Mervs note reminded me that we probably need to go back to how we worked JA for many years. in this case NA transmits 1950+/-10, and receives where appropriate, and, if the Dragon is loud enough to b
cleanest and simplest answer is to run with the AGC off. I almost always use an external receive antenna with lower overall level signals, and when I add in the TX antenna as a choice on the receive
Announcement from RAST WARC bands authorised in new Amateur Radio Act Thailand's Intermediate and Advanced class radio amateurs are now permitted to operate on the so-called WARC bands (10-, 18- and
I usually just casually listen to the band on my way to work in the AMs. This AM, a foggy morning in Socal with all the insulators making noise, I was easily able to copy several JAs, rather unusual,
A bit of a me too, A substantial percentage (like 30-40%) of the North America contacts we made from XZ0A were the direct result of listening on a very high angle receive antenna. this antenna was on
There is some really good hard data coming out of all this discussion. The list of "bad" frequencies, and the country allocation list overlaid produces some interesting results, and gives some good c
I have operated topband from the black hole of Southern California for a couple of decades now (not counting the third decade under the LORAN band plan). We are in a part of the world that gets EU pr
I operated for a number of years with a 250 ft tower with sloper 1/4 wave lines attached 1/4 wave from the top of the tower. I simply hooked coax between the tower and the sloper like you would feed
Its based on the situation. In SE Asia, it appears that at Sunset it is often true that signals arrive at very high angles. At XZ0A it was responsible for something like 50% or more of our NA contact
599 is not the most common contest or DXpedition report. It is 5NN. That is, I hear you, No report, Im busy, NEXT! When conditions and signals are poor, I usually send 55N for the exchange on topband
If you know where you are, this little program will do the rest. its an old DOS based program, but runs just fine in a modern window ( not tested later than XP). Also can calculate distances just fin
Most likely to be some form of overload in your receivers or preamps. If adding a plain resistive pad reduces the product by more than the amount of the pad, its in the receiver. - (you have to use a
those should be pretty standard solid state switches. I don't recall them being a problem in the 2500 I worked on some years ago Are you satisfied that the switches themselves are the problem and not
Run it through the trees, it will work just fine. Use the slope to your advantage, it will tilt the response angle down. a one wavelength beverage is a moderately high angle antenna, 10-15 degrees of
Use flooded cable- its air spaces are flooded with goo that does pretty well at keeping water out. Flooded cable is available from many suppliers - quad shield flooded cable is pretty standard for th
The root beverage design at VP6DX was the DXE reversible hardware & 450 ohm ladder line. Worked flawlessly. I have used the DXE hardware in other applications and its the closest Ive found to playing
that makes a dipole not a beverage. A Beverage MUST be fed at the end. It is a traveling wave antenna, not a conventional coupling antenna like a dipole If you must, build the feedpoint at the end an
Make two separate shorter beverages, don't feed one wire against the other, they will effectively cancel out _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
with a two wire balanced feed and reflection transformers, etc, it will end up behaving as separate beverages, mostly, - if all the energy paths and phases are attended to, it could work, but might g
