350 watt power input MAX, yet 480 watt PEP SSB OUTPUT. Hmmmmm???? He may have found a way to break the laws of physics.

Nothing beats a quarter wave antenna, mounted in the center of the roof, for a mobile antenna. Hard to do on HF though!:D

What is the purpose of the egg beater thingees on the Moonraker? Some kind of matching device?

Don't worry about it. The amplifier is working just fine. If you really want to see what the amplifier is doing, look at it on an oscilloscope, that will tell the tale. The meter cannot physically keep up with voice peaks. People on here seem to put too much stock on what their power output...

I have built 2 LFA's for 6 meters, and one for 2 meters. All 3 antennas work very well, and I am completely satisfied with them. You can home-brew one for about 1/4 the cost of buying one. Actually, I built the 2 meter 9 element with leftovers from the 6 meter project, except for the boom and...

Check out the antennas at g0ksc.co.uk. The LFA yogis are direct fed, no matching device needed. And they are wide band, to boot.

With 100 watts and a 5 element beam, 0-200 miles should be a piece of cake. I can work mobiles in Jacksonville, 70 miles away, no sweat, every day.

Bob, Bob, Bob, did you not look at the scope pattern? Do you not understand that a mechanical meter is not physically capable of keeping up with the complex waveform of the human voice displayed on the 'scope display?

Scope VS Wattmeter Here are some pictures I took today, showing output on my 590 with compressor on. 100W CW with wattmeter and scope, then 100w SSB. Wattmeter reads about 35 watts, but you see full deflection on the scope. Last picture is close up, showing complex waveform of the speech...

No, it does not become balanced. The center conductor and shield are two different sizes. Ladder line has two conductors the same size.

If you want to "roll your own", DX Engineering as really good prices on aluminum tubing that telescopes together, as well as complete vertical's. They have all the parts to put such a system together, as well.

Won't work worth a crap, unless you have an elevated radial system, if mounted above ground level. Best to have a radial system, when ground mounted, as well, despite what the advertising information says.

Heard the the guy who designed the Hex Beam on 17 meters yesterday. According to him, it is the most amazing antenna ever designed. That being said, for the money, you can't get 5 bands in one package for less. And they do work very well, with minimal wind loading. I am considering one...

I think you are worried about nothing. Audio/TX power looks good on my scope, classic text book SSB patterns. There is a difference, of course with the processor in or out. I think you are splitting hairs, here.

Here is a good read on setting up the TX audio for the 590. I have used this and it works. I also have an oscilloscope monitoring my TX output/audio, so I can verify proper operation. Note that the "power meter" in the 590 does NOT read PEP, it reads average power. I have not noted any power...

A lot of companies make those coaxial antennas for low/high band commercial two way radio and no chokes were ever used or needed. I have also made antennas in a pinch for 2 meter FM portable operation, and never had a problem with common mode currents. The LFA antennas use a quarter wave stub...

Check these guys out. I have the low band receiver, and just got a 6, 4, or 2 meter kit, that i have not put together yet. You need a good set of eyes, those surface mount components are SMALL. And a good soldering station with pin point tips. Five Dash Inc. Your Source for SoftRock Radio Kits

Has anyone looked at his signal with a pan-adapter or SDR with waterfall display to see if his signal is really that wide?

Why are you feeding an 80 meter dipole antenna, which has a native impedance of 72 ohms with 600 ohm feed line? Are you attempting to make a fan dipole? You might be better off using a coaxial feed line.

To be a true coaxial antenna the shield that is peeled back from the center conductor should be doubled back on the shield of the lower part of the antenna, making a quarter wave stub or counterpoise. Then the choke would not be needed.
