41. Re: Topband: 160M JT65HF (score: 1)

A technical clarification ... although JT65 users will specify USB carrier (dial) frequency, the software uses a nominal 1270.5 Hz sync tone with activity spreading +/- 1 KHz. The actual occupied spe

Interlocked switches should not be necessary for receive applications. If by interlocked you're looking for a way to deselect one antenna when selecting the next, check K1TTT's web site. Dave had a p

You certainly don't need an amplifier for JT65 and most are not using them. I worked half a dozen stations last night on 160 - mostly new states from here in Florida - using nothing more than my 80/4

Because 1900 and up is not available in many areas of the world. Although I'm not happy with TJ65 at 1838 - it's far better than the over driven SSB, ESSB and AM that was the norm between 1830 and 1

That is a result of WriteLog 11.01 using different registry settings. I suspect that other third party packages (third party contests, etc.) may also need to be reloaded although I have not confirmed

That never stopped the SSB and AM boys for years ... they always crowded right down to 1830 to talk across town because "that's where their antennas worked". The same thing is going to be true for th

If you want to get JT65 operation on 160 meters moved, you will need to convince IARU the Region 1 and Region 3 organizations to modify their band plans. The simple fact is that Region 2 operators *w

This is a terrible error in logic. Current on the radials will divide based on the impedance of each radial. If the feedline happens to be a "pathological" length its (outer) shield can carry *all* o

Sure - that will work just as soon as 160 becomes 200 KHz worldwide and someone manages to repeal the laws of physics as they relate to antenna SWR bandwidth. As long as major areas of the world eff

30 meters is an anomaly in that it is 50 KHz worldwide and there is no SSB in most countries. Even so, there is still friction among the digital modes - particularly with the absurdly wide, automati
