Assorted ramblings from the developer


Es'Hail 2 Beacon
Es'Hail 2 Beacon

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.

  • ELAD S3 - It's Here Posted 3 weeks ago
    Yesterday I integrated SDR Console with a beta S3 receiver from ELAD. My first impression is that it's a terrific receiver and will be of great interest to SWPs, DX-ers and government origanisations. I'll make some videos later. With the front end wide-open there's no overload at all, despite a few close medium wave transmitters. A couple of screenshots: Manx Radio - 1368kHz   General Shortwave with a 20 MHz bandwidth!   Stay tuned for more updates.
  • Release: 3.0.17 Posted 3 weeks ago
    Download here [Link]. External Radio Added Up-converter offset support, used with Es'Hail-2 (QO-100). See: https://www.sdr-radio.com/Console/EsHail2   External radio window displays “Starting” while OmniRig is initialising. General Ensure all program components start sequentially: When DX Cluster is configured to starts when the program is launched it will no longer allow other processing until the cluster connection is established. DX Cluster and the External Radio were starting simultaneously and this was causing the program to freeze. Added sanity checks when defining filters:   Remote server: the connection window below is now much faster, especially when the remote server is hosting more than one SDR.   ANAN 10 – better (not perfect) display of output power. User calibration to come in a future kit. TX Meters now work better when automatically adjusting displayed ranges. TX display of ANAN PLL status changed to indicate when the PLL is stably locked. Remote server web page updated: https://www.sdr-radio.com/Software/Version3/Server LimeSDR Updated support library to latest Github code.
  • Release: 3.0.16 Posted last month
    Download here [Link]. Important changes for QO-100 user, see below. What's new / changed in 3.0.16: Display DX Cluster bug fixed so the connection / non-connection can always be closed. Added 'Always On Top' option when, when selected keeps SDR Console on top of all other applications.   The font used at the top of the RX and TX window has changed from non-proportional bold to proportional normal. This kit correctly saves / restores the collapsed / expended state of the panes in the RX and TX DSP panels. Added Program Lock.   With very high zoom levels the interpolation changes to use a cubic spline, in the image below see how round the spectrum curve is.   Converter Definitions Now support a TX offset as well as RX. The TX offset is shown at the top of the TX DSP panel.   The TX offset option has been removed. Has a QO-100 button which prepares a standard QO-100 definition. This affects QO-100 users - see https://www.sdr-radio.com/Console/EsHail2 and scroll down. Existing definitions are kept (not lost). ...
  • ELAD S3 - Soon Posted last month
    With any luck I'll have an ELAD S3 next week. Here is V3 playing a recording made by Nils, DK8OK using his S3. 24 MHz wide recording, 19.4 MHz usable!
  • Hermes Lite 2 Posted last month
    The Hermes-Lite is an outstanding low-cost direct down/up conversion software defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR project. If you are looking for a small QRP transceiver with excellent performance for the price then consider HL2. Below are images of the build 9 boards published on the Hermes Lite mailing list by Steve KF7O. For more information visit the Hermes Lite page.
