am and fm transmitter help

[Matt2 - Amstereo]

i'm wanting to transmit a radio signal to about 5KM radius from my
location. i would like to use both the am and fm bands for power -
performance compare.

i know about the audio frequency response difference, am cant go as
high, fm cant do low bass and both have inherrent problems from
electrical noise (am) to picket fencing (fm) ect.

I'd perfer that the signals be stereo (have an am stereo transmitter but
its only good for 1/2km at best) but if i have to sacrifice stereo for
distance, i will.

all Im wanting is somewere to get one pre-made,or a list of cheap easy
to get components that could be used and circuit diagram. after about
10-20 watts am and 50watts fm that'd do it i believe

ta, matt.

I know unlicenced is illegal, but aslon as i use a free frequency (mid
80's for FM and ~ 1Mhz for am (until ethnic 1053 start) and don't tread
on other providers etc it should be ok.

well ive looked throght the am and fm dials looking for local lpfm and

1601khz ams and there is none.
is there some where i can get a list of who owns what LP fm stations in

an area and if there are available licences that can be purchased? i'd
like to set up a local station in my area (just bordering the west side
of ipswich)

I have no qualms with doing it all leagal, IF i can discover the
information required ETC, i jsut want to do my own field tests to
compare methods and technical viability etc. i can AM throught the power
grid using indirect coupling and the power lines as my transmitting
antanna aswell as a stand alone radiator(low power good distances up to
the next transformer at least) and FM well thats another lot of fun. I
was thinking of trying the 3 stage fm bug kit from jaycar with upping
the power to the output stage (its 1KM out door range as is)

any help would be good, I have no one i can discuss this stuff with to
get the help i need which is why im on here instead.

get hold of a throwaway vhf synth midband mobile radio that will do 40w, ie;
midland brand.
have a play around with that around 88megs, into a dummy load at first.

the aerial location will determine your range, rather than power.

radio is fun, enjoy

Wrong on both counts.
sorry, but you are wrong, FM signals can only carry 50hz-15khz at best

to protect the Stereo carrier etc, and most am radios can only see up to
4khz if your lucky they can see below 30hz no probs (filter dependent)

** Ever try using digital FM ??

no i havn't, i'm testing to see viability with the current methods, to
see if its worth persuing a LPFM licence or LPON licence

** I hope this law breaker lives way out in the sticks somewhere.
no i don't, im ipswich based
** Got a license for this ??
I'd like to get one, if i could find out whats available, the ACA/ABA

websites don't feature a list of whats around me and if any are available

Got a brain ?
yes, experimentation is a fundamental property of the human mind

just put mr allison in you block list,
you don't have to justify youself to him or the other fanboys of the aca.

Can't help you on the high power transmitter side of things, but how about a
helium filled baloon with a wire antenna connected to it to get your height
up. The higher the better for transmission. There is a calculation out there
for the optimum length of the antenna. It is simply the length of the FM
band that you will be transmitting on. I am sure someone on this group will
be able to calculate the optimum length for you as soon as you work out
which frequency you will be aiming for. Might as well go for a full wave. I
would guess that with that arrangement, you could get way more than 1K from
your three transistor FM kit and it would be a good base for experimenting
with higher power transmitters. I wouldn't worry about the ACA on this one.
They are mostly a bunch of engineers, and would probably give you like 10
warnings or more before they fined you. I reckon even if you upset a
commercial radio station, they would still only want you to stop
transmitting, and probably wouldn't take you to court or anything. And
that's only if you were transmitting over the top of them.

Good luck with your project. Let us know when you are transmitting. We'll
see if we can pick you up!

** There is no 50 Hz limit involved.

You are stupid and wrong.

and most am radios can only see up to 4khz if your lucky they can see
below 30hz no probs (filter dependent)

** AM as a technique has no such HF limit.

There are many hi-fi AM tuners that go from 20 to 15 kHz +/- 1 dB.

** I hope this law breaker lives way out in the sticks somewhere.

no i don't, im ipswich based

** Please explain ........

** Got a license for this ??

** None is available.

It is illegal to transmit on the broadcasts bands with any more than flea
power - fuckhead.

with the power required to get 5km, you will cause interference to your
neighbours and they will call the ACA snoopers in and they will triangulate
your transmitter out .... They can confiscate the equipment.


what a wanna be.

Just some kid talking nonsense.

We told you all about this what, a year ago? AM can certainly do better than
that. Now if you didn't get around to doing all this crap last time, why
should we believe you might do it this time? Geez, it must be primary school
holidays or something...

RF equipment is virtually never worth DIYing these days. Buy one if you
can although I doubt you'd find anything *cheap*.

I wouldent worry about getting approval.

No one owns the airwaves and really, who's going to know its you anyway?

Just broadcast, and keep your frequency secret, screw the authorties

because alot has happened in the last year or so, financialy and otherwise.

Its somthing i want to do, got the software, the music, the audio
processing, just need the exciter.

you don't know what circumstances occure to people, don't judge people
like that. besides, didn't receive any diagrams back then either. i was
hoping somthings changed in recent times that may make setting up a TX
easier.

The latest Everyday-Practical Electronics has an interesting AM broadcast
transmitter project.

Won't go 5km (unless you put a lot of attention into your antenna) but the
basic circuit is sound and should be great fun.

The location of a transmitter in a urban area is very easily found.

Just broadcast, and keep your frequency secret, screw the authorties

** ROTFLMAO - a secret frequency on the AM or FM broadcast bands ????

hey i woundnt be too worried about aca...i did it for 2 years in brisbane
here. on most weekends....but i thin k you are goin alittle stupid with 50
watts....i used to use a 5 watt system... with a pair or co-phased 1/4
wave homemade dipoles of a location with a little bit of elevation and i
was acheiving siganls up to 20 kms

"was thinking of trying the 3 stage fm bug kit from jaycar with upping "

dont do it it will play up as soon as you walk near it ...and it will drift
like all buggery there is plenty of schematics on the web for 1w trasmitter
that arnt to hard to make ..

shannon

the power to the output stage (its 1KM out door range as is)

running 50 watts is gonna get yourself caught alot quiker..
