Transmitting Power Limits
AdmiralCochrane and 3 others reacted to OffRoaderX for a topic
No. Getting a bigger/better antenna and/or getting it higher will help more.4 points -
I don't understand what the confusion is. 95.335(a) clearly says that an exception must be listed in the applicable subpart and Subpart E for GMRS does not have any exceptions listed. How is this a debate?4 points

Transmitting Power Limits
AdmiralCochrane and 2 others reacted to Lscott for a topic
Which reminds me of the people who want those "High Power" HT's claiming 10 watts plus output. I don't have a link to it but there are some FCC specifications for specific absorption limits based on frequency. Hams are "supposed" to do basic RF exposure calculations above certain power levels at various frequencies per the FCC for RF safety.3 points -
Transmitting Power Limits
AdmiralCochrane and 2 others reacted to OffRoaderX for a topic
As @SteveShannon, certified & anointed H.E.R.D. mentioned, there is no limit specific to handhelds. And if you look hard you will find several 8W units, and if you really apply yourself, you might even find a 10W or two.. But it is important to understand that in most cases, on-average, usually, most of the time and in most situations, most people will not notice any difference between 4 or 5 watts and 8 or 10 watts other than noticing the battery draining much faster.3 points -

..we will reserve judgement for now. With a UV9g, you dont need to think about the offset - these are the basic steps: Put the radio on the correct REPEATER CHANNEL - Probably listed as either "Repeater 20" or Channel 28 Go into the Transmit CTC menu and enter the tone IGNORE/REMOVE the Receive tone as it is optional and at this point its only going to add to your confukulation Be sure to save all your changes (you may need to resort to the manual) Push the talk-button and talk, let go of button and listen for the Kerchunk/Static back from the repeater, or someone responding If it doesn't work then either you have the wrong channel, the tone is wrong, you are not close enough to the repeater (just because you can hear it does not mean it can hear you) or the repeater is down/broken/offline. The fact that you said you "have the offset" leads me to surmise that you've done it wrong.2 points -

Transmitting Power Limits
AdmiralCochrane and one other reacted to SteveShannon for a topic
The hill is going to do what it does. Where that additional power sometimes can help is if you’re transmitting through vegetation. Vegetation attenuates the signal so more power can make a difference. Hills block the signal and power won’t overcome that. But a high antenna can. In fact the single most effective improvement most people can make is to get their antenna up in the air. The second is to feed it with a cable that doesn’t convert the signal to heat. Power is way down in priority.2 points -

Many people use the Midland models that are fully water/dust proof and have the built-in intercom port/plugs in them. They also have a simple screen and simple controls (only 1 or 2 knobs) - which is useful when plowing through vegetation and animal habitats at unsafe speeds while drinking beer with the music blasting at full volume.2 points -
Under FCC Definition, handheld radios are mobile radios. Straight from § 95.303 Definitions. Hand-held portable unit. A physically small mobile station that can be operated while being held in the operator's hand.2 points
-
You are absolutely correct. Although, Part 95.335(a) gives an exemption for Part 90 LMR radios to be operated in Part 95 radios services and there no rule or regulation saying differently in writing. There are no expectations that any rule, regulation, or statute to have any e.g. and e.g.s are not binding or make it regulatory to the rule where examples are giving. As I previously stated, certain exceptions are given in each subpart regarding how a Part 90 LMR may be operated on the respective freqs. Also, listing the two e.g. references was a mistake and should never have been written in 95.335(a).2 points

Unless specifically called out a handheld is regulated the same as a portable or a mobile. Thus, while not practical, you could have a 50 watt handheld on some of the channels.2 points -

AdmiralCochrane and one other reacted to LeoG for a topic
This is why you need stupid people to write the actual regulations. They'd spell it out instead of referring to this which refers to that which in turn refers to something else. Reminds me of reading the NEC regulations where you need to look at the whole book every single time because nothing is stated in a sentence that doesn't refer to some other part of the book.2 points -
Are RV TPMS sensors operating at 433MHz FCC permissible?
SteveShannon and one other reacted to Lscott for a topic
YES. Unfortunately the FCC allows a bunch of other crap to operate there as well. https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A/part-15/subpart-C/subject-group-ECFR2f2e5828339709e/section-15.240 Some examples: https://hackaday.com/tag/433-mhz/2 points -

I don’t agree. Although the numbers of two examples of exceptions are listed, one from subpart C (RCRS) and from part E (GMRS), the actual exception belonging in the GMRS subpart no longer exists and thus cannot apply. 95.335(a) clearly says that an exception must be listed in the applicable subpart.2 points -
It does not say that it is permitted. It says if there were exceptions, they would be listed, and they aren't. Insults from people like you are meaningless to me.2 points

GMR2-PLUS Channels on a KG-1000G
AdmiralCochrane reacted to amaff for a question
Nope. A lot of them do because it *can* decrease confusion in new users. What's required is that the radio enforce the rules. The rules don't say anything about what memory slot a frequency sits in. My "nice" GMRS radios (nice for me...), KG-905Gs, will force the radio to low power if you put, say, GMRS Channel 8 in memory slot 20, or allow high power and frequency offset for repeaters channels if you put them in, say, memory slot 8, where a low power interstitial channel would normally go. Lazily programmed (from the factory, I mean) radios force things rigidly in place because it's easier than enforcing the rules more broadly.1 point -
Since the uv9g is a GMRS radio it is pretty hard to mess up. Some things to think about: Are you close enough to the repeater? If you know the general location you could move closer to it until you are sure you are actually opening the repeater. Have you tried simplex with another radio to make sure your radio is transmitting? Is there traffic on the repeater? I'm sure you have double checked your RX/TX tones but you might want to leave the RX tone off if the repeater has one so you can hear all the traffic on that frequency. I'm sure others will chime in with things I didn't mention. Don't give up.1 point

LoRa Distance Record
SteveShannon reacted to WRYZ926 for a topic
Here is another example of how changes in the atmosphere effects UHF radio waves. My bother and I both have Allstar nodes and both were set to the same frequency and PL tones. These nodes only put out about .05 to 1 watt of power on transmit. And we have our radios set to 5 watts or less when using the nodes. We are 19 miles apart and 5 watts is normally not enough for us to hear each other. The other day there was a storm cell in between us and we could hear each other. My brother was using his Allstar node to talk to guys in Texas. I could hear him but not the other people. He could also hear me when I was using my node. The storms and low cloud cover was bouncing the 5 watt signal 19 miles. Granted neither one of us had a very strong signal as the signal strength meters barely moved, but it was enough of a signal that we could hear each other. We both ended up changing the frequency that our Allstar nodes use to stop this from happening.1 point -

The service is primarily designed for that use, but you are not restricted to that. It is a "General Mobile" service so the only limit is your imagination. You can use it for business as long as everyone is licensed. You can use it as part of a neighborhood comm backup in the case of an emergency. My HOA, for example just announced that channel 15 would be used if all else fails (seriously considering a repeater). Don't forget that it shares channels with FRS radios, so in a close group you can connect to a number of unlicensed knuckleheads. Welcome to GMRS!1 point -
20w mobile with 5w handhelds
GreggInFL reacted to SteveShannon for a topic
Aluminum is a very good conductor and makes a fine ground plane. It requires additional work beyond a mag mount though. Either attach a piece of ferrous metal for the magnet to hold or drill a hole and installing a permanent NMO mount. That’s the hardest part. Otherwise just put a repeater in one of the cabinets and run coax to the antenna mount. To power the repeater you will probably want a battery which is charged whenever you have shore power or while attached to the tow vehicle. Time to shop!!1 point -

Are RV TPMS sensors operating at 433MHz FCC permissible?

Sounds funny, but it's a real thing. Some Ham 70cm repeaters had to be dialed down in power level to stop interference to Pave-Paw radars. https://www.arrl.org/news/new-70-cm-coordination-agreement-reached-for-new-england https://sites.google.com/site/arrlsacvalley/pave-paws1 point -
"Illegal" radios
wrci350 reacted to SteveShannon for a topic
Yes, part A applies to all of the other subparts. Part A says that radios must be certified specifically in accordance with the requirements of the subparts but that there may be exceptions to that requirement. Part A goes on to say that the exceptions must be listed in the subparts and gives two linked examples. But if you click on the link to the example of the exception listed for GMRS, that exception no longer exists. Thus, there is no longer an exception that allows transmitters certified for other services, such as 90, to be used for part 95E. For example, a newly manufactured transmitter for part 90 may be used for part 95E if and only if it has also been certified for 95E.1 point -

This could be the subject of a whole other thread since this seems to be an area of some dispute. The disagreement is how and why attorneys exist and make their money, arguing over the law. I once read the following that was told to recently licensed attorneys. "If the evidence is against you, bang on the evidence." "If the law is against you, bang on the law." "If both are against you, bang on the table."1 point -

WSIA887 reacted to SteveShannon for a topic
Radio specs are submitted by the manufacturer to the FCC and the FCC issues a certification. Look and see if the radio has been certified. A certification identifier should appear on a label attached to the radio. However, you’ll soon learn that as long as you make any attempt whatsoever at following the rules the FCC will never know or care.1 point -
I do, though. Everyone in this thread is henceforth banned from using GMRS. Banned, I say! Edit: ah, dang it.1 point

@OffRoaderX went far beyond sharing an opinion. I genuinely cannot imagine why anyone would be annoyed by use of the phonetic alphabet unless it's because "some people" think it's a symptom of trying to be a ham in a GMRS community. I think part of the reason hams use the phonetic alphabet so much is that amateur radio is international. It can be pretty hard to understand someone whose first language is not the same as your own, especially the pronunciation of some letters. Just think of how much "B" and "V" sound alike in Spanish. GMRS users almost never talk to someone in another country, so being understood is not as much of a challenge (unless you're in California). Furthermore, shorter wavelengths have higher frequencies, which typically improves clarity in voice signals. Even the difference between 70cm and 2m can sometimes be discernible. If you're playing around on 80 meters, you're going to repeat yourself quite a bit. GMRS, being at the higher end of the spectrum, rarely suffers from poor quality of voice signals. For the most part, if you can punch the signal through, you'll be understood. Simply put, GMRS users don't use the phonetic alphabet because we don't need to. It's easier for me to say "WRTC" than "Whiskey Romeo Tango Charlie", but sometimes I'm going to use the phonetic anyway. I have 33 years of using the phonetic alphabet in uniformed service and I also participate in amateur radio. It happens. I just don't understand why anyone gets their undies in a wad over it.1 point

So there it is. Control, and the fact you have none. And other GMRS operators trying to move in on your woman. Maybe it is effecting things in the bedroom. Maybe I shouldn't have gone there. NAAA, your a control freak and want ALL GMRS users to conform to your interpretation of the service. That ain't happening. And worrying about guys that use phonetics for their call signs as a rule... your concerned about them? They ain't seen female reproductive parts since they were born and women don't speak to them like that unless they are getting paid to do so. That's who you are worried about. There are little blue pills for that if you aren't taking care of things yourself to the point those people are a concern. Because it is now an AOL chat room. It's being used as a social communications platform, like it or not. If you don't like it, call the FCC and turn them in. They will laugh at you same as we are. And they will do NOTHING. And telling me to take MY repeater down.... again, keep hoping, but I will tell you that ain't happening either. I invite all users and all types of traffic to my machine. If YOU don't like the content, the channel knob is right there on the front of your radio. Go elsewhere.1 point

Why do I catch this nonsense first thing in the morning and feel compelled to even bother to say something? First off WTF are you talking about? Are you referring to someone putting out there call sign on a repeater to see if others are also on the repeater? You answered that question in your own before anyone else ever could, THEY ARE BEING SOCIAL It's sort of HOW THEY CHOSE TO USE THE SERVICE. WTF do you care? You decided to post about it here so it must really effect you. Do you loose sleep at might over it? Does it plague your dreams? Is effecting your performance in the bedroom? The cure for any and all of that is tuning your radio to a channel without a repeater and turning off the scan function. Then you will NOT hear those pesky SOCIAL GMRS users calling out their ID's morning noon and night being social. And Randy, if you are looking for a topic for a video how about No being a TROLL1 point

Motorola M1225-LS Repeater Question
WRZI840 reacted to SteveC7010 for a question
You are looking for 1225LS_RSS_V3.0.zip. I have a copy of it which is about 5 meg in size. It's designed to run on WinXP or Win95. For best results, it should be run on an older machine which has a true serial port (COM1). If you open the radio and it has an LTR Passport accessory board made by Scholar-Johnson, you can simply remove the board and the radio will revert to a standard M1225 which can be programmed with the version 4.0 1225 HVN9054 software. The Scholar-Johnson board is desirable by some hobby folks. I sold one on Ebay in less than a week.1 point
