+Precisely Matching Frequencies of RX-366 and Main Orion Receiver
Set AUDIO Left and Right to "BOTH". Set both receivers for same mode (CW or SSB), BW, zero PBT, zero RIT, and both receivers to antenna 1. Set both receivers to VFO A. Set the audio level for each receiver to the same loudness. Tune in a steady carrier. There should be a beat note.
Select “SUB RX” (button number 55 as shown in owners manual), hold down the “RIT” (button number 48 as shown in owners manual). By turning the main tuning knob SLIGHTLY you will change the frequency of an oscillator in the sub receiver by .1Hz per step. You should be able to zero the difference between the two receivers. This should hold for all modes and bands within ½ Hz.
