April Snow

What happened to spring? Here we are in mid-April with its fickle weather. Does make for pretty pictures, though. This one was taken from inside our dining room.

I took the photo with my ancient Pentax K100D and Tamron zoom. Three photos were combined in Photomatix to give higher dynamic range.

My First Audiobook is Now Online

I just completed producing the audio files for this book. It's available now on Audible. Click on the image to go to the Audible website where you can listen to a free five minute sample.

For every audiobook people listen to, someone has to create the audio recording, right? Amazon bought Audible, an audiobook company, and has automated much of this via the Amazon Creative Exchange, or ACX. I signed up for ACX and auditioned to “produce” (meaning create the audio files) a book called Santa Cruz Island, a History of Conflict and Diversity.

It took an unbelievable amount of work, including a bunch of stuff that had to be thrown out and re-read. That’s okay, since this was my first project. I’ve even created a lessons-learned list. I discovered things about my voice that I didn’t know, such as that it changes pitch slightly but noticeably during the day.

Anyway, you can see the Audible page for the book by clicking here. There’s a five minute free sample of the book.

Rubber Stamp Helps Create Log From Notebooks

More than 25 years ago, I gave up on pre-printed logbooks and started using ordinary (and much less expensive) spiral-bound notebooks. To keep all the pertinent information in one place, I use a rubber stamp that I had specially made at a local stationery store.

Here's the rubber stamp I had made at a local stationery store, sitting on an American 3" x 5" card for size comparison.

So, before each QSO, I stamp this in my notebook. Then I can collect the information I need for QSLing in one place. This is what the stamp impression looks like:
Logbook stamp impression. The stamp is over 25 years old, so it's gotten a bit fuzzy over the years, but still serves its purpose well.

Note that the info about the QSO isn’t complete—it’s missing the date. So I write the UTC date in the left margin. Here’s an example from a QSO I had last night:

You can see the UTC date in the left margin. I can then record anything I want about the QSO underneath, such as the operator’s name, location, station information, and anything else. I can use as much or as little space as I want. Sometimes, when I’m copying CW, I just copy right into the notebook, and then everything about the QSO is in one place. Then I just stamp again for the next QSO. Nifty, huh?
