Hello
Just be a bit careful about what programs you use to feed the internet with
space data.
UI-VIEW for example dumps packets that are identical and heard less than two
minutes out
We are essentially loosing space packets.
I am going to run a TNC and use a raspberry pi and a direct link.
I just saw two strong packets from the ISS and only one made it
Does the APRS-IS crush dup packets in a short time ?

SatPC32 will also control the SDRPlay with SDRUno the same way.
My linear satellite setup is a FT-817nd, a SDRPlay and a laptop running
SDRUno and SatPC32. The radio communicates with SatPC32 via a CAT Bluetooth
dongle. Make sure to add filters on each feedline to get rid of desense, if
using an Arrow antenna.

We have already told you several times to stop using UI-view since it is
out of date and it's author died more than a decade ago.

Hello Paul,
Regarding software to control doppler on SDR:
For sats, I run HDSDR V2.76 using a generic SDR with RTL2832 Chip.
Running http://amsat.org.ar/pass.exe handles nicely SDR Freqs.
Seamlessly clicking any satellite, its Freqs+Dopplers are set on SDR.

HA! Never thought of using them together. Got it working with my
generic RTL Dongle; so easy!
Thanks!

Andrew,
Most every post I see you make in this BB is either rude, full of
complaints, or similar. Perhaps if you worded your responses in a more
strategic, kinder way, you would receive kinder, more helpful answers or
responses in return.
Just my 2 cents.
Cheers,
Tucker

Telling HDSDR to emulate (rtl dongle) a TS-2000 allows any program to
control it. PSTrotator, Satpc32, etc.
I use VSPmanager (free for hams) to handle the virtual serial ports necessary.
Flex 5000a can use the same work around. Not all programs will control
a Flex. Telling PowerSDR to emulate a TS-2000 allows the Doppler
correction to be set, along with basic xcvr control.
Best SDR? Nooelec. The one in the aluminum box works best related to
cost. Only downfall of the cheapie RTL's is that they drift with
temperature. The aluminum box handles EMI/temperature swings well
without a big investment.
Funcube dongles are pricy due to VAT. Nice, but not $200 worth of
improvement, compared to the Nooelec.
Ettus B210 is a great radio. A fair amount of building is necessary to
complete the project. Amp chips, power supplies, relays and the like.
Doable, but assembly requires a fair amount of time, materials and
energy.
All of them (except the Flex 5000a) are somewhat limited in the AGC
department.
