Adds a lot to the Drakes  Time owned: 0 to 3 months
I bought the kit version of the A2 Digital Dial, and assembled it in about 3 hours or so. I haven't built a kit since the 60's, so some of the new technique required getting used to, (like getting 16 pins aligned in holes in the circuit boards, etc). If you are impatient and unenthusiastic about working with small parts, buy the assembled version.

The standard version comes with green and yellow numeric diplay figures, but I got my kit with red ones which looks neat with the Drake Blue Dial lighting.

Despite my limited kitbuilding skill in the new digital world, the unit checked out fine after I fixed a short in the data cable that connects the diplay board to the logic board.

The GREAT thing about this for Drake
R4A/B/C/owners is that you don't have to string a cable to "tap" into the signal frequency. All you need to do is plug the dial into the injection line that normally is used for transceiving between the tranmitters and receivers. You can use a radio shack "Y" phono connector for this. You do have to remove or clip R1 to get the right signal level from the 4 line.

I havent hooked it up yet to my Drake 2B or to the TR4, but I will.--the Dial is programmable in five different button-selected configurations, which allows you to make a switch with one touch when one of the bands tunes "backwards" like 20 meters on the TR4.

I think its a real hoot to have a digital dial. It has 100 hz resolution, and its VERY BRIGHT and plenty LARGE ENOUGH TO READ EASILY, while still being small enough to sit anywhere. Once you have it set up correctly, you no longer have to fiddle with the calibrator to align the dial or the knob skirt markings, ----you get "real lazy" and just look at the dial. It does not work exeactly like a modern transceiver's dial with the Drakes because it doesn't display properly until the preselecor is tuned into the right range. I find this is not objectionable, and the (lack of the proper)display alerts you that the preselector isn't in the right range.

Its powered from approximately 9 volts, so you can use it with a battery, or just use a Radio Shack wallwart as a power supply. My only wish is that it was in the Drake two tone grey colors---the case comes apart easily, and could be painted to match any scheme with very little effort.

The A2 will work with most any vintage reciever, but the Drake is a very easy hookup. If you buy the assembled version, you should be able to program it and have a digital readout in about 3 minutes (after finishing the instructions). Any equipment without a jack to tap the signal(as the R4 series has) will take a little longer.

If you want a useful new geegaw for your vintage rig, take a look at this one.
