Ramsey Electronics FX Series - How to Activate an Auxiliary (Non-Standard) Offset

Here’s an example of the screen display for the program as written, showing
the results for an entry of “146865” and ready for the next frequency to be
entered as 6 digits:
For example: 146.52 MHz. = 146520. Enter here >>> ? 146865
The FX146 or FX220 N number for binary conversion is: 29373

HOW TO ACTIVATE AN AUXILIARY OFFSET:
1. Install NO diode in SIMP, -RPT or +RPT for the channel that gets a non-
standard offset.
2. Program the AUX matrix row for the desired offset, following our
published instructions.
3. Connect the channel row to the AUX matrix row by installing a diode as
shown below. The cathode end is soldered to the diode programming
bridge. In this example, Channel 3 uses the auxiliary offset:
16 K
32 K
+RPT
-RPT
