  1. Head’s up: If you get a new VHF, you may be surprised to see that some channel numbers are shown as four digits starting with “10” like 1007 instead of 07, 1018 instead of 18, etc. The USCG explains here:

  2. I’m glad to finally see SH go wireless with a decent handset. For the last few years I have been using the B&G V50 with the wireless handset, and the handset is not that great from the quality of sound and speaker side of things. I recently replaced it with a good, trusty GX2200 and the wired RAM3 mic, but would have much preferred a wireless one. Unfortunately, all of the ones I’ve tested in the last 6+ years have had their issues.

    Seeing SH use WiFi for the remote gives me hope that the clarity and quality will be good enough. Looking forward to a longer term review around the wireless remote!

    I know I’m likely in the minority here but I’m not a big fan of wireless instruments and radios on boats. The functions of these devices are critical, I don’t feel much need to be able to roam while using them, and wires are much more reliable. I do like SH’s trend towards allowing multiple RAM mics off the same head unit and I’m glad they’re finally embracing N2K. Now if they can just get that integrated AIS transceiver issue worked out they’ll have the perfect package.

      I agree with you regarding wireless equipment.

      The problem is that many manufacturers insist on supplying cables with permanently mounted connectors that are impossible to pull through some of the spaces on boats. I have a wired remote microphone on the fly bridge of my boat and ended up having to cut and splice the cable in order to route it. The manufacturer specifically told me not to do this; yet the connectors on the cable wee not field replaceable.

  4. The main reason that SH is unable to ship their GX6500 VHF/AIS tranceiver is that the internal class B transponder is a Amec CSTDMA type transponder. The patent on this technology is held by their fierce competitor SRT since July 2015. Until SH (Amec) and SRT sort out this issue there will be no product in the shops worldwide. Apart from this legal / commercial issue, preliminary tests appear to show that the GX6500 only just barely complies with some relevant standards. Authorities are not very happy with these results and seem reluctant to clear the GX6500.

  5. Hi Ben,
    The information cited was published on the Dutch Sailors’ forum by a (long known and trustworthy) professional in the VHF / AIS field. He said (Nov ’17) that a Dutch SH representative told him about the patent issue. I cannot verify this in person, but I have no reason to doubt his words given his reputation in the Netherlands.

    The same goes for the troublesome compliance of the AIS transponder. He claims to have thoroughly tested the Amec transponder involved (his company installs and tests VHF and AIS equipment for both industry and government for a living) and reported the ‘meager’ outcome: just barely compliant. He mentioned that ‘jitter’ was particularly an issue and that this seems to be one of the main reasons that SH can’t get the EU approval stamp on the GX6500.

    Let me be clear, I’m not an expert myself, just repeating what information is available. I’m an enthusiastic user of SH equipment and I know many boaters would be interested in a combined VHF/AIS transponder. It would be far better if SH themselves would clear up the mist around the GX6500. But for some reason the mist is very, very persistent.

    Re the cause of the Standard-Horizon GX6500 lacking approval by the USCG and FCC being due to infringement of a patent (as proposed above by Timo):

    I join Ben in being skeptical that approval of the GX6500 is being withheld due to a patent infringement. The two regulatory agencies involved in granting approval in the USA are the FCC and the USCG. I don’t believe either of those regulatory agencies are concerned with protection of intellectual property. If there were a patent infringement, the owner of the patent would have to seek redress in some other venue than with the FCC or USCG. I am not a lawyer, but I believe that in the USA the federal court has exclusive jurisdiction over patent disputes.

    Jim, I may have been unclear in my previous posts, but as I have understood there are two separate issues at hand: one is a possible patent infringement, the other an approval issue. These issues are unrelated I guess. As Ben pointed out, the patent issue may be solved or non-existent anymore, but apparently the technical issue(s) seem to remain. This lies with the FCC / USCG in the USA and with a notified body in the EU.
