In an earlier post to this reflector, Carlos, N4IS, mentions using one pair of twisted wires out of a CAT5 cable to feed the delta loop antenna used by T6LJ. I am assembling the pieces/components nee
To embellish the below some, the twisted pairs in a CAT5 cable have different twists, e.g., Pair color[cm] per turnTurns per [m]Green1.5365.2Blue1.5464.8Orange1.7856.2Brown1.9451.7 So, one would assu
Well, Jim, here is what N4IS stated (bolded words my emphasis) - looks like he found the twisted pair to reduce the noise OR am I reading it incorrectly? Or are there two different noises being discu
Bruce and Jim: I will have 9:1 transformers at both ends of the antenna (going to make it "switchable" for east and west directivity) as well as a 2:1 transformer just prior to the input to the shack
Well, I have the wiring scheme all written out and plan on labeling each connection and checking twice and three times b4 soldering up the connection boxes and then connecting to the loop itself.....
When asked, these days, how my day is going, Charlie, I respond with, "Going great 'cuz I am on the green side of the grass"! _________________ Topband Reflector
Heck, got on 160 yesterday morning and called CQ -- had a nice chat with W7CB near San Luis Obispo, CA....wonderful copy on both ends, he with a KW and me with 30 watts. Go figure - two guys on Top B
My intention, this summer, Charlie, is to hear and work one if those VKs.....Have worked many KH6s and JAs but in the winter months so, yes, one or two of them "in the log" over the summer months wou
Well, I work JAs with QRP power, Charlie, but that's during our fall/winter season so I expect every drop of power I can muster out of my little HF Packer Amp will be needed for KH6, or JA OR VK duri
I have two impedance transformers wound on BN 73-202 cores that I can use for the 2:1 impedance transformer I need for my FO0AAA delta receiving antenna. One has a 2 turn and 3 turn winding- giving a
I received enuff "info" and thoughts to know I'll utilize the 5:7 winding version. Thanks to all that replied! 72, Jim Rodenkirch K9JWV I have two impedance transformers wound on BN 73-202 cores that
When time permits, Charlie, I will do just that! Almost done with everything up to the two boxes with the switchable components - resistor, xfmr - as I await the xfmr(s) arrival. Outta be listening b
The J-310s in my little preamp are kaput - I looked at Mouser but the shipping costs are way too high for a couple of little Jfets - any body have lots of extra J-310 (or equivalent) they could spare
Oooops - forgot to mention quantity -- four would be nice (in case they go south again) Jim R. The J-310s in my little preamp are kaput - I looked at Mouser but the shipping costs are way too high fo
Bill - I was on this morning, listening for the YW5X station and calling CQ periodically - worked two west coast stns...W7IZ and K7CF (received a 599+ 10 from K7CF and 599 from W7IZ) but didn't hear
