This RL Drake AUX-7 Module Set for WARC Bands 12 & 17 Meters, consists of two modules for installation on the AUX-7 Board in the Drake TR-7, TR-7A, R-7, and R-7A radios.For those who have the installed AUX7 board in their TR7 or R7 you can now fill the WARC Bands void by installing this set of two modules. This avoids having to use the UP and DOWN buttons on the radio to cycle through the 500KHz band segments outside the normal band selections. (This cumbersome method requires modification)Each band module is made from high impact glass-filled nylon and fully enclosed. Pins are GOLD plated to prevent corrosion in even the most adverse environments. Modules are built per order and are tested on a custom built fixture that places the modules under the same operating parameters as in the Drake 7-Line equipment. Simple to InstallInstallation is straight forward and every attempt was made for ease of installation. The user must have an AUX7 board and the original Drake manual on its removal and installation. I will supply an instruction manual which explains how to install the modules onto the AUX7 board. These modules for the WARC Bands cover 18.0 - 18.5 MHz TR7 or R7 (17M Band) and 24.5 - 25.0 MHz TR7 or R7 (12M Band) are enabled for full transmit functionality on the TR7 transceiver.
