SO2R RX Loop Antenna

Todays work included installation of the SO2R RX Loop Antenna and associated devices. The W6LVP relay will provide switching for the SO2R RX Loop Antenna. I’ll also install some front end protection.

Here are some of the items on the agenda:

SO2R RX Loop Antenna
The wiring is nearly complete.

The SPE Expert 1K-FA amplifier allows connection of two transceivers, four antennas, and, an SO2R RX antenna. When the OP is transmitting on radio#1, radio #2 is connected to the SO2R RX antenna. This enables the operator to listen on radio #2 while working the latest DX on radio #1, and vice versa.

SO2R RX Loop Antenna for low noise

Operating in SO2R mode presents the possibility of overloading or damaging the sensitive RX front ends of the two connected transceivers. The 1K-FA manual warns of this possibility and cautions the user about antenna separation and it is suggested (and makes the most sense) that receiver front end protection devices be considered.

The Flex transceivers have built-in RX protection, but adding an RX front end protection circuit offers one more level of protection.

The low noise RX Loop Antenna is hereby considered a major station improvement!
