21. Topband: FW: Tuning 160M Dipole (score: 1)

I would rather guess you should short it by at least 4-6 foot per side. Easiest way is to check for the resonant frequency and short accordingly. 73 Peter, DJ7WW I put up a 160m dipole but now need t

I worked about 40 stations during ARRL 160m by S&P. Best signals strength occured between 21:00 and 22:00 UTC both days with VY2ZM peaking S9+20db. That is around your sunset at the east coast. Band

The dx window was useful when only the range 1832-1835kHz was allowed here. Nowadays we can use the whole spectrum starting at 1810kHz with some power limitations above 1850kHz (75W) and higher (10W

What a nonsense. Do you expect a station calling cq during a contest in the DX window and being called by a non dx station to qsy with that station to a frequency outside the dx window? And how many

I agree when the discussion is about the ARRL 160m contest only. But, how many stations outside W/VE can share those 5kHz? 73 Peter, DJ7WW I stand by my suggestion and I don't see my suggestion as no

What do you think 10 callers in Europe will do? And nobody will stop for as long as 2.5 sec. So only the strongest stations in Europe would benefit from a dx window. 73 Peter, DJ7WW Art A DL wondered

I am very interested in the comparison. I am almost daily on 40m SSB at about 15:00 for LP with a couple of friends. The San Diego area is also good for SP a bit later. RBNs in Europe most of the tim

I feed my tower at a height of 21m against one radial and have KLM yagis mounted at 25, 31 and 44m (top of tower). So far I never had a problem by running high power on 160m and no change in SWR on t

Yes, I am quite happy with those home brew baluns, but there is a caveat with them. All the antennas are far too high in frequency and the tips are not long enough to get the adjustment down into the
