Mike I understand that, I know several friends that enjoy JT modes, I used it a lot on Meteor Scatter and few QSO's on EME, Actually I gave up on EME because I like CW and really few JT modes boring,
JT is not CW and not SSB, why it is not a category by itself. SSB CW and Digital. DXCC JT modes. Regards JC N4IS In reality, this is why we have triple play and mode specific awards. The CW only peop
Hi folks Let me add some comments on Gary and Bruce savvy remarks. The real question is "how many antennas you have for 160m?" Using Manuel example, one inverted V and one vertical, for most of us, t
HI Greg You need to detune the tower and the 4 square will work fine. But if you want to have a good RX you need a Horizontal Waller Flag at 140ft or more. You can see the two webinars about Waller F
Hi Lee Good question, The HWF has a deep null on vertical signals, propagated noise like ground wave can be attenuated over 80 db. The tower on the center of the WF does have little effect adding noi
Hi Lee I remember it very well, but my comparison with the 8 circle is compatible with the RDF, the WF has 11.5 db and the 8 circle can be close to 13 db RDF and it is a winner, that 1.5 db EDF does
"Has the world really turned upside down and what do you think the future holds?" Hi Steve On the old days we used to call CQ several times and listening, very few people realize what listening reall
Hi Top Band lovers The emotion should be aside , lets dig into the technology and ask why things are that way nowadays. Computer is not only part of the radio but the radio itself is a computer today
Hi Vince , just answering some of your questions for technical reasons, I see all innovation as good for the hobby. RTTY, a very popular mode among DXers and contesters?<< FT8 you make a decision wit
Hi guys Before anything else, don't trust MFJ269 reading, transmit with 10 w and measure the SWR. It is very common the energy from AM broadcast stations changes the real impedance reading on portabl
Hi Jerry Any cable/wire is an antenna. If it long enough or near 120ft it will work like a 1/4 wave vertical. The path to the ground is important because the current will add to other circuits at the
Hi guys Yesterday the propagation was very good in general, however a very important even happed. For the first time in several years the polar path to zone 18 was open for most US states, down to Ce
It seems to me that DX conditions have been pretty poor for the past 10 years on 160m . . . << Hi Roger I see your point on things changing. However I have a different experience. The noise is up. E
Hi Trevor Any open frame relay like that can destroy your reception. I feel sorry to see people selling and even recommending this type of relay, it is a shame. The issue is speed and not current. Yo
Hi Carol The big issue with any RX antenna is common mode noise, the feed line can interact with all other wires in your station, including AC wires 115Vac, rotor cables etc. Try this, on 9:1 transfo
Hi Petr I kind understand your request, however I would like to share my view, Beacon on 160m is really DQRM, like YO on 1810.5 running 100w. Several DX stations runs 100w and work thousands of QSO.s
Wes I agree 100%; different protocol for two different species. I have ears and not a USB port! My PC does. N4IS JC So what's the protocol when a CW man checks a frequency, hears nothing, sends a cou
Hi Rich " The problem here is that any loop antenna inherently has a noise temperature of 300K, because it is lossy, and because it "sees" the earth" Would you elaborate on that? Small loop 1/10 of w
The antenna in question is not a "loop" it is a terminated loop, the diagram is a cardioid, it is very broadband 1-10, like 1 MHz to 10 MHz or 3 o 30 MHz with the same irradiation diagram. The behav
Hi guys I would like to share some papers from my good friend (SK) Dr Dallas was a great experimental guy that loved Mathematic and AM DXing,. Dr Dallas with a strong personality and seniority some t
