been licensed since 1974 and in 1983 in preparation
for the first ever ham radio operation from space
he was responsible for setting up and operating
the worldwide retransmission of the space shuttle
air to ground communications from the Goddard
amateur radio club station WA -3NAN. The initiative
provided a critical conduit of information to
hams attempting to contact astronaut Hams before
the internet came along and Frank now serves
as the amateur radio on the International Space
Station International Chairman. He has a bachelor's
and master's degree in aeronautics and astronautics
from Purdue University and his career in aerospace
spans four decades within NASA and in private
industry. And he was just named the 2017 Dayton
Hamvention amateur of the year. So congratulations
on that, Frank. Uh, we're going to try to talk
about that on a show coming up in May, actually,
uh, with all the, uh, the award winners and,
and thanks to Skype. Uh, I didn't get to tell
you about that before we went to the air, but
congratulations and thanks for coming on the
show tonight. Thank you very much, Neil. And,
um, um, pleased to be part of HamTalk Live. Well,
I'm glad we were finally able to work it out
and we had an opening tonight and we kind of
threw this together at the last second. So I'm
thankful for that and thankful for you giving
up some time to share with us tonight about what's
going on up at the International Space Station.
Over on Newsline, I've done some stories with
you and with Rosalie K1STO about some of the
updates that are coming along. And one of the
last ones was about the new JVC Kenwood TM -D710
that's been donated and is going to go up to
the space station. And then all of a sudden we
hear, oh, wait a second, the Ericsson's back.
So. I've seen a lot of people kind of saying,
wait a minute, I thought we were replacing the
Ericsson with a mobile and replacing the old
handheld. But then all of a sudden the SpaceX
rocket shows up the other day with a replacement
Ericsson. Can you fill everybody in just on what's
happening with all of the equipment that's on
board the International Space Station and being
planned for the space station and how the process
is proceeding to get that new mobile rig up there?
Sure thing, Neil. Yeah, a lot of things are happening.
You know space station is a very dynamic environment.
There's a lot of research going on and got a
Thank the ISS crew members for the time that
they are giving to the Eris program because you
know, frankly the research is getting more and
more every year and They're getting busier and
busier and yet they continue to support us. So
that's great So on to your question relative
to the JVC or relative to the Ericsson radio
so when the Ericsson VHF handheld failed it was
a lot of dialogue as to whether we should expend
the time to Have it replaced and how much effort
was going to take to to make that happen or you
know whether that would divert time from our
development of the of the new Interoperable what
we call the interoperable radio system, which
is the Kenwood TM the JVC Kenwood TM D710 coupled
with the interoperable or multi -voltage power
supply that we're developing So as it turns out,
let me just say that You know, we have a we have
a D710 in the Russian side in the service module
And we have the systems in the Columbus module.
And the primary system that does packet is in
the Columbus module. So our first order of business
was to get something back on the air in the Columbus
module. And we still had the 70 centimeter radio.
So that got installed. In the meantime, we learned
from NASA that it wasn't going to take very much
effort to basically go through the recertification
process and we ran some tests with the Ericsson
VHF radio and got it, actually I was kind of
astounded we got it on SpaceX 10 and got it up
there as quickly as we did. The thing we wanted
to do is in the interim utilize VHF in Columbus
module because the two things one is if we use
the VHF system in the Russian segment then the
crew members have to float all the way over to
the other side of space station which is you
know 100 yards basically to use that radio and
then come all the way back again which impacts
their ability to do research and so the other
part was that the schools aren't very as comfortable
and operating on 70 centimeters with the increased
Doppler. So we just thought that if we can get
this up there in the interim, which we did, and
get it on SpaceX 10, which we did, that it would
provide that interim operations so that the crew
members would be served better and the schools
would be served better. Yeah, let me jump in
there just for a second because I've gone through
this once and so I understand but some of our
listeners may not understand what that Doppler
shift means when it comes time to make a contact.
So what's happening is you're actually having
to change the operating frequency continually
while you're in the middle of the contact. That
is correct and you get the amount of Doppler
shift for For two meters is a lot less than it
is for 70 centimeters, you know, it's basically
three times more on 70 centimeters so and Between
that and between the fact that there's a number
of other factors, of course you know 70 centimeters
is a weaker signal from space and so all of that
kind of came together and and and the schools
not being prepared to do especially the ones
that were coming up they weren't prepared to
do a 76 centimeter contact they'd been preparing
for a two meter contact so so we just kind of
felt that was the right thing to do you know
we had a lot of i will say this we had in the
background a lot of debate on that topic But
as it turned out, it was not a big deal to make
it happen. I have to give Lou McFadden, W5DID
and Kenneth Ransom and 5VHO a lot of credit for
making that all happen behind the scenes. Okay,
very good. So we've got the new Ericsson VHF
rig up there. So the UHF can be put back away,
back on VHF until The Kenwood gets there so update
us on Where things stand with the Kenwood mobile?
Okay, so as I said what we're Developing is a
system that can be interoperable across all of
space stations so we're building a multi -voltage
power supply and We've been working with JVC
Kenwood on a significant modification of the
Kenwood radio of the D710 to operate most efficiently
in space and on space station. So the idea is
what we're planning on doing and what we are
working on is to certify this system to operate
in all segments of space station. Right now we're
operating an Ericsson radio in the Columbus module
and a Kenwood radio in The Russian side in the
Russian service module Training is different,
you know operations are different and things
like that and and and if there's a failure it's
hard to move things around so the idea is we
want to have a a System that can be operated
anywhere Where we are on that is we had a very
big and very positive test at the NASA Johnson
Space Center just a couple weeks ago with the
prototype of the power supply. And that prototype
passed all of the requirements on the Russian
side, the US side, and the European side. So
from that perspective, What we have now is a
system that we feel confident that we can start
building, actually buying the parts and actually
building the power supply. Once we have this
power supply done, and we have it certified,
then we can work towards flying it on Space Station.
And the reason for all the different voltages
is because The Russian modules have a different
power standard than the American side. That is
correct. So the Russian side runs off of 28 volt
DC, and the US side runs off of 120 volt DC.
And so we have different potential, different
inputs, different connectors. depending on where
you are in Space Station that you would use for
both 28 volt and 120 volt DC. The other thing
is Space Station can't handle mobile rig and
that's been our biggest issue is that we need
the 13 .8 volt DC outputs and so what we've got
now are four output capabilities that can do
a lot of different voltages, 28 volt 13 .8 and
6 volt to support our SSTV system and we're gonna
have four ports on this power supply that are
USB 2 .1 amp ports that we can use for tablets
and things like that in the future. So this system
is being built for today's system as well as
the future system and as you know in any situation
having the ability to plug in systems is critically
important. And as an example, our ham television
system has gone up and down, shut off and turned
back on because another experiment is using the
same plug, the same receptacle as we are and
we have to switch it out. So the idea of this
power supply is to be able to focus all of the
ham radio equipment into this power supply and
not have this turn on, turn off situations that
we have right now. Excellent information and
I think that gives people a perspective on the
challenges of getting this done technically.
So let's talk about some of the challenges financially
of making this happen. So why is it the cost
so high to get this radio certified even though
you know the radio has been donated? It's the
certification and getting this power supply build
and everything So why is cost? So high on that
and then Tell us how people can Contribute to
that cause to to to get that cost met so that
we can get this thing up in the sky Okay, sure.
Yes your Absolutely correct. It is not cheap
to fly equipment on a human spaceflight mission
like Space Station. I get a lot of people asking
me, we'll provide you the radio and just fly
it. And it's like, no, no, no, we can't just
take something up there. For starters, we need
to make sure we have the right voltages, and
that's why we're doing this multi -voltage power
supply. But the other part is, There are a lot
of, you know, space station is the equivalent
of a house, you know, but it's on orbit and there's
a lot of safety requirements that need to be
met. I mean, literally thousands of requirements
that need to be met and basically hazard reports
that need to be generated and tests that need
to be run to validate things like making sure
that the temperature of anything in space environment,
which is different than on the ground, because
in microgravity you don't have convection, that
the thermal doesn't actually cause a heating
that would actually be above what would actually
hurt an astronaut. And then there are other things
like sharp edges and electromagnetic compatibility
and off -gassing, you know, basically if you
took, you know, some of your magic markers, if
you will, you know, you can smell those things.
Some of those are off -limits on Space Station
and some of the materials are off -limits on
Space Station, both from a flammability perspective
as well as from an off -gassing perspective.
So all of these things need to be factored in
and while we have experts like Lou, myself, Mark
Steiner that have done this kind of stuff in
the past, we need to have an expert in there
to help us with the hazard reporting. An expert
in safety for human spaceflight missions is not
a cheap activity. Just to give you an idea of
the costing of hardware, let me just say that
we just did a cost analysis, not a cost analysis,
we actually did a cost inventory. for the multi
-voltage power supply. Now that NASA has said
that what the prototype we've developed would
satisfy the requirements from an EMC perspective,
electromagnetic compatibility perspective, we've
put the whole parts list together, both for the
mechanical and the electrical pieces. And bottom
line for the whole system, for one unit, just
for parts, is about $5 ,500. Now, what you need
to understand is, think about what we're trying
to build here. What we end up building are 10
units, not one, but 10. We need two flight units
to go into the modules. We need one in the Columbus
module and one in the Russian service module.
We need two backup units, two flight backups
in case one of them fails. We need training units.
in Russia and the United States. We need testing
units in the United States and Russia. And we
need engineering evaluation units. If there's
a failure or something like that, we need to
have a very high fidelity unit for that. So bottom
line is what we've come up with on the order
of 10 items that we need to build. Then we have
the certification and the testing. All of that
gets into the certifications on the order of
between $80 ,000 and $120 ,000 just by itself.
It all adds up. It sounds like a lot of money
because it is. What I would say is that every
little bit helps. Basically, we have right now
an incentive for anyone that donates and you
can go to the AMSAT .org website. You know, www
.amset .org. If you go on there on the right
-hand side, there's a donate button for Eris.
If you donate $100 or more, we will provide you
an Eris Challenge coin, one of these little coins
that is a memento for your support to the program.
If you are in a small or large business, they'd
be interested in giving us a grant I would suggest
they contact me directly and I will work with
those individuals but I will say that every little
bit helps and I want to remind everybody that
you know when we produce and build and fly these
systems what we're going to have is a much more
powerful radio system that's on the Columbus
module than we have today 25 watt versus what's
up there now, which is a five watt radio. So
it'll be much stronger. The packet system will
be much better. We're gonna have voice repeater
capabilities that will be, we can use key down
because we've modified the radio to handle the
thermal requirements. Key down continuously,
if you will, for the repeater. We're going to
have a lot of new capabilities on there and much
more stronger system that hams can use as well
as the voice capability for the skulls. Does
that help? That does. So go to amsat .org and
click on the link there for donate to ARIS and
help out as much as you can and again if you
know someone who can facilitate a larger grant
you can contact Frank directly and how should
they get a hold of you? Best approach is use
my call sign KA3 HDO And you can either use that
AMSAT .org or you can use Verizon .net. Either
one of those will work for me. All right. Very
good. There you have it, folks. That's how you
can help get things improved and up and running
on the International Space Station. And the schools
make those contacts. But people are making contacts
with the space station all the time with digital
modes and an occasional contact or two. So, you
know, it benefits us all to do that. Appreciate
all that information and we do need to stop and
take a break here. So we're gonna do that right
now But we'll come back and we're going to take
your calls. So Give us a call 812 net ham one

search for HamTalk Live and we're also now on
Instagram so it's time for your calls if you
have a question call 812 net ham one eight one
two six three eight four two six one or you can
Skype your question Our username is ham talk
live and we have a couple of tweets So we'll
get to those in just a second but first Frank
you mentioned that you want to talk a little
bit more about some things coming up on the financial
horizon Yeah, I just want to mention that Coming
around the date and time frame. We're going to
be making some announcements of some additional
opportunities for folks that do some more bigger
donations than $100 so realize that you know,
not everybody can afford that but if for those
that might and and really want to give to the
to this cause and and help image radio in space
station on space station help the schools and
help the ham radio community in general that
Will have some some special opportunities for
for folks and we'll make those announcements
As we get close to Dayton All right, very good.
Well, we've got a couple of tweets here so that
we'll start off with but If you want to give
us a call, it's eight one two net ham one eight
one two six three eight four two six one Our
first tweet comes from KM0MMM, and he wants to
know, did the ISS to school contact on March
1st fail? He only heard the ISS, NA1SS, and didn't
hear the school. So did that work out okay, Frank?
Yeah, I can explain that. Yeah, we did have a
failure. We had... Basically, with all of these
changes that are happening, let me just say that
we're operating in the Russian side right now
with the Kenwood radio. With all these changes
that are happening in the crews, one of the things
we have done was we asked the crew to program
the radio in the service module to make it easier
for them to operate. We're a little bit of some
glitches that went along with that. So it was
basically that contact failed and we're working
towards giving them an opportunity again Okay,
very good and Eric into KOJ is Gonna call but
he lost his voice get his tweets here Eric wants
to know has there been one astronaut or cosmonaut
Who was more active with heiress than? Some of
the others Well, that's that's a very good question
and let me just say that just like everybody
on earth Every each individual is different There
are and and even within hams. We know this even
within the ham community you have different interests
Some people do a lot of operating, some don't.
Some like to get into experimentation, some don't.
The same is true with the astronaut corps, astronaut
and cosmonaut corps, if you will. Some are extremely
excited about talking to hams on the ground.
Examples of that are Mike Fink, Doug Wheelock,
as many of you know those names, Bill MacArthur.
Going back in time, Owen Garriott, Ron Parise,
those individuals are really dedicated ham operators
that really want to get in and talk to people
on the ground. Some of them aren't and are just
interested in school contacts. And then others
don't even get their license. So it depends on
the individual. And and I'll say even some Have
gotten their license and will do things one one
space station to our duty or there is called
expedition and the next opportunity they might
not or You know, I'll use Mike Fink as an example
He got a good taste of it the first time and
he got a better taste of it the second time in
other words He did more I will also mention that
you know, both Mike Fink and Doug Wheelock are
gonna be flying again in the future and so we're
looking forward to them flying again and I'm
sure it will be I've got the opportunity when
I was in Russia to talk to Doug Wheelock and
he's pretty excited about about his next opportunity
Great and Eric also wants to know about QSL cards.
Are there QSL cards? available for QSOS? Absolutely.
If you go to the ARIS website, ariss .org, we
do have a link there on how to get your QSL card.
And you can get one for digital communication,
slow -scan television, a reception, or a two
-way with the crew members. So you can do that.
ARL is handling QSLs, some of the ARL folks volunteer
to support that, but it's on the ARS website.
All right, very good. Thanks for answering those
questions. And that's all that we have for right
now. So, lines are open. Give us a call. 812
-NET -HAM -1. 812 -638 -4261 if you have a question
or comment about the Ham operations on the International
Space Station. Frank Bauer, KA -3 HDO, is with
us tonight, the International Chair, and he's
been flying all over the globe down here, and
he's getting ready to take off again, so we're
glad that he was able to squeeze in some time
with us this evening. So let us know, 812, net
ham 1 is the number, and Eric says, thanks, and
congratulations on the award. So again, we're
going to talk about that a little bit more in
May. But yeah, congratulations on getting the
Dayton Hamvention Amateur of the Year. Thank
you. I will say that I was shocked and humbled
at the same time when Michael Coulter gave me
the call and let me know. I still, I'll say I'm
still in shock and humbled. It still hasn't worn
off and it won't, I think, till way after Dayton.
It is such an honor. I look at some of the individuals,
some of the individuals that have gotten it are
extremely good friends that I've had over the
years and from the perspective of, you know,
Rosalie White was one of them. K6DUE, Roy Neal
was one of them, the late Roy Neal. And last
year was Joe Taylor, a Nobel Prize winner. So
I just, to even be called and told that I'm receiving
this award is still, I'm wondering if I'm gonna
wake up and it will all be a big dream. Got to
pinch yourself a couple times. Exactly, exactly.
Well, that's great. You've put a lot of efforts
into this and we appreciate all that you've done
and very deserving of that award. So we're glad
that that's happened. 812 Net Ham won. If you
want to talk to the award winning. Frank Bauer
K3 HDO about the International Space Station
give us a call or you can tweet us. We're at
ham talk live So we have a few minutes remaining
in the show. So Give us a call or a tweet While
we're waiting on those to come in I want to talk
a little bit about those school contacts that
those are made on a Fairly regular schedule.
How often are those? Taking place and what kind
of results have we seen from those contacts?
Good question Neil, you know, we are doing about
60 to 80 schools a year I think last year was
last year was 88. So we did a little bit more
than 80 last year and So that represents about
one to two a week, you know usually Number of
weeks will do two and some weeks will just do
one Depending of course orbits are what you know
the physics of orbits are what defines? When
we do these contacts there every one of these
contacts are outstanding and and it just I Will
say that you know I feel very privileged to be
leading such a wonderful dedicated team the heiress
volunteers are amazing and I will say that They
get energized by you know going to one of these
contacts either mentoring or just You know witnessing
one because when you do that you see the magic
of amateur radio coming together with human spaceflight
with with astronauts and and the space programs
and It is magic, and the students are just touched
so deeply. It's something that they never will
forget. And above and beyond the fact that they're
inspired that way, they go through so much in
preparation for these contexts from an education
perspective. They learn about orbits. They learn
about ham radio. They learn about... I was down
in Houston a couple weeks ago for one of the
contacts. Me being a NASA person, both Kenneth
Ransom and I did a Q &A session. Students were
asking some pretty phenomenal questions about
life on Mars and what would happen if this event
occurred and what would the crew member do if
there was some issue on Mars or on Space Station.
They learn a lot from this and they come away
with it with a much better appreciation for what
it's like to work in a highly technical field
in the space program and it gets a lot of them
excited about working in science, technology,
engineering, math, and radio careers, if you
will. 812 net ham one is the phone number we
have time for one more question, so Give us a
question on the phone at 812 net ham one or on
Twitter at ham talk live or Skype us at ham talk
live the School contacts that you know you've
been talking about are great and We were able
to do one spontaneously. We didn't get the scheduled
ones, but fortunately we got a hold of a space
tourist. But what about everybody else? How can
people make a contact on their own? And that
may need to be digital. So tell us how that would
work if somebody just wants to try to contact
the space station. Yeah, the easiest thing to
do and you brought it up is the the the digital
capabilities, you know, we have a PRS and One
of the things you can do this is way I communicate
it to to the students so they understand it is
You know a PRS basically you all know this you
can send a little message up and I I refer to
it as like a Twitter or a or an instant messenger
type message that you know people can send up
to the space station it gets digiped down and
You can receive it back on your radio system
as well as it's on you know on the net on the
network the website where you can actually see
your signal come back as well as everyone else
and and frankly people have Conversations when
space station comes overhead, you know little
ones you can't do a whole, you know big Conversation
but you can send little messages here and there
like you you would a Twitter message or an IM
type of message So, you know, that's the I think
the easiest and frankly if someone wants to learn
You know the complexities of orbits and things
like that. That's a great one You know, another
thing people can do is, on the Ares website,
as well as some others like ISS Fan Club, we
publish when we're going to be doing a school
contact ahead of time, and have all the questions
online. So you can grab those, tune in on 145
.80 with your radio, you know, handheld, you
can hear part of it, but if you've got a little
bit of a game antenna, makes a huge difference,
and pick it up. We also are doing occasional
slow -scan television activities. We're trying
to work with our Russian colleague right now
and doing one in the next month or two, and we'll
provide that information. But there's a lot of
different things you can do, and then when you
have the crew members like Doug Wheelock, Mike
Fink, or Bill MacArthur as examples, doing the
two -way voice contacts are the ultimate. Everybody
wants to do those and we'd love to do them all
the time But it's only those special astronauts
that want to do those kind of things Well, unfortunately,
Frank, we are out of time. But thank you so much
for coming on and sharing all that with us. And
we look forward to seeing you at Dayton. And
maybe we'll talk to you about the award show
we're going to do here. And hopefully, you'll
be able to participate in that as well. So thanks
a lot. All right. Thank you very much, Neil.
And I thank the whole HamTalk Live community.
All right, that is a wrap for this week's ham
talk live. Thanks to Frank Bauer, KA3 HDO, and
everyone out there in cyberspace for listening
and tweeting in. And I invite you back next Thursday
night at 9 p .m. when Rob Massadot, KD1CY, and

the voiceover IP. Hurricane Net. And for a list
