question on antenna configuration
[edit]The antenna description in the article says that the SCR-270 antenna contained 36 dipoles (and reflectors) arranged in three bays, each four wide by three high. I can find no pictures or text descriptions that confirm this. All SCR-270 and SCR-271 pictures that I have seen show a 32 dipole array, either eight wide by four high (fixed configuration), or four wide by eight high (mobile configuration). Anyone have some data on a 36-dipole configuration? Ekconklin (talk) 20:29, 27 November 2008 (UTC)

[edit]I am contacting Don Helgeson by e-mail (and possibly by phone) to confirm that this text is indeed posted by him. From this webpage I concluded that the author of this article is indeed Don; it remains only to confirm that he is the poster as well, not someone who was ripping him off.

addishinal edditing required

I am the Don Helgeson ([email protected] - Gleaner&Scrounger for "Electrohist & RadarHist News Letters) that wrote the SCR-270 radar piece and it would be a iseful addition to the History of Radar article in my (addmittdly biased) estimation.
How do I get a Spell-Checker to work here?
Best Regards, DonH
rewrite needed and completed
[edit]Regardless of the identity of the original article, the article itself was inaccurate historically, misleading, needlessly technical and generally poorly writen. Hopefully this version corrects at least some of this. Maury 18:58, 23 December 2005 (UTC)
On the history of the Opana point radar and its role in Pearl Harbor. I am intending to add several corrections to the articles posted. First the Operator at Opana point was not in training and was a fully qualified operator and that the plotter was in training though Elliot did recieve a medal for reporting the raid.
Second and a more important concept is that the Opana site, and three other Oahu radar SCR 270 sites and the command center were closed around breakfast because a fuel conservation order, (apparently the generator used a lot of gasoline ), was in place limiting the generator use to the hours between dawn and dusk.( apparently prime attack times) All four sites on Oahu should have shut down and but at Opana the truck was late for breakfast and they continued to operate.
Third, all the radar installations on the islands at the time were SCR 270 mobile units.
this information comes from my father Warrant Officer Robert S. McMurtrie Army Ret. stationed at Schofield and associated with Opana, before, during and after the Dec 7, 1941. attack. Doug mcmurtrie 01:18, 3 September 2007 (UTC)

- "Even if the correct bearing to the fleet was delivered, and the B-17's had survived the attack, it is unlikely that the B-17's would have been able to locate the Japanese fleet, much less survive their fighter defenses."
as irrelevant. The B-17s would have been perfectly able to detect the Kido Butai, & had at least some chance of surviving (Zeros found them tough targets), but were a) incapable of actually hitting ships at sea & b) not part of the Pacific Fleet... I also deleted
- "According to Bergquist during questioning by the Roberts Commission, if the air bases had been on alert the air crews were capable of launching planes within three minutes of an order[3]. Had the value of the SCR-270s been understood, the bases easily could have had all available squadrons in the air prior to the arrival of the Japanese planes over Pearl Harbor.
because it gives an extremly inaccurate picture of AAF AD readiness. "capable of launching planes within three minutes"? Fat chance. The a/c had their guns unloaded, some removed, & IIRC, they were mostly unfuelled. This could not be accomplished in the 50m or so before the first wave arrived. I also deleted
- "Another problem reported to the Roberts commission was that turf wars kept the radar units under the direct control of General Short, instead of the Army Air Corps's air defense units."
as inaccurate. They were under the control of the signal corps SO; AD answered to Short, too, don't forget.... TREKphiler hit me ♠ 12:48, 19 March 2009 (UTC)

[edit]this radar looks pretty much like a german pre war radar deleopment, named freya - named after the nordic godness that can look trough darkness any evidence this set is original US development ?--Gonzosft (talk) 17:15, 25 March 2009 (UTC)
False information
[edit]The claims about the Pearl Harbor unit under "SCR-270s Today" appear to be false. The cited source only says that the National Electronics Museum has an SCR-270, not that it has the Pearl Harbor unit. The article on this page debunks the whole story: http://artsandscience.usask.ca/news/magazine/Spring_2016/campus-myths.php 128.233.6.31 (talk) 17:35, 5 July 2016 (UTC)CQP
