unusual question: planning on using a V1 to look for drones using airborne radar for mapping

AS far as you guys know, is this picture accurate:
http://coruxgroup.com/go/o.MR2/aw11/photos/detector/05rj11pins.jpg

I remember reading somewhere that the V1 uses more than just the two leads, but I don't remember where I read it, and I can't find the reference again.
I bought a V1 for $150 off Craigslist (s/n 9328430516; ineligible for an update per the V1 website) . It's missing a power cord, but that's not a big deal. I'll fab up a power cord. I just need to know which lead(s) on the RJ-11 connector should be 12V+ and which one(s) should be ground. I'm not using it in the car, it's a static application, so I don't need a car power cord. It will be attached to a 12V battery pack.

I'd call Valentine but I doubt they would want to tell me how to hack their product instead of buying a power cord from them. I just like tinkering, and if I have to cut up a phone cable anyway, I might as well use the one I have laying around.

Where’s the unusual question about airborne radar?

Like (almost?) all other RJ11 detectors, the V1 uses only those two inside pins for power. The rest aren’t used for power.

Data + is carried on one of the outer pins. It shares the same ground as power.

Where’s the unusual question about airborne radar?
Sorry, should have made that more explicit. I am trying to get to the bottom of the Colorado/Kansas/Nebraska drone mystery. There have been credible reports of commercial size drones performing flight maneuvers consistent with aerial mapping, and setting off radar detectors.

SecTrans Chao (head of the FAA reports to her) told a Yahoo! business reporter that they don't know what the drones are or who is running them. She didn't say they don't exist. Colorado Fire Chief Morgan said in an internal email, relative to their public pronouncements, "we're being as fuzzy as we can and still be honest". Colorado Sheriffs were asking their residents to report unusual vehicles that may be supporting the drones.

Colorado Department of Public Safety was unable to explain about half of the 100 or so sightings they looked at. Some of these unexplained sightings were from LE. This was spun to mean that the reports were unsubstantiated, in other words, not credible. It appears there is a 'credibility gap' in the official explanations.

The uncertainty leaves room for debunking that isn't really debunking, it's just assertions, without evidence, that nothing unusual happened.

Following a closed door briefing (media barred) the Sheriffs all said they were not going to be involved with the drones issue.

Airborne mapping radar uses Ka band. I'm just curious if I can get some data that would explain the sightings, or if I can show conclusively that the sightings are all normal aerospace activity (misidentified satellites, airliners, General or military aviation, etc.)

I intend to use a V1, aim it at the supposed drones and see if I get an alarm. Aim it away and see if the alarm changes. Wait for the aircraft to leave and see if the alarm disappears. It's just another data point. So the V1 will not be mounted in my car, I'll have it outside.

That's what I thought too Barry, but he has a pre ESP unit.
ESP and JBV1 would be perfect for that job, if PAWS applies to drones.

You may need to make sure you go through the programming settings of the V1 and turn off the Ka guard settings so it will show those. Do you know what frequency the transmitter on the drones uses?

Thanks LouG. I didn't realize from the info in beastmodehunter's opening post that his was a pre-ESP model.

drone frequencies? I don't know what frequencies my friend's radar detector picks up. I know K, Ku, and Ka are possible - some airborne radars use those bands. I have yet to use mine.

He said ineligible for update, I'm assuming it's very old.

Regarding radar mapping, I’ve read books on the US World War II B-17s and how they used air to ground radar to make bombing runs and find their targets when clouds obscured the ground and the Norden bombsight in the nose could not be used.

So did the Poms for night bombing. They had radio location and radar called Gee and H2S. It was very crude and suited to area bombing only.

What was more interesting is that they and the Germans developed the first radar detectors. Tail warning radar detection.
