- The uP's in the FT-23R and the FT-211R/H can be set for several
- frequency and memory mode combinations. These modes are contorlled
- by the jumpers (solder pads) marked 7,8 and 9 on the processor
- board of either radio. Here's a list of what can be done:
-
- JUMPER CONFIG DISPLAY MODE
- 7 8 9 NUMBER
-
- open open in 1 140 to 164 MHz, amateur mode
- open in in 2 140 to 160 MHZ, amateur mode
- in open in 3 144 to 148 MHz, amateur mode
- in in in 4 144 to 146 MHz, amateur mode
- open open open 5 220 to 550 MHz, commercial mode
- open in open 6 440 to 450 MHz, amateur mode
- in open in 7 50 to 300 MHz, commercial mode
- in in open 8 430 to 440 MHz, amateur mode
-
- Both of my radios (USA) were shipped from the factory in config #3.
- They can be converted to config #1 without re-tuning just by changing
- the jumpers. Tuning range can be further expanded by changing to
- jumper config #7. The FT-211 has separate VCO's for transmit and receive
- and will lock over about 38 MHz from approx. 130 to 180 MHz. The FT-23
- has only one VCO and the overlapping lock range (Xmt & Rcv) is about
- 25 MHz from approx. 135 to 175 MHz. Don't forget, if you adjust the
- VCO you must re-align every electronically tuned stage in the front
- end of the radio. The transmitters can be tuned for somewhat higher
- power output above 164 MHz but at a great power loss at 2m.
-
- The commercial memory mode will cause these functional changes:
-
- 1.When in the MR mode, the channel number will be displayed instead
- of frequency. You can toggle back to the original "amateur" mode
- display by pressing F<up-arrow>. Pressing F<down arrow> takes you
- back to commercial mode. However, when switching from D to MR, the
- display will always revert to the commercial mode.
-
- 2.The function of the Dot<Pri> button will be exactly reversed. That
- means now you can press just one button (Dot) to get into or out
- of the Primary function. The Pri funtion (in memory mode) will
- be indicated by a large "P" on the left side of the display.
