Subject: [QCWA] Baluns part 12
Message-ID: <504709A0.5070406@att.net>

Materials...

Not all ferrites are created equal.

For broad band operation, a lower permeability is
required. 250 works well (Type 61)

Larger permeability works, but is best suited for
low band operation. (type 43 for example, works
well from 160-40 meters.)

Core size is important. The larger cores, such as
FT-240 (2.4" OD) will support up to a KW or two.
Smaller cores like FT-120 (1.25" OD) should be
limited to 100 watts or so.

Surprisingly enough, #16 AWG lamp (or Zip) cord
is fairly close to 150 ohms Zo, so it is a very easy
choice for making 9:1 baluns with. A lot easier to
deal with that winding with #16 AWG magnet wire
and having to maintain the correct spacing every
turn.

Hoever, even twisted together, two enamled wires
are close to 80 Ohms Zo, so your best bet for 1:1
baluns is using RG-58 on a toroid or slipping a LOT
of ferrite beads around RG-8.

Hey OT's -- Does the QSO party really begin on Friday at 1 p.m. (CDST)?  
Or is this a day too soon?

Message-ID: <505123AC.8070608@att.net>

Here's a list of "clear channel" stations (although now they
ARE shared channels) but still the predominant stations on
given frequencies on the AM band.

<http://www.oldradio.com/archives/stations/ccs.htm>

I was searching the FCC data base for who else is on 660 AM
along with KTNN, The Navajo Nation in Window Rock AZ, near
Gallup NM.

They are roughly 720 miles from Ranger TX. Unfortunately,
and almost in a straight line behind me, is KSKY in Balch, TX
about 130 miles from me.

So much for trying to listen to KTNN at night. ;-)
Good thing they have an internet stream.

Oh, incase you wanna poke around the AM broadcast band

    NARC,

    Hopefully, non-controversial, except for the Amelia Earhart controversy itself!  This site has a lot of technical information about the radios, frequencies, FRC/FCC/ITU frequency and assignments, harmonics, harmonic output powers, post-loss-reception reports, antennas, receiver specs, etc. involved.  
      http://tighar.org/Projects/Earhart/Archives/Research/ResearchPapers/Brandenburg/signalcatalog.html">http://tighar.org/Projects/Earhart/Archives/Research/ResearchPapers/Brandenburg/signalcatalog.html


    An excerpt:



    "... In October 1930, the FRC[2] re-designated 278 kHz as the ?airport frequency? and expanded its mandated use for ground station transmissions to include all aircraft, not just itinerants.

    In December 1931, the FRC[3] revised the national aircraft calling and working frequency from 3106 kHz to 3105 kHz.

    In May 1937, the Federal Communications Commission, successor to the FRC, issued revised regulations[4] allowing all aircraft to use 6210 kHz as a day-only alternate for 3105 kHz. The revised regulations also: defined a ground station transmitting on 278 kHz as an ?airport station;? required such stations to maintain a continuous listening watch on 3105 kHz; and restricted the allowed power on 278 kHz, thus limiting communications with aircraft to short distances ? about 30 miles.

    Other nations using 6210 kHz[5] (A3) were: Canada, for aircraft use; the Soviet Union for interior communications; and Venezuela, for broadcasting. 3105 kHz also was used by Canadian aircraft flying the route[6] between Vancouver and Seattle."



    Scroll to the bottom of that page and click on any of the other technical pages to see each area.  One of those pages goes into analyzing the non-harmonic-surpressed output of their transmitter and tries to calculate the power output on those (up to 5th) harmonics.

    All for fun, and the technical aspects of this enduring mystery.
