[Heathkit] AT-1 question

[Glen Zook]

Not really.  The field intensity of such signals are limited by FCC regulations.  Depending on the quality of the installation it is very easy to exceed those radiation limits.  It is very difficult for one to actually meet the requirements in field radiation without some stringent adherence to the quality of the equipment used.  It would require things like double shielded coaxial cable, a very "tight" dummy load, extreme shielding on the signal generator (in this case the AT-1), and so forth.

In the "real world", with all the "stuff" on the 11 meter band, probably no one would notice the signal.  However, since amateur radio has definitely been declared to be "self policing" the FCC has "assumed" that when an amateur radio operator publicly proposes a questionable operation then it is proper for other amateur radio operators to call it to attention that such operation would be illegal.

In my opinion, the person who started this thread would have been better served to just do it instead of calling it to everyone's attention.  By doing so just opens Pandora's box.

Practically, it isn't true. You can transmit anything you want into a dummy load, because excepting local leakage from the circuit, the design intent is for no emission to occur. That the FCC rule states that it is? Poor writing of the law, and impossible to enforce. Go ahead and transmit anything you want into a dummy load.
