    Very certain it was roadrunner. It's kind of distinctive.

    I have noticed the same while working at the Norwegian Embassy compound. Particularly when the VP was on the move. When the big black vehicle motorcade was in motion, nothing with an antenna seemed to function.

    I agree, it's not like DMR If someone doesn't live in the same town as you, a code plug is not likely to be particularly useful.

    Antenna polarization Input modulation

    Mostly but not completely so. A radio that wastes a lot of RF on off-frequency harmonics is not putting that energy on the center frequency. 97% of your RF on center frequency or 79% on center frequency? Granted, 50% is sufficient at normal/close ranges.

    Can you explain why you say this?

    There is made in China and there is CHEAP made in China.

    One of my regrets is not having met Bob since he only lived a few miles from me. APRS.fi domain suffix is fi because Bob's family is from Finland and he was obviously proud of the fact. The English equivalent of Bruninga is Burns. Farther on to the APRS location idea, even with regular ham APRS, you would have to be within range of a receiver. If one is outside of cell coverage, you would also likely be outside of APRS receivers. Paired location data legal GMRS radios would have to be within regular simplex range and would offer no particular advantage other than battery life for the radio sending the data.

    Another example of line of sight being more important than distance ... on 70cm (GMRS is the adjacent 65cm band), I have heard a station 250 miles away on a regular basis when I plan on listening. I don't know exactly what their antenna is, but I know their radio has a maximum of 25 watts transmit output.

    The million dollar question, Dr Brothers, is "Who will you talk to?"
  11. AdmiralCochrane
    Distance doesn't matter if there is line of sight. I hit a repeater 17 miles away as well as one 5 miles away because the 17 mile away antenna has a GREAT location.

    The one you are thinking of is not so much Baofeng use as it is SHTF combat radio strategy.

    The antenna should have its own ground rod to avoid the length to the house ground rod. You want any problem with the antenna to get to the earth as soon as possible and not travel around Robin Hood's Barn to get there.

    As an amateur musician I always remember A=440 No trick or treaters on the busy highway I live on, too dangerous.

    Lack of available RAM

    I've never made a simplex greater than 12 miles. I guess all my radios are garbage.

    There may be a local or regional group on Facebook that can help you.

    Voltage vs amperage doesn't matter, it's the wattage/heat. That is the primary reason you can (almost always) get away with it for short transmit cycles. I don't recall a damaged final that appeared to have pure breakdown due to overvoltage. Also pretty sure if it was voltage that mattered, there would be more instantaneous damage vs damage over time (heat buildup).

    And Marine and Air band and MURS and VHF Business band and railroad band and ... and ... and ...

    Not sure it is the sun. Doesn't look like it is doing much today. I look at several solar activity sites every day.

    Both are good radios for their price. UV-5 is the best place to start and decide whether you want to spend any more money
  22. AdmiralCochrane
    On the other hand, I feel that the previous Kenwood TH6A's speaker is tinny. Listening to it is like learning to understand a fairly thick accent, where the UV5-R's speaker is much more natural. The Kenwood definitely has better receive filtering and probably puts (almost) all its RF on frequency rather than splattering it around on harmonics. 6 to 10 times the price to put a Kenwood in your hand. I own 2 of both.
  23. AdmiralCochrane
    I had the same experience with a fairly expensive radio with pretty good filtering. I was only 200 - 300 feet from a local dispatch repeater. Apparently first harmonic of their UHF frequency was right in GMRS.
  24. AdmiralCochrane
    I didn't know there were waterproof mobiles. Handy for open vehicles like Jeeps I guess
  25. AdmiralCochrane
    I have not had 2 way UHF transmissions via ducting, but have had 2 way ducting VHF transmissions between Long Island and central Maryland
