Narrative:

While on a routine training flight; our helicopter had a near miss with an agricultural spraying helicopter. We announced position and intentions (on air to air frequency 123.02) prior to lifting off on a west heading. At approximately 200 ft AGL I heard an aircraft on 123.02 say 'I'm passing on your right; don't turn right.' I looked over my right shoulder at about the 5 o'clock position at about 300 ft horizontal and 20 ft below was a beige jet ranger west bound at approximately 150 ft AGL. I immediately altered course to the left and announced 'I've got you on my right' on 123.02.
