Kraco 2555 "Super Deluxe AM/SSB Base Station"

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


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.
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.

Receiver system: Single conversion superheterodyne (SSB)
IF: 10.695 MHz
Double conversion superheterodyne (AM)
1st IF: 10.695MHz
2nd IF:455 KHz
Sensitivity: AM: 1 uV (10 dB S/N)
SSB: 0.3 uV(10 dB S/N)
Selectivity: AM: 4 KHz (-5 dB), 10 KHz (-50 dB)
SSB: 2 KHz (-5 dB)
Image rejection:>50 dB
AF output power/speaker:3 W at 10% distortion / 8 ohm
External speaker connector:3.5 mm

RF output power: AM: 4 W
SSB: 12 W (PEP)
Modulation system: AM: High and low level class B amplitude modulation
SSB: Double balanced modulation
Max FM deviation:No FM
Spurious emissions:Less than -60 dB
Microphone impedance/connector:600 ohm / 4-pin (Metal locking ring connector)
Microphone input sensitivity:? mV
