+Hello and welcome hacker public radio audience. My name is MrX and welcome to this podcast.
+I'd like to start by thanking the people at HBR for making this service available to us all.
+HBR is a community-led podcast created for the community and by the community.
+That means you can contribute to just pick up a microphone, hit the record button and give it a go.
+You can use your mobile phone, an MP3 player, a dedicated audio recording device, a computer if you've got one.
+A tablet, phone, do I mention phone? No, no.
+Anyway, should I have something interesting to say?
+So this episode is part three on my, on explaining the controls on my amateur HF TS914TS
+radio and as I said previously I was, I said to split the recording up because it was getting too
+long completed and there's actually, I think at the beginning I say that there's three sections to
+radio but there's really four. First section is to do with the transmitter, the next sections to do
+with tuning in modes and such like the third section is actually to do with modes and memories and
+controlling the displays and whatnot. I kind of can't miss that out when I was talking
+with it in the very first part and the final sections that receive section. So we're doing the
+third section today. This is the dealing with memories and the vehicles and displays and such
+like. So a bit of a hot spot covers the main sub displays, meters, memory and ban keys of the
+TS940S. There's rolls of the tongue doesn't it? So sit back and enjoy.
+I'll briefly cover the display. Well the main display here because it's a sub display.
+So the main display, as I said before, I'm sure it's not LED, it's some other kind of, I
+wish I could explain this. But anyway, it's currently telling me I'm on VFOB. There's a V3
+next to the, a bit along from the VFOB symbol, a VFOB legend I should say. I don't know what the
+3 means. Maybe that's memory 3 or something like that. And the display is displaying 7.176.97KHZ
+killerhertz. And then there's two zeroes and killerhertz next to that. I don't know what that's for.
+Never used that either. Of course, I may as much as the studio I haven't used.
+Yeah, so I'm on 7.7MHz, 176KHZ, and 97HZ. That's about right, 970HZ I should say.
+Below the frequency to do, there's a scale that ties to emulate an old-fashioned,
+as I've explained to you earlier, a little fashioned radio that used to have a needle that spun
+up and down as you turn the tuning knob on the radio. There's that kind of, um, we
+radicals that go from zero to a thousand. And, uh, it's sitting somewhere between 700 and 800
+to 750-ish. So what does that mean? Let's just see 7. Oh, I, so I'm, it's giving an indication how many,
+tens of killerhertz, 700 hertz. Oh, I 700 hertz, that's what it's telling me, yes. So if I go to
+down here, so 7.1, 7.1MHz, 100 hertz. It's basically an idea to give you an idea how far up the
+band you are, um, so near the, so if we're starting at 7.1MHz, then at a glance, if I spin it
+at 500, that's half up the band. So I'm 7.151, what's it saying? So at a glance, without having to
+really look at the, the flickering, uh, display, as you're turning the big main dial,
+you can see how far up the band you are very easily. So you get the best of both worlds,
+you know, with, with an analog radio, with an analog, um, uh, display, it's very good, very easy to see
+where you are on the band, uh, but it's not very accurate, because the digital display with, with,
+with flickering numbers, it's very difficult to monitor what's where you actually are if you're moving
+up the band or down the band, um, it's a bit like the old analog and digital, um, meters. If you've
+got an old, an old Avo, you're measuring a, um, a fluctuating voltage, it's, it's very good to see,
+because you can see the meter swaying up and down and see what it's actually doing,
+whereas if it's, if it's a digital meter, just flickering up and down, you can't tell what the heck's
+happening, um, so it's a bit like that really, it's, it's kind of handy. I'll, uh, just put that back
+to them again. So, um, next to the main display, um, there's, um, there's a meter.
+And the meter, um, has one, two, three, four, five scales on it. The first, uh, scale is to do
+with signal strength and it starts at one and goes up to plus 60 dB, such as a, you can, an
+indication of how strong a signal is, is that you're receiving. The next scale is the power
+scale and that goes from zero to 150. I think they do, you can actually do a little bit more than
+a hundred watts, but as I say, I never go past about 70. Um, the next scale is SWR, standing wave
+ratio. So when the meter is in the SWR position, um, and you transmit it, it, it gives an indication
+what your SWR is at and it goes from one to infinity. Um, next one there's from that is IC,
+so input current and it goes from zero to 16 amps. Where that sits, I have no idea.
+Um, next one down from that is comp and that goes from zero, uh, 0, 10, 20, and that's not actually,
+it doesn't actually say what the, what's at the end of the scale, there's no number there,
+whether that's theatre or what I don't know, but it's decibels anyway. So it's a minute of compression
+that you're adding in and I, you would get that if you put it in the comp position.
+And, uh, ALC, so if you put the meter into the ALC position and start talking, you make sure you don't
+go, um, is that into the, into the, it's funny because it seems to be auto-limiter control.
+You've got a red section and a white section and the white section says 26, 28, 30 volt, no,
+it's white section says 20 dB in the, uh, red section says 10 dB.
+Yeah, it's perhaps, I should really know that, I shouldn't tie.
+By the way, my best gauge about the ALC, um, we've also looked at that.
+So that's, that's the main meter section covered, um, I'm all over the place here. I
+noticed it below the main display, there's, there's one, two, three, four, five, um, lights,
+one's on air, so that's a very old fashioned, on air, transmitting, you know, these days,
+you probably say TX, uh, but for transmit, but on air, there's an on air light, there's 80 antenna
+tuning, there's a tune light, a split light, and a notch light, um, but we'll, uh, we'll cover
+split, that's working split frequency between transmitting receive, um, and, um,
+notch will cover later, a tune will cover later, a, a, a, T will cover that later, antenna
+tune will cover that later. So if I go further along to the right, to the next section of the
+radio, um, there's buttons to do with, uh, controlling the sub display, um, it's a kind of green
+LCD, um, type of fear, and at the moment it's displaying the clock, I bet it's wrong.
+Um, but anyway, it says 1145, uh, is it 1145? Not quite sure, I'll have a look and see,
+it's not far out, it's 1130, I'm definitely going to have to split this, um, into multiple sections,
+um, so, um, so the, this, one, two, three, four buttons, um, for adjusting the sub display here,
+um, there's, I think there's, um, these, um, buttons actually have two functions to them,
+one of the few buttons that have two functions. So it's either clock, the first button is either
+clock or mode, um, the main functions clock, the sub function is mode, next one's a button's
+graph or hour, and the next one's scroll or minute, and the last one which only has one function,
+it is set, and it's basically for adjusting the clock, that's what that's, these are basically for,
+um, the graph one is, um, I think that's used for, um, to do this, a CW filter, which I'll cover later on,
+um, so that's those four buttons, the next one down from that, um, is it, well there's, there's
+one, two, three, four, um, five, six, seven, eight, the group of, can it eight buttons,
+I mean, they say memory function, and that, these, these are basically, to deal with memories,
+memory set, programs set, hold, memory clear, VFO, I mean, such between VFO and memories,
+memories, take, take to memory and put it into the VFO, um, memory in, enter. So it allows you to jump
+between, um, allows you to set up memories on the radio and allows you to jump between the,
+the, the variable frequency wherever you, wherever you happen to be, and jump straight to a memory,
+or put the memory into a VFO so you can move off that frequency if that makes sense.
+Um, I don't tend to use these keys very much, uh, below that band keys, and these are with two
+functions, these band keys, they can either, that there's one, two, three, four, five, six, seven, eight,
+nine, ten, ten band keys, and you can either use them for a, the second function of those is,
+to be used for memory channels, so you can, each button's got a number above it, so one to ten,
+one to, one to nine and a zero, so you could jump to any one of these ten memories basically,
+just by pushing the button, um, if you're in memory mode, um, but if you're in VFO mode, um,
+the main function of these keys, certainly on each key, as, as a, as a number, so the first one's
+1.5, next one's 3.5, then 7 and 10 and 14, 18, 20, 20, 24.5, 28 and 29, these are amateur radio bands,
+and so you can jump very quickly to one of these bands, by pushing single push to that button,
+so I'll go 3.5, the radio is just jumped, it's now actually doing 3.620, I'm guessing that's
+where I must have been, last time I was on the 80 meter band, the 3.5 megahertz is the 80 meter band,
+um, it remembers where you were last on that band, um, when you push these buttons, you hear
+really is clunking and clicking inside because of the, this is because of the age of the radio,
+so if we go back to 7, got to click, there you go, click in a beep, so that's me on back on the 40 meter
+or 7 megahertz band, quite handy, although because I tend to just sit in 40 meters, it's, um,
+it's, I don't use some great deal, um, there's also another way to, to, to quickly jump
+up and down frequencies, rather than jumping to a band, um, you can step up it, there's an up and
+down button, and that jumps the radio up by a megahertz, um, so eight megahertz, nine megahertz,
+ten megahertz, nine, eight, seven, now I'll actually back a seven again, I think actually the,
+the, um, main control, the main tuning control that I've previously covered, um,
+is speed sensitive, so if you turn it slowly, uh, it moves it in a very slow, you know, very,
+um, small increments, um, because it is a digital, although it's, it feels all unlogy and smooth,
+it is actually digital, and so that, if you move it slowly, the, the, the steps are very,
+very smooth and small, but if you fly it around that, you know, quick, then the steps increase,
+so you're jumping a bigger jump, so I think so, you can, you can, you can move about the band quickly,
+doing it that way as well, of course, um, so next to the up and down keys, there's an
+AT.T key, and that stands for antenna tuner, and if your antenna isn't tuned properly, and it's
+a lot, and not, then you can enable this AT-T key, and there's a couple of motors and capacitors
+and stuff in here, and it makes a right-old grinding noise, is it, um, is it tries to tune
+your antenna and bring the SWR down, it's, it's quite, it's quite, um, it's quite interesting to
+hear, um, I'm not going to do that just now because, um, um, on me is, I do, on occasions,
+causing to fears to the television downstairs, so I won't, I won't actually do that at this
+point in time, but Tim, it's a very handy feature, and I think it may have came as an option,
+option extra, and obviously the person who bought it, um, did that, and I actually used that,
+when I won 40 meters, uh, the antenna tuners, uh, active in all the time. If I move too far,
+say to the top end of the 40 meter band or the bottom end, and I've got to reach in the antenna,
+um, it doesn't cover the whole, the whole, um, the whole band, um, so, um, that's that, antenna tuner.
+Okay, so I hope you enjoyed this podcast, uh, I'll leave it at that, I think I've got anything else
+to say, I hope I've bored you too much, um, if you want to contact me, I could be contacted at
