Amateur radio

[capreycorn]

that is a challenge using those radios..I still clearly remember how bad our radios worked in the army.these "old" radios would pick up nothing or just garbled rubbish from the police band (we weren`t even close to the police frequency!).we had to use mobile phones during field exercises..heard, that coalition troops sometimes had similar problems.

what are the chances, that satellite communication would still work?

Stick with ham radio. In the event of a war. Satellites are high priority targets.

Hi Waterman,

The test fee is now $14 not $6.

now, with a possble nuclear war scenario...
won`t a ham radio "go down" like everything else due to EMP?
shielding a device is not that easy...it was a long time ago , but i remember reading, that lots of copper (a net/foil) is needed to shield an electronic device it shall also not touch the device to be shielded and in addition to that, the shield must be very well grounded...
i`m wondering if the soviets have old EMP hardened radios for sale..

plus a good car for the day after EMP would be a old soviet built car ...or the east german (DDR) "trabant" (guess Bono of U2 owns one of those old commie cars)


ps: (DDR formerly also known as "east germany" would have had its national holiday on october 7 - the founding day of the DDR)

Hi capreycorn,

Yes, unprotected a solid state device will likely be non-functional after EMP.
However shielding a device is easy .... it will probably not be easy to foresee the EMP coming ...

If you have a metal file cabinet just put in there ... (mind the isolation from the cabinet !)
Wrap it e.g. in a towel and then in tinfoil ...
If you really are in a hurry ... try the refrigerator !
(I am not sure if the door is electrically connected to the casing but your chances are better than nothing).

Most radio sets are made with a metal casing. If you have everything disconnected (microphone/antenna/power cord)
there might be a fair chance it will be protected by itself. Grounding is not needed and perhaps not even wise since
you connect a cable to it again ...

Cheers

thanks for the feedback..i like the "fridge idea"

in one of your first posts (thread page 1) you mention grounding the case could be of help.....

i think that grounding might be good (grounding very deep into the earth) using several cables to ground "the shield" ...

but I`m no expert..
.

i think we need an EMP expert here!

Finally got my ham radio set up and going.

If there are any hams here that would like to try a sched at some point on HF, then by all means just ask.

I am in the UK, and use sideband most of the time as I am still learning cw.
