The last couple of days EO-88's telemetry has been uplinking to FO-29 in
passes over the US.

I recorded some data being sent via FO-29 today approximately 16:21 UTC.
Very strong signal.
If you skip to about 6 minutes, 44 seconds into this recording you will hear
it:
https://clyp.it/m4lalgl5?token=2c0365f763bcb95a6e42a5d7fe003d6b
Afterwards you can listen to a pileup of stations working UT1FG/MM.
I can email you the MP3 if you'd like.

Perhaps termination would help on the diplexer ... so far, I've kept it
simple and just unplugged the unused antenna on the Arrow. It 'seems' to
work OK when using the FT-1634.

I would like to get at least one and up to five contacts on the pass. I am
doing the RaDAR challenge from St Andrews State Park at EM70. My first Sat
contact will count as a bonus. Eddie ZS6BNE came up with the RaDAR ideal
and he loves Sats. In Radar, you make five contacts and move. However, I
don't want to interfere with any special operation already scheduled. You
can find info on RaDAR on my web site N4KGL.info Just scroll down.
Thanks,

Hello everyone,
I also heard the pileup and this data and also asking myself what it was...
Thanks Clayton for record of my audio, nice to see that you have better
return than me :) Still waiting for a little more power out and V/UHF
preamps.

Hello everyone,
I take advantage of this question to ask if you know to increase the limit
of 10 birds on satPC32 to adjust of number of active sats.

Clayton,
Thanks for sharing that recording. It was fun listening to the Yuri-pile!!!
The data signal on your recording did not sound like the signal that
would?force me to QSY on several FO-29 passes while I was roving in
the?South the last couple of months. Your recorded signal had distinct
frames?with what sounded like syncing at the beginning and end. The signal
that?QRMed me was continuous once it started and I couldn't make good?QSOs
through it.

All,
ITF-2 (YUI-2) entered normal operation phase on Mar 25th JST.
Telemetry information and messages will be transmitted in this phase for
the achievement of main mission.
The details of the AWARD and SWL cards are as below,
AWARD?
With reference to the message on Jan 15th UTC,
the First 100 Reports from overseas stations are qualified for this award.
Only ten overseas stations sent report so far. Still enough award can be
issued.
Additionally, a souvenir, a sticky screen cleaner, will be given with this
award.
The design motif is the small antenna of ITF-2.
Design of the cleaner:
https://twitter.com/yui_tsukuba/status/841096655046758400
SWL cards:
Five designs are prepared. The stations which report more than five times
can receive all designs.
Also, the specially designed card will be presented to the stations which
received a signal from the small antenna,
because the reports are valuable to demonstrate the antenna in space. So
far, two stations succeeded in the reception.
Designs of SWL cards:
https://twitter.com/yui_tsukuba/status/846219342190555136
Futher special events are planned for the promotion of receptions by more
stations.
This will be announced later.
There were some reception reports by very simple equipments,
for example, Dipole or 5/8 wave length whip with USB tuner dongle (RTL2832).
The examples are as follows,
Ex1:https://twitter.com/dspic/status/842000948834717696
Ex2:https://twitter.com/dspic/status/826823146955120640
Reception reports can be submitted at:

I actually dug up a Comet CF-4160J Diplexer (both Comet and Diamond call
them "Duplexers") and swept its response with my Spectrum Analyzer, using
the Low-Frequency and Common Port. I was also curious to find out if it
mattered if the High-Frequency Port was terminated or not.
The bottom line is that this particular Diplexer would reduce the 2-meter
3rd harmonic by 55 dB, and had an insertion loss of 0.12 dB. And I
confirmed that there was a small reduction performance if the
High-Frequency Port was not terminated.
I would expect the performance of Diamond models would be similar and I
will test one when I find one.
The actual report can be found here: http://wb4son.com/wpblog/?p=2828 (if

Hi!
Another option for diplexers as bandpass filters would be the MFJ
diplexers. I use an MFJ-916B diplexer for my satellite station,
and I saw a test comparing this with a Diamond MX-72 diplexer
that was done a little over a year ago:
http://www.w4gso.org/news/comparing-duplexers-mfj-vs-diamond/
Summary: the MFJ diplexer outperformed the Diamond unit. Also, the MFJ
diplexer costs about half of what you normally see for the equivalent
Diamond or Comet units. And the MFJ-916B is made in Taiwan, not
Mississippi.
73!
