  1. Ultrasonic frequencies are not transmitted by voice mode radios such as GMRS. The available bandwidth severely limits both the audio frequencies that can be carried as well as the data rate. Any Ribbit transmissions will be right in the most audible frequencies that humans hear. Ribbit transmits using the audio frequency range of 500 Hz to 2500 Hz.
  2. My friend’s Baofeng UV5R transmits at just slightly more than 5 watts as measured by an MFJ UHF power meter.
  3. I’ve never heard of coax being cooked at low wattage. I don’t think that’s what happened. But it certainly might have gotten damaged in a way that allows a short or open. Try another piece of coax.
  4. @marcspaz Assuming the repeater had been established for some time, folks using a channel that’s known to be in use by a repeater is a bit like fly fishing directly beneath a dam. Sooner or later the dam will spill.
  5. Alright, I’ll give it a rest.
  6. Here’s the official regs: https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-E I will try to list the different types of stations but I apologize for missing any: Base Station, Control Station, Fixed Station, Mobile Station, Portable Station, Repeater Station. Unless regulated specifically, Portable Stations are a subset of Mobile Stations. Handhelds are simply a type of Portable Stations. There are a very few regulations that apply to handhelds to the exclusion of other station types. This forum has a long and possibly inconclusive discussion about Fixed Stations.
  7. If you read the regulations you’ll find references to several different types of stations.
  8. If you click on where it says “quote” at the bottom of the post you’re replying to, you won’t need to copy and paste and put quotation marks around it. It’ll automatically put it in a nice box.
  9. Elapsed time between when something was certified by FCC and the time it shows up in the list you looked at.
  10. That sometimes happens (at least I recall it happening once before.) It doesn't necessarily mean it's not legit. Might just be a lag.
  11. Capacitive coupling is only for the AC of RF. Capacitors block DC. No DC ground for your antenna is needed. However, poor electrical connections between body parts can be a cause of noise so people frequently bond body parts together with copper braids.
  12. If you choose Tone, only the transmit tone is important. Your radio will let all transmissions it receives through, regardless of the tone or lack of tone. If you change it to Tone Squelch, then your radio will only reproduce the audio from radios that exactly match the tone. I recommend not using Tone Squelch until you have a better understanding of how it works. Your transmissions still must match the input tone required by the repeater.
  13. What does that mean? Please don’t make me look to see what fun I’m missing.
  14. Here’s a lengthy thread about it:
  15. Welcome to the club!
  16. He has five posts and the last four of them are this kind of rubbish.
  17. Sometimes it’s just really easy to determine which whacko to put on the ignore list.
  18. First, a caveat. I don’t have the GMRS version of the UV5R. I have the regular old one. Does the GMRS version automatically do the repeater offset or do you need to include a 5 MHz offset in the column marked offset, like you did for Ranchino?
  19. The electrical ground through the cable shield is sufficient. None of the magnetic NMO mounts require you to scrape to bare metal.
  20. Why? Because features that are not supposed to be there are sometimes not there?
  21. Without knowing more about it I can only speculate, but the distance alone wouldn’t prevent it. So you are transmitting on 467.675 MHz with a tone of 141.3 Hz? The reason I usually suggest that people listen without a tone is because then you hear everything on 462.675 MHz. First, make sure you can hear the repeater. If you can’t, it doesn’t matter if the repeater hears you. Once you know you can hear the repeater then try transmitting. Feel free to ask if anyone hears you. Most people are friendly.
  22. MTS2000? http://www.batteryuniverse.com/two-way-radio/motorola/mts2000/btexc450sf-motorola-mts2000-radio-antenna?utm_source=google&utm_medium=cpc&adpos=&scid=scplp9-24541-BTEXC450SF&sc_intid=9-24541-BTEXC450SF&gbraid=0AAAAAD8Yjy-XpLrRokYZeHm-DIBekxYoi&gclid=Cj0KCQjw06-oBhC6ARIsAGuzdw2eJxZ-NWjBRWo_Q2E7B6fhTM1hPKpF4ybW7kSdZSVdZmotJ_Hs-1UaAlYWEALw_wcB
  23. It’s also the origin of another word. Nero shortened the guy’s fingers because he had been impolite. The Latin word for short is “corto”. From that comes our word “courteous”, which that stubby fingered fella was afterwards.
  24. But the good news is it might only have eight repeater channels to memorize.
