The principal effects of low height are a loss resistance induced in the wire from the ground, and a reduction in propagation velocity along the wire. A counterpoise can be considered to be an artificial ground. Its input resistance at resonance is equivalent to the input resistance of a true ground connection but its resistance will never be as low as a good ground. To provide a lower input resistance three or four counterpoises can be used in parallel. Or they can be resonant on different bands. New program C_POISE estimates the performance of a single coil-loaded counterpoise. The number of turns on a coil of given length and diameter needed to resonate a low wire to 1/4-wave resonance is calculated. The input resistance at resonance is also estimated.. All program output data is approximate due to the very low height of the wire above ground and uncertainty in the characteristics of the soil or whatever other materials may be under the wire. The wire may be allowed to rest on the ground surface but uncertainty will be at a maximum. It will nearly always be needed to prune the wire length for resonance. Or when the wire length is fixed the coil turns may need adjustment. When wire height exceeds wire length accuracy is much improved. Input resistance at resonance will be fairly small. Working Q will be high and the counterpoise will behave as a short antenna. For precise resonance the wire will still need pruning. Download program C_POISE in a few seconds from website below and run immediately. ---- ...........................................................

I had the same experience. The DX-60B may have had a well designed modulator and you have it adjusted just right. (also you are not trying to over drive the final). A plate modulator for a low power rig would make sense if you really want to operate AM and put out a good signal.

When you disassemble a power transformer you will note that the laminations alternate (IE: open end of even numbered "E"s point left, odd numbered ones right). If you took apart a filter choke you would find that ALL the laminations were oriented the same way. For an audio transformer, arrange the laminations in groups, and alternate the groups. Divide the total laminations into 3-10 groups. Why? In the case of the choke, which must carry DC, we don't want the magnetic flux to saturate or the inductance will start to drop at some current. Having all the laminations go in one way leaves a nice air gap in the core which prevents core saturation. In the case of a power transformer which carries only AC we want the magnetic flux to be tight to keep efficiency up. For an audio transformer which must carry some dc (tube plate current), and ac (audio), a mix of these works out best. Note that in the case of a push pull primary (modulation or output transformer) the balanced dc current cancels out and we don't get much saturation of the core. A single ended output transformer WILL have this problem, as will the secondary winding of the modulation transformer. A swinging filter choke should have some core saturation, probably it uses two or three groups of laminations.

The lower this resistance better it is. It is the 'ground' connection for the antenna. (And the transmitter). But there's no point in making it longer than 1/4-wave. This increases coupling with the ground, increases loss resistance and also undesirably increases radiation resistance. The counterpoise then behaves more like a very low antenna. When it is 1/2-wavelength long it has a very high input resistance and is entirely non-effective. It may just as well not be there. At some lengths the loading coil would have to be replaced with a loading capacitor. Remember, the antenna wire plus counterpoise is behaving as an off-centre fed, bent, dipole with the lower section being very near to the lossy ground. (Whatever the ground is). We don't want the lower section to be TOO long. The current into the counterpoise is the same current as is entering the antenna. If there is an antenna tuning unit it will tune up the counterpoise simultaneously with the antenna. They behave together as one thing! So there is no point in having a separate tuner just for the counterpoise. Maximum current flows into the counterpoise at the same time as it flows into the antenna proper. The purpose of the loading coil in the counterpoise is to provide a low impedance connection to the braid of the coaxial feedline. If there is no feedline then it provides an artificial 'ground' for the transmitter plus tuner. And all the foregoing arises because it is difficult or impossible for the station owner to provide a set of buried ground radials. ---- Reg, G4FGQ Article: 96509 of rec.radio.amateur.homebrew From: Kerry Miller Subject: Re: Another power supply project References: <84YDf.148864$WH.136453@dukeread01> Message-ID: <99NEf.149906$WH.8515@dukeread01> Date: Fri, 03 Feb 2006 12:19:40 -0600 Martyn wrote: > "Kerry Miller" wrote in message > news:DBgEf.149059$WH.120009@dukeread01... > >>gb wrote: >> >> >>>"Kerry Miller" wrote in message >>>news:84YDf.148864$WH.136453@dukeread01... >>> >>> >>>>Since I'm going to have to order a chip for that Astron PS I was working >>>>on, I dug out another old PS that died a few years back.

Just an antenna, a tuned circuit, a diode and earphones. There could be more sophistication such as using an amplified speaker and higher-Q tuned circuits. 2. Try a direct-conversion receiver. It may be just a more sophisticated crystal set with RF preamplifier and on-frequency crystal filter. A product detector could be included to convert to audio, but a diode detector should work and wouldn't change the audio tone frequencies. I considered using this direct-conversion approach to obtain an accurate 10 MHz signal. I wanted to use it to synchronize my oscilloscope so I could adjust a counter's timebase (or vice-versa). However, I never built it after finding a Rubidium controlled oscillator on eBay.

Huh? Yes, he is well into RF and construction techniques will be different. But while there are advantages to air-coil cores, their use in recievers went out with hollow state detectors. Even in transmitters they tend to be only used in the KW neighborhood anymore. I can't imagine that even in the wilds of BC people are winding air coils and building on heavy steel chassis. ..

Be prepared to write a lot of code. Almost by definition the hardware is simple. And experimentation in software is a lot easier and less painful than hardware experimentation. But you are correct that there will probably be quite a bit of code, although not all of it needs to be written from scratch. If you graze the Microchip dsPIC forum, a British ham talked about such a project a few months ago, sorry I can't recall his name. I think he may have posted some stuff on the PIClist, too. He did use some sort of codec, along with the dsPIC. I picked up the codec and dsPIC with the intent to go down that path, but those round tuit thingies are hard to come by around here. ..

I had lept to the conclusion that OP was concerned about undesired coupling, rather than desired coupling. I think SMD inductors are typically designed so as to not maximize their susceptibility to objects in their vicinity, although not necessarily minimize it. Another issue of concern is self-resonance. Some SMD inductors have rather surprisingly low self-resonant frequencies. Obviously, some designed for cell phone service typically won't, but it is yet another parameter to fret over. ..

The two circuits are coupled together via the mutual inductance between the two spaced-apart coils. As in a 455 KHz interstage transformer in a screening can. The degree of coupling is approximately 1/Sqrt(Q1*Q2), where Q1 and Q2 are the tuned-circuit Q's which are determined by the filter's terminating resistances. Closer coupling increases the bandwidth.
