FF Hydra is pretty close but not an exact match.

I also think it looks a lot like HTF Knockout No. 48 (or near that) that has been 'softened' to round off and blur the terminals.

too bad Elderkin is no longer available.

I'll go buy knockout and round the corners in illustrator.

This is Elderkin by Eric Olson / Process Type Foundry. For some reason it's not available on his site any longer. I purchased it before it was removed. Another alternative would be Ultramagnetic http://youworkforthem.com/product.php?sku=T0020 or Garage Gothic from Font Bureau http://www.fontbureau.com/fonts/GarageGothic. Mike's idea is also a good one, if you just need to set a headline or short bit of text you could try Trade Gothic Condensed Bold and round the corners in Illustrator or Freehand for a similar feel.

Eric Olson gave an explanation why he removed both
Process Grotesque and Elderkin in this thread. Process
Grotesque is being reworked, but I fear Elderkin's gone
the way of the dodo.
