#HamChallenge Week 44: Receive a QRSS signal on the HF bands

Inspired by an article in CQ DL (monthly magazine of DARC) I used now and then the software FSKview to monitor the #QRSS in the #30m band.

I definitely saw some QRSS signals (examples in the pictures below). However I find it very hard to visually decode these signals. I haven't yet decoded a call sign with certainty. Therefore I do not yet claim success for this challenge.

#hamchallenge week 48: Transmit a QRSS signal on the HF bands. After the receiving challenge, let's transmit! For starters, you can hand key your signal and check if you can see it on any of the many grabbers that are online 24/7. See https://qrss.org/ for more information! https://hamchallenge.org/2025/48 #hamradio #qrss

#hamchallenge week 44: Receive a #QRSS signal on the HF bands. Check out https://qrss.org/ for a list of frequencies and fire up a QRSS grabber software like Argo (I2PHD), Spectrum Lab (DL4YHF), LOPORA (PA2OHH) or QrssPiG (HB9FXX). There are signals transmitting 24/7 on most bands that are easy to copy. #hamradio

Work in progress. A two band QRSS/WSPR beacon with a RPi Zero 2 W as the controller, two Si570 (I have too many of them left to buy any of those new Si5351 etc.), a LVDS to TTL converter (yes, those Si570s are the LVDS version), some BSS138 (class E PA a la G0UPL) and LPFs. Everything fits into the same nice 10cm x 10cm enclosure I used for my last project (SO2R Mini+). #hamradio #qrss #wspr

Good conditions on 30m last night. For the first time my #QRSS grabber at SO5CW received KQ9RSS from Decatur, IL, who is transmitting 200mW to an attic dipole. #hamradio #propagation

The sun is very unsettled today. The #solarflare at 13:28 UTC today was very nicely visible on my #qrss grabber on 10.1 MHz #hamradio

I made some software rendering pixel fonts into audio and I TXed a #qrss signal. RXed my own signal from the grabbers, plus some common British beacons on 30m. Does this count as a threefer for the #hamchallenge? (44, 46 and 48).

Never not watching the #QRSS grabbers. Greetings from OK/DJ5CW/m on the bus to Budweis... #hamradio

After trying to manually correlate propagation events I saw on my #QRSS / #WSPR grabber with the solar flux data from the #NOAA #SpaceWeather Prediction Center for a while, I wrote a few lines of Perl that simply plot the current data below the grabber output... https://fkurz.net/ham/qrss/30m-24h #hamradio #propagation
