I designed the DUV telemetry system on Fox-1, with an important
suggestion (use 8b10b coding for spectral shaping) from Tony, AA2TX.
It's important to remember the severe design compromises imposed by the
requirement that the satellite itself be an analog FM repeater,
confining the telemetry to modulating frequencies below 300 Hz.
These design compromises would have been unnecessary with a fully
digital communications payload, like those on every non-amateur
satellite launched in at least the past decade or two. I've made it
clear that this is my last telemetry design for an analog spacecraft.
It's past time for AMSAT to move into the all-digital era.

Good evening,
On the 0153Z pass of AO-73, I worked Chris, 9Y4D, in Trinidad & Tobago
(FK90gg). Chris is relatively new to the satellites and has been heard on
FO-29, XW-2F, and AO-73. I've worked him on both XW-2F and AO-73. He uses
LoTW.
9Y has been relatively uncommon on satellite, so keep an eye out for him if
you need it!

Phil, I don't dispute your expertise in this opinion -- you're right when
you say:
> It's past time for AMSAT to move into the all-digital era.
But, the appeal of using a pair of HTs or other simple radios with an Arrow
sure is strong -- especially for truly neophyte operators.
What would replace this entry level equipment? A laptop and an Arduino and a
radio?
Really curious what you think; I expect you have a very learned opinion.

Dear Phil,
I'm wondering if it would be reasonable for future satellites to use an
SDR transmitter, to allow to use an analog FM downlink and digital
telemetry on two different frequencies (spaced about 20KHz apart or so).
As others have said, analog FM is quite desirable because it allows for
a very simple groundstation. Also, the current state of amateur digital
voice is not so stable with all these competing standards that have
closed implementations or use patented codecs.

Dani M0HXM/EA4GPZ.

Hi all!
Is there any website around that keeps track of each satellite
confirmed QRB records?
I'm looking into how far anyone worked on each sat.

There has been things like that in the past, but I don't know about any
currently existing. We could certainly create one on the AMSAT website!
This is what I can find:
AO-40 - 18,263km (I8CVS in JN70es and ZL1AOX in RF72mv)
AO-7 - 7,947.381km (KG5CCI in EM24uq01mu and EA5TT in IM99sl48cx)
FO-29 - 7,599.959km (KG5CCI in EM34st11tl and F4CQA in JN17ea22ot)
If anyone would like to claim records on any other satellite, please post
your claim. I will create a page with this information.

This page is now live on the AMSAT website:

There's a link to it at the bottom of the Communications Satellites page.
Again, please claim records for other satellites if you think you may hold

Hi,
Thanks!
I'm compiling a list of the maximum possible QRBs for two targets
standing at sea level, and the max known sat altitude that I can find.
If you'd like that I can send it to you later.

Thanks, Pedro. I've seen calculations for those distances before, but they

Hi,
I'm using formulas to determine the distance to the horizon from the
satellite, then the distance across the (curved) surface between two
opposite locations.
Again, it's meant for sea level. AO-7 solves with 7,858.478 Km which
is below the record of 7,947.381 Km. This is because the higher from
the sea level you are, the farther you are in the sat horizon.
I'll send you that list later today.

This post is specific to Icom IC-9100 users.
There have been some ongoing discussions about whether or not to use
Narrow FM for uplink or downlink on AO-85. My observation is that
Narrow FM (Filter 2) for the downlink works best. For the uplink, I
leave Filter 1 enabled.
This is easy to do in your DOPPLER.SQF:
AO-85,145980,435175,FMN,FM,NOR,0,0,Transponder
The first FMN will set Filter 2 for your downlink
The second FM will set Filter 1 for your uplink.
I've also noticed Filter 3 makes LilacSat-2 sound best but I am
unaware of a command via SatPC32 to select that filter automatically.

Hi Pedro,
I found this 2 Qso by AO-13 when I was using IW1BMJ callsign:
IW1BMJ in JN45fc and VK8KTC in PH86ed (Jun 7, 1990 12:19 UTC)
IW1BMJ in JN45fc and VK4ASB in QG62mp ( Nov18, 1990 23:04 UTC)
