Apache Labs ANAN-10+ - Modular Microphone Connections

PTT plugs in adapter.
Note that JP6 has no jumpers by default, thereby disabling PTT.
Modular Microphone connections
Updated 09/07/2012
Hermes / ANAN-10+ SDR's have a 1/8" or 3.5mm stereo jack for microphone input and PTT. The following
instructions outline methods for interfacing common 8 Pin Modular microphones available from Kenwood, Yaesu
and others to Hermes / ANAN-10+. Since I don't have a Hermes / ANAN-10+ I am unable to test these
instructions with a working radio. Use at your own risk.
These instructions assume the user has properly installed and configured a PowerSDR version compatible with
Hermes and installed the appropriate Hermes firmware for this version.
WARNING:
The FPGA and other components on the Hermes PCB can be damaged by Electrostatic Discharge (ESD). When
handling the PCB, you should take ESD precautions (e.g. use a work bench with an antistatic mat on it and wear
a grounded wrist strap).
WARNING:
Remove DC power before opening housing to change jumpers. Failure to remove DC power could result in
damage to circuit boards.
Adapting some existing 8 pin modular Ham Microphones to Hermes 1/8" or 3.5mm stereo plugs without using a
soldering iron:
CalRad adapters:
CalRad ( http://www.calradstore.com/72-173.html ) makes several modular (RJ-45 or 8 pin Modular) to 8 pin
terminal block adapters which can be used to easily interface modular microphones to a 3.5mm / 1/8" stereo
plug required by Hermes / ANAN-10+
Cal Rad adapaters are also available at

The Calrad 72-173 Cat5/Cat6 solderless RJ-45 Female to Terminal block provides a very simple way to interface
a Stereo jack to a RJ45 modular connector.
The CalRad 72-173 has a terminal block with 8 screw terminals on one end and a female 8 pin modular or RJ45
jack on the other end. It is just a matter of connecting 3.5mm / 1/8" stereo plug wires to the Calrad adapter
using a small screw driver. No soldering required.
