AMSAT?s next Fox-1 satellite, Fox-1D, is scheduled for launch at 03:58
UTC on January 12, 2018 (10:58pm EST on Thursday, January 11th) from
Satish Dhawan Space Centre in Sriharikota, India. Further information
about the launch and the satellite's early operations, including
preliminary TLEs and FoxTelem settings suggestions, can be found at

Content-Type: text/plain; charset=utf-8; format=flowed
I use Comet CF-4160Ns in the VT ground station.? A while back (June of
2016) I measured the insertion loss and isolation for a single diplexer
with a calibrated Rhode and Schwarz network analyzer 'on the bench' and
the numbers are close to the spec (with a 50 Ohm termination on the
'unused' port for the two port measurements of a three port device).
The claimed numbers are 0.1dB for VHF insertion loss, 0.2dB for UHF
insertion loss, and a blanket '60 dB' for isolation.? In that controlled
measurement situation, for the COM to VHF port path (with a 50
termination on the UHF port) I got 0.048 dB of insertion loss at VHF and
59.695 dB of UHF isolation.? For the COM to UHF port path (50 ohm
termination on the VHF port) I got 0.100 dB of insertion loss at UHF and
73.812 dB of VHF isolation.
So technically the measured performance did better than the claimed
performance on everything except the UHF isolation from the VHF port
which only missed the claimed spec by about .3 dB (assuming I didn't
screw up the cal process).
All of that though, was for a /single/ diplexer.
I'd have to think more about the ganging of two diplexers on either end
of the cable and whether or not you'd actually get the full 'double
isolation'.? Something about that first diplexer and internal coupling
or reflected UHF energy if the there is any mismatch causing UHF energy
(from say a VHF third harmonic) leaking back into the UHF radio.? Maybe
not if you have a good match.....but then coupling at the antennas and
an LNA with gain in the mix.........interesting problem to fully think
through and sort out the details........
On the surface though, if you had two diplexers, one on either side of
the cable, and inserted a UHF signal into the VHF port on one side and
then measured the UHF signal power on the VHF port of the diplexer on
the other side, there would be about 120dB or so of loss in that path (2
times the isolation plus the cable's insertion loss).......just not sure
thats an appropriate test considering that's not quite how the actual
system is installed when antennas and LNAs and radios are all in the mix
and matches aren't all perfect.
Fun stuff to think about though!

Hello!
What TNC are folks using these days to work FalconSat 9600 baud?
I see Symek is no longer in business. Are there any recommendations or will
any 9600 baud TNC suffice?
I'm also wondering if my registered copy of WiSP will run under Windows 7?

Hi all,
Thanks for the link to the article Adrian, that's a very good comparison.
It seems that the differences between the Comet, MFJ and Diamond are minor
and they all meet their specs, with the exception of UHF isolation on the
VHF port, which is in the 55-60 dB range for all units. This is in
agreement with the measurements done by Zach on the Comet. According to the
QST article the Comet's input SWR is a bit higher on the VHF port (1.3:1)
and the Diamond and MFJ's input SWR is a bit higher on the UHF port (1.4:1
and 1.3:1), but nothing too shocking.
I ended up ordering a set of MFJ-916BN's from MFJ directly. Shipping to the
Netherlands is 29 dollars. Not too bad considered the unit price and the
current dollar to euro rate.
Thanks all, I will let you know how they perform when I get them. As stated
before, I will not be using them back to back as in Floyd's situation, but
rather run two feedlines and connect a diplexer to each of them.
73,
Rico

Thanks for all the pre-launch info!
I'm sure it's operator error, but I have not been able to get Orbitron to
recognize those preliminary TLE's.
Some of the digit positions (number of digits in certain fields) look
different from all the other TLE's that are recognized. Thanks in advance
if anyone can let me know how to clean up those pre-launch TLE's to work in
Orbitron.
Thanks!
-Scott, K4KDR
