This appears to be a straight advertisement for the website in question. While I personally find the site somewhat interesting and amusing, it's certainly not encyclopedic, and in any event has only tangential relevance to CONELRAD itself. If any Wikipedians think the advert is useful, feel free to explain why on this talk page. -- Quuxplusone 6 July 2005 20:30 (UTC)
Does anyone know the meaning of the phrase, "(City's Civil Defense Sirens 30)" in the introductory paragraph? It was added in the edit of <21:44, 3 March 2007 Newsandrumor>. It seems to be a related to CONELRAD's replacement by the Emergency Broadcast System. However, as now written, it is unintelligible to me; a citation or explanation is needed. -rich < Rich Janis 02:32, 12 May 2007 (UTC)>

I've removed a Youtube link to a supposed "Conelrad simulation". It's not an actual CONELRAD test nor is it an even faintly accurate simulation. The creator seems to have adapted a 1980s EBS script for CONELRAD instead of searching for the actual CONELRAD script, which from what I recall was very different. -- NellieBly ( talk) 07:59, 23 March 2008 (UTC)
I've come across a couple of different videos that, in my judgement, follow pretty closely what an actual CONELRAD alert would look like. Here are the links if you want to add them:

I don't understand the following statement from the article: Beginning in 1957, operating U.S. amateur radio stations were required to verify at least once every 10 minutes that a normal broadcast station was on the air. If not, the amateurs were required to stop transmitting. Several companies marketed special receivers that would sound an alarm and automatically deactivate the amateur's transmitter when the monitored broadcast station went off the air.
Why were they required to stop transmitting, and what does it have to do with CONELRAD? —Preceding unsigned comment added by Worldruler20 ( talk • contribs) 10:45, 9 March 2009 (UTC)
do not mention CONELRAD at all. 68.229.214.195 ( talk) 20:49, 21 May 2018 (UTC)
Any particular reason for the choice of 640 and 1240 KHz frequencies ? Would having the frequencies closer together have made more sense (less panicked knob twiddling in an emergency) ? Were there similar arrangements for Canadian or Mexican radio ? And did anyone suggest a third frequency for non-key stations in case the local "key station" was rendered inoperable ? 86.161.110.58 ( talk) 17:56, 12 July 2018 (UTC)
https://www.americanradiohistory.com/Archive-NAB-Engineering/NAB-5th-Edition/Section-8-NAB-Engineering-Fifth-Edition-8.pdf starting at page 121 in the PDF, contains a very detailed technical article about CONELRAD, including the pseudo-synchronous-sequential mode of operation.
