Re: Topband: Recommended Antennas for 160M/80M Receiving

Re: Topband: WTB: Guy wire stuff - please be safe

Be very careful with real world testimonials - giving advice to use products for the wrong application is really dangerous. We are talking about serious tower projects that can turn fatal if you use the wrong equipment. I don't care how high the tower is. PLEASE USE THE RIGHT STUFF! If anyone

Re: Topband: AM broadcast tower and 160m dxpedition

I recently did almost this same project in Tortola, BVI (VP2V) 4 weeks ago. I have been helping as a consultant to ZBVI for the past 20 years. I was part of the team that installed a new 300 ft tower for ZBVI when the old tower came down due to an accident with a guy wire. The station goes off

Re: Topband: Contest in progress - few signals

I was the topband operator at K3LR this weekend (loved every minute) and I echo Andrew's (at W3LPL) comments below - with the directive receive arrays it takes both of us a few seconds to find out which direction to listen to. Many times the signals are QRP USA callers - so a bit of digging is in

Topband: Steady Carrier on 80 CW

I know this is the TopBand reflector - but there has been a carrier on 3501.4 for the past few days - that needs some DF work. It peaks at 150 degrees from K3LR so South South East. It is S9 this evening Any ideas on what it is and where it is coming from? 73, Tim K3LR
