Rohde & Schwarz 사가 제조한 m3tr 이란 무선기를 소개 합니다.
당장, 등에 메고 삼악산 에라도 올라보고 싶네요.
mr3000h 1.5 ~ 108 MHz(수신 500 MHz 까지)
mr3000u 25 ~  500 MHz  이렇게 두종류가 있네요. 이중 아무래도..아마추어무선과 관련이 더 많은 mr 3000h 쪽으로 눈길이 더 많이 갑니다. 이후 이내용을 옮겨 봅니다. 과연 가격은 얼마나 할래는지...

Advanced HF/VHF Tactical Radio R&S MR3000H

The R&S MR3000H belongs to a new family of high-performance digital radios covering the HF and VHF/FM band in a single unit.

Thanks to different high-speed data modes and protocols as well as different antijam modes for HF and VHF/FM, it perfectly integrates into tactical communication networks.

The radio is software-configurable and reprogrammable including pre planned product improvement (P³I).

All members of the R&S M3TR family are based on one mechanical platform, with a common logistic concept and one man machine interface (MMI).


◆ Multiband capability (1.5 MHz to 512 MHz with external devices)
◆ Multiwaveform capability
◆ High data rate up to 64 kbit/s for data and video
◆ Software-configurable and upgradeable (P³I)
◆ Selective links in one net
◆ Low volume/weight
◆ Power saving mode
◆ Integrated GPS and position report
◆ Removable front panel for flexible use and integration
◆ User-friendly MMI

External amplifiers
50 W VHF power amplifier, 50 W VHF/UHF power amplifier, 150 W HF power amplifier
The Power Amplifier R&S VK3150 increases the HF output power of the R&S MR3000 manpack radios to 150 W PEP or 100 W average. The R&S VK3150 provides medium-power/medium-range communications links. Typical applications include mobile or base station installations for general-purpose HF SSB voice and data communications.
Continuous coverage is provided over the 1.5 MHz to 30 MHz frequency range. The power amplifier section is of broadband design and fully supports frequency-agile operation modes (automatic link establishment, slow frequency hopping).
When used with the automatic HF Antenna Tuning Unit R&S FK3150, the output of the R&S VK3150 is automatically matched to most rod and whip antennas and requires no special operator procedures.
Built-in self-test features permit operators or maintenance personnel to fully check the transceiver and associated power amplifier performance down to the module level. Fault conditions are displayed on the transceiver's front-panel display.
The RF drive requirements for full 150 W PEP or 100 W average are –2 dBm (±3 dB) from the associated receiver- transmitter.
The manpack R&S MR3000 therefore acts as an exciter for the power amplifier, avoiding the disadvantages of transceiver/ booster solutions with respect to unwanted emissions.
The HF power amplifier is mounted separately on an independent shockmount with room for proper air flow. This provides additional flexibility when installing tactical radio systems into vehicles.
The R&S VK3150 uses rugged tactical packaging and meets the same environmental specifications for temperature, shock, vibration, and submersibility as the rest of the R&S M3TR family components.
