I need a decent program for sending QRSS. I have the program called QRSS version 3.11, but it has a bug in it and I won't use it. I can run DOS or Windows anything here, so it doesn't matter. Thanks

So don't waste your money on #8 wire when the #12 is slightly lossier and a heck of a lot cheaper. Now if you have really big thousand+ strand Litz wire, then go with that. Am I right on this Bill???

What the heck, go with a 1w signal like the US guys use. You will be surprised as to how many stations you can still work if they have a decent receiver and antenna on their end. This way you won't h

Hi Mike, For our Part-5 experimenters license, there is no antenna limit. That is why I will be putting up a big loop for such use and I already have a legal vertical for Part-15 use. I hope that the

I agree with Dave G3YMC as to getting on the air with whatever it takes. Many people don't have the property to put up a good antenna. I myself have too many trees to make a vertical work on LF, so I

The loop has to be at least 13m to 15m vertically and at least 762sq meter total area or bigger to work decent. If you go with a loop of 15m vertical or greater and make the horizontal part more like

Hi Mal, When you say the loop doesn't pick up the low angle DX signals, are you using a horizontal or vertical loop??? Bill Ashlock on the east coast of the US is using vertical loops on 1750-meters

If you leave the test leads open and push the ZERO button, it works fine for cap zeroing. Short the leads and push the ZERO button for inductor zeroing. http://www.geocities.com/we0h/lf.html Dear AAD
