[Today’s run: 3.5 miles]

I came to the conclusion that the antenna was not the complete picture.
I think I have two other things also going on. First is that the control voltage is toward the upper range. Second is that the oscillator got into a fugue state, like it did when I first built this thing.

I’ve twiddled the gross-frequency control and I think I have the oscillator working correctly again. Now I’m trying to get it adjusted so that I can shift the control voltage back to the middle of the range.

I’m having some trouble remembering how to interact with the thing using the old laptop I employed on the project in 2012 (?). But I can always just adjust it and wait the many-days necessary for it to self align with my adjustment. Eventually I’ll get it back to where I want it.

In other news: We’ve been finding bumps growing on our dog. We had a couple of them removed for testing and today the results came in that they are malignant. The vet told us he probably doesn’t have much longer with us. He had been wearing a cone to keep him from messing with his bandage where a bump was removed. I decided we’d had enough of that. I’m home most of the time and can keep him from doing any serious damage. I took the cone off and he did fine. This evening we went to Wendy’s for dinner and I got him a Jr. Baconator.

    Paxton the smiling dog. I too am sorry about his prognosis. I’m glad you got him a fun sandwich to enjoy for dinner.

    Sorry to learn this about Paxton. I always enjoy seeing his adventures on Facebook.
