Re: [Elecraft] FW: Using your tower as a vertical - 160 or 80

Regarding using a tower as a vertical: Some years ago I had a 50-foot mast with a tribander on it next to my house. I ran two wires out my window, one down to the base of the mast and one to a point on it that produced a reasonable SWR on 80 meters. The rotor cable and feedline for the beam

Re: [Elecraft] Using your tower as a vertical - 160 or 80

Rich, Thanks for your reply; very helpful! Something similar to your shunt feeding method is what I have had in mind. Since my tower is a crankup (55 ft topped by about 22 ft of mast+antennas), I do have some misgivings about managing the wire running parallel to the tower, in the scenario

Re: [Elecraft] RX Mush, why the fuss?

That isn't actually true. Threshold and slope combine to form a point of non-linearity that can cause all sorts of in-band mixing products when multiple signals exist at roughly the same levels. I and others have experienced that first hand in the past. I can running stations in a

Re: [Elecraft] 80 Meter Verticals

The fan antenna over my house is multiple resonant dipoles on different bands with a common feedpoint. Those work fine. You can also have a driven dipole with a parallel coupled resonator of a slightly different length. This will give an antenna with a second near-resonant point and lower SWR

Re: [Elecraft] K-Pod: A failure to Communicate

BINGO, I believe we have a winner. AUTOINF is NOR, however, I use LP-Bridge for port sharing the K3S USB with various logging programs and SpectraVue software running my SDR-IQ that I use as a band scope. So there is pretty regular bus activity. When I disable LP-Bridge it *appears* to

Re: [Elecraft] 80 Meter Verticals

I know them as fan antennas. The old UHF "bow tie" TV antennas are a good example. The discussion about radiation resistance vs. feed-point resistance is specious. When feeding more than one resistance in series, such as a monopole impedance and a ground impedance, Ohm's law prevails. The higher

Erik, I've been feeding K3 RF to my house bracketed, 75 ft Rohn 25 tower for years with great success on 160 Meters. The tower is topped with HF and VHF yagis which act as a capacitive top hat. The 50 Ohm coax feedline is connected to a tap on the coil of a parallel tuned circuit. The top of

Hi Alan, Your link didn't work for me, but I assume your article describes how to make a good bandpass filter. I do in fact recall seeing such an article in QST years ago. Assuming that you were just pointing out that I can put a bandpass filter on each feedline, as is common practice in SO2R

Hi Erik, It is certainly possible to use a separate filter in the feedline to each antenna. For example, here's an article I wrote many years ago on how to homebrew your own: http://p1k.arrl.org/pubs_archive/89595 Those filters are only good for 100W or so, but there is no fundamental

I’m not sure what the original post is actually suggesting, but there are three antennas techniques like that, and all have their uses. A cage element connects everything together to make a fat, low-Q element. Those often have enough bandwidth to work over the entire 80m band. W1AW uses a cage

No, the real question is why doesn't Elecraft make a KPA1500! I agree about the Alpha PIN diodes. I had an Alpha 86 for a few years, and never had any trouble with the PIN diodes -- and I made plenty of 'antenna mistakes'. I sold it because I was tired of waiting the 90 seconds for it to warm
