about 100W, obviously...
Depends upon the overall efficiency of the rig.

An FT-847 will draw 18A while outputting 10W on 4m.
>My question is "how much power would a M3 have to be pushing from a TS-430

depends if the PA is in good shape or not.
but as usual.... the top quality training of the FL is shining through

thats some Creed-7B and ST-5-box he has there !!
The same as anyone else running the same power. However, the M3 does seem to
have said he was drawing 18A, that was an assumption by the shop owner. No
doubt you will change the story to address this, or mention some unrelated
story, but the 18A bit, by your own words, came from the shop owner.
I don't think I would be welcome at mine ........which is no bad thing......
>My question is "how much power would a M3 have to be pushing from a TS-430

If it's any more than the 400mW maximum they should be allowed, it's
too bleedin' much.
Nick.
That's what you get when you try to smuggle in a box of matches.
They've heard what you do to digital things.
Like Sherlock Holmes' dog that didn't bark, the clue to the M3's power
and skill level lies in what wasn't said:
Shop owner: "Does the rig draw 18 amps when this happens?"
to which there are three possible answers:
M3: "Yes" or
M3: "No, it draws X amps"
or the one relevant to this case is
M3: "erm, cough, splutter, dunno" (which could also easily be
indicated by (an embarassed) silence).
So, it wasn't what the shop owner said that is important here, but
what the M3 didn't say.
You may well be aware that in the current state of the criminal
justice system in this country, inferences are allowed to be drawn
from a suspect exercising their right of silence, that could be used
against them in a court of law. You might do well to start drawing
inferences from the dog that didn't bark.

i think that someone is accusing someone of confabulating !
To be fair though, if an MM3 is running 100w his ERP is nearly always
going to be at QRP levels based on some of the antenna systems I have
seen recently. For example, ATU's seem to be mandatory for new
licensees on any band, yet I have never used one above 7MHz and even
then rarely. I see it as a point of honour that I get all my antennas
to match the radio without an ATU. It makes operating easier and
reduces silly mismatch losses. Maybe I am just too old fashioned.

who said anything about ERP ?
an m3 is entitled to present 10 watts at the aerial input.
if the transceiver is drinking 18 amps at 12 to 13 volts the
1. the pa stage is completely shot
2. the m3 is sending lots of watts out the back end
>going to be at QRP levels based on some of the antenna systems I have
QRP ?
if i remem... qrp stops at 5watts not 100 watts ERP or no ERP.
then again... who ever heard of an m3 who was capable of measuring
18 amps but then didnt know the difference between 10 watts and 100
watts?
or to put it another way..
if an m3 has the ability to measure 18 amps, then that m3 must be
aware of the diffference between being-at-or-below-10-watts and
being-over-10-watts.
I have an Automatic ATU on my 847 - but I only need it/use it on top
band (where I've yet to make a contact).
Transmitter/Transciever OUTPUT, I'd say.

I'm glad you brought that to my attention. I hadn't realised the
implications too well, of keeping silent.
Dave
>Transmitter/Transciever OUTPUT, I'd say.
according to previous statements on this newsgroup and some other
info, the point of measurement is where the energy is presented to
the aerial.
and would you believe it...whilst looking for info on this I found yet
another club website which makes reference to the ADVANCED LICENCE !!!
I wonder what the new RSGB Quality Manager has to say about this ?
The content of club websites are the responsibility of the individual
clubs. Why would you think the RSGB would interfere in their content?
"If the police arrive to lock you up, say nothing...All you are doing
by trying to explain is digging yourself further in." Words of advice
from a solicitor, perhaps, or even a hardened criminal who knows how
to work the system? Far from it � this is one of the many musings of
Jack Night, a serving police officer whose anonymous blog detailing
the daily working life of a detective has won him plaudits and prizes.
The online diary, "NightJack - An English Detective", was started just
18 months ago and details the author's frustrations with his force and
attempts at the reform of policing which, he says, has turned officers
from "approachable neighbourhood figures into neon-clad
stormtroopers." "

Of course you did. Does the radio in question operate on 27mhz (sic)? If it
does: it must have been heavily modified and it would need one (very) large
antenna. Have you any idea how long an antenna is on 27mhz (sic)?
(I'd expect a G6 to know the difference between mhz (sic) and MHz).
If you must confabulate stories to overcome your insecurity, try to get your
facts right!

Problem there...
Brian has/had the callsign M3OSN so
you might as well forget him using them.
You might say, but the licence says different!
"..power supplied TO THE ANTENNA by a transmitter during.."
Note "to the antenna", not to the feeder, or at the output of the
transmitter.

Interesting.
No wonder Ofcom don't enforce the 10W limit - they can't be bothered
climbed onto roofs and towers to check the power at the aerial's input!
On HF, the feeder losses are usually fairly minimal.
Of course, some FLs may not have come across the subject of feeder loss
(or don't understand it). To be on the safe side, they assume that the
loss is much higher than it really is. To make absolutely sure that they
get their allotted 10W at the aerial feedpoint, they accidentally
over-estimate the amount that they have to crank up the transmitter
power to compensate for the loss..

I've given you _TWO_ pointers
Go do some work for yourself and find the info.
As an (ex?)Lead Instructor you should be more than
familiar with the first reference...
and since you wrote the second one you should be able
to find that one in less than 5 minutes.
But go ahead Brian... keeping prodding...
You'll need a Proctologist to get anything out of Paul by prodding!
The licence is very clear:
"..power supplied to the ANTENNA by a transmitter.."
Not to the feeder, and not out of the transmitter, but "to the antenna".

(a) dBW is the power level in dB relative to one Watt.
(b) Peak envelope power is the average power supplied to the antenna by
a transmitter during one radio frequency cycle at the crest of the
modulation envelope taken under normal operating conditions.
(c) Effective radiated power (e.r.p.) (in a given direction) is the
product of the power supplied to the antenna and its gain relative to a
half-wave dipole in a given direction."
From (c), it's obvious that "the power supplied to the antenna by a

And confirmed by that.
Son is in the police and he has told me what questions and how they ask
them to hang the guilty.
In my real ale pub, an ex business man says, when stopped by them, say
nothing and shrug your shoulders to all questions and they are quite
likely to let you go.

What happens if you've a stack of 4 antennas ? 400W to each ? or 400W
to the splitter ?
I think the antenna should include the feeder. Well it will encourage
you to get your feeder losses down.

Let's face it, the power limitation to the FL was only added
to provide the minimum of differentiation from a real licence
If only operating when there is an R in the month had been enough
to satisfy the Freebanders, it would have been that.

Jeff
You might think that but....
A very good question none the less; the Licence does not define where
the antenna starts, but it is certainly not 400W to each in a stack of 4!!
I guess that I one were being pedantic you could discount the losses in
the splitter and cables and calculate the actual power applied to each
beam and divide by 400W by 4.

which is what another post from m3osn was on about.
m3osn also used the phrase TO THE ANTENNA back in 2003.
allowing for losses in the transmission line allows an M3
to shove X watts in and only apply Y watts to the antenna.
