Re: [Elecraft] Poor band conditions? Try the SCAN function

[Drew AF2Z]

From time to time I set up a wireless intercom/camera ("baby cam") in 
front of the K3 while scanning. Then I can monitor the action remotely 
down in the workshop or while working out, fixing dinner, etc. (Now, if 
I only had a wireless remote control to fully operate the K3's receiver...)

At times like this, the SCAN function available on most Elecraft transceivers 
can help you find signals you might otherwise miss. SCAN does the work for you 
while you check your email, play chess, re-read The Lord of the Rings, shave, 
etc.

When a signal pops up, scanning stops, and the receiver unmutes briefly so you can 
consider the signal's worthiness. As you'll discover, bands that were "dead" 
may not be, in reality. My favorite band for this sort of thing is 15 meters, in the late 
afternoon. A minute or two after starting a scan, you may hear DX appear from out of 
nowhere.

For specific instructions for your rig, check the table of contents in the 
owner's manual.

Here a few general tips:

- use a narrow filter passband when possible, especially if the band is noisy

- the tuning RATE in effect when scan starts determines how long it takes
   to scan the selected segment; finer-tuning slows things down, and may result
   in detection of weaker signals

- if the band is noisy (QRN), the SCAN function may unmute too frequently; try
   using the noise blanker

I also have often thought that a user settable pause time would be most 
useful. I usually scan when I'm doing other things around the shack (or 
in another room), not sitting right in front of the rig watching the scan.

about 30 secs or so. But which length of pause it uses on what type of
signal it stops on seems a bit random. Sometimes it'll open up and pause on
an actual CW signal for the short pause, but then the long 30 sec. pause on
a continuous noise source. And sometimes the reverse.

Not a complaint, though I wonder if there's a way to specify a pause time
somewhere. forgive me if that's in the manual somewhere already...

and up today, tho lots of stateside sigs on 30 and 40M

I'll have a look at this when I get a chance.

Re: [Elecraft] Poor band conditions? Try the SCAN function

[Gary Smith]

The bands have indeed been in lousy shape lately; There was a SP RTTY 
contest on this weekend and I made two QSOs on 21 MHz, zero on 28 MHz 
and around 130 of them on 20M & 40M. Only three Q's on 80M. The bands 
were just lousy.

While the bands just aren't good at all right now, thanks for the 
reminder of that excellent "search" feature. Thanks to the beauty of 
the P3, I use that to find where there's "life" on the bands but sans 
P3, the search is golden.

[Elecraft] Poor band conditions? Try the SCAN function

[Wayne Burdick]

Here in Northern California, at least at my QTH, the bands seem to be in very 
poor shape. (It doesn't help that my OCF dipole has one leg on the ground due 
to high winds.)

At times like this, the SCAN function available on most Elecraft transceivers 
can help you find signals you might otherwise miss. SCAN does the work for you 
while you check your email, play chess, re-read The Lord of the Rings, shave, 
etc. 

When a signal pops up, scanning stops, and the receiver unmutes briefly so you 
can consider the signal's worthiness. As you'll discover, bands that were 
"dead" may not be, in reality. My favorite band for this sort of thing is 15 
meters, in the late afternoon. A minute or two after starting a scan, you may 
hear DX appear from out of nowhere.

For specific instructions for your rig, check the table of contents in the 
owner's manual. 

Here a few general tips:

- use a narrow filter passband when possible, especially if the band is noisy

- the tuning RATE in effect when scan starts determines how long it takes
  to scan the selected segment; finer-tuning slows things down, and may result
  in detection of weaker signals
