• Notes
• The Rider Chanalyst for Signal Tracing features five separate channels, permiting the isolation of intermittent troubles. The RF-IF channel is a 3-stage tuned RF amplifier (TRF for 95 through 1700 kHz). A single stage TRF covering from 600 kHz through 18 MHz is for checking a receiver's local oscillator. The fifth "channel" is a center-zeroing 11 MegOhms-per-volt vacuum tube voltmeter.
