WSPR

Extremely easy to set up, just two audio cable plus the serial port. I have had reports using 100mW at over 200,000 Km per watt and using simple wire delta loop antenna. I have copied station from the UK who was using a small copper loop antenna, about 4 feet diameter.
I am also active on JT65hf and getting very good results. The K3 must be the simplest rig to set up for digital modes. Be prepared for frustration though. You will hear much more than you can work!!

It actually works fairly good.

You dont get confirmed contacts per say, but you can see your
propagation information via a map on the web. Its actaully fairly
amazing how far 0.5 watts can go. I also now know what another signal
looks like on the DM780 trace.

I played with it today and its another tool in the toolbox to see what
my antenna is capable of doing.

I find the JT65 very frustrating to get a qso in, as I can hear them but
they don't seem to hear me..

But then that is what patience is for with only 15 watts being used.

Re: WSPR

In the USA we can blame that on the replacement of the official FCC examination
system with the Volunteer Examiner program and the change of the ARRL from a
technical organization for technical people (Hams) to an organization pushing
easy license acquisition to aid manufacturers in selling more ham gear and thus
increasing the income of the ARRL.

Re: WSPR

Perhaps counter-intuitively, dropping the code requirement for ENTRY and
making CW voluntary, seems to be at the base of a CW RESURGENCE.

Since people CAN get pretty good copy with software, they are able to
participate in CW events. Rather than dumbing down the events, most enjoy
the increased range and better noise immunity of CW, and gradually learn to
copy better themselves as they are able. Logs in CW contests are UP rather
than down. In contests many operators routinely send from keyboard or
programs at rates they can copy, but these are speeds at which they can no
longer make their wrists/fingers move reliably (myself included). Way back,
I could send 45 WPM with a bug, and 50 plus with a keyer. Zero chance of
that now. I make mistakes above 25 wpm. I can TYPE as well as receive above
60 wpm.

Even those who just can't make CW fly are into the technical digital modes,
for just one example, note the rising numbers in RTTY contests.

I know that in PVRC, there are diehard SSB ops who are getting into the CW
tests because of the electronic assistance afforded in a transitional
learning period.

All is NOT lost.

73, Guy.

Re: WSPR

In reply to this post by KD8NNU

Don,
Do you run software to keep you PC clock in sync with UTC? If not, you won't
have much if any success making JT65A contacts. I use Dimension 4, and have set
it to sync my PC clock every 5 minutes. D4 is a free download and works well. Do
you use JT65HF software or the original WSJT software by K1JT for JT65A? I find
the JT65HF software by W6CQZ to be much easier to use. Is your transmitter
stable? Too much drift and you won't be copied.

Using wire antennas on HF and 3DB more power than you (I usually run 30 Watts
with my K3) in the past 2 months I have worked all 50 States and 60 countries
using JT65A. Once you figure it out, you should make plenty of contacts on this
neat mode.

Clock sync

Rich and all,

D4 does not state that it runs on Win7 or Vista. You might try the
freeware Atomic Clock Sync from
http://www.worldtimeserver.com/atomic-clock/ as an alternative. Version
3.0 runs on Win 2K, XP, Vista or Win7 (but not 64 bit). The older
version runs on earlier versions of Windows.

Re: Clock sync

Windows 7 has the ability to sync itself using "Internet Time" so you don't
need any additional software to do this.

I think XP has this capability also and likely Vista as well but it's been a
long time since I left XP for Win 7 and have not looked back.

All 32/64 bit versions of Windows have the ability to sync to "Internet
Time." However, they only sync once a week and do not retry in the
event of failure or if the computer is off, sleeping or hibernating
when it is time to sync. Changing the frequency of synchronization
requires registry editing and is not recommended of users who do not
understand the risks.

Well, yes, but you have to set it up properly.

Go to Control Panel > Administrative Tools and open Task Scheduler. Scroll
down to the bottom panel and you'll see a list of tasks. Double-click on
Synchronize Time.

This will bring up a new set of panels. Click on the Triggers tab. You'll
see something like "Daily" or "Weekly," which is the schedule on which your
clock is now synced. Highlight it, then click Properties at the right of the
page.

Another window will appear, also with a Triggers tab. Click on this tab and
you'll find an Edit button. Edit the trigger so that your clock sync repeats
indefinitely, every hour.

Some PCs have a stable clock, others do not. My desktop can stay synced for
several days within a second, but my laptop has to be re-synced every hour.
If you don't do this, you may find your clock is wildly erroneous even
though you think it's synced.

I did it that way too until I discovered that Windows has a tool for doing
it. See my previous post.

Re: Clock sync

In reply to this post by Joe Subich, W4TV-4

In addition to the automatic update - which is remarkably close with only a
weekly update - you can update it as often as you like.

If one is going to need better accuracy, you can manually sync the clock
anytime with a couple of mouse clicks to get to the "Update Now" button.

Again, this function is built in to Windows. You do not need any extra
software. You can leave that window open, and click "Update Now" as often as
you like while you need the additional accuracy.

No registry editing is needed to achieve accuracy on demand.

I use Meinberg's Windows implementation of NTP:
http://www.meinberg.de/english/sw/ntp.htm. It runs on Windows XP through
7, as well as NT and 2000.

NTP - Network Time Protocol - is an internet protocol for synchronizing
time. Almost all servers on the internet use it. It isn't at all hard to
set up. Windows 7 isn't optimal for time synchronization, and neither is
consumer internet, but you should be able to keep within 100 ms of
correct time. Linux or BSD over a well provisioned network easily does
better than 10 ms. Connect a GPS with Pulse per Second (PPS) output, and
you're in the low microseconds.

Re: Clock sync

In reply to this post by Tony Estep

Thanks to Tony for posting these instructions.

I once asked a Microsoft techie if there was a list of similar hidden
tools or command-line settings in a slightly different connection...His
response: "No."

Nice. Someone ought to collect these, together with Easter Eggs, Trap
Doors, etc...for WIN 7. Some of these OS's are so complex that even the
insiders don't know what's inside.

Re: Clock sync

In reply to this post by Jon Kåre Hellan

I was using NetTime up until last year. Works fine, is free, etc.

Another way to sync time works well if you use the K3EXREF and have a
GPS-DO running. Using Lady Heather (check out the icon), you can run
command line options at start up. One of the cmd line options is /ts,
which sets the Windoze clock to be the same time as the GPS receiver
(with some amount of software overhead, of course). This is good down
to a few mS, at least as observed here. And you can set the program
up to run at start-up time, plus sync periodically with the same cmd
line option. I have mine set to sync hourly, which is probably good
enough for us common folks...

That second approach isn't for everyone, obviously, but it works
reliably and performs consistently. OTOH, it's only good if you have
the hardware in place so it's not great for portable or
away-from-the-shack ops.

The Win32 program, "Lady Heather's Disciplined Oscillator Control
Program" can be found at www.ke5fx.com. This program is designed for
the Trimble Thunderbolt GPS-DO, which is readily available in
aftermarket and salvage over various web sites (eBay for example), and
its price ranges from $40 to $150 per unit. Low bidders seem to be
doing well - there are a lot of these retired E911 units out there.
