I wrote this program because I wanted to see:
Current Time (local, GMT)
Sunrise / Sunset
There are commercial geo clock solutions such as the excellent Geochron, but as a programmer with spare HD monitors and computers I decided to write my own, that way I have exactly what I want.
Anyway, this weekend I finally found time to update Simon's World Map to version 1.0.8. Here's what is new:
Installs a 64-bit executable on 64-bit Windows, previously the 32-bit executable was used on 64-bit Windows.
Text colour in Clock, Sunrise / Sunset etc. is user-selectable.
Sunrise / sunset shown for entries in the station list.
Timezone markers updated
It doesn't need much CPU at all- anything running Windows 7 or higher is fine.
Listening to France Musique, a station whose output is sorely missed in the UK.
Using the latest little stunner from Airspy.
Download here [Link].
Note: The main reason for this release is the fixes to transmit with the Pluto SDR.
What's new / changed in 3.0.9:
Screenshots taken with a prototype Airspy HF+ Discovery. This beauty is half the size of the Airpsy HF+ and it's as good if not better. Proper comparison data later.
If you suffer from strong signals then Discovery will not let you down.
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.
If you want to take a break from DX on the ham bands, why not try Band II DX?
Version 3.0.8 (coming soon) has an automatic log of received stations.
More information is available here.
What's new / changed in 3.0.7:
The WAV file format upgraded to WAV RF64 is only used if the file size if set to a value greater than 2GB or unlimited. File szes of 2GB or lower use the original WAV format and will be compatible (should be compatible) with other 3rd-praty programs.
Es'Hail 2 Beacon
Added Beacon synchronisation: https://www.sdr-radio.com/Console/EsHail2#TelemetryBeacon . This is an option to using a TCXO or GPSDO and is used to compensate for LNBs which are not stable.
All Lime-relation calibration options are now user-configurable. The option of changing the offset frequency has been added. Some brief tests on 2m show that offset tuning may not be needed.
TX calibration should ideally be run when the drive level is changed, this affects the Lime internals, so maybe the option of running TX Calibration automatically when the drive level is changed should be added?
Note: you cannot properly monitor your own signal using the same device that is transmitting.
Improved performance when scrolling the receivers – there was unnecessary processing when scrolling in a receiver window.
Serial Port (CAT Control)
WSJT was not working correctly, the serial port (CAT control) has been updated software and tested with WSJT.
Just saw a tweet from @robinlgetz - this is an excellent offer.
2019 Hands-on workshop using Software Defined Radio, across the US and Canada. Take home a #plutosdr , “Software Defined Radio for Engineers” text (pdf) and trial of MATLAB. For more information, check out : https://secure.effreg.com/r/sdrworkshop19?1
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.
Note: 3.0.6 fixes / enhances the support for Lime and PlutoSDR.
What's new / changed in 3.0.6:
The WAV file format upgraded to WAV RF64 which supports an unlimited filesize, previously the maximum filesize was 2GB.
When you make a new recording the individual filesize is now optional, if not enabled then a single file is created.
USB Relay support
Using Es’Hail 2
Look at the screenshot:
Here you see the down converter setting for a LNB:
