Proto jsem nev\u00e1hal a hned druh\u00fd den po setk\u00e1n\u00ed jsem sedl k internetu a zacal hledat jak toto roz\u0161\u00edren\u00ed udelat. Nalezl jsem nekolik n\u00e1vodu, jeden dokonce na ofici\u00e1ln\u00edm serveru firmy KENWOOD, ale bohuzel v\u0161echny se zab\u00fdvali pouze s \u00fapravami americk\u00e9 verze tohoto modelu tedy TH-G71A. Nicm\u00e9ne jsem se rozhodl, ze to nebude takov\u00fd rozd\u00edl a rucku jsem upravil podle n\u00e1vodu na verzi a A nakonci. K \u00faprave jsem pouzil napr\u00edklad tuto verzi nalezenou na internetu. Bohuzel po proveden\u00ed \u00fapravy se nic zvl\u00e1\u0161tn\u00edho krome vymaz\u00e1n\u00ed pamet\u00ed nestalo a tak jsem musel zac\u00edt experimentovat.

Dal\u0161\u00ed nepr\u00edjemnou vlastnost\u00ed je, ze homologace vztahuj\u00edc\u00ed se na toto zar\u00edzen\u00ed tak\u00e9 pad\u00e1, protoze byla prov\u00e1dena pouze v p\u00e1smu 144 a 432 MHz. Tak\u00e9 bych v\u00e1s chtel poprosit, aby jste nevys\u00edlali mimo amat\u00e9rsk\u00e9 p\u00e1smo a zbytecne tak neprodukovali ru\u0161en\u00ed v p\u00e1smech, kter\u00e9 mohou vyuz\u00edvat profesion\u00e1ln\u00ed sluzby jako napr\u00edklad Eurotel apod. A v neposledn\u00ed rade je nepr\u00edjemn\u00e9 to, ze se z va\u0161\u00ed verze E stane A, tedy zapomene generovat t\u00f3n 1750 Hz na nahazov\u00e1n\u00ed prevadecu a tak\u00e9 bude pri automatick\u00e9m prep\u00edn\u00e1n\u00ed odskoku reagovat jako by byl v USA, teda necek\u00e1 prevadece v p\u00e1smu 145,600 &#8211; 145,800 MHz.
