ericloe,
FYI:
I have the
Simrad RS40-B and HS40 wireless handheld. To my understanding, these radios are exactly the same except for the branding. I have what sounds like the same setup, and issue as you.
VHF installed below
deck on sailboat, wireless handheld at
helm, and
remote speaker at
helm.
I too am having the audio repeat issue. My radio is also missing the menu option to turn off audio repeat. When I contacted Simrad, I was instructed to update the
software, which I have not yet attempted (I have a
Raymarine MDF, not Simrad/B&G). My
current software version is V4.18, and the most
current update available is V3.74. I asked about this when speaking to the Simrad tech, and I was told that V3.74 was the most up to date version, and that I should install this version. I was given a case number, and told to call back if this did not fix my issues.
I intend to attempt to to try and install the software update using my
Raymarine MDF, and will report back if I have any success.
