Re: Topband: Top Band and JT65

JT9 vs JT65 over CW The same conversation happened when SSB started to gain strength over AM. 73 Mike va3mw > On May 13, 2017, at 7:39 PM, Mike Waters wrote: > > That's interesting. Thank you for sharing that with us. > > What software are you using, Brian? Joe

Re: Topband: Top Band and JT65

That's interesting. Thank you for sharing that with us. What software are you using, Brian? Joe Taylor's, or some other? I'm guessing you're only using the wide SSB filter. In any case, I'll have to try that and see, using CW and SSB filters. 73, Mike www.w0btu.com On Sat, May 13, 2017 at 5:50

Re: Topband: Top Band and JT65

Well said! That's more interesting to me, too. :-) But I find WSJT-X interesting to play with once in while. I mostly used WSPR to check propagation. 73, Mike www.w0btu.com On May 13, 2017 3:57 PM, "Jorge Diez - CX6VM" wrote: I did JT65 on 160, but really what´s the

Re: Topband: Top Band and JT65

I did JT65 on 160, but really what´s the challenge? Is amazing when you did a CW qso, switching between RX antennas, filters and radio adjustments to pull out a callsign I don´t know what people than been on topband for decades feel about that 73. Jorge CX6VM/CW5W 2017-05-13 17:42 GMT-03:00

Re: Topband: Top Band and JT65

Maybe some do. But I usually turn the speakers off when operating digital modes. That extra 2 dB over JT65 --as well as freeing up large portions of the band-- ought to matter to more hams. 73, Mike www.w0btu.com On May 13, 2017 3:32 PM, "Brian Pease" wrote: This may

Re: Topband: Top Band and JT65

This may sound strange, but my opinion is that hams like the musical tones of JT65. On 5/13/2017 3:27 PM, Mike Waters wrote: Why not JT9? It has a 2 dB improvement in S/N ratio on 160, while using only 1/10 of the bandwidth. I cannot understand why JT9 is used so little on 160 thru 20. JT65

Re: Topband: Top Band and JT65

Why not JT9? It has a 2 dB improvement in S/N ratio on 160, while using only 1/10 of the bandwidth. I cannot understand why JT9 is used so little on 160 thru 20. JT65 is a VHF mode. physics.princeton.edu/pulsar/K1JT/wsjtx.html 73, Mike www.w0btu.com On May 13, 2017 2:03 PM, "James Denneny"

Topband: Top Band and JT65

I am hoping more DX stations will take advantage of the JT65 mode on 1838 next season. I have been using it on 20M recently and am amazed at its weak signal performance. This mode should enhance the capture of DX entities on TB particularly with propagation decline. It's main drawback is the

Re: Topband: 160 in daylight

Yes, VY2ZM on times is still S7-9 on 160m at 11:00 local time at my location in Germany on 160m. And VE1ZZ calls in around 21:00 local time when he is still in full day light, two hours before I hear any other station from NA. 73 Peter -Original Message- From: Topband

Re: Topband: 160 in daylight

Hi Peter, The 'why not' only applies to the hams who don't want to chat with their 'neighbors' or anybody on the same continent. propagation does play into it and if you are a "DX only" ham 160 is much better at the greyline or at night. There is nothing wrong with being a DX only ham. But

Re: Topband: 160 in daylight

Hi Gang, While working at a beginner level on 160, I have dabbled with the band for many years. The subject of daylight operations brought to mind on interesting occurrence. After I returned from Vietnam, in 1969, I setup a basic station which included 160. There was a total lunar eclipse for

Hi Bob, Welcome to 160m ! Milt Jensen N5IA (sk) used his huge array in the 160m contests to work thousands of miles east and west while he was in full sunlight. (In fact I believe he was the one who sponsored a plaque for daylight operation only in the Stew Perry Contests) For some of

Fritz, I cut a U shaped slot on the top, install a short piece of tubing and run the wire through the tubing. I keep the tubing in place by placing a black UV proof tywrap on the top of the pipe. I use tubing so as to not chafe the wire. Mike N2MS > On May 12, 2017 at 9:36 PM FritzOAQ

Sure it does, why not? 73 Peter -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Bob via Topband I live in Northeastern Pennsylvania, have only been on 160 a month. I hooked up with station in Lacona, NY which is about 200 miles from my QTH. We
