[Elecraft] Elecraft CW Net Announcement

2023-12-09 Thread kevin 

Good Evening,

   There were brief pauses in the rain this week.  Sometimes the breaks 
were sunny.  Other times there was snow.  Snow line keeps moving up and 
down past me so any accumulation is temporary.


   The sun has a few large, active sunspot groups.  There are no 
predicted CMEs.  Signals should be fairly good, with some QSB and a 
steady hiss.  It will be dark here when the forty meter net begins.  
Conditions should be good then.  Let's see.


Please join us on (or near):

14050 kHz at 2300z Sunday  (3 PM PST Sunday)
 7047 kHz at 0100z Monday  (5 PM PST Sunday)



73,
  Kevin.  KD5ONS





-





-- we can not hallow this ground.  The brave men, living and dead, who 
struggled here, have consecrated it, far above our poor power to add or 
detract.  The world will little note, nor long remember what we say 
here, but it can never forget what they did here.

Re: [Elecraft] KAT500 Sleep current?

2023-12-09 Thread G4GNX 
Interesting to note that there is no “Idle” button in your image. I guess 
that’s elsewhere in the utility.

I would assume that as they’ve used the word “Power” in the utility, I’d expect 
it to be the same as the power button on the front panel of the KAT500. From 
what you’re saying, it certainly seems to act that way.

My setup has the KAT500 power up when the shack PSU is turned on, but I always 
hold the power button on the KAT500 when I turn the radio/s off and of course 
all of the LEDs go off.

MY setup is all hard wired so I can’t easily get a meter inline to check 
current consumption when the KAT500 is ‘off’. I don’t have consumption issues, 
as all of my power is turned off when I leave the shack.

Sorry I can’t be of much help.

[Elecraft] OT: The 4-track mind

2023-12-09 Thread Wayne Burdick 
Occasionally I stumble on something too incredible to not share, immediately, 
with everyone. In this case I'm inclined to not even apologize for using the 
bandwidth. At least not in advance.

Anyone intrigued by human perception of sound, especially musicians and 
ambidextrous CW ops, will find this fascinating, baffling, and perhaps 
enlightening in some way I can't predict:

I think it does more than shutdown the oscillator. It seems to turn off all 
leds and return the unit the bypass mode. It looks really shutdown. I am 
referring to this checkbox "power" on the top right.

Subject: Re: [Elecraft] KAT500 Sleep current?

From the KAT500 manual:

"Idle Sleep
In some installations a 28004.5 MHz signal may be heard from an oscillator in 
the KAT500. If this is an issue, you can shut it down when it is not needed. 
Click on Idle Sleep to put a check in the radio button. The oscillator will 
stop running shortly after the last key press or the last data communication 
with other equipment and restart automatically when needed.”

From this, one might presume that’s all the ’sleep’ does - turn off the 
oscillator and the rest of the circuitry remains live. The spec also says: 
Supply Current 1.0 A max (200mA typical). I’d assume that the KAT500 would 
continue to draw around 200mA whilst in standby and turning off the oscillator 
(sleep) would make very little difference.

[Elecraft] KAT500 Sleep current?

2023-12-09 Thread W2HX 
When I use the KAT Utility to power down the KAT500, anyone know how much 
current it consumes in this sleeping mode? I ask because I was surprised that I 
had a dead battery this morning after a week or so of non-use (battery is a 
rechargeable Lipo so no problem) but I was wondering how "asleep" it actually 
is.
