A demo of the radio. Sloppily tuned. I was trying to tune everything and nothing just to show what it is capable of.
The antenna is 100' of hook-up wire going up to the attic. An outside antenna would work better.

In conclusion, the Ozark Patrol is a great little regen kit that performs well with headphones or an added amplifier for speaker operation.

A few tips

longwire antenna
   Tip 1: The instructions say to connect an antenna to the radio. What kind of antenna? It's just a piece of wire! How long should it be? 65 feet is a good length for reasons we won't go into here. If this isn't practical, just try to get as much wire in the air as possible, preferably outside.

Grounded plug

   Tip 2: This radio needs an earth ground to work properly. Without the earth ground the signals are weak. If you can't easily connect to a ground you can pick one up using an old computer or printer cord. Cut the blades off with a hacksaw, leaving the ground prong. Make sure you have the correct color wire, and cut off the other two wires. Now just plug it in, and you have a ground wire.

   Tip 3: You've just finished the radio, you've turned it on and you hear... nothing. Or, you hear one station, and that's it. Look out the window. Is the sun up? Some of the shortwave bands are basically stone dead at certain times of the day. Try again around 7PM.

   Tip 4: You tune in a station, move your hands off the knobs and, "Vweerp!" the station vanishes. You put your hands near the radio and "Vwoop!", it comes back. This is caused by "hand capacitance." Basically, the radio is emanating an electrical field and your hands are disturbing it. I was able to cure this by putting a small value capacitor between the antenna and ground lugs. I don't know why this works, but it does. The value I used was 100 pF.

  This older radio just happens to have a pine base that is the exact same size as the one on the Ozark Patrol. Notice it has warped. It was sitting on a shelf. Air couldn't get under it, but the top side was free to absorb moisture from the humidity in the air, causing it to warp.

Give the base a coat of polyurethane, lacquer, or paint before assembling the radio.
   Tip 5: Consider putting some feet on your Ozark patrol so that air can circulate under it. This may sound like a crazy reason for adding feet but you'll be glad you did years from now, when you find it stashed on a shelf and the base hasn't warped.

I ended up painting the base, but I had to take it apart first. I considered replacing the base with Masonite, but it would be front heavy and tend to topple over if the batteries were removed.

   Tip 6: If you're assembling the kit and see that one of the knobs arrived with a big scratch on the front, don't fret. The silver inserts on the knobs have a clear piece of protective plastic covering them. The scratch is in the plastic. Just peel it off.

Leaking Duracell
   Tip 7: Never use DURACELL AA alkaline batteries. They leak. The company knows they leak, and has known for years but won't fix them. These DURACELL batteries in the photo above ruined a remote control toy tank. The corrosion travelled from the battery contacts to the circuit board and dissolved the traces on the board.
   Tip 7a: I use RAYOVAC batteries but all you really need for this radio are those "Sunbeam" batteries from the dollar store, and you get eight in a pack for a buck.

   Tip 8: There are several types of LM386 amplifier kits on ebay, as well as some that are already assembled. If you get the type above, the jack is the INPUT, not a headphone jack. You don't need the jack, you can hardwire it.

7000 kHz
   Tip 9: The dial scale is somewhat accurate, but if you have another shortwave receiver you can use it to set the tuning knob. Tune the second radio to the frequency you're interested in, then advance the regen control on the Ozark Patrol till it over-oscillates. Tune the Ozark Patrol till you hear a pop in the second receiver. Carefully adjust the tuning till you hear a steady hiss in the second radio, then set the knob on the Ozark Patrol.

I've found that it drifts slightly throughout the day.
