Input / Output VHF Antenna
Input VLF/LF/MF/HF Antenna Range 9 kHz ... 30 MHz (RX only)
For DUPLEX mode the input may stay open during transmission.
Input / Output VLF/LF/MF/HF Antenna Range 9 kHz ... 30 MHz (RX and TX)
Input / Output VLF/LF/MF/HF Antenna Range 9 kHz ... 30 MHz (RX and TX)
Output 2nd IF 10.7 MHz of SUB-RX. The output is tapped after the 2nd mixer. No AGC and no 10.7MHz
Xtal filter at that point. Thus bandwidths are determined by prefilters
Output 1st IF 40.7 MHz of SUB-RX. The output is tapped after the 1st mixer – thus being broadband when
preselector is disengaged
HF Antenna Signal for SUB-RX after passing internal antenna switch respectively TX/RX relay. Connected to
J7 (by default) or to input of external equipment (QRM-eliminator, ANT-switch panel etc.)
HF signal input for SUB-RX. Connected to J6 (by default) or to output of external equipment (QRM-
eliminator, ANT-switch panel etc.)
HF Antenna Signal for MAIN-RX after passing internal antenna switch respectively TX/RX relay. Connected to
J9 (by default) or to input of external equipment (QRM-eliminator, ANT-switch panel etc.)
HF signal input for MAIN-RX. Connected to J8 (by default) or to output of external equipment (QRM-
eliminator, ANT-switch panel etc.)
Output 1st IF 40.7 MHz of MAIN-RX. The output is tapped after the 1st mixer – thus being broadband when
preselector is disengaged
Output 2nd IF 10.7 MHz of MAIN-RX. The output is tapped after the 2nd mixer. No AGC and no 10.7MHz
Xtal filter at that point. Thus bandwidths are determined by prefilters.
