Chapter 1 The DSP-232
To the left of the Mode LCD display is ‘MAX’. This is the abbreviation for Maximum
Throughput. This will light when PACTOR data is being throughput as fast as the mode
allows. When in PACTOR, with the ‘P’ showing in the Mode area, you will be able to
distinguish the top line of the ‘P’ from this slash because the ‘MAX’ slash will blink.
Also on the left is ‘CMPS.’ This is the abbreviation for Compression. This will light when
data is compressed in PACTOR.
There are three abbreviations to the left of the STATUS portion of the window: CON, STA, and MULT.
CON is the abbreviation for CONnected, and glows while you’re connected to another
station while in packet.
STA is the abbreviation for STAtus, and glows while in packet when you’ve sent a packet
that hasn’t been acknowledged (
ack ed) by another station, yet.
MULT is the abbreviation for MULTiple. It glows constantly while you’re chatting
(connected) with more than one station at a given time while in packet. When the MULT
light blinks, it means that the DSP’s memory (32K standard, expandable to 256K) buffer is
full.
Note : the buffer can be filled with or without the computer connected to the controller since the DSP’s buffer
stores whatever it hears from the radio—not just the computer.
At the bottom of seven-segment LCD displays are two dots labeled: TX and MAIL.
TX stands for Transmit. This LCD dot will glow when you are transmitting data in any
mode.
Mail stands for Mailbox. This LCD dot will blink when you have mail waiting for you in
your mailbox.
Moving to the right is the tuning indicator. When you tune a signal, the LEDs behind the tune window will light a
certain way to tell you whether you’re tuned above or below the frequency of the signal you’re trying to receive.
The ‘Mark’ and ‘Space’ above the TUNE window denotes which way the Mark and Space tones are. With the
LEDs glowing, you’ll refer to the Mark and Space to see if the tones are above or below frequency.
Next is DCD, which means Data Carrier Detect. In HF, whenever your DSP hears anything—be it noise or someone
else’s signal—the LED will glow providing that the threshold is adjusted correctly. If it doesn’t glow, then it means
that the DSP can’t ‘hear’ any signals. In 1200 and 9600bps VHF packet, the light only glows if a valid packet signal
is heard.
