Description

QO-100 Satellite 739/144 MHz RECEIVING Converter Assembled in Box
To note please:
QO-100 (Es’hail-2) satellite is NOT covering North America, USA and Canada ! See its covering map below.
This sale includes the Assembled in Box
QO-100 Satellite 739/144 MHz Receiving Converter and Power Cord.
This receiving converter was designed and described by
David Bowman G0MRF
in his article
“G0MRF UHF-VHF Receive Converter for use with a satellite LNB”
in open source on AMSAT-UK web site. Do search in Google and you find this article.
This converter was designed to use it to receive the signals from modern
QO-100
or
Es’hail-2
amateur radio satellite. This satellite was put on the
geostationary orbit
at position
25.9°E
.
See its covering map on the pic up this listing.
Its uplink frequency is on
2.4 GHz
band and downlink frequency is on the
10 GHz
band. So the low cost
Satellite TV dish (60cm min.)
with
10 GHz (LO 9.75 GHz) modified LNB
can be used to receive its signals. Modification of LNB represents a
replacing of 25.000 MHz crystal in LO of LNB to the high stability TCXO of 25.000 MHz.
Not all LNB will work there. It needs the modern LNB with PLL synthesizer in its LO.
You can buy 10 GHZ MODIFIED LNB
here
To note please:
Ideally using this converter along with the
low cost Dongle SDR
tuned on
739.550 to 739.800 MHz
or
2 meters band receiver
tuned in a range of
144.550 – 144.800 MHz
with LNB in
Vertical Polarisation
you can receive the signals of
narrow band transponder
of this satellite.
Because of all LNB have some offset of its LO to seek the signals of satellite in a more wide band.
Inside the box is placed the RX Converter PCB board you can see on this pic.
I can not help you about installation and pointing the dish. This all things you should know and do by yourself.
More information about this satellite, its transponder band-plan and antenna beam coverage you can find in the Internet.
Also on YouTube you find a lot of videos showing how people works with this satellite and their equipment. Just do a search by “QO-100” words on YouTube.
BE CAREFUL !
Although this converter has a protection chain applying RF power to its output might damage it. So if you use this converter with VHF radio do not push the transmit button of your VHF radio !
