a friend of mine bought Adalm-Pluto, and a kit for TXCO mod. But is this mod really necessary ?
Or is a waste of time ?
May be that the new version has a more stable TXCO, and the mod is useless.
Okay, I know that rev C has a special port for the esternal 40 MHz Clk, from GPSDO.
But my friend, for the moment, don't want use this solution.
Any suggestion, hints ?
Thank you for reading.

At 10Κ € is too expensive…
Someone tells about that quotation, is a "undefinited price". We are waiting for the official exit on the market to evaluate the real price. Estimation of the price are : from 3000 to 4000 UDS or EUROS. The 10 GHz Unit could cost 1500-2000 USD or EUR.
9999 USD is crazy, but if someone reached madness...
hello, please tell me how to download the program, HF power meter, it does not work using the links.
I have been tested the program one year ago. It had too much issues to work properly, due to this reason I deleted the program. You can send an email to the supplier, in my case they answered to me with the link (in chinese ).
I did it already directly to him. But he said that he cannot, at least now.
If the source code would be open, no problem ...
What is only needed is not "Dual Tioune", but a Minitiouner SW compiled for using the other tuner of the NIM.
I agree with you.
Unfortunately, this solution isn't good for Minitiouner Pro V2.
Anyway congrats for your discover, Pavel

Needs "DualTiouner" software never produced, only announced.
Great Job. Roberto IS0GRB.
You make the difference in our hobby.
I try to decode the 1,500 WB Bacon. [90cm mirror, LNB-unmod/POTY Vers. 2. 0. 21] with PLUTO. NB (RX/TX) works fine. The IP Plot does not show circles, although there is enough level. So the decoding doesn’t work. Where should I look?
try to reduce gain, anyway, it takes a lot of time to lock the constellation (10-15 sec in my case). Parameters seems ok but there's an anomaly in the Bandwidth parameter. You have to see a grey band that cover the centered signal. I dont' see this greyband, may be 500000 is too much. Try to tune without changing the bandwidth, leave the same value showed when the app is open first time.
73 and regards.
Anyway HS Modem is a great Software thank you DJ0ABR.
installed 0.72 today but can't get the sound working. using VB_Audio Cable, I have the free single one and the additional a+b installed.
Hardware is a Pluto with SDR-Console on a Laptop with i7 CPU running win10 64Bit . The Audio cables are working fine with several other programms i.e. JTDX, fldigi, KGSTV, MMSSTV but hsmodem don't like them. I tried several setting like 48K, 44K1 both with 24 and 16 bit but no success always looks like below
In the Voice Audio TAB looks the same I get the red sign don't madder which Speaker/Headphone/Microphone is selected
in the "Treminal Window" I see a list of all my connected audio devices including the 3 VB Audio cables but always get output below.
QO100modem initialised and running
restart modem requested
Start request for CAP stream:CABLE Output (VB-Audio Virtual Cable)

Any hint is welcome.
I have been eperienced the same "issue", but in my case, selecting the last check box, to start the transmission and reception of DV (This is in the same page, of parameter show in tour post) , the red cross move to green tick. In my opinion, the app doing the check of audio parameters only when you select a mode to use the digital encoder.
After this all run well.
Please try this and tell me if the issue is solved.
Thanks Jean Pierre, January 13, 2021 I downloaded the program the first to receive was Frank DD0CW SR25 16APSK and I had a great surprise of the program you have created an excellent program COMPLIENMTI

My observation is that Robert has an excellent emission at 16psk 25 K/s. Until now he's the only station that I can read perfectly. This not happens with other station, may be that my system has issue to decode at 16PSK when a signal is "dirty" or with TS broken.
The new parameters in Minitioune don't help to read other station, instead DVBS_GUI at lower speed show unexpected performances.
Anyway I need time to improve my setup.

Thank you JP.
To announce you this time a new patch (UII2.3) which brings these new functions:
- Multiple modulator profiles (I worked hard)
- Transmission time counter
- Internal temperatures
- Focus on null packets on the analysis page
- Github commits history
After some days of feedback and then maybe correction, it is likely possible that a complete firmware will be available soon.
Your remarks and feature ideas are welcome on
Great Job Christian, thank you very much for your effort.
I've a OPTICUM LTP 04H but I have different request for the modification. My aim is to maintain the second output, and drill a hole to take 25 MHz to the chip. Would you examine my schema to check if it's correct ? Thank you for your answer,
I leave the resistor, delete the wiring, cut the track and connect 25 MHz source to the point showed by my arrow. I will connect a small coaxial cable with gnd connected in some point were available.
I Agree with Mike. To avoid amplifier crash, it's important to define a limit,.
Also useful a possibility to save a "transmit profile". This is useful to load quickly, parameters for each speed selected.
(PCR/PTS, PAT, MODE, FEC, Pilots, Base frequency, Modulation, Frame etc) eg Button Save Profile, name file.
Corresponding to this button another "Load Profile" drop down menu to select the profile, and load automatically saved parameters.
As told Peter, AO40RVC works only for message, no telemetry. Don't use Nino Porcino Decoder, with Win10 in my case won't run due to lack of libraries.
Helix Antennas are broadband by design, so an thick wire is not really needed. To be mechanically stable, it is better to use a plastic holder to support the wire. This example of my helix is built using 1mm Wire, supported by printed PETG holders and is very broadband as you can see. Impedance matching is done by a metal vane wich can be easily bent to get perfect match. Five windings give you good circular polarisation and high gain. Combined with the LNB in the middle of the Reflector, LNB loss is very low (about 0.5 to 1 dB)
because of very low shadowing the LNB by the thin wire.
