FX-146 Quick Program Reference
Standard 2 Meter band repeater pairs and selected frequencies
Program as follows:
1. Install diodes at 16K, 8K, 4K and NO diodes at 32K, 2K ,1K positions.
2. PLUS install diodes at 512 through 1 positions as needed per this Quick
Reference Chart.
3. For repeater channels, add the proper repeater TX offset diode.
Simplex channels: add the 'SIMP' diode.
4. A '1' means to install a diode, '0' means NO diode.

programming explained in detail in the first pages of this Section.
In lieu of constructing diode bridges and wiring the channel selector switch,
you may elect to build your own switching system, using DIP, slide or toggle
switches. Do such projects only after your transceiver is finished and
working.
?
Channel Switch S2 may be installed at whatever
point in the procedure that is most convenient
for you. Its purpose is to apply +5V to the
desired diode bridge. Connect the desired
channel positions on the switch to
corresponding matrix channel rows using 2"
lengths of hookup wire.
?
For all channels installed at this point that you
intend for actual 2 Meter band communication,
remember to install a diode in the correct
position for Simplex, +RPT or -RPT. Install in only one position for any
given channel. Remember that the Receiver Frequency corresponds to
a repeater's output and that you are using +RPT or -RPT to match the
repeater's input frequency.
There is no need for diodes in the Simplex, +RPT or -RPT on any channel
intended only for listening. Also, be aware that omitting these diodes does
not completely disable transmitting capability.
Be VERY careful and use
common sense when monitoring outside the ham band.
RECEIVER ADJUSTMENT AND OPERATION
At this point, we assume that all preceding assembly steps have been
completed for stages "A" through "H" and that Stages "M" and "TX"
associated with the transmitter have NOT been done. A jumper wire is still in
place between "+8R" and "+8V." All IC's are installed except U4.
NOTE: If you already have done parts installation in stages M and TX, it
would be better to finish that work and follow the test and alignment
instructions provided in those sections. You can still test and use the
receiver section without damaging the transmit section if the directions in
Stage TX are followed exactly. In particular, do not install L10, R32, L9 or
