Hi!
I have written a bit about the Alinco DJ-G7T and using it on satellites on
this list over the years. I wrote about using it on AO-92 in both U/V and
L/V modes last year:
http://amsat.org/pipermail/amsat-bb/2018-February/066923.html
Until the past weekend, I had always worked AO-92 L/V with two radios -
transmitting on 1.2 GHz from the DJ-G7T, and receiving the 2m downlink
with my Kenwood TH-D74 (which can also record the downlink). I have used a
couple of different antennas, but have wondered if the DJ-G7T could work
the L/V mode full-duplex like it can work U/V (with some caveats) full-
duplex. Now, I have tried this for myself, and will ask the question...
Can the Alinco DJ-G7T work AO-92's L/V mode full-duplex? Yes.
Before the past week or so, I was aware of the triplexers offered by
Diamond that included a 1.2 GHz port. Those are noticeably larger than the
diplexers from Diamond and other manufacturers, and a larger price tag as
well. I saw something online that mentioned the Diamond MX-37 diplexer,
having one port for HF through 470 MHz, and the other port for 800-1300
MHz. Physically, the MX-37 diplexer is similarly sized with other
diplexers, and it has two coax pigtails for those two ports - coax with an
N connector for the 1.2 GHz port, and a PL-259 on the other pigtail for
use with the lower frequencies. The common port is an N socket. After I
received this diplexer in the mail, I was ready to fit it into my portable
AO-92 L/V station.
I have been using a 10-element 1.2 GHz Yagi for AO-92 L/V in the past few
weeks, and I tie that to the PVC handle of my Elk log periodic. I decided
to tie the MX-37 diplexer to the PVC handle behind the antennas. This
allowed me to connect the 1.2 GHz side of the diplexer directly to the coax
pigtail from the Yagi's driven element. I used a 3-foot/1m length of coax
from the PL-259 connector on the other side of the diplexer to the Elk's
coax feedpoint. From the common port on the diplexer, I ran another
3-foot/1m length of coax to the DJ-G7T.
To keep from causing audio feedback while transmitting, an earpiece or
something like that needs to be plugged into the DJ-G7T. The DJ-G7T uses
a single 4-conductor 3.5mm jack for speaker/mics. To split out the speaker
jack so I can use an earpiece and an audio recorder, an adapter is needed.
I use Alinco's EDS-10 adapter, which provides a 3.5mm speaker jack and a
2.5mm microphone jack (don't need anything in the smaller jack for this).
Alinco also has an EDS-14 adapter, which looks very similar to Yaesu's
CT-91 adapter used with a few HTs (VX-6R and VX-7R, among others) - where
the two jacks are on short pigtails from the 3.5mm plug. The Yaesu CT-91
adapter works fine with the DJ-G7T.
The DJ-G7T only allows transmitting from VFO A, the upper VFO on the HT's
display. I put the 1267 MHz uplink frequency in this VFO, along with
encoding the 67.0 Hz CTCSS tone. I use 5 kHz tuning steps on this radio for
1.2 GHz. I set the volume for this VFO to 0, and tightened the squelch to
the maximum. For the lower VFO (B), I put 145.880 MHz with the squelch left
wide open, and adjusted the volume to a reasonable level using my earpiece.
I used this setup for 3 passes over the weekend. The antennas were a little
heavier with the diplexer on the handle, but I could still control them
with one hand. I held the DJ-G7T, along with the splitter and patch cable
to my audio recorder. I could still adjust the knob for the transmit VFO,
and made some contacts on those 3 passes. It was fun to be able to use just
one HT for AO-92 L/V.
There are some tradeoffs when going from a two-HT setup for AO-92 L/V to
just the DJ-G7T. The 2m receiver isn't as good as with other HTs, certainly
not as good as the TH-D74 I have normally used when working L/V. I heard
some other signals mixing with the AO-92 downlink on parts of a couple of
passes. Of course, the DJ-G7T does not come with a built-in recorder like
the TH-D74. There may have been a little less power going to the 1.2 GHz
Yagi, passing through the coax to the diplexer's common port and then out
from the diplexer to the Yagi, but I still got through. During one of the
L/V passes, I was still able to get through AO-92 transmitting at low power
from the DJ-G7T (rated at 300mW for 1.2 GHz).
I posted some pictures of this setup on the QRZ satellite forum, in a long-
running thread "Where's AO-92???", starting at:

It is nice to see that the DJ-G7T is capable of L/V full-duplex operation,
just as it is capable of U/V full-duplex operation, in line with Alinco's
advertising for the radio - with some caveats. I can now alternate between
a one-radio setup and a two-radio setup for AO-92 L/V. More fun with
radios... :-)

Patrick, I found a Comet CF-416 Diplexer at the superstition hamfest back in
December for $25.00 pretty much just as the one you have (Common--> N
connector the 1.2 pigtail the same and the 144/430 a PL259. Stopping on the
way home tomorrow to get the EDS-10, I don't see the EDS-14 you spoke of
offered anymore.
I see HRO ahs the CF-416W, which is essentially the same:

Hi Rick!
I didn't look for the Comet equivalent diplexer when I had
HRO ship me the MX-37. Looking at the two, it seems like
it's a matter of tradeoffs in picking one over the other
(except for price - the Comet diplexer is $10 more at HRO -
and not clearly in stock at any of those stores). You get
lower insertion loss with the Comet, but better isolation
between the band ports with the Diamond.
Alinco's EDS-14 had been more widely available for a while,
but now it looks like it has been replaced by the EDS-10.
The manager at the Phoenix HRO store was the one that told
me about the Yaesu CT-91 speaker/mic adapter working with
the DJ-G7T, which I confirmed for myself. Alinco's web site
still shows both the EDS-10 and EDS-14 as "plug conversion
cables" to take the speaker/mic jack and split out separate
jacks for the speaker and microphone, where the latest PDF
version of the owner's manual allocates an entire page to
the EDS-14 and doesn't mention the EDS-10.
Do you have a 1.2 GHz antenna of some sort? There are
WA5VJB designs for that band, a Comet antenna sold at HRO
and other stores, and a couple of Yagis available on eBay
(among other options). There's at least 3 of us who work
AO-92 L/V from the DM43 side of metro Phoenix (you can
also hear K7TAB and N7NEV on AO-92 L/V). Other than two
weeks ago when K7YDL was on from DM33, there hasn't been
regular L/V activity from your side of the city. Join us!
Hope to hear you soon on AO-92 L/V. 73!

Hi Yono!
I am using a 10-element Yagi from eBay, from a link in a post
here on the AMSAT-BB last October:

I am sorry it took so long to get the award into the store. We were
trying to wait until we had the certificate designed. In any event, the
item is in the store and you can apply for it now. Those that sent their
applications to me will need to pay for the award (please paste your
contacts in the comments, easier for us to keep track).
Keep in mind that these are not numbered so there is no hurry if you
apply today or next week or in a month. Also be aware, that if you apply
now and also apply for the special AMSAT Satellite Achievement Award
(only 20 of them will be available), I plan on placing it in the store
this weekend. If you order separately, you will pay postage twice. If
you order on the same order, you pay postage once. Your choice.
Certificates will be mailed as soon as we complete the design and figure
the best way to print them.

Patrick, for me the tradeoff was the price. I bought the same Yagi you did,
came this week. I do plan on making a hybrid antenna for L/V. The design I
saw was for 1296, I want to reach out to Kent and see if there are any
significant alterations to bring it down to 1267.

Hi Rick!
I didn't look for the Comet equivalent diplexer when I had HRO ship me the
MX-37. Looking at the two, it seems like it's a matter of tradeoffs in
picking one over the other (except for price - the Comet diplexer is $10
more at HRO - and not clearly in stock at any of those stores). You get
lower insertion loss with the Comet, but better isolation between the band
ports with the Diamond.
Alinco's EDS-14 had been more widely available for a while, but now it looks
like it has been replaced by the EDS-10.
The manager at the Phoenix HRO store was the one that told me about the
Yaesu CT-91 speaker/mic adapter working with the DJ-G7T, which I confirmed
for myself. Alinco's web site still shows both the EDS-10 and EDS-14 as
"plug conversion cables" to take the speaker/mic jack and split out separate
jacks for the speaker and microphone, where the latest PDF version of the
owner's manual allocates an entire page to the EDS-14 and doesn't mention
the EDS-10.
Do you have a 1.2 GHz antenna of some sort? There are WA5VJB designs for
that band, a Comet antenna sold at HRO and other stores, and a couple of
Yagis available on eBay (among other options). There's at least 3 of us who
work
AO-92 L/V from the DM43 side of metro Phoenix (you can also hear K7TAB and
N7NEV on AO-92 L/V). Other than two weeks ago when K7YDL was on from DM33,
there hasn't been regular L/V activity from your side of the city. Join us!
Hope to hear you soon on AO-92 L/V. 73!

ARISS News Release

FOR IMMEDIATE RELEASE
Out of This World Auction Sponsored by ARISS
March 6, 2019 - The ARISS-US team (Amateur Radio on the International Space
Station) will auction two very unusual items in its first-ever auction!
Picture yourself as the winning bidder and proud owner of a unique JVC
Kenwood TS-890S signed by astronauts! Or, you could be top bidder on a
special astronaut-signed 6-volume boxed set 2019 ARRL Handbook!
Bidding starts April 8th at 12:00 UTC and ends April 14th at 22:00 UTC.
You could own this one-of-a-kind beautiful Kenwood TS-890S; your ham station
would boast the only Kenwood in the world showcasing astronaut signatures.
Your top bid on the limited edition boxed-set 2019 ARRL Handbook for Radio
Communications would mean your bookshelf includes astronaut signatures among
your book collection.
JVC Kenwood, a proud supporter of ARISS, generously gave a brand new TS-890S
for ARISS to auction. They first offered the radio for sale in the US in
the last half of 2018. Kenwood has been a super supporter of ARISS for
years, and it was the company's idea for this radio, with astronaut
signatures, to be an exclusive that just one ham operator could own! The
company hopes you'll be a bidder who wants to support ARISS.
The limited edition 2019 ARRL Handbook for Radio Communications sold out
fast once ARRL posted their ad. It was the first time that ARRL divided the
Handbook into volumes, which nestle in a hard slipcase. ARRL, an ARISS
sponsor along with AMSAT and NASA, saved back one boxed set to give ARISS
for the fund-raiser auction.
When you bid in this auction you could be the crucial person who helps ARISS
launch its new custom-built higher-power radio system in 2019 with its voice
repeater and improved packet APRS and SSTV capability that thousands of hams
enjoy. The new system will replace the aging, problematic units currently on
the ISS. You may be the winning bidder who helps ARISS continue introducing
ham radio to thousands of students, teachers, parents, and whole
communities-and inspiring students about science, technology, engineering,
math, and radio!
Don't forget; set yourself a reminder: bidding starts April 8th at 12:00 UTC
and ends April 14th at 22:00 UTC.
Be the winning bidder for one or both of these two exclusive offerings and
you'll own a rare article that makes your ham station a classic! More
auction details will soon be posted at www.ariss.org including that winning
bidders will be responsible for shipping costs and for handling any required
customs paperwork. ARISS thanked JVC Kenwood and ARRL for their generous
support.
And if you don't do auctions, please contribute a donation to help ARISS
launch its new radio system into space-look for the Donate button near the
top right corner of the www.ariss.org page. Thank you!
About ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the Center for the Advancement of Science in
space (CASIS) and National Aeronautics and Space Administration (NASA). The
primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or public forms. Before and during these radio contacts,
students, educators, parents, and communities learn about space, space
technologies, and amateur radio. For more information, see www.ariss.org.
