I am hearing reports of RFI from these LED bulbs. Not just HF, but also
VHF.
If you can make any quantitative assessments of such RFI, please let me
know.
And the amazing thing is that at VHF you will never notice it because RFI
is noise power and it is noise power that keeps a squelch CLOSED.
Manuallly open the squelch and sometimes RFI will show full scale on the S
meter yet not open the squelch. And on my radios, when the squelch is
closed, the S meter is inactive and shows 0.

The program can easily detect and fix the TLE preliminary data errors
for working in satellite programs after launching the satellite in orbit
The original version of the program released before launching Fox-1D
works in Windows-7 and higher. Version that works in Windows XP is now
added. The program name for Win-XP changes to TLEdoctor.
Both programs can be downloaded at http://oscar.ok2gz.eu/fox1d.php

Hi folks,
AO73/FUNcube is now in amateur mode for the weekend with the transponder on!
Please see below for all FUNcube mission info
73s Graham G3VZV and the FUNcube team.
++++++++++++++++++++++++++++++++++
FUNcube frequencies and other details
++++++++++++++++++++++++++++++++++
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. Lower
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:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB
Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula…
EO88/Nayif-1/FUNcube-5
EO88 is presently operating in autonomous mode. The transponder is
operational when the satellite is in eclipse, ie the solar panels are NOT
being illuminated.
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.
The transponder frequencies are:
Uplink: 435.045 – 435.015 MHz LSB (inverting)
Downlink: 145.960-145.990 MHz USB
Telemetry Tx: 145.940MHz
All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very
grateful for the assistance given by Innovative Solution In Space Bv, The
Netherlands.

Hi All,
Is anyone else noticing any issues with the JY1-sat dashboard? I
can start it with the sat present and it will instantly lock and track,
next pass it will ignore the signal, kill it and restart it and bam
instant lock.

Hi All,Just to confirm that AO73 is now in continuous education mode with the high power telemetry. Amateur mode may be expected to resume on Thursday morning(UTC)73GrahamG3VZV
Terry,
Thanks for the thoughts.
I "combed" thru the Keps. I did notice that AO-91 had a catalog # of
43015, not 43017. I corrected that. Still, no Joy. AO-92 is OK. AO-85 still
a problem, and AO-91 is still 30 minutes off.
It definitely is something with the Keps. HRD and SatPC32 use different
"element sets".
SatPC32 uses "nasa.txt", HRD uses "nasabare.txt and amateur.txt". I need to
figure out how to get "nasa.all" into HRD. And, one of the 2 element sets,
in HRD, is loading 3 keps entries for AO-91, each with different "catalog
numbers", as noted above.
Also, I have noticed with each "update" (many), the sat track gets slower
loading.
There is an "upcoming" update. I may try and "uninstall" HRD, reinstall
with a "fresh" copy.
Thanks again. Best from the "Florida Keys"

I use HRD Sat., SatPC32 and Amsat Droid.
SatPC32 and Amsat Droid agree on position of FM birds, HRD shows some birds
30 min. earlier than expected. Mainly, AO-91 and AO-85. Anyone else noticed
this tracking error ?
I have "poured" thru ALL HRD's settings, reloaded keps, etc. Nothing seems
to correct this tracking anomaly. Grrrrr.

I’m currently working on some projects that will implement CI-V control of my rig, an Icom IC-910H without the L band module. After a few struggles with the manual being either wrong or missing information I’ve run into what could be a potential problem later. When using command 0x00 to set the frequency, the rig will not switch bands on its own. Whether this makes sense or not is debatable and I have a couple possible workarounds, some uglier than others. I can either read the bands that Main and Sub are on and send my 2m and 70cm frequency to the correct place (elegant) or I can send them both the same frequencies and let the rig sort it out (ugly). Now comes the tricky part. I don’t have the L band module yet but when I do, how am I supposed to get the rig to switch from say L/v to U/v if it doesn’t auto switch bands?
I’m not seeing any commands to handle this situation. Does anyone know if there is an undocumented command or some other type of workaround? I would also be curious what users of SatPC32 experience when they switch between L/v and U/v. Do you manually have to switch bands to regain frequency control or does the IC-910 become smart enough to switch on its own when the module is installed?
Any insight into this would be greatly appreciated.
73,
Mike Diehl
