Hi,
As i'm not following the QO-100 DATV anymore since QO-100 was launched I'm interested in the actual available equipment.
I noticed that the minituner project is end of life due to availability of NB tuners, the UK project get's expensive and difficult due to customs and shipping.
So I was wondering what other options or possible (not using the adhalm pluto)
Are there any NB receivers around these days ?
Thank you Claudio for pointing me to this thread,
This is why i want to use 10mhz , hoping to get a clear answer

Hi adhalm pluto users
I was wondering if someone can point me to a correct explaination on the use of an external reference for the pluto SDR
1) can rev B be used with 10mhz ? (what with other REV's C,D ?)
2) What will be the maximum input level ?
3) Sinus or block ?
4) AC or DC coupled ?
4) What is the exact syntax to switch to 10mhz external reference ?
There is so many confusing information around on the internet
Many thanks
Anyone modiefied this one ?
Thanks for Sharing, but the question was "
Hi,
I was wondering if someone started a project for a DIY tranceiver for QO-100, an uBITX for example modified for QO-100 ?
Looking forward
Thanks i'm familiar with the w6pql or G4HUP (sk) drivers but the questions was:
simple minimum component latching relay driver
So looking forward
Hi Heiner,
First on PTT there is 5V but no Current for the coil, 2nd I have so many latching relays, so happy to see a simple minimum component latching relay driver
anyone ?
Hi everyone
Any idea's on how to make a minimum circuit (important) to switch a single coil latching relay with a voltage on the IF coax during TX (db6nt transverter style)
The voltage on TX is 5V, relays are 12V single coil latching RF relay

Looking forward
Remco , I Mean in terms of Isolation and switching time to prevent damage to the RX parts (ex limiting diodes and fast pin diodes)
Are there any existing designs for a proper "simplex" Transmit/Receive switch between upconverter and downconverter based on PTT voltage on the coax (DB6NT style) ?

Here is my setup
TX Old transverter 2400mhz
Gps locked with 2256mhz lo and
Wi-Fi 5w amplifier
Rx same transverter with build in sym30 mixer, GPS locked 1660.5mhz LO, 27mhz gps locked octagon
All in one simplex use
Hi,
Mant years ago I came accros this GPS chips, unfortunatly never did something with those units
Did anyone tried it ?
it has a 0 to 30mhz GPS locked output
No idea about jitter etc
S59MZ Very elegant solution to use the x2.5 clock multiplier : -)
If you look to the phase noise it is not so elegant anymore
In this moment i am soldering CP2102 as CAT Interface into my prototype case ...
Hi, nice project ,will it be possible to test/evaluate the software with CAT ?
Here is another Websdr, it was already running since the launch of es'hail2
As Es'hail is now on it's final position i made it public
Running a 1.8m dish and an octagon PLL LNB (replaced soon by a 10mhz locked LO)
Enjoy

Hi
Since 1/1/2019 i was monitoring the EB on 11205V
Today i made some new measurements and noticed no change in Azimuth or Elevation for the last 4 days
Further Eshail 1 is on 25.5 east, while Eshail 2 is at 26 deg , so exactly 0.5 deg more to the east
Used RX setup is an Andrew 4.9m Esa Earth station
More reports comming

Happy newyear
Today i checked the ES-hailsat EB beacon on 11205 mhz vertical
And can confirm that it is on 25.5 heading for 26deg
