Here's a screenshot of my Pluto SDR on Es'Hail 2, this screenshot shows the suggested settings for pluto(bottom left-hand side).
Note the RX Gain is set to Slow Attack (Manual value is ignored) and the Visual is set to -40dB.

Note: The main reason for this release is the fixes to transmit with the Pluto SDR.
What's new / changed in 3.0.9:
What's new / changed in 3.0.8:
New features and changes for 88 - 108MHz FM broadcast reception and the RDS decoder.
RDS decoding has been improved by making PI code detection mor sensitive.
US Callsign logic now uses data from NRSC for callsign and location.
Spectrum window now a docking pane. Display the spectrum window by selecting Ribbon Bar, Receive, Broadcast FM.
Logging of station from the RDS decoding has been added, this is the RDS Logfile option. To display the logfile click the Log button in the BFM Spectrum.
The logfile has all the options you need:
Click ••• to display the options.
The Airspy options have moved from the ribbon bar to the Receive DSP panel.
The USB relay terminology has been changed to avoid confusion.
Data (IQ) Recording
Playback now correctly detects ELAD recerdings and displays the format as ELAD. later the contents of the elad chunk in the WAV file will be supported.
AOKI URL updated and new format supported.
Font size selection for ageing eyes.
Defauly field order changed, will be user-configurable in a future release.
The sample rates 192kHz, 96kHz and 95khz are now calibrated.
Tidying up and extending the Select Satellite option. Instead of just selecting a satellite, pressing Select in the Satellite ribbon bar now display the Select Satellite window which provides an overview of the entries in the Satellite List as well as selection of new satellites.
Footprint configuration is now consolidated into a property page.
Uses the original version 3 de-emphasis and has better peak volume control.
Problems with the transmit signal bursting reduced by redesigned inefficient code, see Pluto support page for more information.
Just saw a tweet from @robinlgetz - this is an excellent offer.

There's a big problem with consumer LNBs - they drift, and drift badly! One way of correcting this drift is to monitor the telemetry beacon, determine the actual received frequecy of the beacon and hey presto - we have the offset!
Quite a bit of coding involved, but when you decode BPSK you actually have the offset if you pay attention to the code. Add a nice waterfall so the user can select the beacon, add a bit of funk and we're more than half-way there. Here I'm plotting drift versus time.
Also it's nice to see Es'Hail 2 being used more as people get their systems together.
Code will be in 3.0.7 - within a week I hope.
Here's a screenshot of a 'hacked' Pluto transmitting a two-tone signal as received by an Airspy HF+ (probably the best SDR you can buy for reception at 145MHz). As you see, the transmission is nice and clean.
Here's the two-tone setting.
After 10 days of very interesting programming the pluto project is ready to be released into the wild now that basic transmit support is ready.

Here's three FM Stereo signals being demodulated along with their RDS.
Here's a screenshot of Pluto receiving FM Stereo.

The PlutoSDR is running smoothly with a 6 MHz bandwidth. Plenty more coding needed, but at least it works.
For testing I'm using my 2.4 GHz Wi-Fi signal. Click on the image below for a high resolution image.

Last Friday I purchased this small SDR. More updates when it arrives.
