The more knowledgeable CB enthusiasts made a counter proposal to use a frequency around 220 MHz. This was immediately dismissed by the government who pointed out that it was a reserved military frequency band. It was subsequently discovered that the frequency had been unused since the Second World War. The government initially refused to relent and continued their insistence on legalising the 928 MHz band. The CB lobby continued to insist that any CB system had to use the 27 MHz band, be AM and a maximum output power of 4 watts (i.e. the US system).
