    Marius1195 got a reaction from NKnetzer in Opinion on BTech GMRS Pro   
    Not digging it atm. I think if their product blows up and most of the cool features are usable I might change from a 3 star to a 5. As of now, I am very meh about it. I should mention it did xmit at 5w as advertised and iirc my swr was around 1.2 with their antennea. Lastly they do not have a CS line. Sending them an email is the only option. This might have a lot to do with my displeasure now that I think about it.

    Marius1195 got a reaction from SteveShannon in Mobile with 12v adapter recommendation?   
    Thanks for the feedback all. Had a boo boo off road and put a dent in my oil pan right where the drain plug was so when I went to change the oil I found I needed a new pan. Ended up using my radio funds for that little mistake. I will be aquiring one, but probably early next year. Thanks again and happy holidays!

    I wasn't aware of the plane not being as significant; that was the reasoning behind the location I used. I can move it and get a better route easiy enough. When you mentioned white electrical tape my immediate though was Unicorns and Bigfoot, does it really exist?! ? Thanks for the tips. 

    Heading to Stl today. I am pretty excited to see the difference the roof antenna makes. I live by a farily decent sized lake in the sticks and there isn't much traffic within 30-40 miles of me.

    Free is ALWAYS the right price.  ...and if your 213 is free, then you can afford to buy a slightly better antenna to make up for the loss.

    Marius1195 reacted to WRAF213 in Why "More Power" Isn't The Answer   
    Absolutely, finding higher ground should be the first step towards improving a setup. Running more power only matters on fixed setups where the antenna is already as good as it can get, or on mobile operation where there is no 'finding a good spot'. Even then, there's not a huge difference between 15 and 40 watts.
     
    Here's my first piece of advice for new users (and I have a bunch, fair warning): use scan mode on a radio that will tell you the active CTCSS tone or DCS code if you're looking for repeaters to use. RTL-SDR is also a good tool, and makes the entire 462 MHz band visible with good sensitivity and excellent selectivity.
     
    Especially on fixed setups, grounding is important. Noise will get picked up along the coax and travel up to the antenna, where it enters the receiver. The effect is very apparent on SDRs, where the noise floor is directly visible. When grounding a setup, check for ground loops with a multimeter.
     
    Learn to recognize the busy-channel indicator on your radio. When the radio detects any activity on the channel, regardless of correct CTCSS/DCS, it'll turn on the busy-channel indicator. It'll help you to know if you have the correct CTCSS/DCS for a particular system. Some repeaters use multiple CTCSS/DCS, so this indicator can be useful on those repeaters to make sure you aren't interfering with a different conversation. On Baofeng's radios, this is the green LED on top of the radio. On Motorola's commercial radios, this is a blinking red or green LED near the antenna; on their FRS/GMRS radios, this is the red LED above the display.
     
    Some repeaters transmit CTCSS/DCS back to you, but only while someone is transmitting to it. If you're hitting the repeater but can't hear it come back to you once you finish transmitting, this could be a possible cause. Use the monitor feature on your radio or check the busy-channel indicator to check for the repeater's tail.
     
    Don't be afraid to try simplex. If you hear a callsign with variable signal strength, they're probably not going through a repeater. It's rare to find contacts that way, but that's largely because hardly anyone calls for contacts on simplex. 462.5625 (channel 1), transmit and receive CSQ; and 462.6750 (channel 20), transmit CTCSS 141.3 and receive CSQ are good places to try calling CQ.
     
    People who use MDC-1200 on their radios don't actually have to hear the data bursts, the radio can detect the burst and mute it. It gets annoying so most people with MDC-1200 radios have their radios like that.
     
    This forum sure does love their Kenwood TK-880s and Motorola M1225s. They're great radios, but terrible general-purpose radios. Virtually all commercial radios can only be programmed by computer software, so you have to know ahead of time what you're going to talk to. Speaking of commercial radios, used Motorola HT1000 radios are incredibly durable and inexpensive. They use the same programming
     
    Don't waste your money on the BTech GMRS mobiles, the quality control is practically absent. The GMRS-V1 is apparently alright and Part 95 accepted. Use CHIRP for programming; it will save a lot of time and headaches, while allowing for named channels.
     
    When buying a used radio online, make sure the frequency range actually includes 462-468 MHz. For handheld radios, make sure that you are getting (or already have) a charger and antenna. The battery is probably shot, so include a replacement in your budgeting. I like to have at least one spare battery, so I can continue using the radio while a battery is charging. Don't transmit on a handheld radio while it's charging.
     
    Counterfeit antennas are a thing, especially with Nagoya. Buy from trusted sources, or find a friend with an antenna analyzer or VNA who'd be willing to show you how to see if an antenna is good or trash. Be willing to learn how to use test equipment, or at least be aware of what that test equipment is testing. It'll help greatly in the future when you are faced with new problems.
     
    GMRS isn't ham radio, but it's often used pretty similarly to 70cm. Ham radio clubs are still a useful resource where you can make lots of friends with lots of knowledge. If you don't have a ham license, they'll pressure you to get one. A Technician-class license is easy to get, costs much less than your GMRS license, and you may even be able to use the same antenna for 70cm. Different clubs have different focuses, so don't get discouraged if you don't feel a particular club is right for you. Depending on the area, hams may not like GMRS for one reason or another; but recognize the common interest in establishing reliable communications between licensed operators.
     
    There's a 30 MHz gap between 70cm and GMRS, so most 70cm antennas with appreciable gain don't work on GMRS (and remember you're usually transmitting at 467 MHz, not 462 MHz). Check your antenna's documentation to see how much bandwidth you have. Most handheld antennas are broadband enough, and most commercial-band antennas actually work better on GMRS.
     
    Don't put up a repeater until you know exactly what you're doing. There's enough deaf GMRS repeaters out there. Don't take on the task alone, either. The more support you have, the better (and, for you, cheaper) the repeater can be. Even a low hilltop provides significantly more coverage than a rooftop repeater. Sites cost money, but can cost a heck of a lot less if you get to know some repeater folk and can make a good sales pitch. Don't use LMR-400 for repeaters.
     
    Getting above the roofline makes a big difference in suburban areas, particularly when trying to work hilltop sites. For more rural areas, try to get above the treeline if possible. If you're the only one-story house in a block of two-story houses, ouch.
     
    Be it ham radio or GMRS, remember that the radio hobby is about communication. This includes, but is not limited to: rag chewing, technical talk, emergency communication, repeater building, proselytizing the wonders of properly configured radios, and being willing to help the confused. A lot of people out there try to assert their dominance over a channel and run around with a better-than-thou mentality, and over the course of your license you'll find at least one of them. They aren't out to improve either service or what each service stands for, so stay away from them. Don't let them change your perception of the radio hobby, either.
     
    If you hear confused FRS users on channel 1 that can't get their radios to talk to each other, offer to help. Transmit CTCSS 67.0 and receive CSQ. They'll probably need help configuring CTCSS on their radios. Ask for the model number and look up the manual on Google. Stuff like this happens more often than I'd like to admit, and half the time those people spent a lot of money on those radios. Be a good citizen.
     
    Some repeaters will beacon out their callsign. That doesn't mean there's anyone using it. Repeaters aren't supposed to do that, but not everyone has a good repeater controller. It's almost universally agreed upon that such repeater behavior is super annoying.
     
    Not all repeaters identify, and that can make it a pain in the rear to figure out who owns the repeater. It's usually private repeaters that don't identify, and some legally don't even have to. It's another fact of life that makes frequency coordination difficult for repeater owners.
     
    The FRS channels, especially 1-14, are flooded with business users. They're allowed to be there, and aren't looking for conversation. Let them be. They're close enough together (a few hundred feet, typically) that they won't even notice you're on the same frequency as long as you're on a different CTCSS/DCS code.
     
    Not everyone is following the rules. Report egregious violators to the FCC, but don't expect enforcement action. Report criminal activity (eg. terroristic threats, use of radios in a crime) to law enforcement, not the FCC. If you happen to know who the perps are, tell the FCC as well. You probably won't encounter any such activity.
     
    If you start getting involved in the commercial radio users crowd, be it on 70cm or GMRS, you'll see a lot of brand loyalty. I'm a Motorola guy, since those are the first commercial radios I got involved with and those radios meet all of my needs. We have a lot of Kenwood folk on here, and boy do they love their TK-880s. Both make rock-solid commercial radios. There's other brands out there, too. Stay away from cheap Chinese radios, those are markedly not rock-solid radios and may not have any type-acceptance whatsoever. It's generally accepted that radios with commercial (Part 90) type acceptance are fine for GMRS (Part 97E) operation, since Part 90 requirements are more stringent in terms of RF performance. While the FCC is yet to make an official exemption, they allude to it frequently in the 2017 rule change discussion.
     
    Directional antennas (mostly Yagis or log-periodic antennas at these fequencies) are terrible general purpose antennas, since you need to know the direction towards the stuff you want to talk to. Commercial omnidirectional antennas covering 460-470 MHz at a minimum make the best general-purpose antennas. Browning's BR6157 is a good starter antenna, with some gain and a wide bandwidth. If you spend more than $60 on one before any sales tax, you've overspent.
     
    Use FakeSpot when shopping for radios or accessories on Amazon. Don't get ripped off by fake reviews.
     
    Monitor channel 1 (again, transmit CTCSS 67.0 and receive CSQ) during disasters. You may save someone's life. Prioritize your safety highest; you're still a victim.
     
    Don't be a dillweed on the air that hides from consequences behind a microphone; respect is reciprocal. Not everyone you'll meet understands this.
     
    When you got your GMRS license, your whole family just became GMRS licensees as well. Come up with a separate simplex channel for them and them only. It's useful when outdoors, communication between vehicles on road trips, or during disasters. Having a nationwide license to operate a radio without frequency coordination, and with unlicensed operators on FRS, is a beautiful luxury we have on GMRS that you will get nowhere else. Make sure to test your channels ahead of time, and check them regularly if you don't use them often.
     
    I mentioned it earlier, but I'll elaborate on it: RTL-SDR is an excellent tool for GMRS. All of the output channels are visible with a spectrum analyzer-type visualization. Interference becomes easy to spot and identify. CTCSS and DCS decoding is straightforward and nearly instant, and works with hardly any signal strength at all. Signal strength readings can be calibrated against an absolute scale (dBm), which allows for comparison between antennas and locations. A fancy setup of them, Kerberos SDR, can do direction finding with real-time map plotting, but requires some technical knowledge. SDR is fairly recent, and there's plenty of user groups online (like Reddit's r/RTLSDR). When shopping for RTL-SDR, don't spend more than $30 for a bare unit, and don't buy anything that doesn't have a 1.0ppm TCXO or better. If the item description doesn't say TCXO, it doesn't have one.  RTL-SDR Blog v3 is a good unit, and the Nooelec NESDR SMArTee performs the same. Throw the RTL-SDR Blog 20dB LNA on there as well, life will be much better. Use a USB 2.0 extension cord with SDRs.
     
    Talking on a handheld radio while driving a vehicle is illegal in California under the cell phone laws. Mobiles, with a simple PTT-only hand mic, are fine.
     
    Don't get a 16 or 48 channel radio as your first real commercial or commercial-grade radio. Go for something with at least 128 channels and a screen. Get the programming software and cable before you get the radio so you aren't stuck with a paperweight. Don't give money to HamFiles.
     
    If you have a lot of long conversations but all you have is your handheld radio, get a mobile radio and a power supply. Use a proper antenna (as discussed earlier) and some low-loss coax (RG-8, LMR-240, or better). PL-259/SO-239, also called the UHF connector, is a terrible connector at UHF. Avoid it wherever possible. Use TNC or N for permanent or semi-permanent connections, and BNC for connections you switch out a lot. Keep your connectors clean and seal any outdoor terminations. Assume each adapter adds 0.5-1dB of loss, so use as few adapters as possible. Get your coax terminated in whatever connector your antenna has; don't leave the adapter outdoors. Mastic tape gums up over time and future you will hate present you. If you use cheap non-outdoors coax like I did, it can get water ingress. SWR will still show a rather normal reading, but the wet insulator will suck up all your RF (easily 99% of it).
     
    Good coax is thicker than you think. Take that into consideration.
     
    Folk at your local ham radio club, or GMRS club if you live in an area with one, have done enough fixed radio installations to be able to help you with yours. Don't go out alone and do it, but take some notes so you can eventually help others. Honestly, they're not that hard.
     
    If you're in a place that gets thunderstorms more than a few times a year, lightning protection is a real concern. Nothing will stop a direct strike, so unplug your equipment during such inclement weather. That's another reason to keep portable radios around.
     
    Repeaters almost always use hardline instead of flexible coax. Hardline is expensive and requires special tools. Good feedline is critical on repeaters because you usually have a 40-watt transmitter on the same antennas as a sensitive receiver. Slight non-linear effects, even a rusty fencepost nearby, can cause issues with receiver performance.
     
    If you have an opportunity to visit a hilltop repeater site (an opportunity you may get if you're involved with repeater groups), take it. The first trip to one is an experience, and you'll get to see a variety of real-world installations. Hilltop sites are surprisingly dirty; nobody's up there keeping the floors clean. Some sites are cleaner than others. It's often a long drive and fair distance from civilization, so bring a lunch and go to the bathroom before the trip. Some sites require four-wheel drive and an experienced driver to get to. Buy their dinner.
     
    Flat areas can get significant coverage from a low-level repeater. Rooftop repeaters actually have decent performance in those environments.
     
    Even on rooftop antennas, your simplex range to a five-watt mobile/portable can be as short as two miles. GMRS is heavily influenced by line-of-sight propagation. Building penetration is better than MURS or 2-meters.

    Finally, got my Ultimax DX Extreme 72' Random Wire Antenna up. Mounted the transformer/unun to the bottom of a bird feeder with RG58 and counterpoise wire down bird feeder pole. In a vain attempt to hide it a bit from the HOA.
     
    The other end is tied to 50Lb Mono filament that I was fortunate to hook around the LNB of a satellite dish mounted to the chimney. This took several attempts, one attempt resulted in a cut monofilament when I hooked the angle adjuster. One attempt nearly end my day as I started to slide off the roof. Resulting in a lot of pulled muscles, burns from the hot shingles. *** it was a lot steeper then I thought originally. I do not recommend climbing the roof. Hire someone.
     
    The RG58 runs down the pole, I have yet to trench the RG213 from the DX Engineering NEMEA box which I had finally got installed and grounded the previous weekend.
     
    Sadly, now waiting on RG400 for the patch lines into the shack. Now I am contemplating switching from LMR400 to RG400 for the feed line to the 2m/70cm antenna in the attic.
     
    The bird feeder antenna in all it's glory. Photo is before the antenna was pulled and counterpoise was buried.

    I will through in my two cents on this one.

    I too own the 771G and take no issues with it. But admittedly I have stopped using it as I have reported before. The reason being is its size. I did do some on-air comparisons between my radio’s stock antenna back-to-back after I received it and perceived an increase in range of perhaps 5-10%. What this translates too ultimately is that if you are on the absolute fringe of another radio having it may make the difference between whether you hear only noise or just barely hear audio, and the same for others listening to you. If you are not on the fringe you and others may not notice any difference whatsoever.

    While I am glad to have it as a backup/spare, for an everyday carry user the performance increase does not adequately offset the inconvenience of the longer whip where an how I use it. YMMV.

    The point being, don’t expect night-and-day performance differences. Get one, but expect relatively minor, just barely noticeable differences only when in the fringe area of another radio.

    This topic brings back a memory from the very early 1980's when I was young.
    My dad was a semi driver all his life and back then we lived in a trailer. He had a CB base station with a tower and a fiberglass CB antenna. Which the antenna came in two sections with a metal couple in the middle and had a metal tip.
    One night there was a nasty lightning storm. That night lightning hit the CB antenna blowing it up in little tooth pick pieces. Few days later we found the metal couple fused together and found the metal tip in the cornfield like 200 yards away.
