@SSSRC_HIROGARI successful receive of OPUSAT-II CW telemetry. Reported to Hirogari RX report page and diploma downloaded, thank you!

I have used the following hardware and software:

  • RX at aprox 145.900 MHz CW
  • 2 * 6 el RHCP VHF Yagis from Vårgårda
  • AlfaSpid RAS az/el rotor
  • LNA Mini-2 from SHF Elektronik
  • LMR-400 coax
  • Airspy Mini
  • SDR-Console v3 with doppler correction of downlink and satellite tracking, rotor control
  • PstRotator for rotor control interface between SDR-Console and RAS controller
  • VB-Cable: virtual audio cable for piping audio from SDR Console to FlDigi. Set to 96 kHz and 16 bit.
  • FlDigi for CW decoding

VFO control for SDR Console Satellite External Radio

In SDR Console v3 it is possible to control an external radio for transmitting (TX) in the satellite mode – this is called External Radio control. To change frequency you can click on the digits in the control window with the mouse pointer or change with the arrow keys, but it is not possible to use any other shortcut keys or VFO knobs.

This solutions adds a AutoHotKey script for remapping and controlling both RX and TX VFO and a software remote VFO with the help of Unified Remote software. You can use these independent – but best is together. If you only use the AutoHotKey script then you can toggle between the RX VFO and External Radio TX VFO and control with the arrow keys. If you only use the Unified Remote you can control the RX VFO but not switch to the External Radio TX VFO.

Files and instructions can be found at Lars Thunberg SM0TGU GitHub.

Cloudlog – log your sat QSOs

Cloudlog is a QSO logging software developed by Peter (@2M0SQL) installed “in the cloud” – on a web server – and used via a web interface. It is perfect for fast logging of satellite QSOs as Peter is a well known and experienced satellite operator.
This is a very short introduction of Cloudlog.

Installation:

Cloudlog can be installed for free (do not forget a donation to Peter!) on your own web server or server host. The installation instructions are very easy to follow. If you do not like to install by yourself you can buy a purchased subscriptions.

Logging QSOs:

Logging can be done “Live” or “Post”. As I still using a pen for writing down my contacts, I use the Post QSO.

Cloudlog is fully prepared for all type of satellites. All settings are saved for the next QSO you would like to log, so if you are doing a lot of contacts over one satellite post-logging goes very fast.

Sync to LOTW

Syncing to LOTW can be done via script or manually. I’m using the manual sync and it is working perfect. You can also see if you get a confirmed LOTW contact in Cloudlog.
