     Referring now to  FIGS. 4 and 5 , the present embodiment of the invention includes a power supply subsystem for converting standard household 110/220 Volt alternating current into direct current and supplying it to first connector  38  as +24 Volt direct current. When control switch  50  is closed, a power supply converts alternating current power into direct current power at voltage levels required for HARRIS 117 radio  24 , i.e., +24 Volt direct current, and outputs the converted power to first connector  38  to allow for powering of HARRIS 117 radio  24  when installed or docked onto adapter assembly  10 . A suitable power supply is an ADA600F power supply manufactured by Cosel U.S.A. Inc located in San Jose, Calif. 
     Audio amplifier circuit is design with a five watt audio amplifier IC LM384N manufactured by National Semiconductor. Audio amplifier circuit acts as a power amplifier and relay for electrical signals generated by the HARRIS 117 radio handset when connected via microphone adapters  54 ,  55 . In this manner, communications exchanged through the handset can be heard via speaker and the volume amplifier circuit provides a power boost of 34 db maximum and operates off the +24 Volt input supply. The output is frequency limited by a low pass output filter. The output level is controlled via 20 k ohm resistor mounted on the front of the unit. 
     Inasmuch as power supply conversions and power switch wiring are well-known in the electrical arts, further discussion as to the electrical characteristics and properties of the internal power supplies for converting standard 110/220 volt AC into direct current will not be discussed as they are not necessary for a complete understanding of the invention herein described. 
     An adapter line connects the input/output of the HARRIS 117 radio  24  handset line to the adaptor assembly  10  and internal microphone electronic, and line connects radio handset with the adaptor assembly  10  to allow the transmission of voice communications (i.e. audio signals) to and from the handset. Additional electrical communications also occurs with the HARRIS 117 radio  24  via connectors  38  and  44  The combination of the HARRIS 117 radio  24 , and the adaptor  10  allow the HARRIS 117 radio  24  to operate while allowing others in the vicinity of the adaptor unit  10  to hear incoming and outgoing voice transmissions. The LS/671 Speaker connector located on the back of the unit is connected into this circuitry. This allows the LS/671 it broadcast the audio from the handset plugged into the front of the unit as well as the communications received into the radio. The speaker on the front of the base station will also broadcast the audio signals from the Handset plugged into the LS/671 External SINCGARS Speaker. 
     An alternative embodiment of the present invention is shown in  FIGS. 6 and 7 . This embodiment includes an assembly  80  that includes the ability to switch between AC power and DC power (20 v-30 v) seamlessly and automatically in the powering of tactical radios. This capability allows for the assembly  80  to be connected to both the AC grid and standard tactical batteries currently available throughout the military or to standard military DC vehicle power. Should the AC grid fail the unit automatically will switch over to the DC power without interruption of the power provided to the radio, power amplifiers, external speakers, etc. This switchover is fully automatic and requires no action by the operator. 
       FIG. 7  shows a rear view of the assembly  80  of this embodiment. The assembly  80  includes an AC Power (85-260 VAC) Connector  82  and two DC Power (18-32 VDC) Connectors  84 . The DC Connectors  84  allow for independent batteries (including vehicle batteries) to be attached to maintain radio power. This embodiment also provides two LS/671 speaker connections  86  in addition to two TOCNET control ports  88 . This embodiment of the assembly weighs approximately 20 pounds and has size dimensions of 13″×13.5″×17.5″. While the embodiment shown is configured to hold up to two SINCGARS RT-1523 model radios, other embodiments could be configured to hold other models of radios including: PRC-117; PRC-150 and PSC-5. 
     The assembly  80  in this embodiment may also provide a DC power output connector  90  using the standard power connector found in military vehicles. This output connector  90  can provide power for communications accessories such as the ITT Tactical Data Router (TDR) and FCBC2 (Force XXI Battle Command, Brigade and Below) Devices to operate on the assembly&#39;s power grid. Additionally, a global positioning system (GPS) unit may be connected (connector not shown) to and powered by the assembly  80 . 
     In an alternative embodiment shown in  FIG. 8 , the assembly  80  is sealed with gaskets from the exterior environment. The seal prevents dust and water from getting into the internal compartments of the assembly  80 . In this embodiment, the cooling fans along with their respective vent holes in the rear of the assembly  80  are removed. Instead, the assembly uses internal heat sinks (not shown) to provided cooling for the internal components. Additionally, the entire housing is sealed with gaskets that meet military specification (MILSPEC) standards. The gasket seal prevents electromagnetic interference (EMI) discharge. 
     Another embodiment of the present invention includes a Vehicle Adapter Amplifier (“VAA”) provides range extension and allows for rapid radio dismount capability. The SINCGARS VAA Vehicular Radio Mount AM-7239 is deployed into many vehicles and includes the interface for two SINCGARS RT-1523 Radios, one Remote Power Amplifier AM-7238 with an electrical connector, and an Internet Controller (INC) which is required for Digital Communications. The electrical connector for the Remote Power Amplifier is adapted and arranged for supplying power from at least two of the power supplies to the Radio Frequency Power Amplifier (“RFPA”) AM-7238 and a speaker supported by the base. 
     In this embodiment shown in  FIG. 9 , the top side  22  of the mount is adapted to simultaneously support the vehicular radio mount AM-7239 and the radio frequency power amplifier adjacent to one another. A connector is found on the left side of the front of the unit to provide the interface for the Radio Frequency Power Amplifier AM-7238. To that end, top side  22  includes a substantially flat, horizontal first platform for supporting the vehicular radio mount AM-7239 and a lower substantially flat horizontal second platform for supporting RFPA along with a higher, substantially flat, horizontal third platform for supporting a circular connector  92  to provide the ability of the unit to accommodate a LS/671 SINCGARS External Speaker with Microphone/Handset. 
     The backside of the mount includes an interface connector for digital control of the Radio Frequency Power Amplifier AM-7238 and a 28 VDC power out connector. Backside further includes slot access holes (as shown in  FIG. 7 ) to allow a flow of air through base as generated by a fan mounted in the bottom access panel of the unit. 
     In this alternative embodiment of the invention, the power supply subsystem converts standard household 110/220 Volt alternating current into direct current and supplies it to first connector as +28 Volt direct current and to second connector as +28 Volt current. When control switch is closed, a first power supply converts alternating current power into direct current power at voltage levels required for SINCGARS RT-1523 radio, i.e., +28 Volt direct current, and outputs the converted power to first connector to allow for powering of SINCGARS VAA Vehicular Radio Mount AM-7239 when installed or docked onto adapter assembly. A suitable power supply for first power supply is a ADA-750 power supply 
     A second power supply is provided for converting direct current power into direct current power for powering RFPA. Thus, when control switch is closed, second power supply converts 28 Volt direct current into +13 Volts direct current, +200 Volts direct current and +6.75 Volts direct current, which is directed to the second connector for powering RFPA. A portion of the +13 Volts direct current is used to supply power to an audio amplifier circuit. 
     The input/output of the SINCGARS RT-1523 radio voice communications are all accessed through a “Boat” connector. These signals are used to provide the input for the internal speaker, the Active Net LED and the LS-671 connectors on the top of the unit. The LS/671 Speaker connector located on the top of the unit is connected into this circuitry. This allows the LS/671 it broadcast the audio from the handset plugged into the front of the unit as well as the communications received into the radio. The speaker on the front of the base station will also broadcast the audio signals from the Handset plugged into the LS/671 External SINCGARS Speaker. Under normal radio operations the LS/671 External Speaker requires the Radio to be placed in a remote mode for operations. As this unit is primarily for fixed site operations where the external speaker is used to monitor radio communications in a commander&#39;s office this interface does not require the radio to be placed in Remote operation mode but allows the handset to be operated at the radio and the LS/671 Speaker and Handset. This embodiment also includes two light emitting diodes which indicates when a given radio is active to enable the radio operator to identify which radio is in operation when multiple radios are installed in one location. 
     The placement of the power amplifier minimizes the overall footprint of the unit while staggering the placement of the second power supply to promote cooling of the power amplifier mounted in the VAA by insuring the exposure of the power amplifier&#39;s cooling fins to the air.

     Another embodiment of the present invention is a knob clamp lock that secures a radio on the platform by preventing access to a knob to release the clamp that holds the radio in place.  FIGS. 13A-13C  show various views of a radio mount  134  with two knob clamp locks  132  in accordance with one embodiment of the present invention. One of the knob clamp locks  132  is transparent in this depiction to show the knob  134  that is secured by the present invention. 
     The knob clamp lock includes two distinct components that fit together over the knob: a frame and a lock.  FIGS. 14A-14E  show various views and dimensions (in inches) of the frame, while  FIGS. 15A-15D  show various views and dimensions (in inches) of the lock. 
     As shown in  FIGS. 14A-14E , the frame piece includes a front face, a bottom  146 , and two sides  148 . Two separate slot openings  144  are located on the rear face  142 . The edge of the bottom  146  includes a back edge  149  that is bent in a “J shape” back towards the front face. Finally, one of the sides  148  includes a shackle opening  147 . In this embodiment, the frame is 1.430 inches high, 1.850 inches long and 0.969 inches wide. 
     As shown in  FIGS. 15A-15D , the lock piece includes a side surface  150 , a bottom  156  with a shackle opening  158 , and a back edge  154  that is bent in a “J shape” back towards the front.
