Please read before posting Save 'I Just Got Licensed' threads for Wed thread. Welcome to Reddit's own amateur (ham) radio club. If you are wondering what Amateur Radio is about, it's basically a two way radio service where licensed operators throughout the world experiment and communicate with each other on frequencies reserved for license holders. All topics relating to the hobby are welcome here, from purchasing and building equipment, to operating techniques and activities, and everything in between.

In the US, new licenses take up two weeks to process. Longer if there is a federal holiday. Varies depending on sponsoring VEC (ARRL, Laurel). All Baofeng related questions should be posted at.

Apparently the ARRL set up a Spectrum analyzer at Dayton the last few years and offered to test attendee HT's for spurious emissions.

FCC Part §97.307:(e) The mean power of any spurious emission from a station transmitter or external RF power amplifier transmitting on a frequency between 30-225 MHz must be at least 60 dB below the mean power of the fundamental. For a transmitter having a mean power of 25 W or less, the mean power of any spurious emission supplied to the antenna transmission line must not exceed 25 µW and must be at least 40 dB below the mean power of the fundamental emission, but need not be reduced below the power of 10 µW.

A transmitter built before April 15, 1977, or first marketed before January 1, 1978, is exempt from this requirement.At Dayton this year, only 25% of the Baofengs that were tested, complied with Part 97. 21% of Baofengs were borderline, and 54% of Baofengs were non compliant. 86% of Wauxon's were compliant and 14% of Wauxon's were not compliant. Yaesu, Icom, Kenwood, and Connect Systems: 100% were compliant with the Part 97 standards.The ARRL concluded that many of the radios that did not comply, would cause harmful interference with other radio services.The article is on page 74 & 75 of the November QST. I wouldn't really consider the testing environment at hara to give conclusive results. Tons of RF flying around.

Mostly emitted from Hat Antennas.True, for the fairness, they did test other manufacturers' radio in the same environment and does show significant difference in the result, too. (You could call that 'control' for the experiment, if you will.)I agree that such environment is not ideal place to get conclusive results, however, it looks like, pattern do indicate some abnormality among those radios. So, no shock there: a crappy, inefficient antenna attenuates the spurs enough that the transmission system (transmitter plus feed plus antenna) falls within the spec.

'For a transmitter having a mean power of 25 W or less, the mean power of any spurious emission supplied to the antenna transmission line must not exceed 25 µW and must be at least 40 dB below the mean power of the fundamental emission, but need not be reduced below the power of 10 µW.' That part about 'supplied to the antenna transmission line' is important specifically because Amateurs - unlike many other Services- are authorized to modify their setup.for instance, change the crappy, inefficient antenna out with something less inefficient and less crappy (among other reasons).In short, you can put lipstick on a pig, but it is still a pig. Some hams care more about cost than signal qualityStudent and part time admin here. I have some expensive equipment (FT-817, matching tuner, TNC2) from the time before I went to university and worked full time.

I had to sell my TH-F7E to cover food expenses three years back. I'm somewhat back on my feet due to my part time job but not really in '300€ for a portable' country. I am not going to carry my FT-817 on my bike, I would never be able to replace it if anything happened to it. So, a shitty radio and an inefficent antenna are the best compromise for portable QSOs on 2m.Not all of us cheapskates are just cheap.

Some of us are so broke that the Baofeng is literally the only TRX we can afford. Some hams care more about cost than signal qualityYes, if you're too poor to be able to afford a Real Radio TM you should get the hell out of the hobby rather than use something that might not be 100% in compliance (even though the manufacturer claims it is) but there's no way to tell without using a spectrum analyzer. Which you should absolutely be required to own, and if you can't afford one, leave the hobby.And of course violators should be shot on sight by the FCC along with the GMRS scofflaws.

It's the only way to keep ham radio from descending into absolute anarchy!tl; dr - Damn no-code lids need to get off my lawn.

In order to increase awareness and ensure compliance with FCC regulations, the below FAQ is designed to help sign companies better understand these issues.For more information, please contact, Vice President of Advocacy, at (703) 797-0479.1. How can a sign company ensure that the digital signs it purchases from a manufacturer are FCC compliant?. The best ways to confirm that a digital sign is FCC-compliant are to (1) ensure that the equipment has the necessary compliance statement; (2) ask the “responsible party” (i.e., the manufacturer) to provide the testing data demonstrating compliance with the applicable emissions rules; and (3) ensure that the equipment has not been modified or changed in a way that causes the equipment to no longer meet the applicable equipment standards.

These elements are described in more detail below. By way of background, the FCC has two different equipment authorization regimes: (1) certification; and (2) a supplier’s declaration of conformity (“SDoC”).
