Hi Benno
Thanks for the reply.
As I have said my programming skills are basically zero so with Easy V1.25 ino sketch do you need to add your own code in the sections to monitor voltage and current etc as with the code as supplied all my values displayed are incorrect.
Also where do you get a copy of Easy 2.06 as I have not seen it for download yet?

HI
Has anybody setup an Arduino to work with DATV easy to monitor their PA? In conjunction with the monitoring option in the software.
My software writing skills are zero so would anybody who has this working be able to share their Arduino sketch with me? I can usually work through a sketch to make required changes to work with my setup.

Hello
All of my QO-100 working with both the narrow and wideband transponders are all done with a PC running Windows 11
SDR console, OBS, F1ejp etc all work fine and I have not hand any issues.

Yesterday 7 Jan it was sad to see some many poor operating practices by some trying to use FT8 on QO-100.
With badly over driven transmitters with one station clearly resolvable on three different frequencies.
Many stations where running far too much power which was continually tripping Leila frequently for most of the afternoon and spoiling FT8 for the many operating correctly.
Please monitor your own signal.

Hi Robert
Thanks for the information its exactly what I was looking for.

Hi
Has anybody with an Nokia UMTS PA have any information or a design to obtain any information from the small data socket between the two RF sockets on the front of these PA’s?
I was wondering if power output and PA temp etc. might be available?

Hi Chris
TX with a Lime has been broken for some time now. I was hoping that it may have been fixed in the latest release but this would appear not to be the case.
A work around was to increase the TXdelay in the transmit options
TX options
TX|Tone|Tune
TX Delay
I changed my TX on to around 40ms and this did help and make it more reliable
I have not tried my Lime yet with the latest release as went over to a Pluto but I find the Lime RX better than a Pluto .
Hope this may be of some help.

The most likely problem is a recent windows update as changed the LAV codecs to use the Microsoft own codecs
Download win7DSFilterTweaker_63 this will show you which codecs are being used by various software and it also gives the option to change the codecs in use for given software.
Hope it helps

Hi
I have been given this PA module is anybody able to help identify it?
The pre-driver is a M6S4 the driver amp is a AFT20P060 and the amplifier is a pair of BLF8G22LS-22.
The data sheet for the BLF8G22LS-22 give the frequencies from 2110 MHz to 2170 MHz. Not sure how far it could be moved.
Dose anyone have or used one of these?

Hi Group
I need to order some more MW7IC2725 Mmic devices has anyone got a good recommendations for a reliable supplier?
I have had some good units but also some bad Mmics so its hit and miss.

Hi Thomas
Thanks for the reply
The only ref to LEILA for QO-100
"No uplinks should result in downlink signals that are stronger than these beacons. In the event that such signals are detected, they will be marked by a “LEILA” siren. When they have been marked by “LEILA”, operators should immediately reduce their uplink power (ERP)."

Hi Heiner
As LEILA is implemented how is it working on QO-100 as last night their was some huge signals well above the beacon levels with no sign of LEILA that I could detect.
Is LEILA being implemented the same way as on AO-40 with an audible warning?

Hi
Is LEILA working and implemented as I have not heard when listening to stations well above the level of the beacons?

Hi
What PCB material is being used is it standard FR4 or Rogers?

Hi Markus
Would it be possible to have more details on your PCB?
And if possible to purchase one

Hi Group
I have a 13CM Spectrian amplifier board which I believe is about 60 watts output this is the board with the three LDMOS devices.
The one thing that I can’t find is the connection details. I have tried using Google lot of pictures but no real useful information that I have found.
Could some tell me the following info?
DC Power connections.
Bias connection and bias voltage and what to set the bias current too.
RF drive level.
There is also a small 10 pin header again is there any useful information i.e. fwd /ref power or temp?
Any pointers or links to find the information would be most welcome.
