     FIELD OF THE INVENTION 
     The present invention relates generally to an integrated power supply and docking platform. In particular, the present invention relates to an integrated power supply and docking platform for a Satellite Communications (SATCOM) radio frequency power amplifier for forming a single physical platform with integrated power electronics. 
     BACKGROUND ART 
     The U.S. Department of Defense employs a type of UHF, VHF-FM, and SATCOM combat net radio known as the “Harris 117 Radio”. These radios have a military nomenclature of AN/PRC-117. The HARRIS 117 radios, are designed to provide the primary means of tactical communications and control for U.S. ground mounted and dismounted units, all in coordination with naval and air support. HARRIS 117 radios are designed on a modular basis for achieving maximum commonality among the various ground airborne system configurations of the armed forces. HARRIS 117 radios provide U.S. military commanders with a highly reliable, secure, and easily maintainable tactical radio net. 
     HARRIS 117 radios possess a nominal input power requirements of 24-32 volts direct current, which is supplied by rechargeable on-board batteries. Recharging the HARRIS 117 radio batteries is inconvenient and, in certain mission applications, unattainable. Currently, specialized and complex battery recharging systems are available for recharging HARRIS 117 radio batteries; however, these systems are not always operable in a given application.

     DETAILED DESCRIPTION 
     An exemplary embodiment of the present invention is illustrated in  FIGS. 1-5 , where like portions share like numbering. As illustrated at  FIGS. 1 through 4 , an adapter assembly  10 , in accordance with the present embodiment, includes a base  12  having a front side  14 , a back side  16 , opposing lateral sides  18  and  20  and a top side  22 . Top side  22  is adapted to simultaneously support a HARRIS 117 radio  24 . To that end, top side  22  includes a substantially flat, horizontal first platform  28  for supporting HARRIS 117 radio. 
     Extending upward from top side  22  at a 90 degree angle and forming a portion of backside  16  is the support structures for further supporting HARRIS 117 radio  24 . More particularly, the support structures include a vertical support clamps  34  extending upward from the platform  28  and having a width corresponding to the width of the platform  28 . 
     A first connector  38  is positioned and arranged so that first connector  38  is in alignment and capable of interfacing with a complementary receptor socket on the rear of HARRIS 117 radio  24 , when radio  24  is installed on the platform  28 . A suitable connector for use as first electrical connector  38  is 6 pin radio connector type designed and manufactured by Perkins Technical Services, Inc. Receptor contacts  42  are positioned within first connector  38  to receive corresponding male connectors extending within the complementary receptor socket on the rear side of HARRIS 117 radio  24  in accordance with government specifications established for HARRIS 117 radios and HARRIS 117 SATCOM and radio frequency power amplifiers. 
     2 binding Posts are positioned on the backside to provide direct current take off power for the external power amplifier. in accordance with government specifications established for HARRIS 117 radios and HARRIS 117 SATCOM and radio frequency power amplifiers. A third binding post is positioned as a ground drain for external power amplifiers requiring a ground. 
     A control switch  50  is provided on front side  14  of base  12  for controlling the initiation of power and/or charging for HARRIS 117 radio  24  when installed on adaptor assembly  10 . The front side  14  further includes a set of speaker access holes  52  and a microphone adapter  54 . The set of speaker access holes  52  allows sound generated by a phone speaker housed within base  12  to exit base  12 , while microphone adapters  54 ,  55  provide a means of connecting the input/output of a HARRIS 117 radio handset to speaker to allow microphone out signals to be transmitted to an audio amplifier circuit and ultimately to speaker. 
     Opposite front side  14 , a standard power plug  58  is supported within back side  16  and is adapted to plug into a standard 110/220 volt household outlet via an electrical cord. The backside also includes a subminature “D” 26 pin connector allowing access to the connector from the backside of the Harris 177 radio  24 . Additionally a subminature “D” 9 pin connector to allow the radio to be controlled by TOCNET and a Circular connector to provide the ability of the unit to accommodate a LS/671 SINCGARS External Speaker with Microphone/Handset. Backside  16  further includes a pair of fan access holes  60  to allow a flow of air through base  12  as generated by a pair of fans. 
     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 basestation will also broadcast the audio signals from the Handset plugged into the LS/671 External SINCGARS Speaker. 
     While the invention is shown in one form, it will be obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit thereof. For example, various plug placements on the rear member of the invention as well as to accommodate upgrades and modifications to the current HARRIS 117 radios used by the Armed Forces. Moreover, the height of the rear member and orientation of the electrical plug on the rear of the invention could easily be varied to accommodate different types of radio configurations. These include the HARRIS 150 class of radios as well as other variations and versions of the radios and communications equipment. In general, it is physical dimensions to meet various types of HARRIS 117 radio configurations exist, such as those in existing model numbers: Ground ICOM radios using receiver-transmitter. These models are fully intended to be used and are compatible with embodiments of the present invention.
