A picture of Kraco 2555 ''Super Deluxe AM/SSB Base Station''

SPECIFICATIONS

GENERAL
Type:Citizen band transceiver
Frequency range:26.965-27.255 MHz
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.
Mode:AM/SSB
Frequency control:PLL (PLL02A)
Frequency stability:0.003%
Power supply:Mains: 220 VAC (Fixed power cord)
Current drain/power consumption:RX: ? W
TX: Max 75 W
Antenna impedance/connector:50 ohm / Two SO-239 (Switchable)
Dimensions (W*H*D):405*150*300 mm (15.95*5.9*11.81"), without rack mounting handles
Weight:8.5 Kg (18.74 lb)
Other features:ANL/NB. PA. SWR meter.
