well, thats a toughie. a double radar wouldbe like 21122112 or something like that. haveing 2 4 digit repeaters is similar, but not the same. On Ebay, if you pitch it right, someone might buy it. Not to kick it while its down, but i do have some notes in my collection like that -- i think they are neat, if not worth any premium.

 

Thanks, Daggar. I guess the other one I got a few wks back makes your catagory 54455445

 

yep

 

thats really just a note with 2 different palindromes as a serial number.
I think, as stated, a "double radar" would be 12211221.

 

Yup, thanks Magman
