    duckduck got a reaction from ZGPilot1955 in BAOFENG UV-9R PRO vs. UV-5R   
    I bought a UV-9R PRO for my son because it was cheap and advertised as fairly waterproof. It has a different sort of a belt clip that uses a plastic "button" that is screwed onto the back of the unit that slides into a separate belt clip. First, the button screw came unscrewed. Then after Locktite-ing the screw, the plastic "button" broke off and now this unit is useless to me. At least it was cheap...
    The more I send out radios with my son to run around with his friends with, the more I like the original UV-5R:
    cheap small light flexible antenna sturdy clip takes a lickin' and keeps on tickin' did I mention that it's cheap?

    Seattle area has a pretty good amount of repeaters already. I don't know that we need MORE repeaters. Expanding coverage area into the boonies? Sure.
    I don't really have a practical usage scenario for GMRS other than talking to Jr when he rides his bicycle over to his friends' houses. GMRS would be nice to use if the power goes out and the generator at the local cell tower runs out of go-juice.
    I would love to see city/county/states put up some high quality GMRS repeaters covering major metro areas. I would also like a pony and a fairy godmother.
    Repeater hardware isn't cheap. Seems like a possible way forward is to create a GMRS club and get everyone to put in some money to build a club repeater. Let's see, if you have 20 club members, and they each pitch in $200 ...hmmm. Maybe rob a bank?

    * Note to the humor impaired: I do not support bank robbery as a way to fund GMRS repeater construction.

    Wow!  That's actually really neat... but I personally wouldn't spend that much. 
    The platform is only 17' high.  The shooting rail is the part that is at 20', and the rail doesn't look like it would hold much weight.  You will almost double your range on flat terrain, but we are talking about going from 3.1 miles to 5.9 miles.
    I bought this instead....

    I get about a 9 to 10 mile radius (in flat/level terrain) with my antenna on this.  A tripod, ground stakes and guy lines, I spent less than $280.   I designed it to be portable, but it can be a permanent setup with zero concerns...  in fact, right now and for the past 3-4 months, it's actually behind my house in the woods being used to hold up my 80 meter HF antenna.

    I would say that having to pay for shipping or a restocking fee to get a refund on a defective product would also be a reason. Even having to pay shipping to get a defective product repaired would be sufficient reason to do so.
    In these cases, the purchaser was not provided with the product they paid for. It should not be incumbent upon them to pay anything for the repairs or to get the repairs made. It is incumbent upon the vendor to provide the (working) product that the customer paid for, and no customer should have to pay extra to get it. If the customer is not provided with the product they were promised at the agreed upon price (without added costs), then it is the responsibility of the vendor to make it right (at no added expense to the customer).
    If Bridgecom is making customers pay anything extra just to get the product they were promised in the first place, they need to be reported. The BBB would be a good place to start. Perhaps the District Attorney (or a Consumer Affairs Bureau) in their jurisdiction would be another place to report them. Filing a dispute with the credit card company is another way to begin to resolve this issue. Posting unsatisfactory reviews on Yelp or Google is a way to warn others, and it may get their attention to where they reach out to resolve the matter. Finally, and especially if unable to resolve the matter in a satisfactory way, posting on forums such as this is helpful for others that may be considering doing business with that company.
    I'm sorry to hear that there are companies out there that would engage in such wormy business tactics, but I know they exist.
    Unfortunately, it's a sad reality.

    duckduck reacted to WRAM370 in BTECH GMRS 20V2 radio   
    This appears to be a rebranded Anysecu WP-9900, which is a dual band radio 136-174/400-480 mHz.
    I imagine this Baofeng Tech model has different firmware in order to restrict transmit to the GMRS channels.
    I bought an Anysecu WP-9900 for $129. It is ok, but it does not have the front end rejection of better quality radios. What this means is that it is subject to interference as you drive around, and go by LED billboards and signs, etc.
    The audio from the speakermic is a bit weak when running at highway speeds. I got this for my wife’s car, which is a newer 2020 model, and it can be mounted under the seat. But if it was in my Xterra, which is running aggressive 33” tires, I imagine it would be very difficult to hear the audio from the speakermic at highway speeds, due to the interior noise from the tires.
    So I am not condemning this radio, but you could have full transmit capabilities for $20 less, if you are inclined to do that sort of thing.

    duckduck reacted to Radioguy7268 in XPR 7550e ... just wow...   
    Motorola does an ALT process (Accelerated Life Test) where they automate certain functions like turning the radio on & off repeated times quite rapidly, changing channels, pressing the PTT button, along with repeated drops from a 4ft height onto a hard surface. This is supposed to simulate 5 years of typical use within a short testing time frame.
     
    https://www.youtube.com/watch?v=Y_ScXS4mrvY
    This isn't exclusive to Motorola - other manufacturers have similar testing procedures. Any radio with Mil-Spec ratings probably went through similar testing.
     
    I am not disputing your experience (and a replacement XPR housing from Motorola is quite expensive!), but I am saying that the radio is designed to survive a typical drop - and I've got stories of units that dropped 30 ft. down an elevator shaft onto concrete and survived. I even have one story about an old SP10 plastic chassis radio that went through an asphalt plant, emerged looking like a bent black banana, but still would transmit & receive! I've also seen some units that appeared to be almost brand new on the outside, but were totally crushed inside - and the customer swore they didn't run over it with a dump truck.

    now lets talk about the losses in Db and how much power that is.

    3.5                        56
    4.0                        60

    all of the above loss specs are manufacture specs, I strongly suggest that you measure your line loss w/watt meter if possible to know exactly what you are getting at the antenna.
    IME most of the book specs are on the money for hard line ,RG8/213 can be a crap shoot depending on manufacturer. I've had some really bad and some pretty good.
    LMR I've had a love/hate relationship w/, good cable but seems to be prone to moisture issues. wish I had pic of the 7yr old cable that pretty much self destructed.
    hope this is of some help to those looking to put up a machine or control station in the future.

    duckduck reacted to Lscott in Power supply for base station.   
    I would recommend a LFP, Lithium Iron Phosphate, battery pack over a cheap Lead Acid type.
    https://www.bioennopower.com/collections/12v-series-lifepo4-batteries
    Lead Acid batteries, gell, glass matt, marine etc. all suffer from the same short comings. 
    First they don’t like sitting for extended time periods in a partial state of charge. When they discharge lead sulfate forms on the plates. Newly formed its porous allowing the acid to penetrate so on charge it is changed back to lead or lead dioxide, depending on which plate it is like the positive or negative one. Allowed to sit the porosity decreases and the areas where the acid can’t penetrate results in a permanent loss of capacity. The common practice of using a trickle charger is employed to combat this.
    The next problem is the terminal voltage during discharge. It starts off around 12.6 volts and drops fairly steadily as the battery discharges. Mobile radios are typically designed to operate on a 13.8 volt electrical system, which is what you have when the car’s alternator is charging the battery. The range is usually plus or minus 15 percent of that 13.8 volts, so the low side is around 11.73 volts. That’s about 50 percent, more or less depending on discharge rate, of the battery’s capacity used.
    http://scubaengineer.com/documents/lead_acid_battery_charging_graphs.pdf
    At the low voltage spec radios may behave erratically, shut down and or loose significant output power.
    LFP batteries largely avoid the above problems. You can leave them sit around for months in a partial state of charge without damage. The terminal voltage starts out around 13.3 to 13.4 volts and remains around 13 volts for 70 to 80 percent of the discharge capacity. That makes for a better match to the typical specifications for mobile radio gear.
    https://footprinthero.com/lifepo4-battery-voltage-charts
     
    The LFP batteries are significantly lighter than similar capacity Lead Acid types. Much better for backpacking etc.
    Now the major negative of LFP battery packs is the cost.

    As a matter of practice I spend time hunting down all the relevant documentation, in PDF format, for any radios I have or plan on buying.  I have a library of folders for each radio/model series with user guides, service manuals, notes, FCC grants, modifications if any and manufactures brochures. The last one is the first thing I look for when thinking about purchasing a used radio. Excellent source for features, exact frequency ranges, on UHF it's common to have more that one, number of memory channels etc. If I don't like what I see then I've saved myself some money by not getting something I won't like or can't use.

    Without access to a repeater you can still get good use out of your GMRS radio of you talk friends and family into using GMRS as well.  It is great for outings, hiking, camping, amusement parks, road trips, etc.. (terrain dependent).

    duckduck reacted to WRQV528 in CHIRP: Useful CSVs   
    After recently programming a ham radio with a few sets of frequencies for listening, as it came with none pre-programmed, I decided to export the sets I made and post them here to save others the duplicate effort. Just download these files, then from CHIRP go to "File > Import".
     
    A few things to keep in mind:
    These files use Windows/CRLF line endings (hopefully this never makes a difference). I don't condone transmitting on these frequencies on with a ham radio (especially on the weather radio frequencies as they are for public safety), but am providing relevant notes should you dare do so. On this note, CHIRP does not export or import the "Power" column, so be sure to set power levels manually as noted (should you dare use a UV-5R on, e.g., GMRS). In a similar vein to 2.1., the "Comment" section you will see when importing describes settings you may have to set manually.  
    I hope you find these helpful!
     
    I have only been able to test these files with several Baofeng models: UV-5G, UV-9G, UV-5R+, and UV-5RTP. Regardless of make and model, please let me know if you run into any issues.
     
     
     
    GMRS Channels
    gmrsChans_20220706TZ.csv
    Taken from a Baofeng UV-9G's defaults with tweaked names.
    NOTES:
    Channels 1–7 should be set to no more than 5W. Channels 8–14 to should be set to no more than 0.5W.  
    Business Channels (UHF, Motorola CLS Series Enumeration)
    motoCLSBizChans_20220707TZ.csv
    Taken from the manual for the Motorola CLS1110 and CLS1410. This channel numbering scheme of 56 frequencies is used by several business radios, such as the aforementioned Motorola models, Advantage AWR series, and to my vague knowledge, some Kenwood and Midland business radios.
    NOTES:
    All channels should be set to no more than 1W.  
    Business Channels (UHF, Motorola CLP Series Enumeration)
    motoCLPBizChans_20220707TZ.csv
    Taken from the manual for the Motorola CLP series. This channel numbering scheme of 90 frequencies is a superset of that used by the Motorola CLS series.
    NOTES:
    All channels should be set to no more than 1W.  
    Weather Radio Frequencies (in order of allocation)
    wxAllocs_20220707TZ.csv
     
    Weather radio frequencies, with the first 7 numbered in the order in which they were allocated over the decades ("WX" order). This differs from, and includes more frequencies than, the numbering scheme used by most weather alert radios made since the early '00s; these tend to use the main 7 channels in ascending frequencies, available below.
    NOTES:
    Never transmit on these frequencies. These are for public safety (especially during severe weather events and other natural or man-made hazards). If you cannot disable transmitting on these frequencies on your radio(s), set power to the lowest setting possible to mitigate an accidental transmit should it occur. I have disabled scanning on these channels because weather radio stations operate 24/7/365.  
    Weather Radio Channels (the main 7 in order of ascending frequencies)
    wxChans_20220706TZ.csv
    The 7 main weather radio frequencies, numbered in the order of ascending frequency ("Channel" order). I believe this channel order is mandated for weather radios wishing to be Public Alert™ certified. This differs from the numbering scheme used by many weather alert radios made before the early '00s, many handheld radios, and many handheld transceivers; these tend to use the "WX order", available above. 162.000MHz, 163.275MHz, and the 161MHz frequencies are omitted because they are not official weather radio channels in the United States (nor part of the Public Alert™ standard to my knowledge).

    Midland's "Extra" FRS Channels
    midlandExtraChans_20220706TZ.csv
    Based off-of a table on RadioReference's wiki. Channels 23-36 tested against a Midland T77A and confirmed working; channels 37-50 do not exist on this model so those are untested.
     
    MURS Channels
    mursChans_20220715TZ.csv
     
    Based off-of the text for Part 95J.
    NOTES:
    Make sure your radio's bandwidth does not exceed MURS' odd (with respect to GMRS) maximum bandwidths. For a Baofeng UV-5R, this means you can only transmit on MURS channels 4 and 5, and you must do this on narrowband mode. All channels should be set to no more than 2W. Keep in mind FM is not the only transmission mode allowed on MURS. (MURS is weird.)  
     
     
    Changelog (dates and times in UTC):
    2022-07-06:
    Added Midland's "Extra" FRS channels (only channels 23-36 have been tested and confirmed working as the only radio I could test against was a T77A). Added MURS channels. Populated the comment field in all rows of all files. These contain information on bandwidth and max TXP (transmit power), and other relevant information (bascially each row's respective "NOTES" bit). 2022-07-07:
    Introduced a set of business frequencies used by the Motorola CLP series, which is a superset of those found on the CLS series. Renamed the original business channel set from "bizChans" to "motoCLSBizChans". Removed redundant set of asterisks from "wxAllocs" for WX01. 2022-07-15:
    MURS channels 4 and 5 shared the same Location column value in the CSV, causing channel 4 to be ignored. Fixed.
