Re: LF: Soundcard frequency calibration for 8.97kHz tests

[Roger Lapthorn <rogerlapthorn@gmail.com>]

Many thanks for this information Wolfgang. 

When my grandson goes back home and I get my shack and main PC back (!) I shall try to implement this in readiness for future 8.97kHz tests both from here in the UK and from Germany.

Hello Mike and the group,

Thanks Wolf, I will wait for version b11. How soon until you get it published? hi hi...

I have now published it, as a 'Beta' version, here:
http://dl4yhf.ssl7.com/speclab/install_speclab_beta.zip

('subject to frequent change', this one is actually Spectrum Lab V2.75 b11 "BETA". Saving audio as Ogg Vorbis files doesn't work yet, thus the 'Beta' status; but it doesn't matter for this application)

There is also a quick and dirty writeup about how to use the 'very slow' QRSS modes, with and without the sample rate correction via MSK transmitter :

I haven't checked the proper function of the preconfigured "600 second / 1 mHz" (milli-Hertz resolution) setting yet, but it should be very similar to Markus's setting. How to recall this setting through the 'Quick Settings' menu is described in the article above. And no, you don't need a PhD to get it working ;-)

See you later,
