I use the Kenwood D-72 for Sats. I currently use a 2.5 to 3.5 audio cable
from the radio to a digital recorder and then plug a set of Sony headphones
into the recorder. Be warned you need to follow the following procedure or
the radio will "freak out". If you unplug the audio cable after radio is on
it affects it as well.
1. Plug everything together
2. Power on recorder
3. Start recorder
4. Power on radio
5. Work pass
6. Power off radio
7. Power off recorder
Hope that helps I am attaching a link to the audio cable I use and a picture
of my set up below. Hope this helps hope to catch you on a pass!

Hi!
Tomorrow (Saturday, 16 December) morning, I will head out to western
Arizona and operate on the DM23vx/DM24va grid boundary. This spot is
north of the AZ-72/AZ-95 junction, north of Quartzsite and southeast
of Parker. I plan on being here from mid-morning into the afternoon,
working FM, SSB, and - if available - packet passes.
Sometime in the mid- to late-afternoon, I am probably going to drive
north to Kingman and the DM25/DM35 grid boundary for some passes up
there. Ideally, I might be able to get in on some of the XW-2 "train"
for the east coast, but would stay there for a couple of hours before
returning home. If there is snow in or around Kingman, I will not
head this way, and may look at an alternative loop for the drive home
(i.e., returning via Yuma AZ and the DM22/DM32 boundary near I-8).
For the night owls, I might still be up for at least one AO-91 pass
late Saturday evening. For that pass, I might be home at that point,
but I will make note of the AO-91 pass times to make sure I don't
forget them.
While on the road, I'll run APRS from my car as WD9EWK-9. There should
be decent coverage for most of my planned road trip on sites like
(among a few others) http://aprs.fi/WD9EWK-9 . I will also use my
@xxxxxx Twitter account to send updates, and - depending on the mobile
data network - pictures from where I am operating.
After the road trip, I will upload my log to Logbook of the World.
For those that would like to receive a QSL card for a contact with me,
please e-mail me directly with the QSO details. If you're in the log,
I'll get a card out to you.
73!

Actually, why wait till Experimental Wednesdays.
1200 baud AX.25 packet is legal uplink for PSAT's 28.120 USB uplink and
435.350 downlink (unless I misread the rules). SO I will say that such
experiments are welcome on PSAT as long as there is little to no other PSK31
activity in the 1000 to 2400 Hz tones on the air at the time of the
experiment. Doppler during a 1 second packet burst will be
insignificant....
OOPS, insignificant, but critical. One has to pre-shift your uplink so that
your downlink does come down at the standard 1200 baud AFSK tones of
1200,2200 Hz. I guess the key there is to transmit your PSK31 "pilot"
signal for a few seconds at say 500 Hz on the uplink, adjust your uplink
Transmitter RF to verify you see it at 500 Hz in the downlink and then
transmit the packet.
I'd love to see this transponder used more. But again, the uplink is shared
with terrestrial PSK31, so share the band. You can verify a clear band by
looking (or listening) in the downlink if there are ANY PSK31 users in the
1000 to 2400 Hz bandwidth prior to transmitting.

Use the APRS Object for a SHELTER. Just one packet can contain the
position, time and date of the report, and up to 47 bytes of useful info
such as 1) head count of staff 2) head count of victims 3) electrical power
4)drinking water 5) more supplies needed 6) need critical assistance.

They do. APRS is currently on 3 sateliltes... PSAT, ISS and PCSAT and soon

We have it. See the SATT4 single card APRS transponder. We invite every
school or university that is contemplating a CUBESAT to consider using this
transponder for their command and control which also provides the APRS
transponder as well. Cost is under $300 or so.

Content-Type: text/plain; charset="UTF-8"
Hi everyone,
Yesterday (Thursday), while on my whirlwind FN87/77 grid activation trip, I
ran into a frustrating thing with my TH-D74.
Wanting to use (Bose QC15) noise cancelling headphones for my downlink
audio, I used a 2.5mm male to 3.5mm female adapter pigtail to take the "SP"
audio off the side of the radio and feed it into the headphones, while
using my VX-8GR for full duplex transmit (for AO-91).
The problem: every time I plugged the pigtail into the side of the D74, its
frequency would change and the ability to QSY back to the intended downlink
frequency would be severely limited or even prevented altogether. I wanted
to be in VFO mode, for instance, and plugging the pigtail into the speaker
jack immediately took me to memory channel recall mode, on an apparently
random channel, and then prevent the selection of another memory or a
return to VFO mode.
So I thought I'd fix that problem by locking the radio with the long press
on the "F" key. No change in behaviour. The frequency change still happened
every time I plugged in to the speaker jack. The problem sometimes occurred
immediately upon plugging in, but sometimes it would work fine on VFO mode
for a few seconds before the changeover.
I will continue to fiddle with it to set put exact behaviors in varying
circumstances. I'm just wondering if anyone else has experienced a similar
problem.
What I ended up doing was going without headphones altogether and just
listening to the D74 out of its own speaker, in the wind, with feedback on
the uplink when I transmitted. Sorry about that mess!

Winter has set in for Chicago before I had a chance to get an antenna put up
for 28.120 MHz. But I've been occasionally monitoring the 435.350 MHz
downlink. PSAT's PSK-31 beacon on the downlink is strong (a lot stronger
than the 145.825 downlink).
I've been using FLDIGI (it's free) for receiving PSK-31 in my shack. Besides
the beacon there is plenty of empty bandwidth during a pass on the waterfall
display. Give 435.350 a listen to start getting used to the characteristics
of this satellite.

An excellent recommendation. I'll have a chance, I bet, after the holidays
to look into testing with NBEMS via satellite. We have a few months to get
ready ... I retire at the end of March 2018. I'm keeping my nursing license
active when I retire so I can volunteer for disaster relief projects. When I
go out I'll need one of these :-)

? ?I have only made a few contacts on the FM birds, so a very newbie.
Ramping up quickly with my Christmas wish list for linear birds. If SSTV has
run its course, please do not stop all together. Maybe can rotate different
weeks of the month for experimental day. I have only heard one SSTV picture
on the bird a few weeks back but remember it well. Still remember my 1st HF
SSTV contact Ivory Coast. I think keeping SSTV some weeks may get a few more
people interested in satellites, just like ISS SSTV. Sure wish the US would
send as many ISS pictures as the Russians. I do not understand that either.

Not to worry. SSTV from space is one of our best crowd pleasers. And it is

The current configuration of ham equipment on the ISS has the computer and
transceiver that are SSTV-capable in the Russian segment of the ISS. A
standard amateur radio configuration for everyone on the ISS is under
development. See www.ariss.org.
Welcome to some of the coolest stuff in ham radio ... amateur radio in space!

Stan,
We normally sell embroidered caps at the Dayton Hamvention. Inventory not
sold at the Hamvention is then sold on the AMSAT store.
The hat was very popular this year; the few not sold at the Hamvention
went quickly from the store.
If you?re not going to Hamvention, pay close attention to the store in
late May.
