Speaker 1 (00:00):
We are back in the truck and driving for Day
twenty three. Day twenty three of thirty Days of Ham Radio.
Yesterday we talked about some two twenty repeaters and it
was disappointing that I wasn't able to reach anybody. But
that's something I'm going to be focusing on a little
bit more for future videos, so you guys stay tuned
for that. Today we're driving up and we're going to

(00:21):
meet a gentleman who invited me out to his house
a few weeks ago. This was before he knew about
my thirty Days of Ham Radio. He had emailed me
and asked if I ever did anything with microwave. He
asked me if I owned an icon Ic nine oh five.
My answer is no, I don't own one. And he said,
and I told her, I said, no, I've never done

(00:42):
anything with microwave. I've studied it a little bit, I've
read about it. I've never actually done a microwave transmission,
and I do not own an Ic nine oh five.

Speaker 2 (00:51):
And he said, well, let's change that.

Speaker 1 (00:53):
Why don't you come out to the house and I'll
show you through this through my microwave setup and we
can do some transmissions and whatnot. And then I replied
back to him right about the time. This was last
month sometime that he first emailed me. And then I
replied back to him right about the time I started
this thirty day challenge, and I'm like, Hey, what if
we do this as one day of my thirty days

(01:15):
of ham radio. And he's like, great, that is great,
let's do that. So we are headed out today to
his home qth that he invited me to.

Speaker 2 (01:24):
We're going to set up.

Speaker 1 (01:25):
An IC nine oh five and I believe that he
borrowed a second radio from a friend of his. Try
to look up his call sign real quick WA sixter
MDI is the gentleman we're speaking of right now now.
I spoke to him. He was one of the stations
on the air during my two meter sideband event when
we joined the Chaos Net. We were looking for the

(01:46):
sidewinder on two net, which was about a week ago
at the time of this recording, and he was one
of the persons. He was the first person to come
back to me and he's like, oh, I didn't know
you had two meters sideban. I was like, yeah, I'm
on my ninety seven hundred. We talked a little bit,
and of course made that video. So he's out there
on and I don't know if he was on his
IC nine oh five at the time or not, but
we're gonna go out here and do some microwave work.

(02:07):
As I said, he burrowed a he's.

Speaker 2 (02:10):
Burrowed a second radio from a friend.

Speaker 1 (02:11):
So he's gonna drive down the road and we're gonna
make a microwave I think he said on ten gigahertz.
We're gonna make a ten gigahertz phone contact. I'm gonna
be on his radio, he's gonna be on his friends radio.
We're gonna do it walk through and just kind of
look at everything. So let's go thirty days of Ham Radio.

Speaker 2 (02:27):
Thanks for joining.

Speaker 3 (02:28):
Yeah, what I wanted to do. I've been through the trains,
have been through the sailboat's been through the airplanes. Obviously
he did that professionally, So the next thing was the
Ham Radio. So what I wanted to do was to
be able to get on one sixty through twelve ninety
six from the house. So I put a closed loop
anten up that covers one sixty through six and that

(02:49):
I covered that with an icon seventy three hundred and
a little als six hundred over here. I got the
ninety seven hundred that covers two meters four thirty two
twelve ninety six. Missing was nine twelve ninety two twenty.
So I got two transverters. This one is nine oh two,
it's twenty five wats. This is two twenty it's one
hundred wats. Both from Q five. They come down and

(03:12):
go into the go into the seventy one hundred icon.

Speaker 1 (03:16):
Something I have not seen before is you're telling me
that that's both a transverter.

Speaker 2 (03:20):
And an amplifier.

Speaker 3 (03:22):
No, what's it takes ten watts in on ten ten
meters and the power output in this one is twenty
five wats. And this one's a hundred watch. It's a
transverter with an amplifier built built into it.

Speaker 2 (03:33):
I've not seen that.

Speaker 3 (03:35):
If you look on the Q five products out of Florida,
that's where that comes from. He does an excellent job.
See Originally the background on that, as I understand it
was that down East Microwave and Q five apparently they
decided to spin off the lower frequency stuff up through
twelve ninety six. So Q five Products handles everything up

(03:57):
through twelve ninety six and then on east microwave does
everything up to what is it forty seven gig That
is how high they go. That makes any sense?

Speaker 2 (04:06):
Sure?

Speaker 3 (04:07):
But now the rest of the gear. Now what we've
got going on is an Icon nine oh five. Now
what happens with this This control head looked very similar
to the seven oh five. Yes, and what they do is,
I've got twelve volts going to that and the output
goes through a Cat six cable. I think you were
on what was it with ray Novak and he mentioned

(04:27):
something about the fact that it's power over Ethernet. Yes,
does that make sense?

Speaker 4 (04:31):
Okay?

Speaker 3 (04:32):
That goes into an RF deck this little guy right here.
Now all of that is handled remotely into this RF
deck which is two meters four point thirty two and
twelve ninety six That is ten watts. Then it has
two point four gigahertz and five point seven and that

(04:53):
is two and a half wats in each one of
those bands. This antenna is an M squared antenna. It's
basically a yaggy and a can on two point four
over on the backside. Over here is the transver that
comes from my common that takes ten gigaherts which is
fed in off this antenna directive systems. That's a dual

(05:14):
feed antenna for ten gigaherts and five gigaherts. So what
happens is that they put out two and a half
watts on two point four and five point seven and
then a half watt on ten gigaherts, and that has
a dual feed horn. Now I've got that set where
it's over horizontal. On top of this is one of

(05:35):
the M squared loops for two meters and also for
four point thirty two, and that's the output being fed
off of the back of the icon box here. And
so what will happen is that when I'm on a
hilltop of this thing, I can actually take and operate
everything from two meters through twelve ninety six off those
two antennas, because the four thirty two rig also loads

(05:57):
up on twelve ninety six and then five what is it? Yeah,
five point seven and ten gigahertz and two point four
at the back end of it.

Speaker 2 (06:06):
You called that one semi portable.

Speaker 3 (06:08):
Semi portable. Yeah, what I've got to do, I've got
to I can disconnect the piece of PBC that's on
the side here facing us that coinks off. I take
the Directive Systems dish off and I can throw it
in the back of the truck. This one is much lighter.

Speaker 5 (06:22):
Yeah.

Speaker 3 (06:23):
Now this is fed into the ICOM seven oh five.
This is the ICOM dish and what it has on
the back end is a down east microwave transverter. It
comes in on ten gigaherts and goes out on two
meters ten watts input and it uses the IF at
one hundred and forty four on the top of this
up here, they use a ten megahertz reference source. That

(06:47):
is a Leo Bodner reference source which has input to
the ten gigahertz box to the transverter. And what that
does it gives us an extremely stable signal. Additionally, there's
a little push to talk circuit back here because this
transverter pulls sixty five milliamps and the seven oh five
can only handle fifty milliamps. So I've got that little

(07:08):
interface in it so you hear when I click it,
you'll hear a click. This is more portable than the
other one, obviously. Yeah, it does a pretty good job.
This is the Icon antenna and I've got it configured
for horizontal configuration, which is what we use here in Texas.
There's a group called the North Texas Microwave Society, and
what they do is first Saturday of every month we

(07:28):
have a m AD or a Microwave Activity Day and
a bunch of guys go running around the countryside at
either portable operators. I gravitate to the hill over here
in Roanoak and I've got a little site up there
next to the water tower. I get up there and
get on the air. Most of your microwave contacts, at
least here in North Texas A or horizontal and B.
It's done on CW. And what they do they exchange calls,

(07:51):
grid square and signal report. Okay, and it's pretty interesting.

Speaker 2 (07:57):
Is it always on ten gigahertz? No?

Speaker 3 (08:00):
I can you know? I can do two point four,
five point seven and ten. Some of the guys you're
playing around with twenty four gigahertz now, and they also
go up to what is it forty eight? Forty seven
or forty eight? Yeah, I didn't even know we had
a handband up there.

Speaker 2 (08:14):
Yeah. I think we got some higher than that.

Speaker 3 (08:16):
I know we do.

Speaker 2 (08:17):
There was a Microwave Update.

Speaker 1 (08:18):
Conference that took place in North Texas here like four five,
six years ago.

Speaker 2 (08:22):
Yes, sir, I attended that, did you, and recorded a
bunch of sessions with those Some of the stuff those
guys are doing is just crazy.

Speaker 3 (08:28):
Yeah, well they it gets expensive and a lot of
times up until this nine to oh five came out,
you had to be a machinist and also a homebrewer.

Speaker 2 (08:36):
What do we get We're going to do some contacts, right.

Speaker 3 (08:39):
Yeah, go ahead, and you want to keep that thing
going or what I can do? Let me get a
glass of water. We can we can package this thing up,
throw it in the back of the truck, take it
over to the park, set it up, and then you
can come back over here and I'll show you how
to run this thing quarter mile from my house. And
what I'm going to do is I'm going to give
you a call and I'm to have you go over
to my place and let you hear the other end

(09:00):
of it.

Speaker 2 (09:00):
Okay, okay, okay, k C five h.

Speaker 3 (09:03):
W B from W A six m B I portable
and Trophy Club on Tim Gigger.

Speaker 4 (09:07):
It's over over all.

Speaker 1 (09:09):
Right, do that one more time. I'm gonna set the microphone.
I'm gonna set the microphone next to the ant that
I heard click. Okay, all right, perfect, okay, So you
want me to walk back over there, can you?

Speaker 4 (09:18):
Okay?

Speaker 2 (09:18):
Yeah? Sure the door you know, if you're coming. Okay,
Casey five h w B you hear me?

Speaker 6 (09:23):
Fine, okay, all right, go ahead and come back to me.

Speaker 2 (09:26):
Sure, okay, down.

Speaker 6 (09:35):
That sounds just fine to me, Casey five h t
b B.

Speaker 4 (09:38):
Okay, but let's just have a contact on.

Speaker 6 (09:42):
On k Okay, Yeah, yeah, sounds good. It sounds sounds really.

Speaker 4 (09:48):
Clear, fantastic, are like that? And Julia Alba over over again?

Speaker 2 (10:03):
Okay.

Speaker 1 (10:04):
Also also five and nine and Echoa Mike thirteen as well.
Juliet Alpha. What's that?

Speaker 4 (10:09):
That's the last two? That's the last two dridge is
the grid square? Look on the well, I'll show you
on the radio. It actually gives you your grid square
on a print out around the screen of the nine
oh five and also on the seven five. I'll show
you when I get back over there.

Speaker 1 (10:24):
Okay, Okay, I was yeah, I was thinking in four digit,
four digit grid square terms, and I thought Juliet Alpha
was something else you were talking about.

Speaker 6 (10:33):
But yeah, I know what you mean.

Speaker 1 (10:34):
Okay, good, Yeah, I don't see it on the screen,
so it'd be nice to know where that is as well.

Speaker 4 (10:38):
Okay, yeah, it's it's in the menu in there, and
I will be glad to show that to you and
want to get don Okay, you got all you need
for the video?

Speaker 1 (10:45):
Yeah, I think we are good. This is this is great.
I really like watching the screen come through and take
ten gigahertz.

Speaker 4 (10:52):
Yeah, exactly what happens is that I'm gonna I'm gonna
shut down and git back your way. You just stay there,
stay in the shade, and I una shut this thing
down and head back.

Speaker 6 (11:02):
Okay, sounds good. Case five HBB, thank you.

Speaker 5 (11:08):
We should be hearing the beacon on two meters.

Speaker 6 (11:12):
Two seventy nine.

Speaker 5 (11:15):
Yeah, two eighty.

Speaker 3 (11:31):
All right, now let's try nine o two okay, and
that would be slipping the switch here.

Speaker 6 (11:36):
Uh huh.

Speaker 5 (11:46):
This one and the twelve ninety six one are keyed together.

Speaker 2 (11:49):
Oh so that's nine oh two dot five.

Speaker 7 (11:55):
Nine nine three dot nine three five o five Oh yes, yeah, okay.

Speaker 5 (12:15):
That's a twelve ninety six beaker, gotcha. That isn't what's
in conjunction with this.

Speaker 2 (12:22):
Now it's hystereo.

Speaker 6 (12:25):
Okay, Well, he's got a little bit of a warble.

Speaker 5 (12:29):
These are all located in the tower.

Speaker 3 (12:31):
Of the Texas Women's University up in Roanoke.

Speaker 2 (12:34):
Gotcha gotcham dent up in Denton? Yeah, yeah, yeah are
they are? They owned and operated by the Denton Club
and TMS and oh okay, oh it's their stuff. Okay, yeah, okay.

Speaker 3 (12:44):
That was fun.

Speaker 1 (12:45):
That was an enjoyable day of HAM radio. Those last
that last little blurb there where he was showing me
the two meters and four thirty two beacons. He was
we were talking about some microwave stuff in that North
Texas Microwaves Society. He said, they run beacons on the
VHF and UHF bands so that you can basically the

(13:07):
band being up doesn't work the same way in VHF
UHF as it does in HF, but you know you
can you can tune your station and point it towards
the beacon and Denton if you're in the area, and
you can monitor it and make sure everything's hearing correctly
and that kind of thing. So it's it's always good
to check propagation and check just overall general setup if
your received signal is working.

Speaker 2 (13:28):
The way it should.

Speaker 1 (13:29):
So special shout out to Dick Melcher Wa Sixter MDI
he's the one whose house we were at today. That
was a fun time. Never had the opportunity to work
any two point four or five gigaherts voice transmissions, let
alone ten gigaherts, so working ten gigaherts today was really cool.
So thanks thanks again, North Texas Microwave Society. I'll find

(13:52):
a link to their website in the and I'll put
it in the description below as well, and probably gonna
be doing some stuff with them, he said the first
Saturday they get together every month, so I might try
to do some stuff with them in the next coming
months and just do some more videos about that aspect
of amateur radio that I have done very little with myself.
So that was really good and I hope you guys

(14:12):
enjoyed that. Let's read some donations real quick, okay. Ending
today with donations, we are up to four eight hundred
and five dollars for a total of eighty nine donors.
After this much time and this many views on this
many videos, I kind of thought we'd have more than
eighty nine donors. Maybe some of you guys are waiting
till the last minute. I don't mean to sound ungrateful,

(14:33):
but I was really kind of hoping to get a
bigger number going by this far into the series. We're
more than two thirds of the way into the series
right now, and I was obviously set a goal for
thirty thousand dollars. We haven't even gotten a third of
the way there. So again, we're gonna do a live
stream at the end of this probably the first Sunday
of October. We're gonna do a live stream. We're gonna

(14:54):
do a recap, we're gonna talk to this. I'm gonna
try to get Steve k five Ata on there. We're
gonna do a thing. So if some of you are
the last minute, then okay, no problem with that. And
again I don't mean to sound ungrateful. I just was hoping.
I was hoping to raise more money for the Teachers
Institute than have anything to do with me or my numbers.
Has to do with the Teachers Institute. But we had
four new donors yesterday and raised a total of one

(15:14):
hundred and seventy five dollars just yesterday. Again, these donors
are as of last night, and the only note was
in memory of Marvin and Juanita McCullough from twenty twenty two,
so thank you for those donations. Go to a dobrl
dot org forward slash thirty days to make further donations
to the A. Doublerl Teachers Institute.

Speaker 2 (15:33):
And we'll see you guys tomorrow

Cardiac Cowboys

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
