*** TO BUY WITH CONFIDENCE, YOU ARE GETTING PAYPAL PROTECTION ! ***

25 USD SHIPPED ONLY !!

This kit includes the assembled and tested CW Keyer PCB and some other parts you can see on the pics. Also I am including the circuit diagram, diagram of connections and CLEAR ENGLISH INSTRUCTION how to use this CW Keyer and using the CW Key store your text messages in keyer's memory banks.

This IAMBIC CW Memory Keyer has two operational modes:

1. CW IAMBIC KEY "A" MODE
2. CW BEACON MODE

YOU CAN SWITCH OPERATIONAL MODES CHANGING JUMPER JMP1 POSITION OR USE THE SWITCH INCLUDED IN THIS KIT SOLDERING IT TO THE JUMPER CONTACTS.

CW IAMBIC KEY "A" MODE
In this CW IAMBIC KEY "A" MODE  you can use this Keyer just everyday working in the air. Also it allows you to send the AUTO CQ call or/and stored in its Memory Bank THREE message.

To activate AUTO CQ function push momentarily the SELECT knob. The Keyer would send this message:

CQ CQ DE (call sign) (call sign) K - then 5 sec pause and it repeats again until you click the DOT of your key or push the RESET knob mometarily.

To activate Sending Message function push and hold for more than 1 sec the SELECT knob. The Keyer would send ONCE a message that was stored in the Memory Bank THREE. You can stop it by clicking the DOT or push the RESET knob mometarily.

CW BEACON MODE
The CW BEACON MODE is usable in HF or VHF Beacons. In this mode the Keyer is repeatedly sending the standard beacon message:

"Call sign" BEACON QRA "QRA LOC" then 25 sec long Beep then 5 sec pause and it repeats again and again.

Even if you switch the power supply OFF and then in a time ON again the Keyer would start sending the beacon message while it is set in the CW Beacon Mode.

This Keyer works fine within 5 to 15V DC voltage.

To get this KIT worked you should solder its connectors and some other parts to the pins on its PCB. I am including the circuit and diagramm of the connection. It is really very simple. Only thing you have to do is to find a suitable enclosure of your choice and mount the PCB and connectors there. Or you can place this Keyer PCB inside your radio or VHF & HF Beacon.

1. Pushing Knobs S1 and S2 (SELECT and RESET knobs)
2. Power supply panel connector (power jack fits there)
3. Power jack (to solder the power cord there)
