2016年7月12日 · Double click on qrq.exe to activate the program. This 0.2.1 version does not "install", it just "runs" in a terminal command box.] "QRQ's" new features allow unlimited repeats of the last word that was sent, setting the pitch, rise/fall time, and fixed cw speeds... making FABIAN's "QRQ" absolutely one of the best ever !

Interrupt Modulated(IM) QRQ CW Mode transmitting and receiving digital information using an analog carrier where the required bandwidth is limited to approximately the frequency of the analog carrier signal. The method is called interrupt modulation and consists of interrupting an un-modulated carrier signal so the… Continue

2011年6月25日 · 3.) If you can't get on the air, and are forced to listen to canned, pre-recorded QRQ, then use actual QSO's you recorded off of the air, round tables or one on one sessions. When you can listen to your recordings and no longer need to concentrate on the CW to know what is said, then you have memorized them and they are now stale.

2016年11月29日 · I have been keeping on the air skeds with some old masters of QRQ for a while. I would encourage anyone interested in QRQ to get on the air with a like minded soul. While I do use my mp3 files and Fabians 'QRQ' program for practice, there is nothing like an on the air QSO to challenge my receiving and sending skills.

What sidetone frequency range (or VFO/BFO receiver offset) will allow one to copy CW when trying to learn to copy QRQ? (high-speed Morse code, 40 WPM and higher) It seems like there will be very few audio waveform cycles in short QRQ dots when using a very low tone frequency at a very high WPM, so why might some CW operators say they prefer that?

2020年3月16日 · Also, does QRQ CW require the operator to slow down to 20 WPM every 10 minutes to ID? The answer to both of those points is no. Think of all the CW signals on the bands that are 40 WPM and higher. There are no present laws that require them to …
