DSP filtering. This stage provides enough
amplification to maintain the receiver
sensitivity despite unavoidable filter losses.
The amplified and band-limited signal feeds
the IF converter board (A5) via cable 16.

A5 provides conversion to the 2

nd

IF (455

kHz), amplification, filtering, and conversion
to the 3

rd

IF for processing in the A7 logic

board. Cable 18 carries the 14 kHz third IF
to the DSP in A7.

After digital signal processing in A7, the
recovered audio feeds the main receiver
audio input on the audio board, where it is
mixed with sub audio or directed to the
headphone amp or the main speaker amp.
The main audio travels through cable 48 to
the connector board and is sent to external
speaker jack or speaker.

The synthesizer board (A10) supplies 1

st

local oscillator signal to A3 via cable 12, and
2

nd

LO to A5 via cable 19.

Signal Path – Subreceiver

For the subreceiver, the signal path starts at
an antenna jack selected by the I/O board
(A0) and proceeds to A6, the subreceiver
board. This board comprises the entire
analog circuitry of the subreceiver,
accomplishing conversion of HF signals
successively to 45 MHz, 450 kHz, and 14
kHz intermediate frequencies. 3

rd

IF signal

travels to the DSP via cable 20 and feeds
sub RX audio input on the audio board. The
audio signal also reaches the EXT SPKR
and AUX I/O jacks via A11 and A12. From
A12 it runs through wire cable 36 to the
internal speaker.

The synthesizer board (A10) supplies a 2

nd

local oscillator signal and a frequency
reference for the subreceiver’s 1

st

local

oscillator to A6. Cables 23 and 21 carry
these signals.

Signal Path – Transmitter

The TX signal path has the MIC and CW
(key/keyer) jacks on A8 as sources. Other
sources are the KEY and AUX I/O jacks on
A12. The audio signals from MIC travels
through cable 47 to the audio board. The
signal is amplified and passed to the
logic/DSP board (A7) through cable 25. The

AUX I/O travels via cable 24. Keying lines
get to A7 via A11.

From the DSP, cable 17 carries keyed or
modulated 3

rd

IF to A5. The 9 MHz output

from the IFCNV feeds A3 via cable 13. The
resulting HF signal can go to the XVRTR RF
jack on the I/O board through cable 3, or to
the PA (A2) via cable 8.

From A2 the path to the LPF board is via
cable 7. Cable 27 brings the high level
amateur band HF to AO, the I/O board. On
the I/O board, the signal is routed to the
selected ANT1 or ANT2 RF output
connector.

If it is installed, the optional internal
automatic antenna tuner (A14) is connected
in the ANT1 path only. Cable 26 provides
the A14 input path, and cable 27 is the
output path. If the transceiver has no A14,
cable 28 replaces the autotuner.
