  1. SHEESH! Ever used Wikipedia or even done a search about Rosa Parks. You are obfuscating your lack of performing research and fact verification just like a prominent political candidate campaigning for relection.
  2. Rosa Parks was sitting in seats marked for "colored" and not in seats for "whites." She refused to move from her seat when a white couldn't find another seat. Now, if you are going to make statements about historic events you need to verify your facts first.
  3. A VNA can be purchased for around $75 that will give you all the information you would get from a dedicated antenna analyzer costing over $300.
  4. Have you made any contact with a local ham club? Antenna tuners are pretty common equipment for hams.
  5. Many antennas come with cutting guides, just remember to check and measure twice before cutting. You really need an antenna analyzer to tell you where the antenna is tuned before making any changes. An SWR meter isn't an analyzer.
  6. That's not correct. When transmitting in DMR both time slots are sent so the entire 12.5/25 kHz channel is used even if it is carrying only one timeslot.
  7. Personally, I would look more towards MURS for trail use rather than GMRS. MURS, being VHF vice UHF, will have better penetration in wooded areas and follows the earth curvature better than GMRS. 2 watts on MURS will give you about the same coverage as 5W on GMRS.
  8. I use this on my amateur radios, not the GMRS ones.
  9. WX is on the radios, set to activate if an alert is received.
  10. How deep are your pockets? Can you afford over $1000.00 for the antenna, mast, and coax feedline?
  11. If they are not cognizant of what's already installed in their area and are interfering with an existing repeater then yes, they are being irresponsible.
  12. IMO it would be against the regulations to key the transmitter without knowing the output frequency. It could have been set to use a licensed frequency where you would then be an unauthorized transmitter and/or possibly interfere with a current user of the frequency.
  13. As a former frequency coordinator, I have to say "depends." Most of the coordination plots use the Longley-Rice algorithm and the predicted coverage area between wide and narrow band remains the same in most cases. Some coverage areas do increase while some decrease, the change being about 3%. As to the performance of a radio at the fringe of the coverage, it again depends on both the radio's specifications and any change to the coverage shift if any,
  14. There is always static on any radio frequency. You set squelch to raise the receive threshold so any stronger signal will open the receiver to listen. Monitor disables the squelch setting.
  15. Pink antennas always work as chick magnets (and longer is better).
  16. Boofwangs and other similar units are referred to as CCSDs (Cheap Chinese Spy Devices) and I own 6.
  17. Air always works as long as the pressure isn't too high. For canned air, keep the nozzle at least 6 inches away from the part being cleaned.
  18. Try this one: Super-Elastic Signal Stalk — Signal Stuff
  19. It sounds like hog wash to me.
  20. Using code words or phrases in normal conversations would be against the regulations as has been clearly stated. However, in an actual emergency you can pretty much throw the regulations in the trash. The key point being the FCC, should they investigate, would have to agree the situation did rise to the level of a true emergency and agree the use was justified.
  21. I use the mantra High In, Low Out when dealing with repeaters.
  22. There are several amateur radios that will use a Bluetooth headset or microphone available but, I'm not aware of any such radios made for the GMRS market.
  23. There are a lot of electronic products, including RF amps that either do not have or have counterfeit FCC approvals.
