TYT MD-2017 Dual Band DMR Handheld – coming May 2017

As spotted by Steve VK2ZSW (thanks Steve!).

Remember all those dual band Chinese DMR radios that are coming to revolutionise the affordability of digital voice modes?  Here’s another one to add to the list, and it’s from the maker of the nearly ubiquitous MD-380 – TYT.  Interesting naming convention they’ve got going on here.

Article below from HamRadioReviews.eu, original post here – published Feb 15, 2017.

TYT just released the first ever image of the upcoming TYT MD-2017 dual band DMR handheld radio.

Back in November, a photo of a poster from PMR expo 2016 was published online, showing the MD-2017 model.  At the time it was still a rumor, as no other official information was released from TYT.  Just 10 minutes ago, the image you see above was published.  Still not at good resolution, but it provides some information.

First and foremost, it is no longer a rumour.  Second, the first 3 bullet points in the characteristics of this “leaflet”, indicate that it does support true TDMA.

It is rated as IP67 waterproof (which is always a plus) and has a GPS module.  Most likely, this will follow other models from TYT like the MD-380 or MD-390, which came in non-GPS and GPS versions.

Other than that, the model looks kind of chunky in size.  It has what looks like a proprietary antenna for waterproofing and a guard for the turning knob at the side.  There does not seem to be a channel-selection knob, which is kind of weird.  There are 4 buttons on the left side, with the PTT being in orange.  On the right side is the cover of the accessory port, which is screwed on for weatherproof-ness.

The keypad has two programmable keys (P1 and P2) which are shared with Menu and Back respectively.  Between them, there is a joystick-type rocker key with an extra button at the centre. Below these, the number keys with “0” at the left side.

The screen is colour and shows frequencies in large numbers.  This is also an indication that the radio is most likely designed with ham radio usage in mind, instead of the commercially targeted designs of previous radios from the company.

Here are the specs mentioned [my comments in square brackets]:

  • Dual time slot for point to point [they probably mean simplex]
  • Dual time slot for repeater
  • Use Time-Division Multiple-Access (TDMA) technology
  • Compatible with Mototrbo Tier I and II [we’ve seen that before]
  • Lone worker
  • Encryption function
  • Analog and digital combined [I hope this means something more, eg. watching analog and digital at the same time]
  • Single call, group call and all call
  • Remote kill/stun and activate
  • Firmware upgradeable

Expected release date is May 2017. No info on pricing yet.

Excellent video from the ISS

Recent use of HAM-TV on the International Space Station in Europe has taken this popular educational activity to a new level.  The Collège André Malraux in France asked ARISS Europe for HAM-TV support for its scheduled contact with European Space Agency Astronaut, Thomas Pesquet KG5FYG.

The experimental HAM-TV was possible due to the equipped ground stations in Europe to provide video coverage from the ISS downlink signal.  This particular contact had voice transmissions from the ISS on the UHF band on 437 MHz, with a ground station at the school.  As a back-up feed to the school was the ON4ISS ARISS telebridge station in Belgium.

ARISS (Amateur Radio on the International Space Station) lets students talk directly with those on board, inspiring them to pursue interests in careers in science, technology, engineering and math, and engaging them with radio science technology through Amateur Radio.

The contact lasted about 10 minutes on Monday 13 February and also involved a series of five radio amateur radio ground stations in Europe equipped with the HAMTV receive capability.  These were linked together forming a chain for the video from the ISS.  It had a downlink signal of 2395 MHz and was streamed live on the British Amateur TV Club server seamlessly, using Multi viewer technology which selects the strongest signal.

The video from space in real time was excellent, with Thomas at first testing, and seen checking that the antenna was correctly connected to a hand-held UHF transceiver and the correct frequency was set.  Then, wearing a head-set, the astronaut answered 19 questions in the French language prepared by students watched in awe at the school by an audience of 190 students and guests.  Looking at the camera and gesturing to areas in the Columbus module he seemed at ease in dealing with the inquiring youngsters.  The contact ended with a wave from Thomas, a thank you, and then he floated out of sight.

HAM-TV from the ISS has certainly added a new dimension to talking to the crew on the International Space Station.  It is just another part of our part of our diverse hobby an exciting opportunity to inspire the minds of students and to hopefully generate a greater awareness of our unique hobby.  With two stations already in Australia being HAM-TV equipped ground stations, Shane VK4KHZ and Martin VK6MJ, hopefully video from the ISS via HAM-TV is a possibility for an Australian school.
