PSR 1822–09 is a nearby galactic disk pulsar with a typical .769 s period. Its large period derivative indicates a young timing age of 250,000 yrs and a strong estimated surface magnetic field of 6.4 × 1012 G. We have observed this pulsar at frequencies around 1700 MHz and 2650 MHz. The mean pulse profile at these frequencies consists of a double peaked main pulse with two dissimilar components and a weak interpulse 185° of pulse longitude after the main pulse second component. The interpulse is detected in both frequency ranges, and the main pulse - interpulse separation does not change between these frequencies and the low frequencies around 327 MHz where the interpulse was discovered by Cady and Ritchings (1977).
