EMP
Those who were self-taught to the exclusion of sideband and sidetone
are no doubt unaware that in the event of a nuclear detonation that an EMP will melt the RF amps in their RXs because of the amount of power that their antennae will pick up? Anyway, in the light of the events in Paris last Friday, and previously the attack on the World Trade Centre on 11/9 the costly and unnecessary nuclear deterrent doesn't seem to be working awfully well, does it? |

The effects of an EMP have nothing to do with "sideband and sidetone", the damaga is not limited to RF amps, and a lot of the damage will be due to the amount of power that the internal circuitry will pick up. Anyway, in the light of the events in Paris last Friday, and previously the attack on the World Trade Centre on 11/9 the costly and unnecessary nuclear deterrent doesn't seem to be working awfully well, does it? As there has been no nuclear wars, I would say the "nuclear deterrent" has worked well. What nation state would you target for a nuclear reprisal? -- Jim Pennino |

No doubt there are those who will misunderstand, perhaps for the purpose of being obnoxiously argumentative, as does reay, the nub of my posts above, which is, that the threat to world peace does not come from nuclear bombs, but figuratively, from an armada of rowing boats crewed by those wearing the Osama Bin Liner and brandishing sickles and scimitars. With the outpouring of shock, hypocritically from Yankland, Britland and France who supply the international arms market which market supplied the AK47s and explosives, with "only" 250 people killed or wounded, who, now, in their right mind, would set off a nuclear bomb where the damage to people would be many thousands of times worse? So there is no purpose to the waste of money and resources inherent in nuclear bombs |

Well, seeing as how you are an expert in the analysis of newspaper stories, you might recall in the aftermath of the Falklands war it was mentioned, probably in one of the Sunday heavies, that at one of the early crisis meetings to discuss the UK's options the nuking of the city of Cordoba was mentioned. ISTR it being said that the idea was dropped when it was allegedly discovered that the US wouldn't give us the targeting codes.

We are way beyond that. In China the military resisted conflict with their own people. They brought in troops from the other side of the country who spoke a very different dialect. Here the troops would never meet the victims. Remotely operated weapons allow the military to fight anyone without knowing who they really are. Having rifles and "several thousand rounds" won't even let you defend yourself against other people for more than a few days, much less the military. Heck, a decent swat team would easily rout you out. Hand weapons are pointless these days for anything but killing someone in your own family. Like bringing a knife to a gun fight. -- Rick |

I don't pretend to be. When I was a Zoomy; low these many years ago; we were instructed to never open the case of any critical electronic item outside the shielded repair area. All of the Ground Radio Equipment was protected by two coaxial devices. The first covered stuff like lightning, snow static, etc.. The second one which was always at the antenna port of the radio was for EMP. The instructors alleged that if the equipment were installed in accordance with the technical manual's instructions and maintained that way it was safe from EMP. EMP protectors fail open. Each of the spares kits used in Strategic Air Command contained several of each type of protector. So what I want to know is were they misinformed? Was that all hokus pokus. We were certainly held to a high level of compliance with that training. Since many of my officers behaved like business executive trainees I gradually lost all respect for my immediate leadership but that didn't lead me to believe that it was all nonsense. I would truly appreciate answers based on actual testing or pear reviewed research rather than rules of thumb extended to unrelated issues. -- Tom Horne W3TDH On Wednesday, November 18, 2015 at 2:55:52 AM UTC-5, AndyW wrote: On 17/11/2015 18:30, gareth wrote: Those who were self-taught to the exclusion of sideband and sidetone are no doubt unaware that in the event of a nuclear detonation that an EMP will melt the RF amps in their RXs because of the amount of power that their antennae will pick up?

If you are close enough to a neutron bomb to experience the EMP, it is irrelevant as you will be dead anyway.

If you are close enough to a neutron bomb to experience the EMP, it is irrelevant as you will be dead anyway. That's been about my usual thinking.. I think the whole EMP deal is a wee tad bit overplayed. Seems to me, if bad enough to toast infrastructure, bad enough to toast carbon life forms. :| Or at the least, a severe pseudo sunburn.. Heck, a very close lightning strike is a fairly strong EMP event. Sometimes it causes mayhem, often times not. I still have old tube rigs if things came to that. But I don't fear for any of my modern rigs if they aren't hooked up. And I have more than one rig to increase the odds of one surviving. |
