Kevin,
I went through that a couple years ago and discovered that the new power supply
I had just purchased for $25 had no filters on the AC line. Homebrew filters
helped a bit but a new Antec power supply (~ $30 after the rebate) solved the
problem. If you open the power supply case you may
Hi Kevin,
Truly a frustrating problem. RF interference is one of the most maddening
problems hams encounter. suggestions, some art, some science
Get on e-bay and get some very long VGA extension cords, a wireless
mouse/keyboard or buy some very long extensions and move the PC 6-8 feet,
The Switching Power Supply can cause interference, as you know. Other than
replacing the computer power supply with a higher quality one, or making sure
the power supply case has a good earth ground you might try putting ferrite
beads over the power lines coming out of the power supply, albeit
I would like to put in a few words in defense of the ARRL. I learned the code
prior to getting my novice license in 1955. At the time, that was just about
the only way one could learn, at least on a kid's salary.
These transmissions have been on forever, so I do question why this frequency
I was about to reply to the question of why the choice of frequency for
PSK31. I could not at the moment, but I see noone has addressed this point.
It happens that 3.579545 MHz (NTSC color burst) were aboundant and
rather cheap in the age of analog TV.
So, they have been used in some designs I
Hello kevin
Is your hamshack and computer on the same power outlet??
Try to use another outlet (maybe from next room with a long cable)
.
Has the noise gone or become lower ???
You can try to put a filter between the pc and the power outlet in the
wall

Can be built for a few bucks

They deserve it, IMHO. It turns out that W1AW has been looking for
alternative 80m cw frequencies for a while now. We just did not
know about it.
I do question why this frequency was used as the primary PSK31

In my opinion, the why isn't nearly as important as the fact that
we have a problem on the band nowadays. The fixed frequency psk
kits have been built and cannot easily be changed to another
frequency.

All,
Anyone care to chat on ALE-400? I'll be on 20 meters this evening.
Would anyone have a startup script txt file for a kam+ v 8.2 or give me some
pointers on how to write one that will work. I tried my hand at it but the
tnc doesn't respond to it. I would like to write an all mode script for the
RCwinpacket program. Thanks
Haven't done one in a long time. Last I did, I had the KAM in command mode and
waited for the prompt (cmd: ) to return to the screen between sending
commands out from my laptop - a Tandy/Radio Shack Model 102 using it's native
BASIC. Waiting for the prompt ensured that the previous command was
