Hi again, Carl Unfortunately, there are a few pages out there that I do not wish to be on, including some that say that everything has already been figured out, and there is nothing new that will eve
The short answer is you have two choices. De-resonate the TX antenna during RX or get at some distance from the TX antennas. Your modeling is telling you what the interactions are, and therefore tell
K5AF lives in San Antonio on a 75' x 100' corner lot. His general purpose antenna is a tuned doublet that starts at the corner light post and goes across his roof to a neighbor's tree in the opposite

Just remember that an FCP is a SINGLE BAND device. If you use a 160 FCP on 80 meters, the field cancellation will not occur and it will be lossy. Second, the gorilla in the room for QRP is eliminatin
Hi Bob, I had a look at your QTH via Google Earth. Would appear that the only support you have is your tower. And on something like a 65 x115 corner city lot. How tall is your tower? 73, Guy K2AV ___
Gut suspicion is that you have a relay with fused contacts or blown coil or some such, and your ACTUAL connections inside are not not what you would be expecting from the schematic. Or maybe a burned
I am getting comments from people who have installed FCP plus isolation transformer 160 TX antennas, how their new TX antenna is quieter than their K9AY or pennant, maybe a third or half of responden
Worked them during a "12" period right on 1812. He was only listening exactly on 12 and at the time was clearly having a hard time hearing. 73, Guy. _______________________________________________ UR
Do an indoor or attic folded counterpoise. FCP can be bent around walls, etc, run underneath rugs on the the floor. Keep the middle of the FCP as straight as you can manage. You still need the isolat
Sometimes the only symptom of common mode connection to your antenna is excessive "ambient" noise, usually from the AC wiring system in the house. A on/in ground radial field is not a monolithic sing
The actual ratio, or incidental winding to winding capacitance, particularly on 160m, is pretty immaterial. What is accomplished by the isolation transformer is simple removal of all possible current
Yup. Metal to metal contact with the radials, folks don't have a good mental summarizing device for radials, thinking that "ground" is some kind of sucking everything up magic medium. Text below... 7
Well, maybe they have been good at your QTH. Here, the conditions to Europe have been the worst in recent memory. Just fleeting peeps of Europe barely working through. Only honestly R5 signals were f
I'd say the conditions seemed good from East of Mississippi to East of Mississippi. They were especially good from NC to MN and IA, go figure usual 569, 579 KH6CC was R2 at best, and was only up to t
I may have missed it somewhere, but where physically is the choke on the entire run of the coax from the antenna/isolation transformer back to the transmitter? Some commentary appears to assume you h
Don't have the time to go into my personal extensive experience with this one, but there is a 2-Wire 3801 gateway now, with improved circuitry, hugely upsized cache for forward error correction for v
Oh, yeah. It will. If you are unlucky and it is presenting a current node at the antenna connection. All the MORE likely if you have a really good ground at the house entry point. Get used to it. Eac
Well, Cackle Fersus got up that morning and forever afterwards swore something was bent about the day. Nothing has seemed straight or screwed on all the way ever since, and probably won't ever be, un
