You had a pretty strong signal here for only 11 watts. Thanks for the QSO Eric! _________________ Topband Reflector Archives - http://www.contesting.com/_topband
Jim's right when you need a quantity of ferrites. When buying onesy-twosys then go for the retailer. I've never liked Amidon's high shipping costs. Charlie, N0TT _________________ Topband Reflector A
I like my QC-15 noise cancelling headphones! Worth the money and they DO cancel-out fan noise from the K3 and my KW amp. I don't have any clacking relays when I key, so I can't comment on that. I use
Indeed, way too fast for conditions at the receiving end. Then they wonder why their rates are down and why they're "not in the log" because their call sign was miscopied. 73, Charlie, N0TT ________
Dave, Think of the Beverage as an unbalanced transmission line. Its output is much higher because it is unbalanced with the soil/ground, even one that is two-direction and made with coax, twisted pai
Hi Gents, I need a fellow ham to pickup a small load of "radial wire" on spools this coming March 9 to March 13. What is there will usually fit in most trunks of a small car. 'Course a van would be e
Hi Tony, " Just can?t figure out how it blew the ferrite into little pieces..." If it was lightning, it's the pressure of the wires (trying to move away from one another) pressing against the walls o
To offer another view.....IMHO Measure the impedance at the base of the antenna without the feedline attached in any way. While watching your instrument (259B, VNA, etc), touch the feedline *shield*
That's right...it's insulated and is used for "invisible" dog fencing. I've used it and it's just fine for radials. It's tinned copper, at least mine was and it came in 500ft spools. I've also used t
Rich, I don't use any chokes on my 160m 9-circle RX array....located about 900ft from the shack. Chokes on the lines of your antenna couldn't hurt. Snap-on chokes may not offer worthwhile resistance.
Fellow Topbanders, I have 100ft of Twin-Ax "coax" that is surplus to my needs. It has a double shield, tight silver braids, blue and white colored twisted pair #18 solid copper, poly insulation, ~120
The twin-ax has found a new home...thanks to all that responded. 73, Charlie, N0TT _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector

I was one of the 160m ops at "nearby" FT5XO. I can tell you that when the WX was good the TX antennas worked very well for receiving. When the WX turned bad, such as during the snow storm we worked t
Yes, and I was happy to hear and work W7DRA! Haven't heard him for a long time. Charlie, N0TT _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
"Any new ideas on high performance preamps for 160m?? " The only thing I can suggest is to build the front end of the preamp as if it were a JW Miller style crystal radio, followed by the amp itself.
