The unit is powered by connection to a USB power source, this can be a USB charger, USB battery, or the USB port on a PC or laptop. The K45 draws low current, about 140 mA, so a standard phone charger will work fine.
CW Reader Module (CWR) A very good CW reader function is built into the K45. Morse audio from a receiver is fed into the CWR which then detects, decodes, and displays it on the LCD display. There are four CWR settings available to the user to compensate for receiver audio level, noise, noise filtering, and signal thresholding.
The user first presses the ESC key, releases it, and then presses the desired command. ESC will be displayed on the status line to let the user know that the K45 is waiting for a command entry. ESC C – Configuration Mode System configuration is divided into fine menus, each with eight setting options.
TeraTerm and is free. The serial data settings are 19200 baud, 8 bit, with no parity. ESC K - Key mapping Menu The mapping of K45 keyboard keys to Morse characters can be customized. This feature is primarily used to customize mappings for international character support.
ESC-R – RTTY Setup Menu The K45 can be configured to operate in RTTY transmit mode. The format is fixed to Baudot FSK but there are many other options. A separate section on RTTY configuration and operation starts on Page 17.
The host application’s speed pot min and max settings determine what the end stops will be. Just like WKUSB, the K45 will appear as a serial com port to a host application. Here are the steps to follow to run K45 from a host application.
CTL-T - Tune This places the K45 in tune mode which forces a constant key down condition. Sidetone (if enabled) is turned on and the configured output is turned on as well. The user has the option of selecting 50% duty cycle by way of an entry in Configuration Menu #2.
This helps with: URRSTIS5NN. As the value is changed, it is flashed on the status line as CS+n or CS:-n where n is the adjustment setting. This feature has its limits, you will encounter operators who choose to use very large or small letter spacing which the K45 is not able to correct. K45 Programmable Messages There are 12 programmable messages per user, each message can be up to 120 characters long.
Fast Callsign Capture Feature The K45 can store a callsign as it is entered on the paddles. Press either ^C or the star key on the numeric keypad and CLL will be displayed on the status line. Enter the callsign on the paddles and after a pause of one wordspace, it will be stored in message slot F12.
Load Slot F10 with: CQ CQ CQ DE K1EL K1EL K1EL \JA After sending CQ CQ CQ DE K1EL K1EL K1EL we loop back to the beginning and send it again. This will repeat forever until either paddle or DEL key is pressed. When composing a message like this, be sure to put a space or delay at the end, otherwise the first letter will be sent after the last with no word space.
2000 Hz tone in HSCW mode. Alternatively, you can use the K45 key output to key an external tone generator. (note need to look at the outputs, PTT is dropping between chars) http://www.nitehawk.com/rasmit/...
VVV \K05 DE K1EL \W60 \J1 Three V's, a 5 second key down, DE K1EL, with a wait of 60 seconds will repeat until cancelled with DEL or paddle press. Note the placement of spaces around the key down to separate it from the adjacent text.
Load F3 with: \Q2\K05 EL FN43 \J3 Morse Practice Module The K45 has three practice modes that are very effective in helping a user improve their Morse skills. Practice Menu Press ESC followed by P to open the practice menu which is the starting point for all three practice modes.
Each trial starts with a single letter and progresses to a group of five letters by adding one letter at a time. If the user successfully echoes all five strings, the K45 will send AR and then start with a new group.
K45 CW Modem Manual After the initial exchange, The K45 will respond to BK if you don’t care to enter a full exchange on every go ‘round. To end a QSO early respond with either 73 or QRT and that will speed things along; TIME TO QRT or WILL SAY 73 works nicely.
K45 CW Modem Manual When the K45 is set to RTTY mode, it will transmit in Baudot only and Morse transmission is disabled. The transmit window acts the same way it does for Morse operation with the exception that Baudot strings must be delimited by square brackets.
OFF, and Space is signaled when the FSK output is ON. In reverse mode FSK if on during Mark. AUTO LF/CR On/Off When Auto CRLF is on, the K45 counts the printable characters in a line and after 45 characters, an automatic CR/LF sequence will be inserted after the next space. The character counter is reset after CR/LF.
Using a Straight Key with the K45 The K45 can be set up to work with a straight key. Wire the key to an 1/8” stereo plug as shown below. You must use a stereo connector and the ring must be left unconnected. Once the cable is ready, plug it into the K45 paddle input jack and then select Straight key mode in Configuration Menu #2:KeyrType.
The K45 provides a separate output that is enabled whenever CW transmission takes place. This output is called PTT which is a misnomer since it has nothing to do with Push to Talk. In most cases the K45 PTT output is used to key a linear amplifier or antenna switch. In those cases, it’s desirable to assert PTT in advance of keying (Lead In), hold throughout the keying interval, and then deassert it after keying is complete (Tail).

The K45 allows the length of the elements to be increased uniformly to compensate for this. The adjustments are made in one-millisecond steps. The maximum adjustment is 31 mSecs. Key compensation is very similar to Weighting in that any adjustment added to the dits and dahs is subtracted from the spacing, so the resulting speed is not changed.
6:WordSpac - Word Spacing Control Normally, the K45 spaces words by seven dit times. This can be adjusted in a range from 6 to 12 dit times. A tighter space speeds up exchanges which is helpful in a contest. Longer word space times aids in copying at very fast speeds where it provides extra space to separate words.
Ultimatic Dah mode. In straight key mode the K45 accepts input only on one set of contacts (see fig 14). The user enters dits and dahs manually. The K45 will decode straight key input just like it does for paddle input. This applies to normal sending and for Echo and QSO practice.
A challenge in this scheme is to determine when sending has stopped long enough to cause the transceiver to switch back to receive. If it has it’ll require a new first element correction on the next sequence. The K45 uses the PTT tail timer to determine this, set the tail timer to roughly match the transmit to receive changeover time of the transceiver and things will work fine.
SLEEP MODE message is visible in the display. All the onboard controllers go into low power mode. To wake the K45 up, simply turn the encoder. When Sleep is set to zero, the K45 will not go into low power mode.
K45. Move the cursor to this entry and simply press the encoder. The WinKeyer menu will be displayed and the K45 can then be connected to a host application on a PC. To exit WK host mode, press the encoder.
Power On/Off The K45 will power up as soon as it is plugged into a USB power source and will remain on. It can be put into a low power sleep mode by pressing the ESC-Y command or by holding the encoder button down for 3 seconds after the configuration menu appears.
Appendix A. Since all changes made in Configuration as stored in EEPROM, the next time you power up the K45, it will start up the way you like. Initially all message slots are cleared, but as you load messages, they are automatically saved in EEPROM.
Configuration Menu #2:Tune 50%. One last thing to mention before we move on is how to use a set of paddles with the K45. You can enter Morse on the paddles at any time. If the K45 is sending a message or something from the outgoing queue, it will be cancelled by the first paddle press and you can break right in.
CWR Noise Floor Threshold Adjustment Although low pass filtering on the K45 CWR will help decode a noisy signal, a very high level of background noise can degrade copy quality. Threshold adjustment can help with background noise by raising the signal threshold so that the CWR will ignore any signal below the threshold.
The app is divided into three groups, one for each controller. There are three different upgrade files, one for each controller. The K45 controller has the file type .K45, the WK3 IC has the file type .WK3 and the PSoC controller has the file type .PSC.
The K-45 is fully warranted to the original purchaser against defects in materials and workmanship for one year after purchase. This warranty does not cover damage caused by accident, improper care, or lightning damage. Please contact us before returning your K45 for repair and we will issue an RMA.
