I really like it!  Time owned: 0 to 3 months
I bought the unit at Dayton 2003, based on the reviews on The kit goes together nicely. Just like a Heathkit in terms of documentation, ease of soldering and assembly. Took about 4 hours, but I double and triple check everything as I proceed. It's complete -- just supply the usual hand tools and solder. Worked the first time!

There are four buttons on the top for regular memory keying. One of the neat features is that you can embed information such as a contest contact serial number within the memory message string. That means, when you program a message which includes /N and press the memory button to send, it will send the contest exchange and automatically increment the serial number.

In case the other station has a problem receiving, you can embed another string /D to decrement the serial number, send it, and increment it. Program that into another memory, and you can send a "repeat" message that includes the same serial number.

On a recent CW contest, I used the hunt-and-pounce method of operating. I programmed the #1 button with my callsign (I send left handed), #3 with the repeat message, and #4 with the "TU 5nn /N" message as a response to the the other station. Press #1 to get his attention, press #4 to make the exchange, and #3 in case he didn't get it. I can work the entire contest by pressing three buttons!

You program or inquire the unit by pressing multiple buttons at the same time. The unit goes into command mode, responds with a letter, and waits for you to key a short CW command. You can change the format of the contest serial number, keying method (Curtis Mode A or B, etc), weighting, normal or reverse keying, initialize the contest serial number, etc.

You also use this method to program the memory string. It took a little while to get used to the editing, but I must admit, it's quite ingenious. Once you start keying, it records into the memory. If you pause a while, it stops recording. If you make a mistake and send multiple dits, it erases the mistaken word you were entering, repeats the last "good" word in CW, then waits for you to complete the message string. I was confused about the keyer repeating the last good word, until I figured out what it was doing.

The speed knob on the front is very convenient for operating, as you can speed up or slow down the sending instantly to match your conditions. The volume control is a pot accessible through a hole in the bottom of the case.

All in all, a very worthy keyer and a very fun project. It really adds fun to CW!
