Finally, you have that boat that you have dreamed about for so many years. But before you take it out for a great day on the water, you need to outfit it with electronic accessories that will make your boating experience safer and more fun. Northstar Marine Electronics knows exactly what you need to get the maximum enjoyment from your boat.
To begin with , a VHF radio is a safety feature no boat should be without . If you or your boat is in distress , a VHF radio can make the difference between finding help right away and being left to your own devices. The NS100 VHF radio is available in single station and dual station models. They include dedicated distress call button that transmits your MMSID and location until an acknowledgment signal is received. It accesses all sea VHF channel banks, even the weather ones. The Northstar Explorer 721 and 725 have a built-in barometric pressure sensor that gives weather and fish activity predictions. The "Happy Fish" icon on the monitor helps you in determining the likelihood of finding fish. Both the 721 and 725 models can each be equipped with wireless handheld units, in addition, the 725 has a "Track Your Buddy" feature for locating up to three boating companions and storing their locations on your chart display .
Northstar Marine Electronics has a range of navigation tools, including the Chartplotter 8000i, a multipurpose instrument with a 12 inch touchscreen display. If you a're going to acquire one piece of equipment other than a VHF radio, then you might want to consider the 8000i. It features the following goodies: chartplotter, depth sounder, radar, video monitor, network camera monitor, DVD player, CD player, music jukebox, fuel and engine management system, and instrument repeater.
If you're just looking for a chartplotter / sonar combo , then you should go for the Explorer series, models 660, 657, and 650. Each model has a built in 32 megabyte background maps with intricate cartographic detail. It gives you the option of using C-MAP NT MAX chart technology provided by cartography leader C-MAP.
The Explorer 538 is a stand alone chartplotter with a simple menu system and daylight viewable screen. It comes with the regular 16 megabyte background map and has a place for the C-MAP NT MAX cartridge. The 3.8 inch screen is "transflective" with high contrast so you can read it in daylight easily. This chartplotter is an excellent companion electronics component with the Explorer 438 fish finder. The 438 model has a 640 x 480 monitor that offers great detail. It has digital sounder technology to give you the highest quality sonar images. Advanced displays include A-scope, split screen variable zoom, and your choice of color palette. With 256 colors, you can see the nature of the floor structure and detail that will help you identify fish habitats.
Choosing marine electronics doesn't have to be an exercise in frustration. Northstar has the marine electronics equipment that will help you enjoy your craft safely and comfortably while using electronic equipment that's at the leading edge of technology.
what are some differences between VHF and UHF ham radio?
I am considering purchasing a Dual band ham radio. I have been looking up some research and find that other hams are saying UHF travels shorter physical distance, but through buildings better. does this mean it travels through buildings in an urban environment, or does it transmit and recieve better while you are actually in a building? and does VHF go much farther than UHF signals? any information to add is greatly appreciated to this new ham! thanks a lot!
Welcome to the hobby of Amateur Radio (HAM Radio).
The main difference between VHF and UHF are the frequencies they broadcast on. 2 Meter radios (VHF) operate between 144.0 and 148.0 Mhz. 70 Centimeter (UHF) radios operate at 420 Mhz to 450 Mhz.
Granted, Different frequencies do behave differently under varied circumstanses. VHF frequencies makes it through trees and rugged landscapes, but not as well as UHF does. However, if VHF and UHF signals wave were transmitted over an area line-of-sight, the VHF signal would travel almost twice as far. This makes VHF easier to broadcast over a long range. Some of this should have been covered in your testing. You may want to go back to your review book(s) and read up on radio propagation. Understanding it will improve your operating practices.
Most amateur radio operators and repeater operators operate on either (or both) UHF or VHF, so it's a great idea to get a dual band radio, especially if you're just starting out. The local clubs/organizations around here almost all have repeaters on both bands.
