wouxum quanchen et autre a tres bas prix ,,,apres plusieurs recherche je me suis appercu que ces appareil sont illégal au Canada ??
En tous cas, un article récent de l'ARRL * donne les résultats de tests en labo du Wouxun KG-UV2D et du KG-UVD1P; on y démontre graphiques à l'appui que ces deux rigs rencontrent les exigences légales du FCC.
Wouxun (pronounced "Oh Sheng" **) was granted FCC certification for the KG-UVD1P under Part 90 rules for commercial radios, clearing the way for use in the amateur bands. Ça m'étonnerait que ce ne soit pas la même chose (éventuellement) pour Industrie Canada. C'est pour cette raison qu'il est pertinent de consulter la règlementation américaine.

http://www.wouxun.us/content.php?content_id=1005PS: Ceci n'entraine pas que tous les appareils Wouxun ont reçu l'accord (ou l'absolution inconditionelle ;-) ) du FCC. Tout dépend des caractéristiques des appareils en question. Ceux vendus par Wouxun US respecteraient les textes et exigences de la législation américaine. Dans les achats en ligne (eBay ou autres), il est difficile de voir si c'est le cas. Concernant la législation US, on peut lire ceci
de QST:
Is it legal?
The FCC doesn't require equipment authorization for any "Amateur Radio" transmitter to be operated under Part 97, except those that incorporate scanning receivers, which require a grant of certification. If an Amateur Radio transmitter also includes frequencies allocated to other services, and if the device is intended to operate in those other services, as well as the Amateur Service, then the transmitter must be certified for all non-Part 97 radio services for which it is intended to operate. The FCC uses the term "intended to operate" as being equivalent to "capable of operation".
Wouxun is able to legally market a device that operates in the bands specified and that has a scanning receiver, because it has a certification grant (for Part 90 operation) which satisfies the certification requirement with respect to the scanning receiver. It can be operated by Part 97 licensees and by Part 90 licensees in their respective bands.
Wouxun US choose to limit the frequency range of the amateur version of the device to ham bands only. Restricting the frequency range of the device to ham bands only is okay as a Class 1 permissive change (without recertification) as long as the means for restricting the frequency range in the amateur version of the device is not done with hardware changes and without any denigration of the characteristics of the device as reported to the FCC. Wouxun US presumably wants to make sure that Part 97 licensees do not operate on Part 90 channels, and vice-versa.It is a good practice for them to market the ham band only version to hams, and to market the part 90 band only version to Part 90 licensees. Good fences make good neighbors. Le texte légal "Part 97"' concerne la radioamateur et le "Part 90" le
