Reviews Summary for N0XAS Universal Keying Adapter
N0XAS Universal Keying Adapter Reviews: 13 Average rating: 4.9/5 MSRP: $10.00
Description: Interface your electronic keyer, computer, bug and/or straight key to your cathode or grid-block transmitter, or connect your solid-state transceiver to your tube amp. Ultra-simple kit has inputs for a key or keyer plus a computer input, and can key up to 400V AC or DC at up to 250 mA with its optically isolated solid state relay. By popular request the updated, new UKA-2 kit includes RCA phono jacks, provision for external power from nearly any AC or DC source, an LED to indicate activity, and more. Still great for interfacing keys to grid-block or cathode keyed rigs, computer to PTT, you name it.
Product is in production.

Ideal for keying old rigs or amps  Time owned: 6 to 12 months
Couldn't be easier to assemble. Functions as a solid-state relay and can switch up to 400 volts, ac or dc, 140 ma.

I'm using one to key the relay in an old SB-200.

There's a new model (UKA-2) now that's a little fancier, designed to work from 12 (actually 3-15) volts rather than two AAA cells, has connectors attached, and an LED that shows when you're in key-down mode. Think I'll get one of those just to have it on hand. Even if you're keying a 12 volt relay, it might be wise to have one of these in the circuit just to protect your expensive gear from possible transients.

Great Cheap Solution  Time owned: 0 to 3 months
For 10$ and a little time with your soldering iron, you will have a functioning solid state amplifier control switch that will save the cheesy relays that the manufacturer's install into the transceivers these days. Installed mine between my ICOM IC-746 and my Heathkit SB-1000 linear. Worked first time and everytime. If you want to get fancy you can mount it in an exclosure but mine sits right out there in all it's naked glory. A worthwhile project to practice your soldering on. Glad I discovered the write up here on eham and visited the website. The instructions are clear and thorough. They also cover the operation of the circuit.

Cheap solution!  Time owned: 0 to 3 months
This little gadget will enable you to key an old transmitter or switch an old amplifier requiring higher voltage or current than modern rigs can handle. It is all solid-state, so no noisy relay is involved, and it runs on a pair of AAA cells, so no external power connection is necessary. It fits easily in an Altoids tin. Took me 5 minutes to assemble and get working (honest!). Now my FT-1000 switches my ancient 30L-1 amp easily and silently. And for cheap, too.
