| GENERAL |
| Type: | Citizen band transceiver |
| Frequency range: | 26.965-27.255 MHz (Sweden) |
| Channels / tuning steps: |
25 (1-24 + 11A)
According to swedish law at the time, SSB was only allowed on ch 24, and
therefore, switching this radio to LSB or USB automatically changed the
channel to 24.

| Additional info: |
The metallic lever switch on the far left is not a user modification.
It could actually activate an optional internal selcall transmit board.
The 2705AFS was mainly sold in Sweden, and possibly in some of
the other scandinavian countries.
