FSCAN2 to drive EMEM devices

[Guest guest]

Hi All,

With some help from someone on this board, my husband will be finished

making an EMEM device next week. I am going to use an FSCAN2 to drive

it. I am going to use an RF Choke from Radio Shack on the FSCAN2 cable.

Just to be sure I don't explode either my FSCAN2 or EMEM devices, I

have a few questions:

- I am assuming I should use the RF Choke on a cable coming out of the

Output port of the FSCAN. Should the choke be used closer to the

FSCAN or the EMEM?

- I plan to use the positive square wave ouput of the FSCAN. Is it

important that I use the 5 Volt peak to peak output, or the regular?

- I read that the EMEM devices powered by the ignition coils can only

handle up to 12000 HZ. The FSCAN2 can output in the MHZ range. What

will happen if I attempt to run frequencies in the MHZ range into the

EMEM device? I would love to be able to run Dr. Sutherland's latest

Lyme frequencies into the EMEM device.

At the moment we are planning to use the MSD 8222 coils, though Dr

Loyd's post about the alternative coils is interesting.

Thank you all,

Sue

Hi Sue,

Ignition coils won't produce high voltage (HV) at freqs anywhere

near 1MHz. Not much over 10kHz. You won't damage anything. It

just won't work.

Also, the RF choke won't protect your FSCAN against possible

damage from HV. You need to also wire the negative 12VDC of the

EMEM to Earth ground to be safe.

EMEM devices are limited in frequency by (1) the ignition coil used,

(2) whether a spark gap is used or not, and (2) by the type of tube

being used. Phanotron tubes will more easily run higher frequencies

than will the straight tubes. Spark gaps limit the upper end of the

frequency range. Depending on the coil used, EMEMs will do over 10,000

hertz IF using a phanotron tube, MSD high-frequency coil, and no spark

gap. (I have run the phanotron to 100,000 hz in a lab setup not using

an ignition coil.)

Machines using a spark gap may have to have the gap set to 0.001 " or

0.002 " in order to get up to 10,000 hz.. There just isn't much output

from the coils up that high. Regardless of the " chaos " signal which

may or may not contribute to the " Rife Effect " energy, that's why I

elected to not use spark gaps in my EMEM machines. One factor I did

find important is that standard ignition " resistance " wire should NOT

be used .. It really cut down the energy to the tube.

Hello Sue,

It would seem that the solution is not so difficult. Let's look at it simply:

1. A simple faraday cage [an old burned out microwave oven for example].

2. Increasing the length of the coaxial leads from the FSCAN to the EMEM so

as to place your FSCAN out of the strongest areas of the generated field.

3. Installation of magnetic filters on all lines [permanent ferrite magnets]

connecting the FSCAN to the EMEM.

4. Preprogramming your entire sequence and playing it from a tape source,

thus assuring accuracy and the benefits of an analogue delivery.

Just some ideas,

Mike wrote: HI Sue,

Bill and others have made reply but, as Bill said the RF choke

will not stop high voltage.

A choke across the line would for DC but to do that and not short audio down

to 20 Hz would need an iron core and weigh more than both of you. Plus you may

wish do go lower that 20 Hz so that's out.

What may help in this area is if you add a pair of diodes in parallel but

each point the opposite direction, then regardless of polarity, the undesired

signal, once over the ~ .6 volt conduction point, will be shunted to the shield

of the interconnecting cable.

If the voltage there is more than this then use say 6 or 12 volt zenner

diodes.

The idea is that the diodes will not conduct in the normal operating voltage

range but will once that point is reached.

The diodes have a band on one end, so you wire it with the diodes parallel and

a band on each end.

This in turn goes across the hot lead and the shield. If you wish, add the RF

choke in series with the hot lead, if you wish add another in series with the

shield.

Adding a bypass cap across the Signal generator side of the RF chokes may

well attenuate the signal there, unless it is VERY small in value.

If your signal generator voltage is kept under the conduction point of the

diodes, they will have no effect on the waveform. Regular power supply diodes

are OK if you are looking at under .6 volts, else you can string two in series

per pair half and the conduction point becomes 1.2 volts, etc.

If you had 6 volts out, then you can string diodes to 7 volts, one set

pointing one way, the other reverse.

The idea is to steer any voltage above a set point right to the shield and not

enter your equipment.

A higher voltage spike will get shunted safely across the diode path.

Again, be careful of what size bypass cap you use, else it will bypass the

desired signal generator output, too.

That value would also depend on the impedance of the generator and the target.

Mmm, you forgot the transistor choice. I get lit E-gas tubes at 50KHhz out of

emem all

the time.

Yes, and I've managed to get over 100 Khz on a non-ignition coil machine

with a fast FET.. but most people are using ignition coils which are

pretty much dead at 10 Khz to 13 Khz..

(or, you weren't really driving it at 50 Khz, but at something else.

Some PC frequency generators will generate so much " hash noise " that the

EMEM may be running at that noise frequency, rather than what the

frequency generator output is set for. Out of curiosity, did you use a

photosensor and frequency meter and read the 50 Khz off the tube?)

Hi Dave,

Do you have any interest in sharing the information on using a FET as

a tube driver? schematics???

thanks,

No, this was not hash, quite clean looking in fact. What sort of coils

are you using? TV coils or something?

Most high voltage " coils " are transformers. The word coil usually

only applies to a automobile type ignition coils. Both

transformers and coils are limited to a certain frequency range

and it doesn't seem likely that you could find one that will

operate from a few Hz to 50kHz or more with good performance at

both the low and high ends.

Hi Bil,

We have found that, using a switched multiple tap 3-core coil we were able to

get a 0 - 65Khz response without problems. Having an excellent coil winder

available in the city we are blessed. However, we now never go above 15Khz for

any of our work so we use a single core flyback style step-up transformer.

If you are looking for a high range like you are talking about try using

multiple coils, and talk to a transformer shop about winding some good ones for

you.

Yours,

Dr. Ian MacLeod, Ph.D.
