Modernized hardware complex MHC-5
The product MHC-5 is a modernized hardware complex with output power of the transmitter entering into its composition 5 kW. MHC-5 is intended to equip the associated and spaced radio centers of automated adaptive decameter-wave radio communication.
The product provides the possibility of combined, as well as spaced placement of receiving (KPO) and transmitting (KRO-5) sets of equipment, which are included in MHC-5, with organizing their TF and TG communication and control through analog tone frequency channel (TF) and/or through digital Ethernet interface. The complex provides the operating in traditional phone-only and telegraph modes, as well as automated adaptive duplex-mode radio communication using high-speed wireless decameter-wave modems, operating non-automated radio stations and organizing intercommunication.
The operating frequency range is from 1,5 to 30 MHz with the spacing of transmission and reception frequency setting 10 Hz. The minimum acceptable duplex frequency spacing relative to transmission operating frequency is 10%.
The main features:
The complex provides duplex-mode transmission and reception of the following data types:
- synchronous data transmission and receiving at TF channel (J3E USB or J3E LSB) during operating terminal equipment of type M461 or synchronous-interface-analog S1-FL with speed 4800 and 2400 bit/s in adaptive and non-adaptive modes;
- synchronous data transmission and receiving at TF channel (J3E USB or J3E LSB) during operating terminal equipment of type M-480F at synchronous interface S1-FL with speed 9600, 4800 and 2400 bit/s in non-adaptive mode;
- data transmission and receiving at TF channel (J3E USB or J3E LSB) during operating terminal equipment of type M-480F at interface S1-TF in non-adaptive mode;
- packet data transmission and receiving at TF channel (J3E USB or J3E LSB) during operating terminal equipment of type M448 or analog-interface S2 (RS-232) or Ethernet in adaptive and non-adaptive modes;
- packet data files transmission and receiving using high-speed wireless modem at speed 9600 bit/s at channel (J3E USB or J3E LSB) in adaptive and non-adaptive modes;
- telegraphy transmission and receiving at TF channel (J3E USB or J3E LSB) during operating terminal equipment T-206, T-208 or analog-interface S1-TG with speed 50, 100 and 200 bit/s in adaptive and non-adaptive modes;
- service audial telephony transmission and receiving at TF channel (J3E USB or J3E LSB) in non-adaptive mode;
- telegraphy transmission and receiving in mode FT-500 (F1B) and FT-250 (F1B) during operating terminal data equipment (TDE) at interface S1-TG with speed 50, 100 and 200 bit/s in non-adaptive mode;
- two channel telegraphy transmission and receiving in mode DFT-500 (F1B) and DFT-250 (F1B) during operating terminal data equipment (TDE) at two independent interfaces S1-TG with speed 50, 100 and 200 bit/s in non-adaptive mode;
- telegraphy transmission and receiving while working with the key in mode AT (A1A) in non-adaptive mode;
- telephony transmission and receiving at one TF channel (J3E USB and J3E LSB) during operating terminal data equipment (TDE) at interface S1-TF in non-adaptive mode;
- telephony transmission and receiving at two TF channels (B8E) during operating terminal data equipment (TDE) at two independent interfaces S1-TF in non-adaptive mode.
