaters are allowed, and to support this the FCC has allocated 8 additional frequencies that are reserved for communication to and through a repeater. The GXT1000 does not have those frequencies. A repeater uses two frequencies. One that is listens on, one that it transmits on. A repeater-capable GMRS radio will have the ability to use two frequencies as well. When communicating through a repeater your radio will also transmit on one frequency and receive on another. If, for example, your handheld is working is working a 575 repeater, then your radio would transmit on 467.5750 MHz, the repeater will receive your signal on 467.5750 MHz and then retransmit it on 462.5750 MHz and your radio and others will receive it on the 462.5750 MHz frequency as well. This is called Duplex communications. You can hear the repeaters on you GXT1000 because the 8 frequencies that repeaters transmit on are 8 of the same frequencies also used for simplex communications. So, the bottom line for you is that if you wish to communicate through repeaters you will need the following: - A repeater-capable radio. - Permission from the repeater owner to use their repeater. - Correct programming of the radio so that is transmitting on the correct frequency using the CTCSS or DCS code given to you by the repeater owner, and receiving on the frequency that the repeater transmits on. - Operate within the usable 2-way coverage range of the repeater and your radio. Hope this helps. Michael WRHS965 KE8PLM

I had it easy.. one house two streets down has major issues.. One corner of their foundation is undermined.. And these are new 3 year old houses. They did not have landscaping and the ones that didn't have lots of work to restore their property. Lots of mud everywhere and undermined sidewalks everywhere.. Gonna take awhile for the city to clean this mess up..

Dude asks about hearing Morse code on GMRS. 23 hours later an argument breaks out on the same thread about who pulls cable for HP.
