  3. From the album: Misc. Radio Gear

    I did a bit of a detailed gain analysis of the antenna system I wanted to install on my CX-5. I ultimately went for the “C” installation. The goal was to see the tradeoffs using different antenna mounts and cable types and lengths. I had to settle for a longer lead in cable length than I had originally wanted but the hit on the gain wasn't too bad. The analysis was done using the older higher gain antenna, CA-2x4MB, which isn't manufactured any more but my old one still works and I have a new one still in the plastic bag. I had purchased two at the time, one to install and the second as a spare. I also have the Diamond SG7500, but its not as broad banded as the old antenna. The Comet CA-2x4SR would have worked provided I had a good ground plane. Since I'm using the luggage rack mount I'm stuck using a no ground plane design type so this antenna is out for the moment. https://forums.mygmrs.com/gallery/image/282-ca-2x4mb-scansjpg/?browse=1 https://diamondantenna.net/sg7500a.html https://diamondantenna.net/c213sma.html https://diamondantenna.net/c110.html
  4. I don’t really see any either because I normally disable JavaScript. I use a script blocker on Firefox and on the iPhone there is an option to turn it off on Safari too. This also does a good job killing annoying ads on other sites too. They also load faster on mobile devices and cuts down on your data usage.
  5. Interesting. I wonder if there are any rules specifically about how ID’s must be done on digital systems. I'm assuming you’re referring to repeaters exclusively, doing the CWID in analog. The question was about subscriber units, user radios, when using a repeater or in simplex mode. In my case, likely not in general, the CWID feature is only available when using NXDN on the Kenwood radios I have. For example the ND-1300, current production radio, when the NXDN version is selected in the programming software the manual CWID TX feature is available. However selecting the DMR version it’s not. I’m trying to find out is there a rule or technical reason why that’s the case. So far I haven’t found anything definitive.
  6. And one wonders why it's getting worse?
  7. That makes sense. You wouldn't want to run "narrow band" NXDN on a FCC licensed "very narrow band" frequency. I would like to know if there are any really solid technical reasons why CW ID isn't done on DMR and P25. I just wild guessed what it could be in the prior posts. I am likely wrong, but have to start somewhere.
  8. I've read that ID'ing on Part 90 is regularly ignored. I guess the FCC doesn't care that much about their own rule. I wasn't aware of the specific emission designation for CW ID on NXDN. Thanks.
  9. I was wondering the exact same thing. My NX-1300's allow CW ID function in NXDN mode but not in DMR mode. Just a wild guess on my part but I'm thinking it has to do with the TDMA nature of DMR. The radio has to kill the time slot selection, i.e. no time slots, and use straight FM to send the ID. If that was done on a repeater what happens to the other conversation on the other time slot? It gets hosed too? With NXDN I suspect it's rather trivial to switch to FM to send the ID since there is no time slot to muck things up. You only have one conversation to worry about on a repeater channel. The issue with P25 is with the newer Phase-2 mode which uses TDMA, just like DMR. And the same comments about DMR I think would apply.
  10. It's not even a required test element for any class of amateur license anymore.
  11. While the CW ID transmit isn't done on a timer, the function has to be assigned to a front panel key, it has to be manually selected each time to send. The one FM digital radio I have has the CW TX function built into the radio. The radio is also Part 95 certified too in case someone wants to know. https://forums.mygmrs.com/gallery/image/251-nx-300jpg/?context=new
  12. When they figured out the money stream would dry up after the market reached saturation with Win10 they had to obsolete it and force people to upgrade again. Then there is the required hardware issue crap too. I installed Win10 on an old AMD dual core PC because Kenwood blocked supporting their license manager app, KPT-300LMC on anything older. The only thing I need it for is install feature licenses to the few NX-1300 radios I own. The programming software for those radios is hacked so I don't need the license manager to activate it. All the other radio software I have works fine on Win7 Pro. I'm going to move all that to Win10. The win10 system was installed using an "activator" app. I'm not blowing money on a license for Win10 now when Microsoft is going to EOL it next year. https://learn.microsoft.com/en-us/lifecycle/products/windows-10-home-and-pro
  13. This project is worth keeping an eye on it. Still not ready for prime time but it's getting closer. https://reactos.org/# And if you're thinking about dumping Windows for Linux but still need to run Windows software then this project might be of interest to you. https://www.winehq.org/
  14. Let him try it first on his car and using his radio.
  15. The title of this thread could be interpreted another way. One could ask does the user care a lot about how much they spend on a radio? I know some on this forum have likely spent well past 4 figures on a portable radio. If I spent that much on a portable radio I would be reluctant to even take it out of the house. I have only purchased a few radios new over the years. The majority are clean used radios showing few signs of use. Even then I've spent maybe $200 to $250 at most on a used commercial grade radio. The more expensive used commercial ones tend to be FM/Digital types. Out of the later the FM/P25 radios seem to be noticeably more expensive than the other FM/digital types, especially the VHF models. Ham gear is a different story. Before the new TH-D75A was released the older discontinued TH-D74A was selling for a huge price premium above what they sold for new. I saw a few selling for above $1000+ on eBay. When the TH-D74A's were available one could buy it new for around $650.
  16. The US auto manufactures made that mistake decades ago. They still haven't recovered.
  17. This is true for anything. Some engineers here feel a bit too smug. Same goes for what school they graduate from as well.
  18. And at times money. Oh well, its a hobby.
  19. I was at my typical Thursday night radio coffee group get together last night. One of the guys had a good setup for a ground plane for a mobile antenna mounted on the rack behind the truck cab. I took a couple of photos to share on the group here. Might give a few people some ideas to try out.
  20. Those radios were a source of cheap gear for Ham uses.
  21. The purpose of government isn't to make things more efficient. It's to waste more tax payer money and hire more public sector employees.
  22. With the software tools commonly available fake paper documents can be easily created too. With the now "Deep Fake" technology you can't even believe videos any more.
  23. Maybe you don’t, but it does seem to be a popular topic on this forum.
