DR 135E
DR-135E
EINDE VOORRAAD, EINDE PRODUCTIE..... werd vervangen door DR 138
De DR-135 is voorzien van een 7 karakter display, 3 power settings, wide en narrow FM modes, en groot koelblok voor continu gebruik.
(afgebeelde foto is met optionele EMS57 DTMF-microfoon)
Packet-radio en APRS voorbereid dmv gebruik met de EJ-41U digital comminications print.
Aan de achterkant is een SUB-D 9-pin connector tbv computer communicatie. (packet/aprs enz..)
