so we've already upgraded the ts590 once with the vgs vsg-1 unit which is the voice voice unit
today's the tcxo which is the frequency stability oscillator also these amazing
military looking side panels right two jobs today we've got the txco
uh stability oscillator thing to put in this ts 590
and i've also got these really cool side plates i'll put a link
to where you can get these from uh i just thought they're really cool so anyway the most difficult
job is probably putting this thing in we've got a soldier in this is the official kenwood part
i was gonna look for the chinese knockoff at 10 pounds or something but
i read some reports that it was uh doing some bad things all right so it is absolutely tiny
that is the size i thought it'd be a bit bigger small isn't it now i
was told by tony down at martin lynch that the charges are it doesn't need adjusting
99 of the time you put it in and it fixes all your frequency stability problems you might have this
is an amazing radio i just what this is the final upgrade excuse me this is the final upgrade for me
so we need to take the bottom cover off first i'll shut up and do this in speed time
right with the bottom cover off apparently because i don't remember
how it did this before oh here it is
uh i've got to take
this board here i'm going to take that board there which is next to the volume and the
wrist and stuff and there's one screw holding it in ah there's the screw just there all right
now you've got to take these jumpers off
both sides
i don't know how they come off
it says to save the jumper
oh hang on a minute is that okay i think that's soldered in so we can leave that one
i think i don't know doesn't say in a plumbing manual
and which way round does it go i don't know a lot of things
blimey it's small
and one of the pins slightly bent in the wrong place
probably doesn't matter does it which way around it goes
well i'm not very good with small things that's why i was terrified of buying this bloody thing
i can't see my eyesight's all over the shot okay does it matter which way round it goes
let's have a look at the instructions which are here helpfully
for instructions referred to instruction manual provided
well luckily i've got that over here so let's go and have a look
okay so
all right so the adjustment hole is to the right of where the little pip is adjustment hole is
to the right so i was the wrong way around if i'm going to follow their instructions
that's it so now it's just a case of clamping that together somehow i'm going to get lockies
soldering iron
and attempt to solder all this in
all right let's go and get the iron all right so lucky wasn't using this so
i think what we'll do is we'll switch it on
to what temperature this should be at i don't want this to move around
do i so i think what we should do is uh put a little bit of tape on the ground fold it over
and that should hold it still
ish then when we push down
it should be all
right i'm not an electronics engineer guys you know i'm just a geezer he tries his best
but this bit frightened me to be honest it just does
i mean it's one of these things if you do something often enough it's kind of easy but
when you don't do it very often it's not very easy so let's just get a bit of heat onto that no more
i think that's all i don't think i've destroyed it yet
i'm gonna get some ipad without glasses in a minute and double check this
you'd think that would supply a little pcb with it don't you
let me get some glasses
so i've got a little trick here that i wear
some strong pair of glasses and then my glasses over the top and see what i'm doing in more detail
i haven't got a camera that can show you this i'm sorry i might take a photo yeah
i'll take a photo with my iphone it looks absolutely fine so thank goodness for that
ah photo take a bit of video for you it's a bit difficult to see isn't it
it all looks okay all right
right got to put it back in now which way did it go
okay it's actually a couple of days later i've cheated i made a bit of a cock-up um yeah just
on a configuration of the jumpers and that sort of thing and i've also when i reviewed the footage
i realized that this could have done the two outside posts of the temperature compensating
crystal all this oscillator t temperature tc xo uh it just looks like i could have done
a better soldering job so i've done that i'll give you a close-up of that while i'm chatting
so it's just a case now getting these pliers and pulling off these um jumpers but we need to save
them for a rainy day just in case so the idea is you pull the jumper off and just move it by you
know one over and and that's that's done so let's film this as i said earlier i'm not very good with
very small things but anyway pull that off and put it on the next one then we'll pull that one off
and put that on the next one so that will save these little jumpers
for a rainy day and then we just plug the uh t6 spoke tc exo back in uh i've
said previously i've got enormous weight it feels like i've got enormous hands
some people are just better with little things i think i don't know i'm gonna attempt
to hold this while at the same time keeping the screw in the i'm all over the shot
what no okay i'll do it differently i'll place the little board in
the next thing i'm worried about is how to calibrate this because the manual says
listen to the tone at 10 megahertz i can't hear it because i could just can't receive that here
uh so i think we'll just sort of see what it without any calibration we'll see what it's like
all right so technically that is in the only thing we haven't done is actually calibrated the crystal
um i don't know what to do about that all right let's bang it back together and put it on the uh
i mean i suppose i could calibrate it against the
ts590 or just find a fairly accurate signal on on the 10 meter band something like that let's uh
let's put it on the bench upside down see if we can do that
okay because i don't know what i'm doing i've um i well i found this video which
plays 800 hertz that's all i did and i played it on how it hurts now i'm really comfortable
with the my ts 990 so what it did is i transmitted 800 hertz because i couldn't find a signal from
the headphones of the pc into the microphone and i could hear it on here so at least i've got the
um the 990 and the 590 in sync it took a bit of fiddling but we got there i'm not going to film
all that but um and it was a bit out actually was quite a bit out i mean you know a couple of notes
away to be honest we'll be able to prove that when we go out on the hills on the on the 13th
of august because we're taking this with us uh i might do a little test in the week actually
plug it in with the amplifier and everything and make sure it it's [ __ ] on but that is working so
we can bang it all back together again so sorry about the full start um but you know um what do
they say um needs must don't they i had to find a way of finding an 800 hertz or any signal frankly
that i could transmit on the 990 and at least sync up the 990 with the 590. that's all i want
to do to be honest all right well i recommend you do watch that um i mean if you actually wanted to
do this upgrade yourself i'll put a link to the video i i just watched actually which was you know
the professional guy you knew it was doing wasn't hobbyists like me when it comes to electronics
good let's bang it all back together by the way i've got i've got all my radios on
these over spec'd 50 amp cables because sometimes i want to run a lot of power
whatever anyway so that's when the thing's in the shack because i can
apply these terminals straight to a power supply and if not i can just plug that straight into
all the batteries so i've got everything on 50 amps because sometimes i might want to
run a linear on one and whatever so anyway that's what i'm doing on the 12 volt front
let's get this back on the bench and start to put these plates on because this looks a lot of fun
only one side can go one way i think
so this man it's a polish fella this looks nice let me get this little camera
so these plates they completely protect the front of the panel he does supply little screws just
for here now these little tails if you lay the um rig down on its back you're gonna protect
from here as well they're i think they're steel so it's not i mean it's not a portable portable radio
anyway right so it's great for holidays and stuff like that and frankly just makes it look really
mean let's install them now uh i don't have to use the washers or not put the washers underneath
that's strange we get given washers i don't know
if we should use washer washers or not seems a bit weird because these are machine screws
so what i've decided to do is put a little bit of tape on each side of here and use
the washers he supplies
because well he's supplying him for a reason isn't he ah before he stopped dropping them
that's my big chunky antenna fingers again so i'll just lay these on top with the burr
oh i don't know i mean the chances are
this will be like this forever anyway so i think i can just lay that on top
and then silly me what i have noticed is he actually supplies a tool i was looking for mine
just find the thread over here the right size it is number one
all right so this is the final upgrade it's had the voice unit it's now that the tcxo
to be honest i've got no idea how some of these things work but i just wanted to be
more accurate on the frequency particularly as i went up to 10 meters and six meters
and it will stop the drift as well on things like um
ft8 you know the first half an hour because this is a traditional the last of the big
all right we shut up put on the other side and we can have a little look at it
right let's have a look
nice
i'll show you well to be honest i'm dead chuffed with this so um we're going away
on the 13th of august it's a saturday night big bunch of us there's six six amateurs going
we'll use this radio probably with an amplifier and uh so you'll hear us might live stream that
so remember to hit there you might have to hit the bell if you want to be notified of our live stream
we'll be 1500 feet up we'll go right up to two meters not with this we'll be doing two meters on
either the ts 2000 or 705 or something um but this will be going up to six meters on from 40
maybe a bit of 80 as well who knows all right so we'll see how that tcxo mod happened when
we go away in the meantime thanks for tuning in today next video is coming up
all the best and i'll see you next time bye for now cheerio
