PS: In the same window, you may like to disable the amplitude ramp function which is only useful for linear PAs at LF/MF, if you want to reduce key clicks.
BTW i just started a short DFCW-5400 message at 80 Hz :-)

Hi Tom,

In the digimde terminal, press Settings and then digimode configuration. Then there is a field for the symbol rate. For QRSS-6000, set that rate to 1/6000, i.e. 0.0001666.
Above, there is a field for the DFCW shift in Hz.

Hello group,

does anyone of our VLF-/ELF-freaks know how to modify the original SpectrumLab program for sending and receiving much lower speeds on QRSS and especially DFCW? The upper limit now is 60 seconds per dot - much too fast for working dx at VLF/ELF and for most of the active grabbers. 600, 3000 and 6000 seconds per dot would be desirable. Any ideas or ..usr-files?
Yes, I know EbNaut and all the other self-acting modes being
alternatives - but I want to try it anyway ...
Tu es 73,
Tom, DK1IS
