The Europa B from Solid State Modules is a linear transmit and receive converter from 28-30 MHz to 144-146 MHz or 50-52 MHz and is suitable for use with either a transceiver or separate receiver-transmitter.
A crystal switch and extra crystal can be installed to extend the frequency coverage. Although designed primarily for SSB operation, the Europa B will receive and transmit any mode which the HF equipment is capable, SSB, AM, FM, FSK, or CW.
The receiver converter is broad-banded to cover the entire VHF band without any tuning, It uses dual-gate MOSFETs for optimum sensitivity, gain and low cross-mod. The noise figure is 2 dB; converter gain is 30 dB. The transmit converter uses tubes to provide high power, good linearity and high rejection of spurious signals.
Power input is 200 watts (50% efficiency, minimum), drive requirement, 200 mW.
