Hello to all,
As I approach senility I keep on having problems like the following: I notice on the Desert Rat PDF file, DR2, that a short note states that the coil should be wound around the PCB. I have never heard of doing this before but it hardly matters as I had planned on building this circuit on perfboard or Manhatten style, and using my usual pill bottle as the coil form. But now I am curious. Is there a board available for this project? I would like to know this method of winding a coil on a PCB as it might come in handy for a future project. Or, have I just made an idiot of myself for misunderstanding how this simple coil should be wound? I am sure I will have many who will be glad to point this out to me. 73 and good wishes to all de WA2AFD |

BTW, don't those pill bottles make wonderful coil forms? Nice high Q. Good for storing small hardware, transistors, all the stuff we used to use baby food jars for in the old days. And, the supply seems to increase every day, just like wire coat hangers. You have to do SOMETHING with 'em or they'll take over! |

I notice on the Desert Rat PDF file, DR2, that a short note states
that the coil should be wound around the PCB. Howard- There may be a misunderstanding. I didn't see the note, but had the impression the coil was to be wound on a 35mm film cannister. Looking at the other references, there were a couple of alternate plastic coil forms suggested, with differing numbers of turns depending on diameter. 73, Fred, K4DII |

Good for storing small hardware, transistors, all the stuff we used to use baby food jars for in the old days. Works well with plastic 35mm film cans as well... Carefully drill a hole in the top the size of your coax - snug fit. If its one of those fancy adult-proof tops, this may not be good. Go to a film can. Cut a slit from the hole to the edge, with the trusty ole' Exacto knife. Slip coax into hole via slit, connector towards indside of top. Pull coax so connector is up against top. Snap cover onto container. Hopefully this is useful in some way... -- Steve N, K,9;d, c. i My email has no u's. |
