RAM Mike installation at the pedestal.

What about interference with the autopilot?

I'm in the middle of installing my EV-200 and the instruction say to have any wiring for the EV-200 at least 3 feet from any wiring for a VHF.

My autopilot is an older Raymarine one where the display is also the control head. (The EV-200 has a separate computer right?) so we not comparing the exact same thing, but ...

I would think the signals travelling on the RAM mic wire are generally low level enough to not interfere. A different story if your actual VHF radio, or VHF antenna wire were close to the AP.

For me, I have the RAM mic wire, and ALL AP wiring (power, compass, drive, rudder, GPS) and all sorts of other wiring all bundled together through the pedestal, and beyond.

So far I've had no interference problems. I do get interference on my wind instrument when I transmit on VHF. My wind direction will spin randomly when I transmit. I suspect this is happening at the mast head, but I'm not sure. So, using my AP in Wind mode, and transmitting on VHF could cause some course direction problems!

Yeah, this is how our old one is setup.

I now have both a NMEA backbone, a power cord and the ram mic cord coming up the port side. I might have to change the ram mic if it gives me interference.

Probably not terribly useful, but I wanted to follow up on my post from earlier. Just a reminder - I had an old VHF (original from 2001) and RAM, but I purchased a new, AIS-receive VHF and RAM with which the existing cable was not compatible. When it looked like the smaller end of the cable wouldn't fit in the binnacle pipe, I hired out the job. It is now complete. I went onto my boat yesterday to check it out, and everything works great. I did have him also install the USB charger into the NavPod, so he had to move the new RAM plug to the left of center (which is where the old, incompatible RAM plug was) to make room for the USB charger. The overall job took him 9 hours (4 hours over his initial estimate), but I was only charged for the original estimate. I forgot to take a picture with the MIC plugged in, but here is a quick collage.

I went with the B&G V50 base with AIS and NMEA2000 in the cabin, and the H50 wireless remote at the helm.

I mounted the charger at the nav station so I dont have to leave the handheld out in the open when not in use. Battery life is plenty for a day.

I tied my radio with my Garmin chart plotter using N2K so the radio can get coordinates from the chart plotter and the Garmin can get AIS info from the radio....works pretty well for me.

I was out yesterday with my Simrad HS35 wireless remote mike for 6 hours - battery indicator showed 50% when I got back to the slip. The unit has a USB charging port, so I assume that with a long enough USB cable, I could plug it in to the 12v charging point near the helm.

You could always mount the charging cradle at the helm (or a second one at the helm), but I did not need that for my application.

The cradle would be nice at the helm as it holds the handheld nice and tight.

Curt, Which VHF did you install?
With me doing that job, would have taken me three days! I agree some things you should always do yourself but others need to be done by a professional!

Ran into the same consideration last year when I was upgrading my VHF and Chart Plotter . Went with the SH GX2200 with GPS / AIS and a RAM mike on our pedestal. Wanted to make it easy on the RAM but eventually broke down and cut the extension cable (OK per instructions) and fished the smaller cable up and soldered each wire of the cable back and heat shrank each one to seal. GX2200 with AIS is really nice and clear and am interfacing the AIS to my Raymarine Axiom 9 as an overlay.
Jeff - I am doing the same thing (I cut the remote mic extension cable to run it through my boat and am now splicing it back together. I’m having a devil of a time trying to make it work.
Inside the cable is a micro coaxial cable with a braided housing. Did you use some micro coax connector or did you solder the braided portions like another wire?

Any suggestions welcome.

Oops.
I installed the Standard Horizon Ram Mike. It came with a terminator fitting to install in the boat at the helm. The wire from the radio to the terminal fitting had a connection to the radio and bare wires on the end. I ran the bare wire end through the boat to the terminal fitting. Then it was simple to follow the diagram in the install manual pink to pink terminal etc. The mike then attached to the fitting by plugging it in.

Unclear where you are in the procedure.:facepalm:

Hi there

I am having the same issue, I had to cut the connector between the flash mount and the CT-100, and now there is no way I can get it to work
I have connected each cable by color, but only manage to power on/off from the RAM3+, do you have a diagram of the wires?
I understand that there are 2 wires (red & shield) wrapped in foil, but when I connect each wire, it does not work :frown::frown::frown::frown::frown::frown:


Cheers
