I am not sure if auction listings are allowed on amsat-bb.



I noticed there is a Yaesu G-5500 AZ/EL rotator controller and an Icom
IC-970A on the Schulman site for the current auction.



You can see them by going to:

http://bid.schulmanauction.com/



I have purchased things from them before without issues.

I had a decent pass just now,

Hi Clint !

Congratulations for your next 89th Sat session at Palm Springs, will
sure spread satellite passion to new breed, we appreciate that.

To possibly assist your  "Work Ham Satellites With Your HT"
presentation, perhaps you can show real time availability of ham
satellites.

Thru http://lu7abf.com.ar/pass.htm , that works on any portable device
(smartphones/tablets) as well as any Op. System in Mac's or PC's.

Also useful as a graphical education tool to simplify and ease
understanding of Ham's satellite tracking that could operate offline
or online.

Wishing good success at Palm Spring HamFest, with thanks for your your
long standing compromise with Sat amateur community.

73, lu7abf, Pedro Converso

I'm in the Chicago suburbs. The most recent pass was nearly overhead for me.
I copied the same as you described. There were signals in my waterfall but
none decoding. The downlink signal sounded much weaker than usual (by ear).
The findu.com page logged only one station getting gated and a few telemetry
packets.

I was on the 145.825 packet digipeater aide. With Fl-digi I think you were
trying the PSK side. The next pass at around 11:45 AM central time was about
20 degrees elevation and I could barely copy the 145.825 downlink on that
pass. Also, no USA stations or telemetry were gated to the findu.com site.

Joe,

I was not on that pass.

  Most of the time, you will see the telemetry very strong down at
310Hz.  You should see your own signal where ever you put it. (I use
1600Hz)  You should also see the non Doppler corrected beacons. These
skew across the waterfall.  Won't waste time trying to copy them.

Now for FlDigi...   The maximum acquisition range is 500 Hz.  If the
signal is not within the "Red" bar limit above the waterfall, the
program will not look for it. Also look in the configuration for multi
option being selected.

CONFIG/OPERATOR/MODEM/PSK/MULTI

As a frequent user of NO-84_PSK31, I recommend DigiPAN or WinPSKse. They
each have their advantages.  DigiPAN copies many signals with limited
AFC.  WinPSKse copies only two signals with 3,000Hz of AFC.   Your choice.

Hi folks,

  I have just changed the sat into amateur (continuous transponder) mode.
Plan is to switch back to auto mode on Sunday 15 Jan 2017 pm UTC as usual.

Apologies for the delay in switching this weekend which was due to an inter
command station communications error.

Pls see below for FUNcube transponder info

Have FUN with the transponder.


73s Jim G3WGM and the FUNcube team.

AO-73 FUNcube-1

The transponder is normally operational only when the satellite is in
eclipse, ie the solar panels are NOT being illuminated. During weekends
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.



When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power. During holidays,
eg Christmas, New Year, Easter, etc, the transponder maybe activated for
extended periods. Watch AMSAT-BB for announcements which are usually made on
Friday evenings (UTC)



The nominal transponder frequencies are:
Uplink:   435.150 - 435.130 MHz LSB (Inverting)

Downlink:   145.950 - 145.970 MHz USB

Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15kHz higher depending on on-board temps. Low
temperatures give higher freqs!)





FUNcube-2 aka FUNcube on UKube

The FUNcube-2 sub-system continues to operate autonomously and, almost
continuously, in amateur mode. The transponder is operational and the
telemetry downlink is functioning with

about 70mW output. The FUNcube-1 Dashboard does not correctly display the
telemetry but it

does correctly decode the data and uploads it to the FUNcube Data Warehouse
from where

it can be examined. Most of the real time data channels are operational and
these include

battery voltages, temperatures and ADCS data coming via the main On Board
Computer (OBC).



The transponder is interrupted for a few seconds every 2 minutes when the
other transmitter

sends its CW beacon and, occasionally, for a few seconds when the main OBC
reboots (approx seven times each orbit).



The nominal transponder frequencies are:

Uplink:   435.080 - 435.060 MHz LSB (Inverting)

Downlink:   145.930 - 145.950 MHz USB

Telemetry Tx: 145.915 MHz BPSK

(The passband may be up to 10kHz higher depending on on-board temps. Low
temperatures give higher freqs!)





EO79 FUNcube-3

Due to power budget constraints the transponder cannot be operational 24/7
and an orbit specific schedule has been developed. The transponder will
commence operation 27 minutes after the spacecraft enters sunlight and will
stay on for a period of 25 minutes. This schedule may be modified in future
months as a result of experience.



The nominal transponder frequencies are:

Hi folks,

  I have just changed the sat into amateur (continuous transponder) mode.
Plan is to switch back to auto mode on Sunday 15 Jan 2017 pm UTC as usual.

Apologies for the delay in switching this weekend which was due to an inter
command station communications error.

Pls see below for FUNcube transponder info

Have FUN with the transponder.

All,

If the current trend continues, BY70-1 may be expected to decay and
burn up in the atmosphere by mid-February.

The apogee of the satellite has decreased from initially 520 km to now
426 km and the perigee has decreased from initially 216 km to now
208 km.

73,
Nico PA0DLO

Would it be a good idea to mention what you use for uplink doppler
correction?
I assume Andys K0SM's DopplerPSK?
