the most in depth study about emp effects i have seen including tests on cars, radios, and a lot of other items. interestingly they mention ham radio as one of the ways that the nation may overcome the communication failure. fyi: http://www.empcommission.org/reports.php

Thank You. This is an excellent document every ham should read! If we are going to be able to help in the aftermath of an EMP attack, we need to protect our equipment, but we have to do it before the EMP event happens!

Yes, Thanks for the link. Lots of good info. Most hams need to understand that an EMP event DOES have a very high chance of shutting down commercial AC power over very widespread areas. (Be prepared to operate on your battery/solar etc supply) However, As long as the typical ham station is well protected for lightning strikes, They have a very good chance of survival from EMP also. (EMP is like a lightning strike, But with faster rise time) Distance matters. IF you are more than a few hundred miles from the event, The need for special protection with stuff like a Faraday cage, etc should not really be needed. IF you are close enough that you DO need such protection, I suspect you may have bigger problems than just the EMP damage..........

One other thing you can do is to always have one spare transceiver totally disconnected from everything (power supply cables, antenna, computer control lines, microphone, etc) that is capable of operating off of a automobile battery. This good practice for lots of contingencies including EMP. For home use, that could be the radio in your Go Kit. For EOC and Red Cross Chapters, a spare transceiver could be so designated. This could be an older radio that has been replaced in daily use with a newer model. Just storing without connecting wires that might act as "antennas" should be sufficient. But if you want to be really sure, store the transceiver in a large metal tin, such as those that holiday pop corn is sold in. A spare coax and portable antenna should be also stored in case the regular ones also get damaged. One hint about spares of any type is that they should be tested regularly. 73 Gary, K2GW

This study highlights a new threat to our nation that is an inviting possibility to terrorist groups or rogue nations. I wrote an article for e-Ham about this in early June that you can find in the article list and it brought dozens of comments by other hams. A new 'best selling novel called "One Second After" takes on this topic with a fictional story of the results on a western NC town and the southeast region of our country after such an attack. It is scary. We as hams, do have capability to help our country after such an attack with critical communications, but we ourselfs must protect our own personal and familty survival and the survival of our ability to communicate. 73 K4YRK Dave Garner www.vhfhamradio.com

Dave I really enjoyed the article you wrote on EMP. I have been working to raise some red flags on the subject of EMP preparedness for the amateur radio community. I'm writing articles and giving a presentation to the local ham club on the subject. Would like to hear from you. Please email me at tech1906@yahoo.com Greg N0UJR

See also the excellent article on EMP in the November 2009 issue of QST by N2HX, a personal friend of mine and someone who's actually designed and installed EMP protected radio rooms in our state EOC. 73 Gary, K2GW
