I think the F1M 'Pete' only had an operational scout radius of ~150* nm. The E13A 'Jake' was able to scout to a radius of ~350 nm, and the A6M2-N 'Rufe' to a radius of ~450 nm. I can not say as to the specific radio capabilities, but the combination of the altitude of the aircraft when transmitting, the broadcast power and frequency/wave-length of the aircraft radio, the height/length of the ship's receiving antenna, and the sensitivity/gain/SNR of the ship's radio system, would have to allow 'reliable' communication at these ranges.
*[edit: fixed typo for radius of F1M 'Pete' to 150 instead of 250]
