What I have done is to hook the common port to the antenna that I want and
then the HT up to the side of the duplexer that I want to use. I found it
easier to use the VHF side of the Arrow for this setup.

MFJ sells a duplexer (aka Diplexer). The model number is MFJ-916B.
There are other manufacturers also such as Comet and Diamond, etc.
There was an article not long ago in the Amsat Journal, (or was it QST?),
comparing different models.

The KC8UCH-11 Balloon is down in an area equidistant from Cumberland, MD,
Haggerstown, MD and Winchester VA.
And a few miles west of Martinsburg.
It was launched in Canada and flew overnight.
This was a long distance balloon, I doubt the launch crew will come down
here looking for it.
So, a great DF hunt opportunity. My guess at the landing coordinates are
39N 32.0' and 78W 11.5'
And here is my plot of my prediction:
http://aprs.org/balloon.png
It was coming down going SE and headed right for a ridge line with the
land elevation rising. So I think the prediction should be pretty good
(except for whatever the wind was doing right on the ground as it was
going up and over that ridge?)

Rolf,
I don't know about the magazines, but I saw a review online
comparing the MFJ-916B to a Diamond MX-72:
http://www.w4gso.org/news/comparing-duplexers-mfj-vs-diamond/
The MFJ unit outperformed the Diamond unit.
I have been using the MFJ units for years. They are made in
Taiwan, and are priced at about half the price of the equivalent
Diamond or Comet units. They are rugged, and work well.
73!

US Schools/Groups Move Into Phase 2 of ARISS Selections
June 08, 2018 - The ARISS-US Team (Amateur Radio on the International Space
Station) is pleased to announce schools or organizations submitting
proposals have been selected to advance to the next stage of planning to
host amateur radio contacts from January to June 2019. The contacts will be
with International Space Station (ISS) crew members using the ARISS
equipment on the ISS. A review team of teachers from the ARISS-US Education
Committee selected proposals after the recent proposal window closed. The
groups will go forward to Phase 2, developing an amateur radio equipment
plan to host a scheduled ARISS contact.
ARISS's primary goal is to engage people in science, technology,
engineering, and math (STEM) activities, and involve them in pursuits
related to space exploration, amateur radio, communications, and associated
areas of study and career options. Cord Davidson, KD5J, at Central Magnet
Middle School in Batesville, AR, exclaimed after a recent ARISS contact,
"ARISS shows how amateur radio is the most unique hobby there is, and from
the educator's perspective, what a great way to encourage STEM topics!"
ARISS anticipates that NASA will be able to provide scheduling opportunities
for these US host organizations. The candidates must now complete an
equipment plan that demonstrates their ability to execute the ham radio
contact. Once their equipment plan is approved by the ARISS technical team,
the final selected schools / organizations will be scheduled as their
availability and flexibility match up with the scheduling opportunities.
The schools and organizations are:
Faith Christian Academy
Orlando FL
Hidden Oaks Middle School
Prior Lake MN
Huntington High School
Huntington TX
Moriah Central School
Port Henry NY
NIH-National Center for Advancing Translational Sciences Children's
Inn
Bethesda MD
Park Co. Public Library with Boys & Girls Club of the High Rockies
Fairplay CO
Pembroke Junior Senior High School
Corfu NY
ABOUT ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL) and the National Aeronautics and Space
Administration (NASA) in the United States, and other international space
agencies and international amateur radio organizations around the world. 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 informal education venues. With the help of experienced
amateur radio volunteers from radio clubs and coordination from the ARISS
team, the ISS crew members speak directly with large group audiences in a
variety of public forums such as school assemblies, science centers and
museums, scout camporees, jamborees and space camps, where students,
teachers, parents, and communities learn about space, spac
e technologies and amateur radio.

Well, my prediction was off, but guess what!?? It took off again when the
sun came up and warmed the balloon. That is amazing.
SO it took off from around Martinsburg WV and was over Baltimore at around 3
PM this afternoon above 39,000 feet and headed Southeast at about 60 MPH.
Problem is that it has a terrestrial GPS that shuts down above a certain
altitude to keep legal, and so it wont be transmitting again until it
descends this evening.
But at that speed, my guess it was over the ocean 2 hours later.
Maybe it will survive till Europe? If it can take off rom water like it did
from land this morning.
See the track on APRS.FI

call is KC8UCH-11

Subject: APRS balloon down in WV/MD/VA
The KC8UCH-11 Balloon is down in an area equidistant from Cumberland, MD,
Haggerstown, MD and Winchester VA.
And a few miles west of Martinsburg.
It was launched in Canada and flew overnight.
This was a long distance balloon, I doubt the launch crew will come down
here looking for it.
So, a great DF hunt opportunity. My guess at the landing coordinates are
39N 32.0' and 78W 11.5'
And here is my plot of my prediction:
http://aprs.org/balloon.png
It was coming down going SE and headed right for a ridge line with the land
elevation rising. So I think the prediction should be pretty good (except
for whatever the wind was doing right on the ground as it was going up and
over that ridge?)
