Intermodulation 3rd Order Mix in Congested Tower Sites

I have a friend, I’ll call him Tuje (pronounced Tooge). He has decades of experience in commercial VHF/UHF radio communications. He wants to share his knowledge, but he also wants to remain anonymous. I offered to host his videos on my channel. So here is another video in an ongoing series of helpful videos, primarily relating to VHF communications, but certainly not limited to that topic.

Challenge extended by the Solder Smoke Podcast to create a homebrew 40 meter direct conversion receiver. The second stage (Doide Ring Double Balanced Mixer) of the radio is complete.

While on the hunt for a good signal generator for my ham radio workbench, I identified what I thought was going to be a good low-end unit. But the phase noise was terrible. In the end I found what I needed at a local hamfest.

This will be a great addition to me ham radio workbench and will come in handy with the homebrew direct conversion receiver project.

I went to the Oro Valley Amateur Radio Hamfest in Marana, AZ and found a great deal on an LCR meter.

I’ve made progress on the Solder Smoke Podcast homebrew 40 meter direct conversion receiver. I didn’t have an LCR meter for testing the transformers of the mixer. It really isn’t necessary to measure the inductance of the transformers. Just making sure there are 10 turns is good enough. But I wanted to be thorough and wanted to makes sure I have an LCR meter for future projects. So I picked one up at the hamfest.

Jonathan, KM4CFT, is best known for his CFT1 Transceiver, but he’s also come up with a few other great products at HamGadgets.com. The KM4CFT Iambic Paddle Kit is one of them — an easy-to-build, lightweight (just 1.3 oz) 3D-printed paddle that’s a blast to use.

It uses magnetic tension, has rubber strips on the bottom for grip, and works great either handheld or on a metal surface for POTA or SOTA. It’s available in eleven lever colors, and you can add an optional leg plate and strap for even more portability.
