Ko te kaiwhakawhiti whatu tairitenga he ahua o te whakawhiti whatu, e te nuinga o te tango i te huringa auau tairitenga, te huringa amplitude, me te huringa wahanga ki te whakarereke i te riipene ataata, ororongo, raraunga me etahi atu tohu i runga i tetahi auau kawe, ka tukuna ma te whakawhiti i te whakawhiti whatu. . Ko te tohu whatu tuku: Ko te tohu whatu e tukuna ana e te kaitahuri whatu tairitenga he tohu whakahurihuri whatu tairitenga, e huri ana i te kaha kaha, te auau, me te wahanga o te tohu whatu me te kaha kaha, te auau, me te wahanga o te tohu kawe tairitenga whakauru. Na, he aha te transceiver whatu tairitenga? He aha nga painga me nga ngoikoretanga o nga kaiwhakawhiti whatu tairitenga? Me whai maiJHA TECHki te ako e pā ana ki te whakawhiti whatu tairitenga.

Ka whakamahia e te kaikawe whakaata orotika te hangarau whakarereke PFM ki te tuku tohu whakaahua i te waa tuuturu. Ko te mutunga tuku e mahi ana i te whakarereketanga PFM i runga i te tohu ataata tairitenga, katahi ka mahia te hurihanga hiko-ahua. I muri i te tukunga o te tohu whatu ki te pito whiwhi, ka mahia e ia te hurihanga whakaahua, katahi ka mahia te whakahekenga PFM hei whakaora i te tohu ataata. Na te whakamahinga o te hangarau whakarereke PFM, ka taea e tona tawhiti whakawhiti te 50Km neke atu ranei. Na roto i te whakamahinga o te hangarau whakahiatotanga wehenga roangaru, ka taea hoki te whakaatu i nga tohu e rua o te ahua me nga tohu raraunga i runga i te muka whatu kotahi ki te whakatutuki i nga hiahia o nga kaupapa aroturuki.
