At the regular SVARC club Zoom meeting on Thursday, September 17, 2020, at 7:30 pm, club member Roger Steyaert K7RXV made a presentation on the topic of network analyzers. These can be used to measure antenna or coax parameters such as SWR, impedance, and loss. They can also be used to characterize and tune filters. A network analyzer is a very useful tool to have if you are building and tuning homemade antennas, filters, or other RF circuits.

All: Mark, K4ED, has let me know that this rig has been sold and found a new home as of some time in early September.
Gently used Yaesu FT-450AT (the version including the automatic antenna tuner) including the original box, manual, etc. Radio is original, not modified, and never used mobile.

For more details, contact firstname.lastname@example.org.

Challenging times call for creative solutions, and here’s a cool one: an ARRL-sanctioned virtual amateur radio expo with renowned speakers, exhibitors, and special conference rooms built on a virtual reality platform.
