    That is the repeater NSEA (North Shore Emergency Association) uses during the Evanston 4th of July Parade and evening fireworks. It's a shame that the parade has been cancelled for the past two years. Hopefully it will resume next year! 

    I got a call last night letting me know that they are planning to resume the Dayton (Xenia) Hamvention next year. I've missed volunteering as a 'golf cart driver' for the event.

    I use LMR400 on my repeater for the main run and the shorter patch-cables.. Contrary to what all the experts claimed, it works just fine, and more than good enough for my non-life-critical application..
     

    That is absolutely true for the first X number of years. Eventually though, it will break down and generate a lot of snap-crackle-pop noise in both the receiver and transmitter.

    Quick question....If wide band is better, why did they ever make these radios narrow band? (I don't know the difference, really, but I know my MXT275 has trouble communicating with wideband radios.

    Narrowbanding was mandated by the FCC to allow for increasing the number of frequency channels available.

    The problem for GMRS users is that virtually all of the existing repeaters are using wideband "legacy" equipment.

    The key phrase here is "FTDI" which is a chip, manufactured by Prolific, inside the head of the USB portion of the cable, that converts serial signals from the HT to USB for the computer to use.

    Actually, FTDI and Prolific are totally different in how they implement the USB to UART function.  FTDI chips have a unique id which allows them to always create the same COMnn irrespective of which USB one chooses to use. Axorlov has already covered the Prolific foibles.

    I read the entire 'blog' and frankly, something doesn't add up. He claims that they are manufactured to his specifications, but then he has to hand assemble the parts apparently using some kind of adhesive? Then places them in a C-clamp for 24 hours to 'cure?'

    Each one is carefully sanded to remove any bumps or edges. Each adapter is then tested by a Motorola service tech on his Aeroflex at a cost of $125/hr for each of three portable radios?

    Then he's selling them for only $25? Something just doesn't smell right.

    I did find a stud to bnc adapter several years ago, but found I'd need to use a grinder to pare down part of the shoulder collar to allow the adapter to fully screw into the radio's antenna port. I gave it up as a lost cause... ?

    Why would an actor have several EE's working for him anyway?

  13. Can Non-Licensed Friends Transmit Legally on a GMRS Licensee's Radio?

    since gmrs doesn't have the same prohibition on business use

    Only businesses that were licensed when such was offered by the FCC would have that ability. The FCC hasn't licensed GMRS for businesses for a very long time (since 1989 IIRC).

    The only legal way a business could use GMRS now would be for every employee to have their own GMRS license.

    Must be PEARL, no? Before the ARPANET and in the same sentence with C... and F...-IV, let not these names be uttered after dark.

    No, Perl is not to be confused with PEARL.

    Quote

    Though Perl is not officially an acronym,[11] there are various backronyms in use, including "Practical Extraction and Reporting Language".[12] Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier.[

    Actually I took SNOBOL4 the next semester.  SNOBOL4 pattern-matching uses a backtracking algorithm similar to that used in the logic programming language Prolog, which provides pattern-like constructs via DCGs. This algorithm makes it easier to use SNOBOL as a logic programming language than is the case for most languages.

    SNOBOL stores variables, strings and data structures in a single garbage-collected heap.

    A simple example: 

              OUTPUT = "What is your name?"
          Username = INPUT
          Username "J"                                             :S(LOVE)
          Username "K"                                             :S(HATE)
MEH       OUTPUT = "Hi, " Username                                 :(END)
LOVE      OUTPUT = "How nice to meet you, " Username               :(END)
HATE      OUTPUT = "Oh. It's you, " Username
END

    Yuck. I remember I had to take a programming class in COBOL for my computer science degree. At least the school had a VAX cluster by then with terminals. You could even dial in from home and log into your account to do your programming projects.

    Back in the Dark Ages (long before even ARPANET!), I took COBOL, FORTRAN IV, and PERL during the same semester. The same professor taught all three classes. For our major project in each class he essentially gave us the same task, which basically was a simple accounting application for a golf course.

    I decided to combine all three assignments into a single solution: PERL for the input/output routines, COBOL for the database, and FORTRAN IV for all maths operations. The professor was only mildly amused, but he did finally give me a 4.0 for all three classes. ?

    EDIT: I don't remember the exact number now, but as close as I can recall this took close to 4 thousand punch cards!
