I don't think they are who you are thinking of.  They advertise crystals
for 426.25, 434.0, and 439.25.  They do not mention 436 MHz.

By the way, being on 436 should be little trouble to the weak signal
activity on 432.1.

p.s.  The only bad think I can think of to say about them is that
      they still ship with UPS.
