Hi Tony,
The chuff chuff noises are from space...they are a sort of beacon carried on
every Orbcomm satellite. They are 125msec long pulses of 57.6kb data and
have a bandwidth of around 50kHz. They are quite distinctive when you only
hear one at a time but sometimes one can hear two or more
Hi,
I have a spectrogram and a recording of that chuff chuff on

Is it the same you guys heard?

Well, we're hearing something like that. Though we hear this a lot, we
also wonder whether we''re seeing an envelope during the Prospero pass
times.

Hi Jan
Yes - that's exactly the sound I have been receiving. I tried putting in the
TLE for an Orbcomm sat when Graham told me about them, and the doppler
correction seemed to match.

Hello all.It is time again for the HVSGN. I am sorry for the technical problems
we had during the last net. Please join us and share your satellite experience
with the Net. Hope to hear you there 73 Gary WA2AQH/Tom KC2DTQ

Morning all,
I was curious what the standard was for Logbook of the World (LoTW)
reporting. Which band do you log your QSO with, Uplink or Downlink?
I've been seeing mix results coming back via LoTW, where HRD Log defaults to
using the downlink frequency although I've had some QSO's report back
Nothing heard from Prospero here in Leicester, that pass just finished (at
14:57Z)
Just the Orbcomm swooshes.

We're hearing these 'chuff-chuff swooshes' too, though at times when our
software is not showing Orbcomm over our horizon. Our TLEs may be
slightly out-of-date, though I think it would be a marginal thing. Can
it be definitely confirmed that these noises are Orbcomm?

LoTW satellite convention is the uplink band.
LoTW works well for satellite contacts and VUCC. I'm currently seeing about
20% confirmations.

The standard should be what is shown in N5JB's helpful PDF
for satellite operators using LoTW. It is available from the
ARRL web site:
Thanks for the clarification! Now I need to go correct my logbook.

Hi Roger
Once Graham told me the noise was Orbcomm this morning, I added the TLEs for
their satellites
(http://www.orbcomm.com/Collateral/Documents/English-US/o11292.tle)
to my SDR Radio software satellite definitions. Here's a pass I recorded from
one of them this morning, and you can see
Besides the occasional MDS dishes, is there a source now of larger
commercial 2.4 GHz wire or mesh dishes?

I believe that would require a (ra)dome to make it aerodynamically
acceptable. I would also believe it would require azimuth and elevation
controls as well since the vehicle and object will be moving.

Armando, that's correct, E1P and RAX-2 are now on different frequencies.
Thanks to the IARU for helping us coordinate!

Thanks for bringing this to my attention. It looks like the telemetry server
had a slight hiccup.
Telemetry was still being accepted and was saved, but the web pages were not
being updated.
I gave the telemetry server a gentle nudge. It has started updating the web
pages again.
