I'm running a homebuilt transmitter. LSB seems to work for me because
I'm not running the transmitting in stereo. I think you might need some
better filters on the AM transmitter.

You need some more common sense in between the ears, Brother of
Morkl.

Todd is not my brother

I have a borther and like many we don't esp get along

I doubt that there is ANYone who has ever known you for long that
got along with you, Morkie. You're an arrogant putz that makes it easy
to not be liked.

Transmitting on illegal frequencies with an illegal transceiver?
Only stupid Toad would do that.

Gather around the legal frequencies this evening at 14.331 as we get
a forum of LEGAL Hams together to discuss the nefarious activities of
Toad and Roger. Look for this forum to begin on or about nine p.m.
eastern time. Toad cannot join in, nor can KB9RQZ, since they are not
licensed for this freq. Roger needs no invitation...he will lurk and
jam as he sees fit.

Before you go around spouting that I'm running illegal, I would
suggestion that you read Part 15 (47 CFR 15) but more to the point 47
CFR 15.225

How much power you running? Unable to hear you here, but I'll give a
listen again tomorrow if you're still up and running.



10000uV/m at 30m is the maximum. How much power into an isotropic
radiator give 10000uV/m at 30m. Of course, when the antenna has gain,
power has to be reduced to avoid illegal operation.

My guess is 3 mW.

The level is the same as emissions within the CB band:


Sec. 15.227 Operation within the band 26.96-27.28 MHz.

(a) The field strength of any emission within this band shall not exceed
10,000 microvolts/meter at 3 meters. The emission limit in this paragraph is
based on measurement instrumentation employing an average detector. The
provisions in Sec. 15.35 for limiting peak emissions apply.
. . .

The amount of power applied to an isotropic radiator which will generate
10,000 uV/m at 3 meters is 30 microwatts. This assumes that the 3 meter
distance is in the far field, or that it's measured in the far field and
extrapolated to 3 meters as though 3 meters were in the far field, which
is the method and assumption used by the FCC.

A simple dipole reduces the permissible power to about 23 uW, and ground
reflections will typically nearly double the field strength, so a safe
power level would be about 6 microwatts into a dipole antenna over
ground for someone interested in conforming to the regulations.

Hey, Roy -

My 3 mW answer was for 30 meters. I think that ratios correctly to your 30
microwatts at 3 meters. Yes?

Yep, that's right. And I finally got curious enough to look up the
actual regulation. According to section 15.225(a), intentional radiators
at 13.553-13.567 MHz are allowed 15,848 uV/m at 30 meters, which is
about 4.75 mW to an isotropic antenna in free space. There's also a
0.01% frequency stability requirement which would imply crystal control.
And any emissions extending outside the band have to be about 54 dB
lower, 30 uV/m at 30 m.

So if N9OGL's transmitions are legal power wise, he would basically be
broadcasting for the kids across the street. Maybe he could take song
requests. They can just shout out their front doors what songs they want
him to play.

I can copy perhaps 8 beacons on 13.555 MHz from all across the U.S.
Assuming they too are running the power level Roy calculated, N9OGL's beacon
should also be copyable.

Not true.
I have an AM "beacon" running some test groups smack dab
in the middle of the HiFer/ISM 22M allocation. At maximum power
I am at the legal limit. Most of my tests are -20dB from that level and
I
have copied my "becaon" from over 100 miles away twice. I was -6dB
down from max, and was rather shocked. Don't rule out the odd fluke
path.

If you ever hear a YL reading a set of word pairs each followed by
a ID nubmber in cut morse, that is my odd little station.

I normally keep the power -63dB down from max legal, and only boast
it while actually conducting tests.
