GRABBER FOR 30 METER QRSS BEACONS
(2011)


The QRSS beacon reception station with frequency standard locked at
BBC Droitwich 198 kHz or Allouis 162 kHz for the frequency calibration.

The receiver is the "IMPROVED 30 METER RECEIVER FOR LOW POWER QRSS BEACONS AND PSK31". A detailed description at the following link:

Improved 30 meter receiver for low power QRSS beacons and PSK31

This receiver has been improved again by inserting a crystal filter and some measures to avoid radio interference from the PC. This can be found at the following link:

Crystal filter for the 30 meter QRSS beacons receivers

For the frequency calibration of the receiver, I do use the solution that can be found at the following link. There is a solution for a frequency standard locked at Droitwich (198 kHz) and one for Allouis (162 kHz):

The software can be found at the following link. I do use the LOPORAv02b.py version. The "b" version has the 24h archive:
