No, but I've had the successor, a KDK2030. If it works at all, it should be a good rig for you for a little bit, 'til you can get something newer. Then maybe move it into the house as a base station. If it's like the 2030, it has a limited number of memories to store frequencies, (10, or 5, depending on how you set it up - it's hard to explain quickly. I can go into it in another post), probably does not include PL (which is becoming more and more common on repeaters today).
Remind me what the power connector looks like?
I myself wouldn't pay over $25.00 at a hamfest table, but free is a very good price for you!! & a good price for something to get you listening while you're studying for your test, or while you're researching newer rigs.
I suggest you find a ham who works for a local 2-way shop, or is retired from one and has some test equipment, and can test it for you for transmit power, frequency error & transmit deviation, and receive sensitivity, and ask for tutoring on how to replace the power cable.
