K3 - Data A pitch

Seen this asked before but without response so does anyone know if it's possible to change the centre frequency of the audio in Data A?

It's about 1500 Hz at the moment and wouldn't mind being able to drop it a bit unless there's a good reason not to.....?

Also my (old) manual suggests you should be able to use the dual passband filter for rtty while in Data A but I assume this was a mistake?

Yes, just set the SHIFT and WIDTH controls to your liking.

DATA:FSK or DATA:AFSK only.

But if you do that, you won't be able to take advantage of your narrow
filters for PSK31 etc. because your filter will fall outside the passband.
Looks to me like you better leave your FC where it is at 1500 Hz unless you
like hearing wide spectrum and don't mind the QRM.

Re: K3 - Data A pitch

Please pass over my previous post about pitch. You can indeed change FC and
retain use of narrow filtering. Just remember to change the FC in whatever
software you're using.

Re: K3 - Data A pitch

In reply to this post by KK7P

Lyle,

What I was looking for was being able to control the pitch when I hit the XFIL button, like in AFSK A and CW; in DATA A this centres on ~1500Hz. Presume this is a function of sidetone frequency.

However using HI/LO CUT works just fine and I can store this in one of the per mode filter pre-sets. Haven't checked though whether this pre-set will get overwritten by the AFSK A settings - normally use rtty/AFSK A in data but getting sorted for an RSGB data contest tomorrow evening in which the rules now mean you have to use both PSK and RTTY if you want to maximise your score.....

Thanks for the reminder about HI/LO cut.

73,

This is not adjustable at the moment.

However, you can set up a pair of preferred settings using the NORM
(hold) function of the WIDTH control. See page 24 in the K3 Owner's
Manual, Rev D2.
