- Seems odd to me why anyone would be prepared to pay for these. I have always
- considered calls to be part of the 'protocol overhead' of ham radio;
- they are a tiresome burden we have to accept in order to stay legal. In
- reality, they tend to get in the way of 'real communication'.
- Maybe someday we will be able to transmit our calls on some subcarrier or
- other, complying with the legal requirement to ID, but without needing to
- interrupt the data-flow to do so?

- Attention all AZDEN AZ-11, AZ-61, & AZ-21A Owners....I recently purchased a
- AZ-11 10 meter FM HT. I am pleased with the radio except for one thing.
-
- When using the radio on high power, the receiver takes about 1 second to
- fully recover after transmit. When using a local repeater where the signal
- is immediately present upon dekeying the transmitter, the signal will fade
- back up to a full quieting signal. This peculiar symptom does NOT occur when
- the unit is used on low power.
-
- The battery was fully charged during use of the radio. This particular
- quirk is somewhat annoying when using carrier squelch as opposed to tone
- squelch.
-
- Incidently, Azden does have a factory issued fix to cure a rf feedback
- problem which shows up as a receiver oscillation or "Belch" after dekeying the PTT button. This fix was performed on my unit.
-
- I would appreciate any feedback from AZDEN HT users on what your impressions
- are about this quirk and how your unit performs.

- Roy, when you ask, do you mean baud=baud for most and baud=
- subset of bps for others, or were you trying to say baud as
- in baudy or body ? Unh or did you mean the way LARC uses it
- instead of the way ARRL uses it ? Or is this a PC issue I
- missed while ready other threads?
-
- OBTW, according to the "Encyclopedia of Computer Science
- and Engineering", a baud is a unit of signaling speed and
- refers to the number of times the state of the line changes
- per second. It is the reciprocal of the h - in seconds-
- of the shortest element in the signaling code. By contrast,
- a bit is the smallest unit of information in a binary system.
- Therefore, the baud rate is equal to the bit rate only if
- each signal element represents one bit of information.
-
- it continues:
- Unfortunately, in much of today's literature, the terms
- "baud" and "bits per second" are used synonymously. This
- is correct in cases where pure two-state signaling is used,
- but is incorrect in general. For this reason, the term
- "baud" is gradually being replaced by "bits per second",
- since the latter is independent of the coding method used
- and truly represents the information rate.
-
- What a great book! And it shows why some 12 years ago or
- so I completely switched to use of bps instead of baud.
- Of course, I earned my living as a technical writer back
- then :-) Or to pull from another comm book on my shelf:
- "Non-technical people seem to use baud when they really

-
- A couple of the "X5" stations were identifying themselves as in
- the "Serbian Republic". I am deducing that these are
- stations in the Serbian-occupied part of Bosnia-Herzegovina which
- Serbian nationalists have declared a separate country; and they are
- either pirates, or more likely deciding to use their own prefix
- (either amongst themselves, or from some kind of local officials)
- to deliberately state to the world that they are no longer part of
- the nation of Bosnia-Herzegovina.
- .
- As far as I've heard, that prefix was not properly assigned to anyone
- in Bosnia; nor is there any international body that recognizes the
- legal authority of Serbian nationalists to either govern or issue
- operating permission on any of the territory of Bosnia-Herzegovina.
- The proper and legal prefix for B-H remains T9.
-
- If they are in Serbia proper, as far as I know X5 was never awarded
- properly to any part of Yugoslavia.
-
- Perhaps someone else has more information on this?

- First I would like to thank everyone that has sent information
- to me already. What started out as what I though to be a useful
- exercise has now become a very interesting problem. As with
- any interesting problems I need more data :-).
-
- To make the table useful to everyone I will need to know the
- rates for airmail for different zones (i.e. same continent
- vs. different continent). As an example Japan has three zones;
- the first for Asia the second for NA and the third for Eu.
- The rates for each zone are different.
-
- The next item is what will your postal system exchange for
- one IRC? Is it enough for airmail postage to anywhere in
- the world?
-
- The last item is how many QSLs can you mail for one unit of
- postage. The US's unit of postage is 1 oz which is good for
- several QSL cards (I will go to the post office today and
- check). This would be useful if you have several different
- cards going to the same manager.
-
- Once again thanks for all your input and I hope to have the

-
- CTCSS is the generic term for Continous Tone Coded Squelch System. This
- is a "subaudible" tone mechanism for controlling receiver squelch. The
- tones aren't really subaudible, being in the 50-150 Hz range, but most
- rigs have a low frequency response limit around 300 Hz, and some have
- specific filters to remove the tone from the output. Anyway, the presence
- of the proper tone on an incoming signal is detected by the CTCSS decoder
- and your receiver squelch is opened. The reason that this is preferred
- to ordinary carrier presence detection as squelch control is that the
- tone identifies the signal as a desired signal as opposed to channel
- crud. This is really important in metro areas where intermod can generate
- tons of crud in your receiver that prevent the carrier squelch from
- operating correctly. Many repeater systems require a CTCSS tone be
- present in order to access the repeater. And many repeaters also output
- a tone to make monitoring less painful. So encode and decode capability
- in a radio are very useful. Motorola calls the system by the trade name
- Private Line or PL, and GE called their system Channel Guard, or CG,
- but they're all the same thing.
-
- >What is DTMS squelch and DTMF paging?
-
- DTMF stands for Dual Tone Multi Access, the ordinary telephone
- touchtones, or TT, that are used for dialing a number. Nearly
- all amateur HTs have a TT pad and a few also have a TT decoder
- that will open the squelch on reception of a 3 digit TT sequence.
- This is DTMF paging. Also, most repeaters respond to TT commands
- for access to special features such as an autopatch interface to
- the telephone network.
-
- >What are the advantages/disadvantages to these options as I consider an HT?
-
- You will want CTCSS encode/decode capability for repeater access in many
- areas, and you'll want a TT pad to allow control of repeater functions.
- DTMF paging is less useful. Many repeaters automatically mute their output
- audio while receiving TT so paging through a repeater usually doesn't
- work. Paging via simplex should work, but it's an unusual way of operating.
-
- >Right now I seem to like the Kenwood TH-78A. Any other recommendations?
-
- I'll bite my tongue and avoid my usual anti-Kenwood tirade. :-)
- My preference is for the Yaseu HTs, particularly the FT-470,
- but Alinco, Icom, and Standard all have desirable units.
- Some of the characteristics you want to give high precedence
- are ruggedness, the Icom G series is champ but some of the others
- are good, battery life, the Yaesu save function is the most flexible,
- freedom from intermod, none really offer this but some are
- definitely better than others, a user friendly interface, the
- FT-470 really shines here, and a reasonable price, the Alinco
- is champ of the bottom dollar contest. The TH-78 doesn't
- win in any of these comparisons.
