| Longwire 600 ohm terminating resistor HB |

on 5/8/12 |
| In the past I, have used nichrome wire from heating elements of waterheaters,electric stoves,ovens and toasters during experiments of terminating longwires. I have had some success but, without equipment to obtain 600 ohms I, made due with a low budget electronic measuring device,VOM.Doubling back the resistor wire was my attempt of creating a non-inductive resistor of the homebrew nature. Any hams with better ideas than I obtain can respond and I'll listen. THX 73 n0mzr |

| I currently feed 2ea. 160m loops from the same feedline. Each of the loops are lower towards the south. Signal reports on 160M-75M are great.If I raise one of the loops on the south ends to compensate for the spherical shape of earth,is it possible to obtain better northly propagation? I'd appreciate your input. n0mzr |

| I would build a 2m "Slingshot" antenna. Vertical polarization. Look it up on Google and find your construction needs. 73 |

| There is life out there, psk-31 on 50.290 revealed w5cha and others this morning. Hope to hear more where they claim the action is minimal. |

| I am soon using the windings from an electric motor which is resonant for 30m loop.The wire is enameled and solid copper so, care must be taken but, it is of heavy gauge copper.It will be a vertical loop with a wood mast support.It will be Armstrong rotated. I will be feeding it with 300 ohm feedline to my MFJ tuner and 4:1 balun. My next warm day project.73 n0mzr |
