  1. VoLTE on FirstNet is unusual. Not to say nonexistent (BeOn), but unusual. FirstNet is primarily a data service. My experience with LTE has been very poor - consumer-grade junk that sacrifices coverage for data speeds and falls down even in populated areas. For essential communications, we use encrypted LMR, and the SWCRS system when longer range is required. WQVS960 has done an outstanding job building that system. I understand the desire to record traffic, but forcing repeater operation without provision for contingencies is negligence no matter what the justification. Radio inhibit commands keep the unit from working at all, not just on the system.
  2. Private company charges for use of its equipment! News at 11! You're not entitled to use somebody else's repeater, and it's quite reasonable to ask for money to offset construction and maintenance expenses. Sites aren't free, you know.
  3. If they do not, that illustrates serious negligence on the part of that agency. No reason to not have their own simplex freqs as well as the various 7TAC interop freqs programmed.
  4. That's definitely worse performance than I would expect. From inside a second-floor apartment to another portable outdoors, two miles simplex is easy with a good antenna (I use a Smiley Super Stick IV). I'm sure we could go further if desired as RSSI is excellent when using the Smiley. The path is across a mixture of urban and suburbs, with a couple farm fields thrown in for good measure. I'll grant that we're both using public-safety-grade radios with double-conversion superhet receivers. I'm not familiar with the architecture of the KG-905G so you could have a receiver overload situation if it's a direct-conversion/SoC deal. Have you repeated the test with the stock antennas? Better antennas have been known to cause overload when used on radios with poor selectivity. As stated before, excessive objects between the two stations will also impact range.
  5. Personally, I wouldn't stress too much about simplex frequency selection. 446-447 MHz is generally accepted for UHF simplex so I'd program in some frequencies in that range. In the exceedingly unlikely case you encounter analog activity on one, just move to another. We use TG1, NAC 293, and Digital Squelch (EFJ's term for it...), on P25 simplex. It's functionally identical to CSQ. Unfortunately, KPG-D1NK has an awful reputation for being clunky and slow. It's not like the older spreadsheet-based Kenwood software. I have an NX-200K and like it pretty well. It's not something I'd use for mission-critical (antenna orientation and lack of channel selector lockout) but for business, amateur, and scanning, it's a good unit. I particularly like the depth of options permitted by the menu system, including on-the-fly audio setting changes. They're now cheaper than TK-2180s despite being far more full-featured radios. If you purchase an NX-200, shoot me a PM. I have some manuals that will help you get the unit set up and performing at its best.
  6. To be entirely honest, I just use 446.000 for P25 simplex. I have never heard anyone on 446.000 aside from a few friends (and a simplex repeater I stumbled across in southwestern Colorado). 146.52 either, for that matter. FM simplex is dead here.

    Assuming this is a previously good radio that stopped working without a programming change being made, take it to your radio shop for alignment.
  8. I'm not aware of any direct 3.5mm audio accessories. I use a speaker mic and a cord between the mic and headsets; it works well enough.
  9. A couple weeks ago, but yes. I purchased it from Cahaba Valley FD.
  10. I recently picked up an NX-200K for 2m. It's a nice radio; I prefer police/military radios like the EFJ5100 and Motorola's XTS series but am happy with that little Kenwood. Being limited to a 16-channel scan list (the NX-200/300 can scan the whole radio if you'd like...) isn't the end of the world. Around me I have two (soon to be three) GMRS repeaters, two 70cm repeaters, and a couple simplex frequencies that I scan. On VHF, there's three 2m repeaters, 146.52, the county's common LE dispatch, fire dispatch, and ambulance dispatch. 16 is more than enough.
  11. No, I just use the OEM whip antenna. I might swap it out for a stubby to keep it from getting snagged as much, this is a short-range Capacity Plus system and squeezing out every last drop of portable performance just isn't necessary.
  12. I'll vouch for the durability of the XPR7550e. I carry one as my work radio and it's gone through some pretty awful abuse with nary an issue. I really couldn't ask for better durability, the thing has been doused with abrasive slurry, blasted with high-pressure hoses, banged around on vehicles and equipment, and subjected to high in-vehicle temperatures for days on end. As much as I criticize MSI, they still have engineers who can design a great hardware package (other than overly-sensitive PTTs and channel knobs). Audio quality is another matter entirely. It completely falls apart to the point of unintelligibility in high-noise environments even with noise suppression enabled. Generally, P25 radios are built with fire service in mind and have better noise cancellation than other offerings, which is a point in favor of P25 in my opinion. A 5100ES blows a 7550e away when used next to a filter press or non-muffled air-cooled diesel engine at full throttle.
  13. Mixed-mode operation is a neat feature. I'm going to be pitching replacing an analog Part 90 repeater near me with a Quantar programmed for mixed-mode. Should improve its usefulness.
  14. Welcome to the forum! I think you'll find GMRS to be both useful and enjoyable.
  15. Oh, I've got some interesting ones here: - Arizona DPS TK-390s - TK-190s found while salvaging a sand mine and given to me - EFJ 5300ESs from an Army TRS with intact trunking programming (somebody messed up...) - EFJ 5100ESs also from an Army TRS, acquired third-hand from a guy who bought them as surplus - UHF HT600 discarded by a contractor - Low band MT500s from Big Stone NWR in Minnesota (given to me by a friend in Arizona - no clue how they found their way down here...) Plus a variety of other radios retired from EMS, fire, business, and local LE service.
  16. Not entirely accurate, a radio can listen to repeater outputs (usually in conventional scan) without affiliating to the system assuming the traffic is in the clear. I do that to listen to a 700 MHz high site near me. To answer the original question, P25 for me for the same reason as KB2ZTX. The other and primary reason is that I hold a Part 90 license for my side business and P25 is the most cost-effective route to AES encryption in a non-Chinese radio. MSI's refusal to sell AES TRBO equipment in NA cost them a customer.
  17. The repeater is not your property, therefore you do not have the right to utilize it without permission from its owner. Simple as that.
  18. The 5 MHz spacing is an offset for duplex repeaters.
  19. My first is a Kenwood TK-390. My current primary portable is an EF Johnson 5100ES.
  20. They're not common, but you can find them. EF Johnson and Harris are the main ones. My 5300ES mobiles have "Made in Texas, USA" printed on the bottom.
  21. If I remember correctly, there was a shakeup with the exact section of Part 95 with the rules change in 2017.
  22. You can define a list of up to 16 PL tones when programming the radio, which can then be selected from the front panel.
  23. Hard to go wrong with a Kenwood TK-390, TK-380, or TK-3180. All are 4W and Part 95 type-accepted.
  24. They're far, far better radios than anything Midland or BTECH sell, sold, or will sell for the foreseeable future. WRAK968 is about right as far as pricing...880s are a commodity, nothing more.
