What a Nice Hammy Christmas

Filed under: ham radio — Cranky Sysadmin @ 10:50 pm

My wife had asked me not to buy a ham radio before Christmas. It turns out that it was worth the wait. She got me a Yaesu FT-450D. I am having a ton of fun with it.

When in Doubt, Put in a Load Resistor

Filed under: Electronics,ham radio — Cranky Sysadmin @ 8:23 pm

I am experimenting with various oscillators and having a lot of fun. It’s the first time that I am having a lot of success putting together analog circuits that work. I am also having my brain-farts. I am working on a Vackar VFO. It turns out to be a stable VFO with a nice clean sine wave, but that has nothing to do with my brain-fart.

A nifty homebrew LC meter

Filed under: Electronics — Cranky Sysadmin @ 8:57 pm

I spent the day putting together a less unattractive LC meter then the one I had on a breadboard. As I said in the last post, the design is from Kerry D Wong. As an exercise, I made an attempt at getting the parts strictly from the local radio shack.

Before I Build a Tranceiver…

I picked up a copy of the ARRL Handbook for Radio Communications. I bought and fixed a nice Fluke 1935A frequency counter, and I just built an LC meter from mostly parts at radio shack.

Now that I’m a Ham…

Filed under: ham radio — Cranky Sysadmin @ 9:07 pm

One of the things I want to do, now that I have an amateur radio license, is build a transceiver. I’m probably going to settle on the Bitx 20 since I can hold the whole design in my head. I’ve actually built the VFO on a breadboard as a learning exercise.
