The FCC here in the USA does not require having a rig that meets state of the art specs, either for Amateur or many commercial applications.
When checking shipboard radio installations in preparation for their annual FCC inspections, I used a variety of different specs the gear had to meet based on its year of manufacture. Older gear had a lot looser specs than the newer stuff. The same is true for Ham rigs. It's perfectly okay to run an old Heathkit AT-1 or a 1930's homebrew rig with cathode keying today as it was back then, even though the keying bandwidth will be substantially greater than modern rigs. The bottom line is to make sure the rig you have is being operated to produce the cleanest signal its design allows in the mode of operation being used. That's why double-sideband amplitude modulation is still legal even though it requires more than twice the spectrum of an SSB signal and CW is still allowed even though SSB and the various digital modes provide the same information in yet smaller bandwidths. 73, Ron AC7AC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
