If you put the RX front-end at the remote and the back-end at the house, the big issue will be dynamic range, especially with a crowded band like 160. Since the filtering will be at the back-end, th

If anyone wonders why they don't hear K9DX on 160, the answer is that an ice storm took all 9 antennas down. As preventative maintainence, last summer I replaced the rope guys with 1/8 inch phillystr
The spacing is very short to do much good on 160. close for 80, and too long for 40. Maybe get one of the noise cancedlling boxes (like MFJ) and fiddle the phase on each band to what you like best.
Certainly the SDR is of no use in contests .... but I used one of the European sites to do some antenna pattern checks, and to compare antennas ... wow is that nice. John K9DX _______________________
I have not been able to find tubing akin to what titanex uses.... By the way I have 18 Titanex in the air. (and lots of scrap on the ground). If someone needs a piece or two for a repair let me know.
All of my antenna came by air. No big problems... You can go to the airport and pick it up after some customs hassle or they will transfer it to a truck carrier and it will show up at your house. The
A 500 foot beverage is very useful .... there is no majic on the exact length. jOHN k9dx _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
I put up the killer beverage to europe... two staggered 1500' phased with two more spaced 5/8 wave. It was useless .... I shortened them to about 700 feet and it worked fine but not much better than
There are many complicated things you can do ... but if you are in a quiet location I would keep it simple,,,, 12 820 foot beverages all radiating from a central point every 30 degrees,,,one transfor
I have listed for sale the Farm property that has the K9DX remote site located on it. ( See ON4UN book) It is in Hebron, IL, Prudential MLS#07639802. If purchased by a ham, I will include all radio e
The dx window is very important also here in the midwest. It is a place for dx to go without being CQ'ed off the frequency. I do not work US stations in the window, and hope that the gentlemans agree
At one point I tried a 600 foot beverage in the lake in back of the house ... had to submerge the feed point to keep it from recieving. Results same .... directivity ok .... signals so weak not even
I will be dismanteling my remote station this spring and have: 9 special beefed-up Titanex 110 foot verticals with 160 loading coils, guy posts and Philystrand guys..... $3000 ea 8 special beefed-up
You can take an AM signal generator, feed the radial against ground, and use a little portable AM Broadcast radio along the ground to track the wire. It will work even if the wires are quite deep. Jo
It seems the thread was gone off the original subject, but .... and it may have been mentioned before .... but with my arrays I used an LP-100 with a low power transmitter as a source. The high signa
When you switch directions do you see any (even slight) change in the swr or power into the dummy load??? How far do you have to move the frequency before you see power increase in the dummy load?? J
There is a problem. I had a 4 ele 40 and 5 ele 20m klm on a loaded tower. I had a coax balun on the 40 ...... arced through the insulation where it was taped to the boom and the neighbors reported to
There would be little advantage with the loops because once the side/rear response is 20 or so db down, the RDF is determined by the width of the forward lobe. John K9DX _________________ Topband Ref
