The government's strategy of using radio to wage "psychological war fare" was particularly effective. Their opponents, who relied on the air force to deliver orders and distribute anti government propaganda leaflets around the country, could not contend with the immediacy of radio broadcasts. Nowhere else was this more clearly evidenced than in Nakhon Sawan and other areas in the north of the country where the use of radio played a crucial role in undermining royalist attempts to woo provincial troops to join in the rebellion.
