Professional commercial multi-kW MF--HF transmitters (tube, from the 70s--80s) can be had for almost free (some will donate for free---just pay freight shipping, which isn't that expensive---I've had my microwave klystron transmitter units, each one of mass = 1,200 lb., shipped via freight, naturally, in addition to the other microwave transmitters that I have). And for the decommissioning operations that aren't into donating and wish to get paid for the scrap cost, just have them mass the unit and pay whatever the metal scrapper would've paid them. And regarding the power bill, of course it need not be operating 24/7---just come up with a rational schedule (taking into account tube figures, propagation modelling, and the budget), publish it on the website, and enter it into one's SCADA software. I would've done it myself (multiple transmitters, in fact, not just one HF frequency), but I'm doing METI, satellite TT&C, and Internet infrastructure (HF--mm wave) instead, all nonprofit, and moreover am permanently relocating out of the nation. -Ruslan -- Ruslan Nabioullin Wittgenstein Laboratories [email protected] (508) 523-8535 50 Louise Dr. Hollis, NH 03049 _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
