Instructions and Help about Are Form 8453 S Transmitter

This is Dave ke 0og and I'm your guide through the a double RL study guide for the technician class license and today we're going to pick up the book and talk about transmitters and receivers at section 5.1 now as it turns out down at the bottom of the page it shows a ten tech Jupiter I happen to have one of those so why don't we just use that and I'll walk you through the functions let's take a look hi this is my 10 tag Jupiter this is an HF transceiver it is mid-range and a very nice one I haven't liked it very much I've had it for a little over ten years it's recently been replaced on the market by the 10 tech eagle but it is still readily available let's look at some of the functions this is the power switch right here turns the whole thing on and off okay it's fundamentally computer inside so it has to boot for a minute here's the volume control okay so we're listening on 80 meters now the next most important knob is the tuning see as we tune it the numbers just go up doesn't look like a radio dial anymore and you can pick particular steps that you want by pushing on this step down here and picking whether you want to go up or down in you know how fast the thing moves the next most important item is the band switch here where we switch between the bands it's 160 meters and then it comes back around to 10 12 15 17 20 and the 10 megahertz band which is 30 meters the 40 meter band the five frequencies that we have in the 60 meter band and the 85 meter band which sometimes the high end of that is referred to the 75 meters okay now there are different modes let's see if we can tune in that station again here okay now we've got the modes you see the mode indicator right here it says lower sideband we can toggle through the modes CW FM AM upper sideband and lower sideband which of course is the one that works here now if we want to tune the thing in exactly let's change our step back to when it hurts come right down on it there's a little receiver incremental tuning knob over here which when you turn that on just get that signal tuned in just right now reasons you would want to do this is if you're transmitting on one frequency and your partner starts drift you don't want to chase them down the band the thing also has on the screen here it can has a split VF all right now we're both transmitting and receiving on this one but sometimes when you work DX stations you want to work split so you can have two frequencies in here transmitted on one receive on the other the subtle indicator right here is called the s meter it tells you how strong the signal is in relative terms an S 9 signal is considered very good and as you can see they are coming through much more strongly than that if the signals are too strong there is an attenuator that cuts down on the incoming signal a little bit the box is you can just talk into the microphone without pressing a push-to-talk and the tuned button just turns the transmitter on a little bit so you can tune your antenna with the antenna too it's up top there's also an auto knotch right here that if you hear a single tone it will cut that out for you a noise reduction which is a digital noise filter now in your controls down here you have the audio also the RF gain normally you run that a hundred percent unless the other guy is really really strong but sometimes you'll want to cut that down now some of these other features in here are kind of unique to different radios not all radios have them passband tuning is a way of cutting out some of the interference here you have an AGC you toggle through fast medium and slow on the AGC can set the key speed for CW if you really want for FM you can put a squelch in here this is the side tone monitoring level and so on now these down here allow you to use memories you can put a frequency into memory if you want to get back to it very quickly the mic gain adjusts the gain of the audio circuits going out so you are not causing a problem with Distortion the power level you can set the power level in here anywhere from a hundred percent which is a hundred watts on this radio and if for some reason you want to work with very low power it says zero percent but there's actually a little bit going down so that's why we would keep a dummy load for that and if you so we talked about the most which the band switch the reverse these things have to do with the two memories here working split which I very rarely do as little indicator when the transmitter comes on another indicator if you're over modulating that little light comes on and tells you that it's too much and the radio automatically cuts back on it this particular radio has control over the bandwidth the received bandwidth so that you can get right in on the signal that you want this is an extremely nice feature passband tuning is controlled here in the multi knob it depends on which of these that you push and that's about it for a quick basic tour of the ten tech Jupiter radio now we're looking at a handheld radio this little radio right here happens to be an icon it's an
