Re: Long-Distance WiFi Device

Totally agree. I spent seven years in the Caribbean, also using a Bullet. I imagine phone providers have improved the situation a little but it's interesting to know by not much.

Re: Troubleshooting Vacuflush

Duckbill valves will probably fix the problem but use double hose clips back to back with 180 offset on connections each side of pump. Warm hose with hairdryer before tightening.

I think he was referring to the fact that his latest laptop wouldn't run on straight 12 volts unlike his previous.

Re: Running a laptop without an inverter

DC is DC yes but your laptop will require a specific voltage usually above the nominal 12 volts available on your boat.

Bottom line the average control panel won't take the necessary 30 amps or so required by a fully modulated 150 watt rig.

Re: Icom 802M GPS with Raymarine

From a safety point of view you should be feeding your DSC equipment directly from a GPS source. This would give you the required GGA sentence with $GP prefix.

NMEA v2.0 or 3.0 is not an issue...

Re: Long-Distance WiFi Device

I think the main differences in using a Bullet 2HP & M2HP (specs aside) are generic & not attributable to the devices as such. 802.11n devices can work in three modes:
greenfield - pure 802.11n, no...
