Third Party PCB Fabrication – My OSH Park Experience
My first experience with third party PCB fabrication was painless, reasonably priced and relatively fast. Oh, and they are much better than anything I could have done myself. Read more
Wideband Loop Base Amplifier Feeds Receiver
We complete the electronics requirements for our loop antenna design with a wideband loop base amplifier to match the transmission line to a receiver. Read more
Wideband Loop Transmission Line Choices
With a little ingenuity, you can select either coaxial or network cable for your wideband loop transmission line. Either will work, but I am going with twisted pair. Read more
Is It Time to Rename Amateur Radio?
Bob gave me a new Amateur Radio mug for Christmas. It falls short of trying to rename amateur radio, but does a great job of re-branding. Read more
Wideband Loop Antenna Head End – TIA In Action
Implementing a wideband loop antenna head end appears fairly simple with a transimpedance amplifier. But there are some tradeoffs between gain, stability and bandwidth you need to make. Read more
Wideband Loop Transimpedance Op Amp Selection
You can select candidates for a wideband loop transimpedance op amp by reading data sheets and simulating performance in LTSpice. Read more
LTSpice Digital Breadboard – Learning Accelerator
Download your free LTSpice digital breadboard and have some fun learning electronics. Test and understand your ideas before you actually build something. Read more
Wideband Loop Antenna Implementation Begins
Enough theory. It’s time to start the wideband loop antenna implementation using real parts and circuits. Read more
Remembering Ham Radio Magazines
Ham radio magazines have been part of my life for fifty years. The best of them all was actually called “Ham Radio Magazine”. Remember it? Read more
