  1. Are these the radios your title mentions? 2 watts out, ten GMRS channels? https://www.wirelesspro.com/motadira.html
  2. That’s exactly how I understand it as well. The entire configuration and the use thereof establishes the station type. With that in mind, I could have a radio in my transceiver in my house (Fixed location) that I use to communicate directly with other base stations or mobile/portable radios. That’s a Base Station. Then, I could change channels and use it to communicate through a repeater to mobile/portable radios and it becomes a Control Station. However, if I only use it to communicate to Fixed Stations then my station is a Fixed Station and I must restrict my output power to 15 watts. The upside is that my Fixed Station and the other Fixed Stations are able to use the 467 MHz Main channels that are otherwise limited to transmissions to a repeater or brief test transmissions.
  3. Where are those terms (Fixed Base and Fixed Base 2) defined within part 95?
  4. 1. There is no privacy. PL tones don’t work that way. Anyone with a receiver capable of receiving on the GMRS frequencies can hear any nearby transmissions. 2. The repeater channels receive using the same frequencies as channels 15-22, so congestion will follow you.
  5. So, that would seem to imply that the type of station is fluid and defined by usage. A person could simply change channels and the station would transition from a base station to a control station. Is that your understanding?
  6. The regulations establish four set of channels with different rules for output power and bandwidth. The software might use groups internally to manage how the radio complies with those rules. Or it might leave those gaps so you can add channels that have different tones within each group. It’s your radio, if you want to put all the channels under one group and if the software allows it, it’s your choice.
  7. What kind of response are you expecting? Are you saying anything or are you just clicking the PTT(kerchunking)? The normal response to kerchunking is to ignore it. If you’re asking for someone to verify they can hear you then it depends on whether someone is listening at the time and whether they are inclined to talk.
  8. This! The directions clearly state that the default squelch is 04. @WSBP830, I really suspect that when the display says S9, it really is saying Sq, but the LCD character is the same for a 9 or a lower case Q, and the next step should be to press the LOCK button, then use the volume up and down buttons to adjust the squelch. The squelch Level is not indicated as S9, or S1, S2, S3, etc. It’s indicated as 01 - 09, but not until you push the LOCK button after navigating to the Sq menu.
  9. That’s a nice gift. Here’s a place that carried it before it was discontinued and it looks like they have connectors. https://www.anixter.com/en_ec/products/FXL-540-NHR/COMMSCOPE-ANDREW-SOLUTIONS/Coaxial-Cable/p/438625 Here’s the data sheet:
  10. Welcome @WSBN871!
  11. Yes. The frequencies of the channels are established in regulation: § 95.1763 GMRS channels. The GMRS is allotted 30 channels—16 main channels and 14 interstitial channels. GMRS stations may transmit on any of the channels as indicated below. (a) 462 MHz main channels. Only mobile, hand-held portable, repeater, base and fixed stations may transmit on these 8 channels. The channel center frequencies are: 462.5500, 462.5750, 462.6000, 462.6250, 462.6500, 462.6750, 462.7000, and 462.7250 MHz. (b) 462 MHz interstitial channels. Only mobile, hand-held portable and base stations may transmit on these 7 channels. The channel center frequencies are: 462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, and 462.7125 MHz. (c) 467 MHz main channels. Only mobile, hand-held portable, control and fixed stations may transmit on these 8 channels. Mobile, hand-held portable and control stations may transmit on these channels only when communicating through a repeater station or making brief test transmissions in accordance with § 95.319(c). The channel center frequencies are: 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000, and 467.7250 MHz. (d) 467 MHz interstitial channels. Only hand-held portable units may transmit on these 7 channels. The channel center frequencies are: 467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, and 467.7125 MHz.
  12. Here’s a simple little site that answers the question. Just type a ham or GMRS call sign into it and it will display both licenses if they have one. https://gmrs.app
  13. Then you probably should contact Midland.
  14. Lossy cable will make an antenna’s SWR appear better than it actually is. An SWR meter in the radio or connected next to the radio measures the forward power before it has been attenuated by the cable and measures the reflected power after it has been attenuated twice, making the ratio of reflected power to forward power much lower than it actually is.
  15. It’s not entirely true. The difference between a tuned antenna and a badly tuned antenna is audible. Preliminary manual tuning using a trans-match is done while listening.
  16. Are you sure that the second character in S9 isn’t just the way the LCD displays a lower case ”q”? Here are the instructions: To adjust the Squelch Sensitivity: 1. Press the Menu button to place the radio in “Menu” mode. 2. Use the Volume Up or Volume Down button to scroll through the menu options until the LCD display shows Sq. 3. Press the Lock button to confirm your selection 4. Use the Volume Up or Volume Down button to scroll forward or back- ward to select the desired squelch level, from 01 to 09. ▪ The default squelch setting is 04, which generally provides reliable squelch operation for most applications. 5. When the desired squelch level is shown on the LCD display, press the Lock button to confirm your selection. YOU MUST PRESS THE LOCK BUTTON TO CONFIRM YOUR SELECTION OR THE SQUELCH SENSITIVITY WILL NOT BE CHANGED.
  17. That’s just not true. An antenna has no idea whether AM or FM is flowing through its elements. Now if you really meant that an antenna tuned for VHF FM broadcast band is not ideal for AM broadcast band at 550-1600 kHz, I would agree.
  18. https://www.gigaparts.com/yaesu-ft-65r-5w-vhf-uhf-handheld-transceiver.html
  19. It’s the same thing. I was just in a hurry.
  20. I have the FT-65, FT-4, VX-6, VX-7, and FT5DR. The one I use most frequently is the FT-65. But $140 is a stupid high price. The most versatile and durable of my radios are the VX models and the FT5DR. I haven’t used them as much as the FT-65, but I intend to work on that. Get prices from Gigaparts, HRO, or DXEngineering. Gigaparts has the FT65 for $95.
  21. Yes, that sounds right.
  22. Exactly right!
  23. I am not sure either. The only difference I can think of is that a true Base Station probably would have a base station antenna, which could be hundreds of feet in the air and reach a hundred miles. Two base stations talking to each other through a repeater could span a pretty good distance.
  24. More than one person has argued over this. There’s an entire thread about it. You have to go back up to the Personal Radio Services and read the definition of Fixed Station. The differences boil down to this that Fixed Stations are fixed in location, AND only communicate with other Fixed Stations, AND are allowed to transmit on the 467 MHz frequencies (as well as the 462 frequencies) even though they are not talking to a repeater. Another curious thing about the rules is that where it lists the types of stations that may transmit on the 467 MHz Main frequencies through repeaters, Base Stations are not in the list.
  25. An offset of 5.0001 MHz would indeed be out of compliance, but that’s not what people are doing. The FCC established 30 specific frequencies, but not specific pairs that must be used with each other. As long as a person sets their repeater to receive on one of the established 467 MHz Main frequencies and transmit on one of the established 462 MHz Main frequencies, they’re legal, even if the difference isn’t exactly 5.000 MHz.
