Safe mode varies from satellite to satellite. In general, safe mode is
designed to protect the satellite and its batteries from harm by turning off
the transponder, most payloads, and any unnecessary power consumption.
The satellite will typically be listening for commands from a control
station and may periodically transmit telemetry that allow the controllers
to determine the status of the satellite systems and diagnose problems.

Ed,
Just curious if you have looked at the DEMI L band TX upconverter. This
was designed for the L band satellite uplink and is a transmit only
converter. The IF can be 28 MHZ, 50MHz or144MHz. What I like about the
idea is there is a verion design to be mounted at the antenna which gets
around the feedline loss issue at 1267 MHz. Still looking at it - as
anyone purchased one?

Hi John
Not familiar with the DEMI converter. I?ll look it up.
The idea of reducing feed line loss has always appealed to me. One of my
AO-13 L-band experiments was a 4? long helix, rear mounted, with a brick
M57762 amplifier on the boom extension behind the cross boom serving as a
counterweight for the helix. Minimum amp-ant feedline loss. The transverter
was in the shack. I used the transverter to amplifier feedline (~40? rg213)
as an attenuator to reduce the transverter?s power output (too strong fir
the brick) to the correct level for the brick. (Worked properly, but the 10W
output was really too weak for the high orbit sats). Man, that was fun stuff.
I have toyed with a similar concept for a fixed station now, with a much
smaller antenna. The present transverter is too big and clunky to mount in a
box with the amp on the tower, but the W1GHZ transverter can be quite small.
Not a real high priority but interesting nonetheless.

I am still having problems with the 9700 on Mode J.? Has anyone yet used the
MFJ-916BMN duplexer on their system?? I like the fact that it is designed
for outdoor use and can be mounted to the mast.? I have a comet CF-416, but
would have to build a waterproof box for it if used and left on the

HuskySat-1 Designated HuskySat-OSCAR 107 (HO-107)
On November 2, 2019, the HuskySat-1 cubesat launched on the Cygnus NG-
12 mission from Wallops Island, Virginia, USA. The satellite was con-
structed by the Husky Satellite Lab at the University of Washington,
and utilizes an AMSAT-constructed radio system for primary communica-
tions. Deployed from the Cygnus vehicle on January 31, 2020 after de-
parting the ISS, HuskySat-1 began a 3-month educational mission. Upon
completion of that mission, the satellite began operation of a V/u
linear transponder in amateur service.
At the request of the Husky Satellite Lab and AMSAT teams, AMSAT here-
by designates HuskySat-1 as HuskySat-OSCAR 107 (HO-107). We congratu-
late the Husky Satellite Lab, thank them for their contribution to the
amateur satellite community, and wish them continued success on this
and future projects.

I have used a MFJ-916B in my portable setup and it was the biggest
improvement I have made to my setup. I have since moved to a Mini-Circuits
BLP-200+ as I use 2 radios verse a single full duplex radio.

Well what can I say other than last night it was transmitting about once
every 2 mins and the mode said "safe", this morning I see the mode is
back to "health"
Maybe I was dreaming.

Just to mention on the BLP-200+, you can't transmit through it as it has a
0.5 watt maximum RF power. It is designed for a receive-only lines.
