New Ham/10 meter questions

[K1OIK]

Wrong.

K1OIK thinks he's very clever, and was deliberately trying to obfuscate by alluding to the fact that SSB is sometimes considered a form of AM because, basically, aamplitude is modulated. But the "AM" setting on your radio is NOT SSB and is not allowed for Techs on 10m.

I am not that clever. SSB is not a form of AM .

I know general class license holders who can't really answer the question about the different modes and they are not recently licensed. The op could have and unfortunately should have just Googled the net to get the answer to his questions. When I read it I guessed the second or third post would be an insult to the op. Even if you thought the original question about the different modes was something the op should have known you could have just kept it to yourself but no a few of you decided to play "let's insult the new tech". Of course some people say stuff on QRZ they would never have the courage to say to someones face. It is what I call Internet courage.

OIK:

Technically, SSB is a form of amplitude modulation that is processed to basically eliminate one sideband and the carrier. However, most people think of AM as actually being double-sideband carrier present emission. There are several of the older transmitters that actually transmit single-sideband with carrier in the "AM" position.

Then there is ACSB (Amplitude Companded Side Band) which uses a scheme which double compresses a single-sideband of the signal and transmits a reduced "pilot" carrier which allows for the receiver to "lock on" to the signal.


MAL:

The ARRL "band plan" is incorrect! If you look at the frequency chart which they also have ( http://www.arrl.org/files/file/Regul...ands_color.pdf ) you will see that for Technician Class licensees the 28.300 MHz to 28.500 MHz segment is indicated by a yellow line which corresponds to SSB only. That is correct! No matter what the ARRL says, they are NOT the definitive source for information. The regulations concerning the Amateur Radio Service are contained in 47 CFR Part 97 and every amateur radio operator needs to be very familiar with those regulations.

Yep I am incorrect. When I sit and read the actual FCC laws and jump around I find a little footnote on a subsection that talks about "phone emissions J3E and R3E. ". I then had to go and learn what the heck J3E/R3E means which is SSB. Many of the sites I was referencing didn't take this extra step and just say "Phone".

My mistake.
Why can't the government make laws that non-lawyers can understand?

MAL:

Many of the Members of Congress are lawyers and, of course, they have to write laws that require a lawyer to interpret. The Federal agencies follow suit and a lot of their employees are lawyers. The result is regulations that require a LOT of study to interpret.

That's true, but if there is a repeater maybe that will provide some additional incentive to upgrade!

As a Technician he cannot use FM on 10m or go to the high end of the band where the repeaters are.

MAL:

To compound the situation, there was one of the major Japanese radio manufacturers, I don't recall just which one right now, that was publishing a chart, similar to the ARRL chart, on the various modes allowed by each class of amateur radio operator's license, that they were distributing at events all over the United States. Unfortunately, there were several errors on that chart and, if those allocations were actually followed by certain lower class licensees, the operation would definitely be in violation of 47 CFR Part 97.

Fortunately, the manufacturer eventually ran out of those charts and they are no longer being distributed. However, there are probably some of those charts in use by a few amateur radio operator.

I understand that a lot of General class and higher dont believe that the Tech class should be allowed 10 Meter Privledges. I know my limitations as far as the band plans go. Maybe I misworded my question. I was wanting to know the reasons for there being 4 modes in such a little band. Thanks for the answers that were posted in a kind manner. And for those who were condensending well... you have to start somewhere. Excuse for asking a question!

Yes, I think you were misunderstood.

10 meters is a huge band compared to the rest of our HF allocations, at 1.7 MHz. wide. That's also why you can run higher speed, wider digital modes, and 16F3 'wide' FM on portions of it.

However, the most popular modes are CW near the low end of the band, SSB starting at 28.3, AM around 29 MHz., and FM at the high end of the band - 29.3-29.7. LSB is normally not used on 10, but there are reasons it might be useful to have on this radio. Some satellites are 'inverting', so if you transmit up to the satellite on one sideband, it comes out as the other, and we usually want to hear USB coming down from the bird, so you must use LSB to transmit up to it. There are no 10 meter to VHF or UHF satellites in operation now, but there could be.

Since Techs are allowed both USB and LSB (with LSB not normally being used on this band), it's too bad they can't use DSB suppressed carrier, which is basically both LSB and USB at the same time. DSB is more efficient than AM, and very easy to generate, compared to SSB.

To the new op: Yes you should grow a thick skin to survive the QRZ crowd, and you should also do some basic reading.

I have been a HAM since April. I just recently got a Radio Shack HTX-10 10 Meter Rig. I Built my own inverted V Dipole. The radio has 4 different modes FM, AM, USB, and LSB. My question is what is the difference between the 4. And what is most of the traffic on.

Remember what my old friend Paul Goldberg said, "You hams just ain't kosher!"
