Hi Rik the only problem with your "inter-europe" frequency is that it clobbers anyone listening for transatlantic signals. I would suggest restricting operation there with a signal the size of Chris's to daytime and early evening. He should easily make one hop (2500km) paths into Europe and get into get into the Russian grabbers, leaving the late-night and early morning for reception of T/A signals. To try the T/A path use 136.125 (I think...I'm out of practice :-)) )
 
Chris, Rik did not plug it but he has an excellent tutorial on QRSS and DFCW on his web site.

Hello Chris,

 

Frequency:

inter-Europe QRSS (good to start with) is centered around 137.7kHz

 

USB or CW:

depend how you generate the signal.

CW if you key the TX, USB if you use an audio tone.

The result (TX signal) is the same. Both are possible with the QRS software. For DFCW audio tone + USB might be the most convenient.

 

Dial frequency:

depend on the mode.

For CW the dial frequency = TX frequency.

For USB the dial frequency = TX frequency - audio tone.

 

Dot period:

most common is 3 sec/dot. 10 sec/dot for weaker signals.

For transatlantic test 30 to 120 sec/dot is used.

 

Call sign: just clear text. For QSO's it is common practice to use the suffix only once both calls are confirmed.

Eg:

you: CQ 2E0ILY K

me: 2E0ILY ON7YD K

you: ON7YD ILY MMM K

me: ILY YD OOO K

you: YD ILY TU SK

me: 73 SK

 

73, Rik  ON7YD - OR7T

I want to try using QRSS on 136 kHz and have a few basic questions if
I may?

I have made a keying interface for my TS-590 exciter, but not sure of
the following:

What frequency should I use? Just leave the dial frequency at 136
dead?

Do I set the exciter to CW or leave in USB mode?

How long should I set the dot period for? I assume this corresponds to
the QRSS "mode"?

Do I just enter my call sign as the text?

Do I need to just look at various grabbers on line to see who, if
anyone, picks it up?

Anything to be careful of, etiquette or technically speaking?

Thanks, software is ON7YD's "QRS".
