Does Power Output Matter? (Hint: NO!)
SteveShannon replied to OffRoaderX's question in Technical Discussion
4 to 60 watts is nearly 11 dB. (4 to 40 is 10 dB). -
New to GMRS and looking for a better antenna..
SteveShannon replied to WSIZ258's topic in General Discussion
You need the T-DCS code to get into the repeater. You can hear everything the repeater transmits without an R-DCS. If you’re using a GMRS radio and you’re using a repeater channel the offset is automatically added. -
Does Power Output Matter? (Hint: NO!)
SteveShannon replied to OffRoaderX's question in Technical Discussion
Does not matter in what way? Range? Clarity of reception within that range? I agree that in the open, two watt handhelds with a rubber duck antenna will transmit clearly as far as the curvature of the earth will allow. But if transmitting from inside some attenuating material, such as vegetation or even a building or vehicle, the extra 7 dB of power can make a perceptible difference. -
37 continuously, 50 amps at a 50% duty cycle.

Baofeng gm15pro shows long antenna included, but not shipped?
SteveShannon replied to a topic in Guest Forum
I’m wrong. My TYT and Wouxun radios arrived in white product boxes. One of my Baofeng (GT5R) arrived in the exact same kind of brown cardboard box as @WRTC928 showed in his photo. No product box between the cardboard box and the plastic liner. My original Baofeng UV5R arrived in a larger white box. It was the only Baofeng that I received with a long antenna. -
I’ve never seen a mobile radio designed to fit either a single DIN or two DIN space. Most mobile radios mount under the dash, in a bracket attached to the dash or console, or under the seat. You will need to check the dimensions of the radio you buy before ordering it. You probably won’t be transmitting on more than one radio at a time so a single power supply should be fine as long as it has enough current capacity.

For my hf ham radio transceivers and accessories. I have one of those powerpole distribution panels that I plug into the power supply. I plug my handheld chargers into it rather than powering each one with its own wall wart. I also plug in my tuner and SWR/wattmeter, but that’s a very light load. I was using a 30 amp Samlex switch mode power supply, but the fan started going on even though there was almost no load and while I was watching the internal voltmeter swung down to 5 volts, even though the output voltage remained rock steady according to my fluke. This 50 amp linear supply should be acoustically quieter. I never detected any RF noise from my switcher on any band.

I just ordered an Astron 50 amp linear power supply. From Gigaparts or DX Engineering it’s $200 more than from Ham Radio Outlet.

Astron makes really good (but not inexpensive) power supplies and they have a line of different ones with radio enclosures. https://www.astroncorp.com/slim-line-w-housing

CTCSS/DCS tones on different brands of radios
SteveShannon replied to Lambing's topic in General Discussion
Exactly! -
I’ve never seen one. Even most ham radios designed to be used as base stations require an external power supply.
-
The band used to include 220-222 MHz. That portion was lost to ham radio so UPS could have it. They never did.

Nothing you said has been offensive but I don’t understand why you don’t want to be an eggplant. -

Someone woke up on the wrong side of the bed. I hope you have a better day tomorrow. -

Yes, for some people. I don’t know if it requires a premium membership or that you have risen to a certain rank.
-
If you already have the cord (others have provided link) you should be able to connect it to any power supply sold for use with two way radios. A switch mode power supply will be less expensive, lighter, and smaller. A linear power supply will be heavier and bigger but many people like them for their longevity.

Baofeng gm15pro shows long antenna included, but not shipped?
SteveShannon replied to a topic in Guest Forum
Normally there’s a product box that fits the white plastic liner better. See how there’s a sizable gap between the plastic liner and the brown cardboard box? It looks like whoever shipped that to you removed the product box ( which is made of white tagboard and colorfully printed and fits inside the brown cardboard shipping container) and put the white liner with the radio in it and the plastic wrap directly into the corrugated cardboard shipping box. That may have been done to provide room around the inside of the shipping box for your longer antenna. -
Baofeng gm15pro shows long antenna included, but not shipped?
SteveShannon replied to a topic in Guest Forum
Getting back to the original post, it’s truly unimportant whether it was an original Baofeng box, an oversized shipping box, or something else entirely.. What’s important is that the OP must contact the vendor to get the antenna that was advertised. -

Terri, that’s an impressive stack of uniformly sized boxes. At least through BTech, it appears that Baofeng has a standard single radio box. That makes sense from a cost standpoint. I wouldn’t want either a small rattler or a long antenna bent nearly double in one of those boxes. Randy, let Terri be. She’s one of the good ones we really want to keep. She doesn’t come here and act like one of the several resident assholes we’ve had. She backs up her points with facts, figures, and photos. I have no idea whether the boxes you’ve experienced are differently printed but same size (as her photos indicate happens) or whether you have received 34 different sizes, but the argument isn’t really important enough to drive one of the good ones away. I don’t doubt that some sellers bend 15” flexible antennas to fit the boxes, but one time it happened to me the antenna took on a bit of a permanent arch. A friend gifted me a Wouxun and couldn’t find the original rubber duck so he bent his 15” antenna into the outer shipping box and sent it instead. The other time I received a 15” antenna it was in my packaged with my very first Baofeng, in a larger box with a “covert earpiece”, a PTT microphone, a charger, etc. some of the pieces, like the antenna, were marked TidRadio, and others said Baofeng. Perhaps some value added reseller put together a special package of accessories as so many on the Amazon Marketplace do. In any case, it’s not important enough to berate people over. -
Thank @OffRoaderX, he made the video.
-
YouTube, look for videos from the Notarubicon channel. One specifically describes configuring a radio for a repeater.
-
Mine can, but it’s an older model.
-
It hadn’t been nullified at the time of the video and banter. The FCC really should have made at least an attempt to announce it.

Question re: grounding for lightning protection
SteveShannon replied to WRTC928's question in Technical Discussion
Portable devices typically are not grounded.
