Under what circumstances can an amateur radio operator reprogram a land mobile transmitter on behalf of another person for use on 2 metres?

When modifying or reprogramming a piece of commercial gear, such as a land mobile transmitter, to operate on amateur bands on behalf of another person, the crucial requirement is that the recipient is legally allowed to transmit on those frequencies. The 2-metre band is an amateur VHF band accessible to anyone with a standard Basic qualification. Therefore, the person receiving the reprogrammed radio simply needs to hold an Amateur Radio Operator Certificate. The recipient does not require an Advanced or Basic with Honours qualification just to use a radio on the 2-metre band, making the standard certificate the only necessary condition.
