This is a SwinTek Full Duplex Radio Interface System MK200DV & MK200DT with Drop in charger, multiple battery packs, power adapter, Shure VR230 headset mic, radio interface cable for the fixed station end. SwinTek makes ruggedized radio system for the military, for explosive environments, for crane systems, etc. This is a full duplex FM radio system that operates on 75.44 mhz and 171.045 mhz. The portable unit has a Shure VR230 headset/mic combo. The ear pieces could use a replacement foam cover, the originals literally dry rotted in storage but the headset works fine. The portable unit has mic gain, volume, and squelch adjustments. The fixed station end also operates on 75.44 mhz and 171.045 mhz. It has a radio interface cable to connect it to your computer or other radio. It has a receiver squelch adjustment. I have verified the operation of both the portable and fixed station radio units. The drop-in charger has 4 battery packs, but I suspect they need cells replaced due to the long term of storage and non-use. The charger is in good shape and works. My original plans were to set it up as a full duplex interface to my HF rig so I could  operate HF from the workshop or around the property by simply connected the fixed station end to my HF rig's audio in/out connections, and setting the HF rig to VOX. I installed an additional radio station in my workshop and never followed through with those plans. Other uses are interconnection to your computer sound card for operating equipment via voice recognition. This was a very well made and expensive full duplex radio system, but I no longer have a use for it in my ham radio operations. I have no schematics for this equipment, although operation and interfacing is very straightforward and self explanitory. I have emailed SwinTek about obtaining paperwork, if available. Shipping is free in the USA.
