Subject: Help on EPROM, D/A circuit??
If this is not the proper Group, please
pardon my intrusion...
I'm building an arbitrary waveform
generator to time-control the gain of a receiver.
It uses a ring counter which sequentially
addresses an EPROM. The 8-bit wide
EPROM output is fed to a D/A converter,
so that the analog signal out of the D/A
is an arbitrary voltage depending on the
memory previously written into the EPROM.
Can anyone suggest where I can get a
schematic suggesting part numbers??
The EPROM will be about 8x256 bits.
Thanks, Henry

Subject: psk31 problem w/sound card
I sure need someone to help. Am using Windows 95 and have a soundblaster
pro sound card. When clicking "Set Up" on psk31 I keep getting an ERROR
message: "SOUNDCARD MMSYSTEM032. The specified format cannot be translated
or supported. Use the capabilities function to view supported formats."
I have talked to microsoft and to creative (soundblaster) about this and
noone seems to know anything.. Can anyone help???? W7EQ Gordon

Apparently your C compiler processes a language that resembles C. But
does it also accept the following correct C program?
#include <stdio.h>
int main ()
{
int i;
i = 6 //* divided by */ 3;
printf("%d\n", i);
return 0;
}

Subject: Two soundcards
Has anyone managed to successfully get two soundcards to work
simultaneously under W98 ? I am using a Creative SB card but have
also an integrated yamaha system in a Dell Pentium II 350 mhz PCI
machine. I would like to run one of them as a dedicated FFT card
while using the other for RTTY/PSK etc.
Has anyone any information on how to go about this ?
If I get any useful data I will post a summary to this group

Subject: XPWIN and TNC-2 clones
Can anyone give me guidance as to setting up XPwin and a TNC-2 tnc.
This seems to fall in to the dumb terminal mode but there is no real
documentation on setting it up.
Thanks from G4BBH
