Hi Tim, a problem with that configuration: you need access to the pins
Ground and DTR (pins 5 and 4) of the serial port to steer the buffer
interface. To steer your Yaesu radio via the Radio 2 COM port you will
use a USB-to-Serial converter + a Yaesu CAT cable, e.g. the CT-62. This
cable comes with a DB-9 connector on one side that connects to the
converter and a mini DIN plug on the other side, that connects to the
radio. So, you don't have direct access to the lines Ground and DTR.
What you could do: Solder a short cable with a female DB-9 connector on
one side and a male one on the other side. Connect the female side to
the USB-to-Serial converter and the male side to the DB-9 connetotr of
the CT-62. With that cable you can then easily lead out 2 extra wires
to the Ground and DTR pins to control the interface.

Hi Erich,
Thank you for this. Yes, that was going to be the general plan. I am
looking through my junk box to see what parts I have and if I have the
needed hardware. I was not aware that a USB to Serial converter derived the
extra pins (per your earlier post) like DTR and RTS from the USB inputs of
Vcc, GND, D+ and D- and made them functional. I assumed it only provided
TXD and RXD at RS-232 levels. So, if it makes those pins available and
functional, that should do it. I just need to construct and test which
might take a couple of days for me to accomplish. Thanks again.

You don't need a PC with a phyical COM port. The voltage at the DTR pin of
my USB-to-Serial converter (which generates the Radio 2 COM port) changes
between +6 (high) and -6 V (low), when the user switches between v/u and
u/v satellites. The corresponding option in menu 'Options' must be checked,
of course.
If the DTR pin is low, the buffer interface locks and the relay remains
open. If the pin is 'high', the interface is routed and the relay closes. I
do not have a transfer relay, but have successfully tested the function with
a 12 volt coax relay.

Yes, I can also confirm that you get functional DTR & RTS from a
USB-to-Serial cable. I use one for connecting to my PTT relay as
illustrated here:

AMSAT Field Day on the Satellites
The weekend of June 22-23, 2019 is Field Day! Each year the Ameri-
can Radio Relay League (ARRL) sponsors Field Day. The Radio Amateur
Satellite Corporation (AMSAT) promotes our own version of Field Day
focused on operation via the amateur satellites, held concurrently
with the ARRL event.
The AMSAT Field Day 2019 event is open to all Amateur Radio opera-
tors. Amateurs are to use the exchange as specified in ARRL rules
for Field Day. The AMSAT competition is to encourage the use of all
amateur satellites, both analog and digital.
The congestion on FM LEO satellites is always so intense that we must
continue to limit their use to one-QSO-per-FM-satellite. This includes
the International Space Station. You will be allowed one QSO if the
ISS is operating Voice.

Lightsail-2 Scheduled for Launch June 22 - Beacon on 437.025 MHz
LightSail is a citizen-funded project from The Planetary Society.
This cubesat will be propelled solely by sunlight, to Earth orbit.
LightSail 2 is scheduled to launch aboard a SpaceX Falcon Heavy on
June 22, 2019, and we will attempt the first, controlled solar sail
flight in Earth orbit.
LightSail 2 will ride to space aboard the Department of Defense
Space Test Program-2 (STP-2) mission which will send 24 spacecraft
to 3 different orbits. LightSail 2 itself will be enclosed within
Prox-1, a Georgia Tech-designed spacecraft originally built to demon-
strate close-encounter operations with other spacecraft. Prox-1 will
deploy LightSail 2 seven days after launch.
After a few days of health and status checks, LightSail 2's four
dual-sided solar panels will swing open. Roughly a day later, four
metallic booms will unfurl four triangular Mylar sails from storage.
The sails, which have a combined area of 32 square meters [344 square
feet], will turn towards the sun for half of each orbit, giving the
spacecraft a tiny push no stronger than the weight of a paperclip.
For about a month after sail deployment, this continual thrust should
raise LightSail 2's orbit by a measurable amount.
LightSail 2 will fly in a 24-degree inclination, 720 km, circular
orbit. At latitudes of 42 degrees north it will reach a maximum
elevation of 10 degrees above the horizon.
Lightsail-2 has been issued an experimental radio license WM9XPA and
transmit on 437.025 MHz. A morse beacon will transmit the callsign
every 45 seconds. A packet beacon will transmit AX.25, FSK 9K6 bps
data.
Beacon information is available at:
http://tinyurl.com/ANS-153-Lightsail-Morse-Beacon

AMSAT-EA FossaSat-1 Receives IARU Coordination
The IARU reported that AMSAT-EA FossaSat-1 satellite has received a
downlink coordination to operate on 436.700 MHz with LoRa 125kHz,
Chirp Spread Spectrum Modulation, 180 bps, 100mW; and, FSK RTTY 45
baud ITA2, 100mW 183hz Shift.
The planned mission objectives for the 5x5x5cm 250gram satellite are:
+ General development of miniaturized and inexpensive satellite
? systems for space applications using off the shelf components.
+ Testing a new solar panel mechanism, making this satellite the
? smallest to have deployable solar arrays. These solar arrays will
? additionally increase the radar reflectivity significantly to
? that of a standard cubesat.
+ The promotion & involvement of students in aerospace development
? on an international level, giving them the opportunity to test
? their hardware and software experiments on the satellite. AMSAT-EA
? will be hosting STEM workshops & competitions for secondary stu-
? dents to participate in, a full section of the satellite is dedi-
? cated to these experiments for educational research.
+ The main mission of the satellite is the testing of a new experi-
? mental RF chirp modulation called LoRa, this new modulation hugely
? increases the link budget, reduces the power consumed and reduces
? the cost of receivers.
Students & Amateurs will be able to receive telemetry from the satel-
lite with inexpensive hardware, expanding & promoting the amateur
satellite community among youth.
Uplink challenges will also be carried out with rewards for amateurs.
AMSAT-EA will provide decoding software for SDR use in order to allow
anyone to decode LoRa using common existing hardware & host software
for users to submit telemetry data, making all data public and reward-
ing users with certificates & awards.

ARISS SSTV Planned Over Russia for Moscow Aviation Institute
A Russian MAI-SSTV event is planned for Wednesday, June 5 from
12:00-16:00 UTC and June 6 from 11:30-15:30 UTC.? Transmissions are
expected to be at 145.800 MHz in SSTV mode PD120. Based on the times
received, SSTV signals are not expected over N. America.
This event uses a computer in the ISS Russian Segment, which stores
images that are then transmitted to Earth using the ARISS Amateur
Radio station located in the Service Module which employs the
Kenwood TM-D710E transceiver.
Amateur radio operators and other radio enthusiasts are invited to
post the images they receive at
http://www.spaceflightsoftware.com/ARISS_SSTV/index.php
Please note that the event is dependent on other activities,
schedules and crew responsibilities on the ISS and is subject to
change at any time.
Online WebSDR receivers can be used to receive signals from the
International Space Station at SUWS WebSDR located Farnham near
London http://farnham-sdr.com/ and R4UAB WebSDR located European
Russia http://websdr.r4uab.ru/.

Send Your Name (and callsign) to Mars
NASA Press Release May 21, 2019
NASA is giving the public an opportunity to send their names ? etched
on microchips ? to the Red Planet with NASA's Mars 2020 rover, which
represents the initial leg of humanity?s first round trip to another
planet. The rover is scheduled to launch as early as July 2020, with
the spacecraft expected to touch down on Mars in February 2021.
The opportunity to send your name to Mars comes with a souvenir board-
ing pass and "frequent flyer" points. From now until Sept. 30, you can
add your name to the list and obtain a souvenir boarding pass to Mars
here: https://go.nasa.gov/Mars2020Pass
The Microdevices Laboratory at NASA's Jet Propulsion Laboratory (JPL)
in Pasadena, California, will use an electron beam to etch the submit-
ted names onto a silicon chip with lines of text smaller than one-
thousandth the width of a human hair (75 nanometers). At that size,
more than a million names can be inscribed on a single dime-size
microchip. The chip (or chips) will ride on the rover under a glass
cover.

RS-10 Downlink Provides Unique Troubleshooting Solution
Terry Osborne, ZL2BAC, recalls a troubleshooting solution utilizing
the downlink from the RS-10 satellite as he was resolving an HF noise
problem in the radio system of New Zealand's Maritime Radio Network.
(http://tinyurl.com/ANS-153-NZ-Maritime-Radio)
The New Zealand network consists of a chain of VHF base stations, an
HF Transmitter site and an HF Receiving site. These are all linked
back to an Operations Centre in Lower Hutt (near Wellington).
During commissioning, Terry was visiting the Operations Centre where
the operators mentioned that the HF receivers were very noisy. This
didn't sound right since the receiving site had been chosen because
it was in a remote area well away from any man made noise.
Terry said, "To check how well the receivers were working I gave the
operators the frequency and a week of pass times for RS-10. This was
on a Friday. On Saturday I turned on my receiver at home on RS-10.
My receiver was a TenTec Argonaut 505 with DGFet preamp and a half
wave dipole at about 10 feet. RS-10's downlink boomed in at about 5x7.
The Maritime operators heard nothing on their receivers. I fed the
audio down the phone line to convince them it was working."
The four HF receivers are fed from a Multicoupler that has a "Low
Noise" amplifier feeding a splitter. On the following Monday, the
technicians from the maintenance base visited the site and at AOS
of RS-10, turned off the power supply to the multicoupler. The Oper-
ations Centre reported down went the HF noise and up came the signal
from RS-10.
Terry reported on the solution, "There were many options for the 'Low
Noise' amplifier in the multicoupler ranging from a 2dB noise figure
10 dB gain version up to a 30dB gain 15dB noise figure version. Upon
removing the lid from the multicoupler it revealed that the 30dB gain
15dB noise figure version had been supplied rather than the 2dB noise
figure 10dB gainversion specified. It turned out that the manufacturers
of the Multicoupler hadn't actually made one with a 2dB NF/10dB Gain
amp before and had just supplied their standard version. Putting in
the right amplifier solved the problem."
In closing, Terry wrote, "Satellite operators who have worked with
preamps will recognise this problem."
