Assorted ramblings from the developer


Release: 3.0.7

Download here [Link].

What's new / changed in 3.0.7:

Data Recording

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.

LimeSDR Calibration

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.

General

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.

    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.

    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 Enjoy!
  • Es'Hail 2 Beacon Posted last month
    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.  
  • Release: 3.0.6 Posted last month
    Download here [Link]. Note: 3.0.6 fixes / enhances the support for Lime and PlutoSDR. What's new / changed in 3.0.6: Data Recording The WAV file format upgraded to WAV RF64 which supports an unlimited filesize, previously the maximum filesize was 2GB. No more XML files being created. Analyser updated and tested, seems to be OK with these big single-file recordings. Tested with 3rd-party recordings: Perseus, ELAD S2. Redesigned the Playback Select window (below). If you have a lot of recordings this is should be better to use. When you make a new recording the individual filesize is now optional, if not enabled then a single file is created. General Fixed a bug which had been in the code since day 1 (about 4 years ago). As this was thread-related the crash happened rarely, depended on CPU speed and other factors. Restarting a radio/recording could cause a crash due to bad thread synchronisation: Changing radio bandwidth, Starting recording after the radio was running, Starting radio after playing the radio. Default stack size now 2MB (was 1MB) Added a Mute option ...
