Subject: [psk31] Keying Methods?
Just this evening, I did a little research on voltages on my COM 1 serial
port. I knew to expect 'high' (i.e. postive) when keyed and 'low' (i.e.
negative) when resting. However, I was expecting 5 vdc rather than 12vdc.
You learn something every day. With this is mind, is there any reason you
couldn't use a small 12vdc relay, with appropriate blocking diodes, to key
the xmiter for PSK31?
Let spirited debate begin!

Subject: [psk31] PSK31 & Windows NT
My problem is with the NT Workstation. I can't get the PSK31 to work.
The tuning scope shows only a red dot in the center no matter where I
tune around to.
The water fall stays completely black and doesn't change either.
I need some help!!
I swap in and out 2 physical hard drives on my pc.
One hard drive has Windows 98 and the other hard drive has NT
Workstation.
I have no problem at all with the Windows 98 hard drive using the PSK31
Version 1.08
by P. Martinez G3PLX. Everything works like it should.
The settings are the same on both hard drives:
Sample rate hz. 11025
Center afreq. 1000
PTT None
The sound card does function with NT.
Version 1.08 says that it will work with NT, but I have been unable to
make it happen.
Any suggestions on getting NT to work with PSK31??

Hi all
A friend is trying to get PSK31SBW to run on his 486DX40 with
4MB ram and an ESS1688 sound card. Operating system is Windows 3.11.
The sound system works fine with normal windows applications.
When the software is set for the default sampling rate it locks up
before the full screen display is finished loading. He tried
reducing the sampling rate to an arbitrarily low 3500 and the
program was then able to load but the sound card would not work.
Question is - does this sound like a problem of:
a) processor speed too low;
b) insufficient RAM;
c) incompatible sound card;
d) incompatible operating system?
Ideas please?
Thanks and Merry Christmas to you all.

Most ports supply +/-12V. However others supply less (+/-5V is not
uncommon on some older laptops, for example).
RS-232 drivers must provide 5V into a 3K load... this is a 1.6mA at
5V. At 12V you'd expect less -- so you have to be careful how much
current you draw. Of course, your port may (or may not) supply less.

Hi Daryl,
Sounds like you're having the same problem I had with NT. Open the Volume
Control in the system tray (the speaker icon) by double left clicking it.
This shows you the full volume control panel with multiple sliders (if you
don't have the icon, open the COntrol Panel, Multimedia, Audio tab, and
check "Show volume control...").
On the Volume Control, make sure the Mute box is unchecked, then adjust the
microphone slider until you get the waterfall and tuning displays at the
right level (short of going red, which means your overdring the sound
card). If you don't see a Microphone control, go to the menu and pick
Options, Properties, and make sure all the controls on the list are checked.
If you are using Line Input instead of the Microphone input to the sound
card, do the above with Line Input.
On my system, the Microphone volume control was hidden until I did this.
Then I discovered that it was muted.
I've also run PSK31SBW under Win98- the mike seems to be enabled by
default, which is why PSK works out of the box without having to go through
all this.
Good luck and 73

Daryl, I've been looking at the details of your post trying to glean clues
as to why you're not getting PSK31 to work with NT. I am running it quite
successfully here on NT. Granted, I am running NT Server rather than
Workstation, but I doubt if that is significant.
Sounds like audio is getting into the sound card but resulting only in the
red dot in the center. You say the sound card is working, but have you
tried to feed a audio signal into the same input (of the card) and hear it?
I'm not providing good help here, I know, but at least you will know that
the program will work with NT.

The RS-232 port does not deliver much in the way of current. So unless
you find a really sensitive relay, don't plan to drive it directly.

Why not use a simple circuit using a transistor and a resistor? I use one
here to key my amplifier using the 12 volts out on the rear of the TS-850.
