Carol, N2MM Rule 6.1 for the ARRL 160... "The segment 1.830 to 1.835 should be used for intercontinental QSOs only". Note that it says "should be". IMHO, following the suggestion just makes the conte
That's not practical to enforce via logs because some participants may be using radios that have no connection to the computer other than the key line. 73 Charlie, N0TT _____________________________
Teflon wire wrap wire I was using. Without Teflon on the wires, and with normal mag wire, the enamel was easily scratched. Not only that, lightning would punch through from enamel to core, or from w

I've just used strips of sheet copper cut with snips for "flat" wire. I purchased a sheet from a Hobby Lobby store. Their ads usually include a 20% off coupon good for just about any one item at thei
FYI Bill....the use of medical grade petroleum jelly was recommended in ON4UN's LBDXing book. That doesn't always make it right, but personally, I've been using the jelly for years to keep water out
I've never had medical grade petroleum jelly attack any connectors.... that's not saying it won't, it's just that I've never had an issue with it. OTOH, I've had clear "silicone grease" attack elect

FWIW, I rigged all my PVC Beverage poles so they are simply zip-tied to metal T-posts. When an ice storm is predicted, all that needs to be done is to clip the ties and let the poles/wire fall to th

YES!! Good, no...SUPER, punch! I purchased mine over 20 years ago and it still works great! Hard to wear out. It came with a fitted metal case (then!!)....I see now it's a plastic case which, I hope,
FYI Topbanders...tonight is the last night to get W1AW/0 - Missouri on 160m until October. Freq about 1826, receiving "up 1". 0200-0400Z or 9-11pm Central. There's a ton of static this time of year,
IIRC, quite some years ago, QST had a photo & description of a FCC "signal locator" (for lack of a better description) consisting of several remote receivers that were linked together. Anyway, these
Skip, I went on a road trip to Northern VE2 some years ago. There was an enormous transmissionline near the road we were on. I tuned in 1710 khz on the truck radio and there was dead silence...NO RFI

FWIW, I did that with my 160 tower. It works, but when the wind blows the 80m antenna gets detuned. The spacing is about 18" and the 80m wire is under tension. 160m operation is unaffected. I had th
I know someone who uses aluminum plates with HDPE plastic to make a fixed capacitor. Works great with 1.5kw on Topband. Formulas to get the cap in reasonably close is in most ARRL RA handbooks. Tweek
Mike, You should use either enameled wire or something like the wire-wrap wire that Radio Shack (used to?) sells. See below on how I use enameled wire. Your winding is shorted to the core and there c
