PK-232 MBX – OPERATING MANUAL RADIO INSTALLATION
4/91 3-5 29
This completes the minimum necessary connections for transmit and receive operation
with the PK-232. If you are interested in using the PK-232 to transmit Morse code (CW) or
transmit RTTY using FSK inputs on your HF transceiver, the following three sections
(3.3.6, 3.3.7 and 3.3.8) should be read.
If you will not be using any of the connections described in the following sections, then
skip ahead to the Final Adjustment section 3.4 where you will set levels and prepare to go
"On the Air".
3.3.6 Wiring Your HF Transceiver for Direct CW Keying
The PK-232 can directly key CW with HF and VHF multi-mode transceivers. This requires
that a cable be wired from the CW KEY OUT jack on the PK-232's rear panel to your CW
keying input of your transceiver. Refer to the following instructions and Figure 3-3 below
to wire the PK-232 side of the cable.
Figure 3-3 Direct CW Keying Cable diagram
1. Locate an RCA connector from the PK-232's accessory bag.
2. Locate some shielded audio cable from Radio Shack or other cable house and solder
the RCA connector to the cable as shown above.
3. Locate the connector for the CW keying input to your transceiver. These are often
supplied in your transceiver's accessory kit.
4. Wire the transceiver connector as per the instructions in your transceiver's manual
for a "Straight key".
Consult your radio's instruction manual to determine if your radio uses negative (Grid
Block) or positive keying polarity. Connect the shielded cable you just wired from the PK-
232's positive (J9) or negative (J10) keying jacks to your radio's CW key input connector.
See the Specifications on page 1-3 for maximum limits.
3.3.7
Connections for Direct FSK Operation on RTTY
Some HF SSB radios provide direct FSK (Frequency-Shift Keying) for RTTY operation. FSK
operation can be an advantage when using RTTY and AMTOR modes and can sometimes
help in HF packet operation. FSK operation may be especially helpful if your transceiver
can switch in extra filters. Be cautious of a narrow filter as narrow filters can limit your da-
ta rate. Direct FSK is not always recommended for data speeds in excess of 110 bauds.
Consult your transceiver's manual regarding direct FSK operation for further recommenda-
tions.
To install and operate your PK-232 and radio in the FSK mode:
1. Connect a shielded cable from the PK-232's J7 (DIN) receptacle, pins 1 or 4, to the
radio's FSK input.
