Rich:
I dont use Digpan much, but I do not think that signoff inaccuracy is solely
due to any Computer system clock setting. Remember that the PSK31 spooling
rate is, I think, about 25wpm, and some operators type at a somewhat higher
rate than that.
Even with a perfectly synchronized computer system clock setting there are
other reasons why an apparent inaccuracy of the signoff PSK31 time is
received.
With other programs that I do use, the sign-off inaccuracy might very well be
due to the amount of transmit data that must yet be processed (at 25wpm rate)
prior to reaching the Rx command within the xmit buffer.
OTOH, I will check out your suggested URL. After running Scan Disk here, I
find as much as 30 minutes offset between my computer's system clock and the
WWV NIST clock. If the suggested "gem" is a way to compensate automatically
after accessing my ISP, then I will give this serious thought. Thanks for
your info.

Subject: [psk31] 6M Operation
Hi Gang:
I've noticed a tendency for 6M psk ops to frequent the area around 50.300
and feel this is a poor choice as it is the High Speed Meteor Scatter
calling frequency (worldwide, I believe). How about moving up to 50.325zb
or 50.350zb where little if any operation occurs. I plan to use .350 with +
800 hz o/s myself. Hope to see you guys there. We have so much space on
this band that isn't being utilized. Lets give the hsms gang a break!

Subject: [psk31] Unusual PSK31 Configuration
Hello All,
I am using a very unusual configuration that might be helpful to others : I
use the line out of my FT-840 to the line input of my sound card as usual
but I take the output of the card into an aux. input of a Pioneer Stereo
receiver. The line output of the receiver is then fed directly into the mic
input of the 840 (no attenuation needed). I have had several hams tell me
the resulting audio on the air to be very clean.
So, if you have an old receiver around that you are not using give it a
try. Let me know how it works for you.

If you are using or plan to use a Rigblaster wih a laptop please note that
several brands of laptops may not have sufficient drive from their soundcards
to drive your radio properly with the RIGblaster configured as is. If you
are having problems with your RIGblaster and a laptop computer please contact
me for the fix.

Someone suggested 50.331 31 for PSK31. Sounds good to me

I have been running DigiPan with a Kenwood 430S, RIGblaster, Ensoniq
soundcard, and a 200 MHz Gateway full of all kinds of programs, under
Windows 95. I have had the hang-receive problem as well as an unreadable
waterfall display (display looks as if there is wall-to-wall loud band
noise). I have found that a machine re-boot cures all the problems
instantly (well, as long as it takes to re-boot), until the next time. I
suspect the computer/operating system/program conflicts rather than the
PSK31/rig/DigiPan, since the computer would hang from time to time, and do
other strange things, long before I started PSK31 two, three weeks ago.

Hi Bob. That problem sounds like it is either a computer problem or
software problem. There is
a slight possibility there is a glitch with your software. Maybe try
re-downloading the software
again and see if the helps.
I have a Kenwood TS-450. Was in a QSO yesterday when the Digipan software
started to cut back
to receive even though I was xmtg. For several tries it would start to xmt
and then go to rcv. ????
Maybe the authors of the program have some suggestions...

Golly, seems that everywhere we go, someone is already there!
I'm wondering if there isn't some clearinghouse for such things. Not in any
regulatory way, but in a strictly "I heard from N8AVX that the frequency of
1244.355 is used for backscatter communication utilizing the reflections
that occur when a large flock of metallic leg band tagged geese fly over"
kind of thing.
;-)
I wonder if PSK31 could be successfully used in such an activity....
High speed meteor scatter I mean, not low speed leg band scatter...

Subject: [psk31] How to set up on a new HP computer ? - sound card has no "line out"
Hello: I just got a new computer that I wanted to set digipan up on. But,
looking at the sound card, it does not have "line out." It has a mic , a
"line in" and a "speaker" but now "line out."
If I go directly from the speaker output, I would be seeing 8 ohms or so to
my patch in or mic plug. I need about 500 ohms. I think radio shack has a
transformer that does 8 to 600 ohms or so, but wondered if there was anyone
out there who ran into this problem.
The other solution was to buy another sound card and plug it in as the
computer has spaces for new cards, and I imagine that a new card would not be
that much. It seems a waste, however.
Any suggestions would be helpful. I don't know if Radio shack has an
impedance transformer from 8 to 500 that is already built up or not.
