How can one figure out what one's grid square is, given lat/long? location maidenhead-locator I see that many contests, awards, and other items, use Grid Squares as a means to identify where one is. How can one convert from Lat/Long to Grid Square? What are its advantages over newer voice or data communication modes? modes cw I'm trying to program my Baofeng bf-f8hp with the chirp software, but as I have to do, "Download From Radio", after I choose the appropriate maker, product and model, all I get is an error. receiver fm equipment-operation icom weatherīF-F8HP: "Radio did not respond" when trying to use CHIRP For example listening to WX-01 (162.550 MHz), no problem. but NOT when using the built-in WX stations. What's interesting, is that this happens in MR and VFO modes. Why does the audio on my FM transceiver cut out every 5.5 seconds? What's the advantage to a 5/8 wavelength vertical? Why 5/8 in particular, and not something. What makes a 5/8 wavelength vertical desirable?Īn ordinary 1/4 wavelength vertical is smaller and resonant without any loading coil or matching network. If I want to cut a half wavelength segment of coax for the two-meter band and the velocity factor is 85%, is my cable going to be shorter or longer than a meter? Is a 1/2-wave coax cable shorter or longer than the full-speed 1/2-wavelength? coaxial-cable impedance-matching antenna-tuner If I have a short inductor-loaded vertical antenna that I have not carefully matched to 50 ohm. Ignoring the possibility of multiple radiators and phasing harness(es), consider the following example: Amateur Radio Stack Exchange Community Digestĭoes a halfwave (or multiple) length of coax duplicate the load impedance of one end at the other end?
