I doubt they use the same frequencies

Only useful if it can tell you the distance and bearing of the source, by the time you've figured that out it's probably easier to just install your own radar and see the other boat on that

Seems like a good idea maybe? A secondary/backup warning system?
I believe they do... Solo ocean racers use them.

I disagree with your premise here.

If I am short-handed offshore, a device that would alert me to the fact that it is being painted by radar would still be useful, even if it can't tell me from which direction or how far away. It would prompt me to wake up and look around, letting me know that there are other vessels in the vicinity!

That said, there is a device called the CARD (collision avoidance radar detector) that will tell you from what quadrant the radar signal came. I don't know if it is still being made, and some of the reports I've read about it have been rather mixed.

There are also devices on the market known as "Active Radar Target Enhancers" (or RTE's) that send out an amplified return signal when they sense an incoming radar signal. These devices are not directional, but the offer significantly improved radar cross section for many boats. They also serve as radar detectors, in that the have lights and/or sound signals indicating that they are working (have sensed incoming radar and are transmitting in response).

The two main players in this market seem to be the SeaMe device and the EchoMax Active-X.

If all you care about is "is someone sending radar waves out somewhere" then yes, a detector would be both simple and useful. The problem with all radar detectors is of course that you might get so many signals that you no longer pay any attention to it.
Enhancers are a good idea, as long as the person on the other end is actually watching their radar screen.
As for the CARD, as I said before, by the time you've got the equipment to figure something like that out, you could have probably got a radar of your own.

Could work, but with a 24mile radar, and a boat moving at 20knots, you're an hour of beeping from it

CARD does exactly that - detect other radar - had one but unfortunately you can't run your radar with the CARD also operating!
I opted for the radar verses the CARD.

Me too.

I am one of those pains in the a$$ who doesn't use electricity unless I must and thus I have an aversion to running radar just because it's there. I only run it when I need it.

So having a device that warns me that there is other radar in the area is enough to make me at least stick my head out and have a look or switch radar on if I can't see anything.

If there is that much shipping around there should be a permanent watch on deck anyway. The radar detector for me is a device that can be useful when you're properly out at sea and there is only a remote chance of meeting a ship, not when you're sailing amongst them.

Problem is I've never found one that can be depended on. Perhaps there is a market there?

One would expect such a device to have an OFF switch
