AM CW Transmitters.

Hello Eric.

I’ve just watched your presentation video from the recent conference. It was very well put together, I loved it, the phases of the moon analogy really cements a basic understanding of the Four Quadrant Theory. I thought it was very good value as well, I hope many purchase it & the proceeds fill your pockets! (And the Lab).

I know you want to see results, or see the work in progress thus far from those around the world, those working on the various EPD type projects, (CRI, CIG, TMT, & the Cosmic Ray Detector). Some have gone somewhat quiet due to the recent ‘trouble’ but let’s hope they return soon.

I’ve been quietly working away (when I have available time and funds) constructing a power supply and an AM transmitter. Sometime ago you said that the ‘wright of passage’ was to either construct a Crystal Set Radio (hence the CRI) and / or to build a 100 Watt AM transmitter as a place to start.

So I’ve been studying / learning about and AM CW tube transmitters (Boat Anchors). I’ve still much to learn on the subject, however I’ve nearly completed (await the arrival of some mA panel meters) construction of my first 100 Watt CW AM Transmitter and the matching power supply to go with it. (6.3V Filament supply, B+ low 250-300V, B+ high 750V).

- This transmitter is a two stage transmitter, using a 6AG7 tube and two RCA 807 tubes in parallel. (Not push-pull right now, that will come later with more experience). The transmitter will be operating on the 160 meter band, (In my case 2 Mcps) and / or with interchangeable oscillator coils for 80 & 40 meters. Rather than using a crystal I’m also building a broadband VFO (1M – 21M Cps). This VFO is solid state, though which you wouldn’t like, but I’ve got to work with the equipment I already have & can afford. Once my frequency is determined / established, I can lock it in and go without the VFO.

So the transmitter power amp stage (x2) 807 tubes will drive the tank circuit of the primary coil(s) of the either a TMT or CIG. (The CIG actually). Later, once I have more experience with the system, I have a couple of much more powerful transformers (extracted out of scrapped laboratory equipment) with 2500 Watt (plus) plate supplies, to be used with 304 tubes. (The 807’s can drive the 304’s). This will come later, when I know exactly what’s going on, & what I’m doing as I don’t want to electrocute myself dead in the garage!

So over the weekend, I’ll take some photographs to show my recent progress, along with the basic schematics and post them here.

I think this is what is needed most of all now, to return to practical activities of building, experimenting and the sharing of results.

Take care.
Sputins.

1. I gave an analysis of the Colorado unit on the EG Forum some time back and must find it. The system there was about 95Kc unloaded and 45Kc with the full size bast and ball.

2. For 1860 the turns will be proportionally less. The ratio of 45 to 1860 is square rooted to scale inductance and capacity. 0.02419 tge ratio, the root is 0.15553. Hence the inductance and capacity is this time the values given for Colorado. The turns will come about accordingly, in general the length of wire varies with frequency. This is going to be the principle parameter.

3. What you are seeing as "Radiation" is the change in Earth potential around ground connection. The Earth is emitting lines of force.

Thanks Eric. Your analysis is here

http://www.energeticforum.com/renewa...tml#post202262

The reason I'm asking that is because if I scale it down then I'd like it to be as accurate as possible. I sent a file to Aaron by e-mail, I don't know if you got it. The way I've calculated it so far is to start with the end frequency with mast and take the ratio of that to the secondary alone frequency, then the secondary is scaled down from the full size secondary alone. So I'd like it to be done right and end up at the right frequency, or am I just being too fussy in wanting to find a more exact figure. I'm guessing you must have calculated the end frequency with mast from the inductance and capacitance rather than Tesla stating the frequency, the closest I could find was 45.496 kc and I can't remember what now but I think Tesla was referring to something else there.

If I start with 45 kc and scale to 1860 kc, I get a secondary diameter of 36.2cm with a required extra coil inductance of 2.7mH and 67.2pF end capacitance (using Wheeler's formula for inductance).

If the physical dimensions of the extra coil are scaled down by 0.15553, that gives an extra coil of 39cm diameter and 2.7mH which is the target inductance, but 100 turns and 122 metres of wire. I haven't calculated too many variations yet but so far I can't seem to end up at 2.7mH without an excessive number of turns on a smaller frame.

Thanks for your help, and I was loving some of your answers in the live interview just now!

This is the circuit I'm talking about -

[blackchisel97]

Hello Eric,

Would it be possible for you to answer one question regarding one project which you're involved quite while ago (20 some years). I did replicate this setup together with log periodic antennas, exactly as you have design them. By the way, this is brilliant and they indeed "work" without power being connected. I'm talking about Multiwave Oscillator. I was hoping to ask during the webinar but there was no time for live questions.
There was a variation of this circuit with two small (1/8") spark gaps at the antennas feed. What would be the benefit of such setup versus single spark gap. I have two setups running, both using bipolar TC but one is spark gap driven and the other is semi solid state (with spark gap as well).

Thank you

Hello Eric, I hope the book is coming along well. You mentioned before that the Colorado Springs coil working frequency was "near 45 kc", is there a more precise reference somewhere, was it a frequency or did you calculate it from other factors? Because I can't find a frequency in CS Notes, only Tesla stating when he describes the pictures towards the end that the frequency is "about normal", but I don't see anywhere that "normal" is defined.

If a scale model was made for 1860 kc the secondary would be a reasonable size, but if the extra coil is kept at 1:1 height to diameter ratio with 100 turns then in order to get the required inductance it would be relatively massive, the diameter is bigger than the secondary. The secondary would be about 36cm diameter, but the extra coil would be 39cm. How would you suggest about going about this in order to arrive at a particular inductance? A longer coil similar to the Wardenclyffe type design but with a lot of turns? Another inductor in series before the extra coil?

I was originally thinking of building for 1810 kc because I came across this a few months ago, originally on the RSGB (Radio Society Of Great Britain) web site but they've taken the page down since. But it seems like experimentation is encouraged, would it be wise to contact RSGB or Ofcom (FCC equivalent) to let them know what's going on in advance, in case they come looking one day?

RSGB proposal for experimental amateur radio access to 500kHz - Spectrum Forum - Radio Society of Great Britain

Abstract

A proposal is made for radio amateurs in the UK to have access to frequencies between 501-504 kHz or 508-515 KHz at a transmit level of 10W ERIP, in order to extend their experimental work, and thus understanding of low frequency propagation mechanisms, from work complementary to 73kHz, 136kHz and 1810kHz. The two frequency bands options are proposed, as they are no longer used for maritime telegraphy in the Western hemisphere, their usage for non-directional aeronautical beacons (NDB) is being phased out. It is understood that it is unlikely, in the near future, that the channels will be re-allocated to another service.

Experimentation rationale

A frequency allocation around 500kHz will offer a number of unique opportunities and capabilities to the amateur service. This will include ultra-reliable regional ground-wave communication, and secondly, further significant opportunity for extending the traditional merits of amateur radio – operating skill, self-learning and social interaction – and also the broad benefit to the national science and engineering skill and knowledge base.

UK spectrum regulation and its attitude to licensing amateur radio activity has for a number of years been innovative. In response the UK amateur has shown respect for its privileges and made good use of opportunities to experiment with new frequency bands. Examples are the temporary allocation at 73kHz[1] and currently the experimental access to channels at 5MHz.

Whilst it is legendary the way in which radio amateurs, in the early years of the last century, were able to demonstrate the usefulness of the HF spectrum, it is still possible for amateurs to contribute to knowledge about radio propagation. This is because amateurs often tend to study and then exploit anomalous propagation. Examples of this, where recent findings on a long-term study the transatlantic path at 73 and 136kHz[2], and more recently, the unexpected long-path propagation between Rodrigues Island, in the Indian Ocean, and the West Coast of the USA on 1.8MHz.

The amateur experiments at 5MHz are aimed at the long-term collection[3] of data to understand and predict quality of service for inter-UK communication at that frequency. Apart from collecting and aggregating station logs from participating amateur stations beacons are planned[4] that provide S/S+N and multipath/doppler assessment on either a manual or automatic basis. Preliminary discussions have been started with Bath University for assistance in analysing the complex set of data in order that scientifically valid conclusions can be drawn from the work.


Rationale for 500kHz

Ground-wave (also called surface-wave) propagation at low and medium frequencies can provide reliable communication over medium and large ranges. The ground-wave signal propagates along the surface of the earth. Such communication is omni-directional and continuous and is therefore well suited to nodal or network type of communication. Since the ground-wave signal is not dependent upon the ionosphere, communications based upon ground waves are not interrupted by solar events (sunspots, solar storms, coronal mass ejection [CME]) or a high-altitude nuclear detonation that disturb the atmosphere. A recent burst of solar activity (November 2003) produced significant aurora and disrupted HF ionospheric communication for days.

The optimum frequency for ground-wave communication depends upon the aerial efficiency, ground-wave propagation loss, atmospheric noise and of course man-made noise local to the receive station. Given typical capabilities of radio amateurs, where aerials are far smaller than comparative commercial installations, the best S/S+N per watt of transmitter output occurs in the range 400 to 600kHz[5]. A frequency of 500kHz would therefore be ideal for low-information rate emergency communications, which was its rationale for being used for so many years as the maritime distress frequency. An aim for the initial experiments would be to confirm that within a 1Hz receive bandwidth and 10W ERIP from the transmit aerial, the estimated ground-wave coverage of 300km can be realised for S/S+N of 20dB[6].

The radio amateur’s propensity for studying anomalous propagation is a part of the rationale for seeking access to 500kHz as it is situated part-way between the two existing amateur allocations at 136KHz and 1810kHz. Skywave signals are a feature of both of these existing bands, more predominant at the latter, but never the less also after a CME event at 136kHz as a propagation enhancement. Amateur access to 500kHz, would allow studies to be carried out to assess any anomalous skywave propagation. This would be an important part of the study given some continued usage of the frequencies elsewhere in the World.

...

Also, in my last experiment using about 23mW of power I gathered that the area of the garden around the transmitter earth terminal basically "radiates" for lack of a better word the signal that's being transmitted. The earth itself shows similar effects to the "wireless" that people usually play with around the top capacitance. Very interesting and surprising stuff with such low power. Do you think that if the earth was in resonance and using adequate power, with all the conditions as Tesla intended, would the earth have "radiated" energy like this? I don't think that's the right word to use, but there seems to be something detectable beyond the physical boundary of the earth. By sticking a metal rod into the ground, what's left sticking out overground can act like an antenna radiating a signal that can be picked up with two diodes and a crystal earpiece with no physical contact to anything.

Thanks

Copper or brass primary coil

Hi Everyone!

I want to duplicate the primary coil from the video of Eric. Later I want to use this coil for telluric work. It will be my first experiment but I have read a lot of the theory and posts here.

My question is. Can I use the copper foil from a coax cable for the 1 inch wide and 0,01 inch thick brass primary coil sheet?

http://ssb.de/pdfs/6080_EcoFlex10_k_en.pdf

Or are there better suggestions? I searched a lot already but flat cable or flat coils to unwind are not so easy to find in Europe.

Regards!

Let me add that I found this document:
http://www.tuks.nl/pdf/Eric_Dollard_..._Coils_OCR.pdf

As to physical construction the primary should be sheet copper of great conductor width and large loop area. Large surface is required as the skin effect is total with impulses. Large width also minimizes inductance allowing for larger capacitors and more rapid discharge and hence high impulse strength. In opposition to this required inductive reduction is the need for a large area due to the flashover and coupling requirements. Hence a balance has to be established between the need for minimum inductance for rapid discharge and for a large magnetic field, resulting in large inductance. The formula for inductance (rationalized) is L=area/width.

So I need 10 mil coper sheet 1 inch wide. I guess the coax foil is to thin for the primary coil.

And to Eric a reminder from Ghandi:
Humanity is an ocean; if a few drops of the ocean are dirty, the ocean does not become dirty
