Re: Seeing K7HAK11 in waterfall and copying VA5BNC15 direct on APRS here in Alabama

where do you think K7HAK is located Bill?
I asked last night for anyones guess and no one had an answer. It may have gone right over me. after sundown so may have been even visible.

VA5BNC15 aprs signal

Bill Brown
 

Hi Bruce,

  I believe I have your signal spotted OK in the waterfall display along with all the other APRS signals on 144.390. Yours appears to have a large 300 to 500 msec TxD keydown before sending the APRS data...pretty distinctive and looks like a flagpole on top of the APRS data. Is that correct?

Photo size setting for attachments

Mark Conner N9XTN
 

Hank N1LTV made me aware of a limitation for the free tier for groups.io.  We have a max of 1 Gb of total storage for attachments, photos, and files.  At the moment we are using about 330 Mb.  

The default group setting was for unlimited image size for attachments.  However, allowing that will rapidly eat into our free tier storage if people post multi-megapixel images.  To postpone hitting the size limit, I've set the group to resize all photos to a max of 1024x1024 pixels.  With JPEG compression that should allow the list to contain a few thousand images before we hit the wall.

If you would like to exchange hi-res images, you can link to other sharing sites or share them one-on-one off list.

There does not appear to be a way to inhibit large file attachments, so please don't send large files to the list - use a link to another service if possible.  If we approach the limits for the group, we'll have to go back and purge messages with large attachments from the archive.

anyone have a guess where k7hak really is? looks like last up date was almost 30 min ago. it may pass very close to me.

Images from the NearSys flight in Oregon / Idaho

L. Paul Verhage KD4STH
 

I've attached one frame from the horizontal camera recording the burst at 98,331 feet. The rest of the images are near infrared images taken during the flight.

The near-infrared, healthy foliage shows up as bright white. Infrared light penetrates the atmosphere with very little scattering, therefore the images tend to be sharper than color images.

You can see the reservoir C.J. Strike (and the Bruneau Arm), Lake Lowell, and the Snake River. They all appear Inky black because they're reflecting near-infrared light from the sky overhead.

KK6UUQ7 in range of Denver area now

For those of you in EOSS territory, KK6UUQ-7 is in RF range of Denver.  It transmits on 144.390 MHz APRS every 2 minutes and then 10 seconds later on a clear channel of 144.340 MHz.

I have heard that cameras lacking an IR blocking filter will have a pink cast.

I think the RPi lens/image sensor system looks really awful, at least the one you got, since this pink haze is happening barely after leaving the ground.  Looks like it's maybe all due to the sensor, not the lens. Shouldn't have to rework this kind of simple picture; the same thing could happen on the ground at the beach.

Yeah, and i intentionally didn't do any post-editing on these photos so as to not mask the problem, etc. Normally I would touch them up a bit before posting.

I'm torn, as I think the optics are decent on this camera and (with processing) would be better than the old Canon that I have CHDK running on. Having the Pi really opens up a whole new world when I'm working with a school to let the kids do some programming on it. But if I can't get a steady supply of these things then I don't know if it's worth pursuing this option. It was nice because I had maybe $80 is the whole solution and could easily reduce that by going with the Pi Zero for instance.

Zack,

It's certainly apparent what you're talking about and it would be disappointing to anyone.

Using the commonplace meaning of chromatic aberration (of two distinct types), what you have is not chromatic aberration.  I'll get a better look tonight but some of the images look as if they're suffering from big differences in brightness, the effect of which is similar superficially to "lens flare" but not the same.

Regarding "lens distortions," this phrase is usually used to refer only to departures from rectilinearity, so it's a geometric or topological deficiency.
