    Chip & Rege - knock off the endless barbs. Debate is fine - but all the personal barbs at each other are getting near the line and starting to poison the thread.

    It's otherwise an interesting discussion that is on the way to being locked.

    Thanks!

    Connect a KW amp output directly to another transceiver.

    What happens?

    You can do a lot of damage with 1000 watts...

    Video was UN-inspiring, if they knew the significance of the equipment they were flying their drones around then there could of been some good shots of the feeders, dipoles and other gear. Reasonable effort but typical of dumb down tech users. Sorry for the alternative response but they missed a perfect opportunity to gain knowledge but instead seeked personal thrills over knowledge. Very typical of what the education system produces.

    My father W7VQH sk always said "It's all in the antenna" Looks to be the case at the DUGA site. Feed lines look a little small for all that power stated. King sized fractal maybe??

    Would be fun to load into it....5-9

    Interesting, WA6VVC.

    No. It is called an Antenna Array.

    Where were their animal experiments - didn't they do animal experiments first? Even the Soviets had 'bean counters' to judge the 'level of efficacy' when their rubles were being spent ...

    I doubt very much the 'ladderlines' (if that's what they are)were the original feeds. Certainly they would take relatively little power for the system as it was, in either mode.

    What ARE you talking about?

    Why is there a deviation to biologics? I don't get it.

    Indeed. The "RF as a weapon" idea has long been hindered by inverse-square, among other considerations. To bank-shot weaponized RF off the ionosphere is definitely in the neighborhood of science fiction. When you look at how much energy it takes to make an effective EMP at a distance of just a few hundred miles above a target, there's no way Duga could do similar damage, no matter how big the Chernobyl plant might have been.

    There is no doubt that the Duga station would have a made a smashing good jamming transmitter, however. There are many witnesses to that use of the station. ;)

    What is it, coax or waveguide?

    You do understand "waveguide" is simply parallel wire transmission Line supported by a infinite number of shorted quarter wavelength stubs?

    In other words a pipe with nothing inside it?

    What?

    Waveguide beyond cutoff?

    Or a box with many many in-bypassed wires in and out.

    Can you say TEMPEST?

    https://en.m.wikipedia.org/wiki/TEMPEST

    In any case there was never such a device on Madagascar.

    I guess its fun to ignore the math...

    OK, enjoy. No biggie to me if you want to impose a belief system.

    On a related notes, I am taking bets on how long it will take for the DUGA to fall down...

    50 years?

    150 years?

    500 years?

    I wondered much the same thing... in looking at lots of photos clearly showing lots of rust, the fact the array was begun in 1972 and has not been maintained since the Chernobyl disaster in 1986 (likely not much maintained for years prior to that even), and considering its own sheer massive weight and wind load, I'd say 50 years more, tops. Probably less IMO.

    Just my guess...
