Per quanto riguarda il Wouxun KG-UV8D, se dovessi mai comprartelo, verificate che sia la serie con la versione di firmware 1.05 (verificabile accendendo la radio con il tasto 3 premuto) e che abbia la batteria da 2600 mA/h, perchè le versioni precedenti (come la 1.02) soffrono di un fastidioso difetto in ricezione che purtroppo non può essere corretto in quanto il chip è del tipo "non riscrivibile" e non è possibile fare la modifica con il software di programmazione Chirp.
