Re: psk or PSK

It takes a little bit longer for psk31 to send a CAPITAL LETTER,

To test my theory I typed the same macro in both upper and lower
cases...it is a
surprising difference in speed!

Duncan (and others) -

You are exactly correct. The actual speed of characters is dependent
on the distribution of letters in the text, but on average, capital
letters are 2-3 bits longer than lower-case in the Varicode used in
PSK31.

I think lower-case letters average about 5-6 bits each (averaged over
English text), and upper-case about 8-9. This has the two effects
Duncan mentioned:

1. At a rate of 31 bits per second, lower case will produce about 5
letters per second, versus 4 letters per second for upper case. This
means your message gets through faster.

2. You also only have to get 5 or 6 bits correct for the software to
decode a lower case letter, three less than for an upper case. For a
fixed bit error rate, this means the letter error rate will be lower
for lower case than for upper case.

Finally, there is the "email rule": capital letters are usually used
for emphasis (i.e., shouting), and are sometimes considered rude for
routine use.

Re: psk or PSK

Dave Kjellquist, WB5NHL
 

Duncan;
Thanks for the tips on psk operation. I learned just a little while back that lower case was faster and a little
less prone to errors. I never run over 5 watts with only indoor dipoles so I need all the help I can get. I have a
couple more tips:

1. Use a spectrum display rather than a waterfall. I can detect and communicate with much weaker signals.
Often, I get a comment that my signal can't be seen on the waterfall yet we will carry on a QSO. Perhaps not
armchair copy, but for errorless copy use IRC.

2. Kill the squelch. I use Hamscope on the "contest mode" only. Yes, I get random characters etc but this is the
same as listening to hiss as your tuning around in SSB or inband noise when your going after that weak one.
Squelch only causes the loss of the weak signals.

Just some thoughts from one of the little guys.

Dave, WB5NHL


psk or PSK

Duncan McMahon <zl3jt@...>
 

de Jungle Telegraph....Gidday!
I notice there is a penchant by some to type their psk text in the upper case(?)
I suppose I could call myself 'experienced' with this mode and I would like to tell
those that do this 'lazy' typing, that it is more prone to faults if this is psk
mode is done this way...
It takes a little bit longer for psk31 to send a CAPITAL LETTER, and if conditions
are marginal (QSB/QRN/QRM) then this method has a greater error rate. That is it
may be the difference between making it or not making it to the DX station.... Watch
carefully when you know a 'macro' is being sent to you....
To test my theory I typed the same macro in both upper and lower cases...it is a
surprising difference in speed!
You really don't need to try to keep ahead of the buffer...
;-)....Also when trying to 'break' into a QSO, just set a macro with only your callsign
once... then TX in the gap! If you send a long call you will probably be 'doubling'
with someone else and computers can't figure that out!
I do it from far, far away with a fair bit of success in the pile-ups! pssst! Don't
tell anyone!
happy pskin' in 2k2!

Hey dood, you DON'T hold their "070 certificates" in hand, and besides, I got
connections up "there". I submit the Steeler's win as proof that I indeed do
have connections. Maybe next year, and maybe the Easter rabbit will leave you
something other than "smart" pills. HI HI HI

Ok Jay, since you presented it to us like that, with absolutely no prejudice

Thanks for the QSO Steve.  It's kinda sparse out there, everyone must be on RTTY.  Hey, there's an idea...

Some of us are here. I took a few minutes out of Kids Day operation
to call you, Chas.

Kids made 8 QSOs so far, but company is here, so that will be it for
us.

PSKFest

N3DQU@...
 

Hey guys, the PSKFest is only two short weeks away would you believe!
Well, I did manage to get the event listed in QST and Worldradio, but
unfortunately I submitted the PSKFest Rules for publication before we decided
to delete the serial number as part of the contest exchange. The rules
posted on the 070 website are correct, but I suspect we will run across a
PSKer or two out there who didn't get the word about the change or don't
have access to the internet and will insist on a serial number from you. So
if you have a spare macro you aren't going to be using that weekend, suggest
you set it up to say something like "Contest rules were changed om, only RST
and SPC required for exchange." Hopefully, he will say thanks and let you go
without much of a fight hi! Jay

Just a reminder that we still need one more bonus station for the upcoming
TDW which is going to be held May 31. North America and Central Europe are
taken, so anyone in a geographical location other than those two areas who
would like to volunteer for this low paying but highly satisfying job, please
send me an email direct to n3dqu@aol.com...Tnx in advance...Jay.

Hi All PSK'ers
After hiding in the woodwork and monitoring this very good
reflector for about six months . I thought I'd jump in and ask a question .
I chase DX and am on the DX clusters quite frequently but I very
rarely see any PSK spots.Is there a reason for this or am I just
missing them?
73 de KF3AA Bob
Bob -

I agree that there are much fewer PSK spots than CW or SSB. I
tend to check occasionally on the DX Summit web site, and use
their Digital mode filter. That also includes SSTV and RTTY, but
maybe half the spots are PSK.

Re: So what do ya think?

Maybe John is not too often on the bands, he would have known that
FR8HA is every day on the bands and nearly every PSKer in his reach
must have worked him, the same applies to the FK8 stations, they are
very active, have worked several in several digi-modes - and that is
the great advantage of the PSK mode, you can have also a leisurely
chat with a rare dx, besides that I have worked 180 dx-entities in
PSK, started in December 2000, you can have both in PSK, chasing dx
and making new friends. 73's Erika/DL2AYL

My thoughts exactly (although I have yet to work an FK from here in
Pennsylvania).

Very well said, Erika.
