Bottom line is this: if you don’t have to hear the poor quality of your own voice and you live in the middle of nowhere, a Baofeng can be a really slick option. The radios are cheap. They do transmit. They do make your voice heard. However, if you’re in an environment with a lot of RF floating around (think Vegas… think Washington… think Toronto… think New York), these radios are not great options. They frankly don’t have the guts to handle the mojo needed to avoid the noise.

For these reasons, I have chosen to ban Baofeng radios on my repeaters. This isn’t a Motorola elitism thing. This isn’t a, “You’re stupid for buying a Baofeng” game. I own Baofengs. I own my repeater and the users on my repeater all have similar audio levels. We’re all running ham or public safety grade gear. All of our rigs have similar audio circuitry that avoids the constant volume adjustments. I’m a professional organist. Simply put, I don’t need anymore workouts for my fingers.

Some will still argue that this is elitism. I argue that Baofengs go against the very reason why the F.C.C. allows ham radio to exist.

Simply put, these radios do not allow for “advancing skills in both the communication and technical phases of the art” (Part 97.1).

I assure you that my reasons are purely technical, and not a form of elitism.

Miten tavanomaiessa taajuusmoduloidussa lähetyksessä toistimella voi estää operoinnin juuri Baofeng-radioilla? Jos voi niin voisiko estää Wouxunin, Yaesun tai ICOM:nkin?

Ketjussa oli alempana estokeinona MDC tone. https://en.wikipedia.org/wiki/MDC-1200 . Toisin sanoen voidaan ryhtyä valtaamaan yleishyödykkeinä pidettyjä radioaaltoalueita valmistajakeskeisille standardeille. No tietenkin samalla taajuudella voisi ilman taajuuskoordinaatiota pitää muitakin toistimia ja sitten keskustella, kuka pysäköi oikein taajuusalueelle hieman kuin pysäköintialueelle.

Jotenkin tuntuu siltä, että CB-taustaisten lisäksi erityishuomiota saavat nyt myös Baofeng-käyttäjät.
