Communication Consoles

“McGee Boxes” - Designed to Meet Your Small-Console Communications Requirements

The “McGee Box” is configured to work for a range of applications through the use of standard protocols such as Simplex Signaling intercom, DTMF Signaling intercom, Tone Radio Control, Tone Radio Control with DTMF signaling, DC Radio Control, Hands-Free Intercom, Multi-Line Intercom or Audio Monitor.

FEATURES INCLUDE:

Modular line connectors (RJ-45)
Circuit board jumpers for configuration of the following parameters:

2-Wire or 4-Wire line
600 Ohm or Hi-Z termination
DC Blocking

Automatic level circuits in transmit and receive circuits help keep audio levels constant while “downward expansion” minimizes line noise.
Audio power amp with short circuit and over-temp protection
TVS line protection
Cross Mute (ground), Auxiliary PTT contacts, and PTT foot switch contacts standard.
Choice of microphones: Electret microphone standard, gooseneck or desktop dynamic microphones optionally available

SPECIFICATIONS:

Construction: Heavy gauge, hard anodized aluminum base with painted steel upper panels.
Size: 6 7/8“ wide x 4 5/8” tall x 7 5/8” deep
Line Type: 2-wire and 4-wire, “0dBm” communication lines.
Receive Level: -20 to +12 dBm, with ALC knee set at -26dBm,
Transmit Level: -26 to +3 dBm into 600 Ohms
Speaker: 3 1/2 inch, heavy duty with water-resistant cone.
Audio Output: 1 Watt (Can be factory adjusted to 4 Watts upon request).
Power Supply: Nominal 12 VDC, current requirement varies with model, 2.1 mm jack with center positive, externally accessible fuse.
Line Connections: RJ45 connector on back panel.
Auxiliary connections via pluggable connector accessable from rear of unit. Aux. connections include PTT foot switch, ground cross mute and Aux. Relay contact. Aux. Relay contact is a 'Form A' contact, factory configurable to provide an isolated closure, a pull-to-ground or a pull-to-+12 VDC.
Available adjustments: Receive Sensitivity, Transmit Level and Microphone Sensitivity

Control And Radio Products

	14-99005V2 Radio DTMF Activator Radio activated control relay. 1-6 digit DTMF code, "Form C" contact output. Available in wall mounting and signal rack mounting versions. The "V2" format allows multiple operational modes to be built-in and they are user selectable.
	14-99005V2-AC1 Radio DTMF Activator, AC Powered Operationally similar to 14-99005V2, but powered by 117 VAC, enclosed in a NEMA-type box and provides 24 VDC output for powering auxillary equipment.
	17-95160 Remote Speaker Switch The 17-95160 Remote Speaker Switch enables interfacing of an internal speaker, external speaker and Remote Microphone (61-95039) to current Icom (e.g. F5061) and Kenwood (e.g. NX700) radios.
	61-95039A-V2 Remote Microphone Provides second transmitting location for a mobile 2-way radio. Typically used at the rear of a work truck. This model is normally provided with 30' of cable and the end-user terminates it to the 2-way radio as appropriate. Larry McGee Company provides hook-up instructions, but the customer must ensure the unit hook up is compatible with the configuration of the radio in use. This model can also be special-ordered with extra-long cable. Note: We are happy to announce that the DTMF microphone is once again available and shipments of the Remote Microphone have resumed!

Locomotive Products

Larry McGee Company manufactures a number of products for use on locomotives. They are specified by major railroads and are installed in new locomotives by major builders. They are also available for installation in existing locomotives

Radio Control Panels
Several models of Radio Control Panels are available, each filling different operational requirements.

	61-95014 Amplified Conductor's Panel and handset connector Built-in amplifier uses "handset audio" from popular locomotive radios.
	61-95015 Non-amplified Conductor's Panel with DTMF microphone Uses high-level audio from popular locomotive radios. Note: The Motorola HMN1037B Microphone is once again available, so the 61-95015 is shipping!
	61-95028 Conductor's Panel with DTMF touch pad and handset connector
	61-95035 Non-amplified Conductor's Panel with handset connector Similar to 61-95015, except substituting the handset/microphone connector for the built-in microphone.
	61-95045 Non-amplified Conductor's Panel, "compact"
	61-95046 Amplified Conductor's Panel with DTMF touch pad and handset connector (handset not included) Note: This product is available on special order and is subject to minimum quantities.
	61-95050 Speaker Panel with lighted DTMF panel, built-in microphone, handset connector, amplifier and water-resistant speaker.
	61-95053 Non-amplified Conductor's Panel, "compact". Similar to Model 61-95045. Equipped with a 16 Ohm speaker.
	86-14001 Summing Amplifier Hand held DTMFmicrophones are widely used on locomotives. Connecting two external DTMF microphones to some locomotive radios can result in low transmit levels. To remedy this situation, Larry McGee Company offers the Microphone Summing Amp. It is a “unity gain” amp, so that it does not change the microphone levels
