Hello,
Pluto is near the antenna on the balcony. I have two ways to connect the device to a PC:
20m Ethernet with adapters or 20m USB 2.0 Active Extension (e.g. https://www.lindy.co.uk/cables…2-0-active-extension-p510). What is the difference ? In either case I need a line.
Is it also possible to connect the Pluto via WLAN/WiFi. Any experience ?
Thanks

Hi Stephen,
you can find some radiation pattern of flat antennas here: http://www.antennenfabrik.de/w…ent/uploads/RA_gesamt.pdf

DH2VA you are not paranoid ....
you do not necessarily require a compass. With https://www.dishpointer.com/ you can find some prominent points.
QO-100 is 26E ARABSAT 5B...... -
Hi Oliver,
Turn the antenna approximately in the direction of the satellite, transmit on a known uplink frequency, then controll the associated downlink frequency with WebSDR (http://websdr.is0grb.it:8901/ or https://eshail.batc.org.uk/nb/).
Turn the antenna to find your signal. If signal is strongest, you have the correct direction. OK ?

Hi,
@Robert
no possibility to meassure SWR, data sheet says SWR <=1.5
@Mike
yes, antenna is only for uplink QO-100. Data sheet says max. power input 100W. Complete data sheet of antennahere: http://www.sunparl.com/en/prod…getclassid=18&detailid=91
I found a 1m long low attenuation 50 Ohm coaxial cable assembled with N plug, SMA plug. Loss about 0.41dB. Coax cable is CLF240. Abt. 20€. I found adapter N->SMA for abt. 6€ (noname) and 45€ (Rosenberger).

Hallo Christoph,
meinst du die Helix13-40 (best.Nr. 18029) mit 1,25m Länge ??

Hi David,
today I got it.
Soldering the TCXO is a big challenge. Advice you can get from Lucien: https://www.f1te.org/index.php/realisations/sdr/adalm-plutoI have meassured the stability and deviation (if TX) of the TXCO on his frequency (40MHz):
Maybe there is an improvement by drilling some holes into the plastic housing

Hello David,
I think, it is the same.
In Germany Mouser has free shipping for orders over 50€. Otherwise minimum shipping cost 20€.

Hi,
not sure if this thread is in the right sub-forum.
You can buy the TCXO in ebay and save delivery costs
