  1. Following on from Tony Hughes question below – firstly here is the spec for the MT500 that Tony refers to.

    As for how to connect it up to the MK8 I have written a new post above to document all the tips about the wiring that I have come across, including the advice on connecting the MT500 and a Phillips MK8.

    MT500The MT-500 is the latest Class-D DSC equipped marine VHF from M-TECH. It meets the EN-301 025 capabilities with integral CH70 watch receiver.

    Position Send/Request functions are also included which enable you to transmit/request the position data to other vessels. The received position data is transferred to a connected plotter (not supplied), if your plotter is DSC capable.

    Large SELECT/ENT knob can be rotated and pushed which offers you simple and easy operation for channel and menu selection.

  2. Dear Russ,

    Can you help me with an instruction to connect an Clipper GPS repeater to a Phillips MK8 GPS?

    I try to connect them, without a good result.
    I onely get info that there is a 12V connection, but no data info.


  3. We acquired a GPS Navigator MK8 with our boat & the instructions dated July 1993 & it worked last year, but now it just shows the position as zeros or similar if you change the datum base. Have tried replacing the Back-up battery ‘expected life 2 years’. All the tests appear OK, including the antenna. Any suggestions?

  4. Dear sir, can you help.
    I am trying to connect my Garmin 450 GPS to a M Tech 500 DSC VHF Transceiver.Both unit`s wiring instructions are not clear and although I have followed them correctly, The GPS is not speaking to the M Tech vhf, with no Lat or Long readingsor time etc.
    Be grateful for advice. Are they compatible?

  5. Hi,
    I have a Mk8 and just like Chris Woodd-Walker is has also stopped displaying Lat & Long. Is there a solution to this?
