KF>> What is noise? If you dial through the speaker, forget it
KF>> not a driver at all or a buggy motherboard.
KF>> I repeat once again that no noise should be detected from the #fe port
KF>> none if the pipe is raised and the line is quiet. If there is, then none
KF>> the driver will not help - you need to reduce the gain and noise.
DL> nope. the noise will still be there. if you reduce the gain, it will not work well.
DL> the noise is not very disturbing. Cod in the line interferes. although this is also noise...
Yes, but in a good Wikomnik there is almost no noise. Not like in XTR.
I don’t know why, but there shouldn’t be any noise in _VIKOMMNIK_.
By the way, the noise is very disturbing - the FREE_LINE function in the driver
slows down immeasurably. And of course, the beginning of a block is not always good
recognized. And if you reduce the gain, it won’t necessarily happen
bad. You can choose it so that there is no noise and everything is ok.
I think it's a matter of the specific amplifier circuit. In XTR it is noisy, but in
Wikomnike - it’s different for everyone.

AK> Damn, I'm not just saying that.
AK> Set mdriver+ - there is noise.
AK> Set mdriver- - no noise.
AK> I don’t even know how to explain. It's not really noise, just a kind of buzzing

AK> by lifting the pipe. I myself tried to lift the pipe from the monitor by
AK> sending a byte to port #fe - no noise. And in the bbs there is. :-/
You don't even know how it works. 3 bits is the output to the mafon.
In Wikommnik he simply connects +5 volts to the trance.
(if you don’t understand, see what DS wrote about its driver)

KF>>>> there shouldn’t be any noise! Be sure to pick up the motherboard and ground the computer. AK>>> Oh! Exactly. And how to ground it, in the sense of where to remove the earth and
AK>>> plant on the body ?
KF>> The computer has a common wire to the battery. Just don’t “ground” it on
KF>> zero from the socket...
AK> So where to get the land from the power supply?
From a flower pot! I wrote - to the battery.
You can still tear off the paw of the trance responsible for
reception and connect through the trimmer and twist it.
