1016.5 | how to become a ham | LEDS::HUGHES | Dave Hughes (LEDS::HUGHES) NKS-1/E3 291-7214 | Wed Oct 21 1987 11:04 | 83 |
| Here's some more info on becoming a ham.
As has been said, you need a Technician or higher class license
to operate on 6 meters (50-54 MHz).
The requirements for a Technician class license are 5 words per
minute Morse code, elementary theory and regulations, and general-level
theory and regulations (known as Elements 2 and 3A). The Novice
license also requires 5 wpm and Element 2.
Under new FCC rules, the tests are given by Volunteer Examiners.
Each exam for Technician and higher is administered by a team of
three accredited Volunteer Examiners. These examiners must hold
Extra or Advanced Class licenses. You need an FCC form 610 which
is the application form. There is no charge for the exams or license.
They must be accredited through a Volunteer Exam Coordinator.
Additional information about VE's can be obtained from the Amateur Radio
Relay League (ARRL), 225 Main Street, Newington CT 06111.
Telephone 203-666-1541. The ARRL also publishes lots of books and aids
for learning Morse code, theory, and regulations. They even have Morse
code computer programs for Commodore 64 and C 128 computers.
The FCC has made special provisions for ham R/C. Here is an excerpt from
the FCC regulations:
"Section 97.99 Stations used only for radio control of remote model
craft and vehicles.
"An amateur radio station in radio control operation with a mean
output power not exceeding one watt may, when used for the control
of a remote model craft or vehicle, be operated under the special
provisions of this section, provided that a writing indicating the
station call sign and the licensee's name and address is affixed
to the transmitter.
(a) Station identification is not required for transmission directed
only to a remote model craft or vehicle.
(b) Transmissions containing only control signals directed only
to a remote model craft or vehicle are not considered to be codes
or ciphers in the context of the meaning of section 97.117." [codes
and ciphers are prohibited on all ham frequencies]
As was mentioned before, the eight channels on the 53 MHz band are
not reserved for R/C, but are available for use by any ham who wants
to use them. The newer channels on the 50 MHz band are also not
reserved for R/C, but there is a "band plan" that, while not carrying
the weight of law, has developed over time among 6-meter operators.
The band plan lists 50.800-50.980 as Radio Control (R/C), 10 channels
with 20kHz spacing. The same band plan lists 52.000-54.000 as used
for FM repeaters and simplex (note that 53.1 - 53.8 are right in
the middle there!). Also note that none of those channels are
designated as aircraft-only or surface-only.
While I have had no problems with 6 meter usage, it is wise to check
with local R/C hams who will know whether there may be a repeater
on the channel you want to use!
R/C operation is legal on any ham band. R/C radio manufacturers
have only made their equipment available on 53 MHz (and soon 50
MHz), because the AMA has designated specific frequencies in those
bands as "sanctioned" channels. Hams are allowed to construct their
own radio gear, and could operate on other bands (but probably would
not be allowed in AMA events, unfortunately).
An interesting twist for future interest: The Novice license
now allow all modes of operation on 222.1-223.91 MHz and 1270-1295
MHz. I would like to see some hams do some more experimentation
in those bands. The antenna might only have to be a few inches long!
By the way, I got all of this info from "The FCC Rule Book - A Guide
to the FCC Regulations" published by the ARRL.
One last piece of data about radios. I use Airtronics gear, and
the CS7P-AM radio is the only one they have 6 meter modules for.
The good news is that if you buy a new radio set and send it to
them unused, they will retrofit it for 6 meters for no charge (except
the shipping charge back to you). I just got that done to my 2nd
radio I recent bought from Sheldon's. Airtronics has promised a
new line of radios "coming soon" that will also be available on
6 meters.

1016.1 | What about 51 and 53 mhz?? | CSC32::M_ANTRY | | Fri Oct 07 1988 10:11 | 7 |

Ok, Now I got the radio pegged what about 51 and 53 mhz, whats their
future????
Pager shift? I dont know either but I wear this thing on my belt
and they give me money. I think it may be DEC human resource
expeirement.

There is no restriction for 1991 on 51 or 53 Mhz. These are
radio amateur bands and fall under different restrictions (such
as having a license, etc) and are 100 kc spacing so the narrow
bandwidth does not mean much. However, Please check your local
area to make sure there are no repeaters etc. on the frequency
you select.

1016.3 | new ham channels are narrow band | CHGV04::KAPLOW | Set the WAYBACK machine for 1982 | Sun Oct 09 1988 12:42 | 13 |
| The 53 MHz frequencies ARE wide spaced, so even old gear should
work fine there. The "new" HAM channels, 00-09 are in the 50 MHZ
(not 51) area, and are narrow band just like the 72/75 MHz
channels. The 53MHz band does have some 6 meter repeaters, as
close as 10KHz offf the RC channels, so beware of neighbors up
there.
The new 50 MHz channels SHOULD be clear of other users like
repeaters, but also remember that this is by ARRL band plan, not
FCC mandate. You can do whatever you want wherever you feel like
as far as the FCC is concerned, if you have the license.

1016.4 | Ok 50 Mhz it shall be | CSC32::M_ANTRY | | Mon Oct 10 1988 11:49 | 10 |
| I read that buy a 50 MHZ if you are going to buy one. I have heard
al's mention that a 6 meter repeater was possibly causing some
interfearence at the Scale masters. Ok. I think it will be a
Airtronics MD7SP on a 50 MHZ channel for the Larry Jolly Pantera
that should be here soon.
Thanks for all the help.

1016.6 | Sounds bad to me! | CTHULU::YERAZUNIS | I have become Death, the Shatterer of Worlds. | Wed Dec 21 1988 17:46 | 8 |
| Will the old 27xxx and 53xxx frequencies still be available in 1991?
Or is the hobby destined for extinction ? (and no, I have absolutely
no confidence that a "1991" radio will be safe to fly from a personal
hazard point of view in any urban area. Those pager transmitters
are typically active for ten seconds per page, and put out upwards
of 200 watts. That's instant death for anything except cars and
possibly close-to-shore, slow-speed boats. )

1016.7 | 6 METER OPERATION | SALEM::COLBY | KEN | Thu Dec 22 1988 08:33 | 15 |
|
Ref .46 and -.1
The 50 and 53 Mhz bands are only legal if you own a Radio Amateur
license. It also does note preclude you getting clobbered on
these bands, since a 6 meter station can be operated on any of the
frequencies that RC is operated on. It is not against the law,
just a gentleman's agreement that the hams do not operate at these
frequencies.

1016.8 | a lively topic | LEDS::HUGHES | Dave Hughes (LEDS::HUGHES) NKS1-1/E3 291-7214 | Fri Mar 10 1989 09:23 | 81 |

It's hard to keep up with you guys! I have a couple (long) comments:
re: Ham frequencies - The ham bands are reserved for ham use only (note
the word BANDS, which is a contiguous range of frequencies, not a set of
channels). They are the exclusive, primary users of those bands, as
opposed to the 72 MHz where modellers are secondary users. That's the
good news. The only direct interference possible is with other hams. The
bad news is that there is no law prohibiting any hams from operating on
ANY of the old OR NEW R/C channels in the ham bands. The old channels in
53MHz range have no special meaning to hams. The new channels in the 50
MHz range do have a bit of meaning - AMA got ARRL (the ham equivalent
national organization) to agree to list the 50MHz R/C channels in their
frequency usage plans, so they are RECOMMENDED for use by R/C, but there
is no law requiring hams to observe the ARRL usage plans. Fortunately,
few hams seem to be operating on those frequencies now.
Hams can operate R/C on ANY of the ham bands. The 6 meter frequencies
are those chosen by AMA (or AMA/ARRL) as recommended frequencies. The
AMA can prohibit hams who aren't using those channels from flying
in sanctioned competitions, but they can't prohibit them from flying
otherwise. It's unlikely any ham would put an R/C aircraft on any
of the bands below 6 meters, because of virtually guaranteed
interference, potentially from ham stations anywhere in the world.
Bands higher than 6 meters (like 220MHz) are very interesting, however.
I'd like to see some R/C development on higher frequencies.
Because the new 50MHz channels are 20kHz apart, any R/C ham operating
on those new frequencies needs narrow band equipment. The old 53MHz
channels are 100kHz apart, so narrow band is not and never will be
required there.
re: Use of odd channels - the FCC is constantly being asked for new
frequency allocations in a very crowded radio spectrum. Hams just lost
2MHz in their 220MHz band, despite intense lobbying from the ARRL and
even congressional (non-binding) resolutions made on behalf of hams.
That band was turned over for commercial use. This was done because not
many hams were using it. The FCC will not suffer any of the spectrum to
go unused for long.
If the AMA were to decide not to use the odd channels, the FCC would
eventually take them away and give them to other services who would
use them at higher power, and the result would be much worse than
R/Cers using the odd channels. That is why the AMA cannot back down
from the phase in plans for the odd channels.
Now, have a little pity on the AMA. I'm not real happy with the results,
and perhaps more competent people could have done better (any volunteer
radio experts out there willing to spend a lot of time for no
compensation on behalf of R/C modellers?) However, the FCC is the
authority who decided the channel separation, not AMA. FCC will not
waste spectrum on people who just want to continue using antiquated
radio equipment. The bottom line is that we have no choice at all -
old equipment will become obsolete and must be scrapped, period.
It may be possible to delay that a little, but it WILL happen. It's
not the AMA's fault, it's the FCC doing its job in responsible
management of the radio spectrum. I think you'd have a hard time
arguing your case to the FCC when a new, conforming radio can be
bought for around $100 today.
re: interference - once again, the demand of modellers for cheap
equipment will result in high losses in crashed airplanes. As has been
said, the transmitter is easy, the receiver is hard. Interference is
guaranteed, and the only ways to help are to make the receivers better,
and local channel management by local clubs who will have to get a lot
smarter about use of radio frequencies in their area. This is where we
can and should lobby the AMA to set up a technical department capable of
providing detailed technical advice in radio management.
Well, I've gotten myself going again and could continue, but I'll stop
here. It will get sorted out eventually, but it will be 5 years before
it's pretty well under control, I believe. The louder the cheapskates
yell to preserve their old equipment (most of them arguing some sort of
principle, rather than really not being able to afford a new radio), the
more grief we'll all have in getting the problem sorted out and managed.
Meanwhile, I'm happy that I can sit on my ham channels and wait for the
smoke to clear. My next new radio (which may be a while) will be a new
narrow band rig on the 50 MHz channels, after I have made sure they're
not used by any ham repeaters in the area.
