  1. What I was referring to was a breakdown of the fine by model. It is very doubtful the FCC will assess the maximum amount allowed by law.
  2. I'll disagree with having to be a business to use LMR. There are specific requirements for who is eligible for a frequency listed in Part 90.20, the Public Safety allocation. The requirements for 90.35, B/ILT or the Commercial portion are the same as the requirements for GMRS. The allocation of frequencies is divided between coordinators representing specific industries, but you don't need to fall into one of those industries to have a frequency assigned.
  3. It'll be interesting to see the breakdown of the penalty. The Part 90 being on Part 95 will be telling.
  4. You are making generalizations you can't back up with actual measurements to claim the new WOXUN is a further example of a CCR. There are a number of Moto radios that fall in the same category of cheap Chinese radios as Moto's Schaumburg facility has been reduced to primarily office space. I don't think Moto even builds a radio in the US anymore.
  5. Here is the official calculator for antenna/tower height. Remember, it's tower height PLUS any part of the antenna above the tower for the total height. TOWAIR Determination (fcc.gov)
  6. You'll need to check the specs for your radio to be certain, but you'll need close to 600W to power the GMRS radio.
  7. If the transmitter is at the antenna along with the necessary power the the transmitter can be coupled with Bluetooth with the GMRS (or other service) transmitter sending the signal. What people are assuming is there needs to be coax involved. The transmitter is part of the antenna. Think cellular BDAs or WiFi range extender.
  8. Gravity hasn't stopped working as of yet. Turn it upside down and then insert the wire. Works every time for me.
  9. If you, or one of your children, can state you heard the conversation then call the local PD and talk to someone in their vice section. They will probably come ot and interview the people that heard the conversation and then take action. They will bring in Federal assistance from the FCC and possibly the FBI. The FCC involvement is unique in that they do not require a warrant to inspect a building looking for radio equipment.
  10. Not directly if your intent is to provide Internet. You need a modem and that limits speed. Then you run up against the reporting requirement along with the limits of your radio's duty cycle.
  11. Personally, I think you are way over engineered. I would look at other supplies such as some of the inexpensive Chinese ones. I'm running a 30A no name that's designed for communications work and paid less than $25 for it. If you want a good Chinese one, look to Mean Well. Their supplies are a little more than what I paid but have a great rep. My little cheapie has millivolts of ripple, so little I can't measure it accurately with my cheap Harbor Freight meter.
  12. Download CHIRP and use it to program your radio. You'll need a programming cable but CHIRP lays all the fields out in a spreadsheet so it is an easy task. The Miklor website has both the links and instructions to make the job easier. www.miklor.com
  13. 100W at 12vDC is 5A of current and it is probably a little more than 1/3 of your transmit draw. Your batteries should recover the drawdown from 1 minute of transmit time in about 4 minutes with your panels putting out the full wattage.
  14. If you don't need the meters, this is the model without them. https://www.toboaenergy.com/product/samlex-sec1235-switching-power-supply/?_vsrefdom=adwords&msclkid=7e73c0b058a31f4ec5f49f244919dfc7&utm_source=bing&utm_medium=cpc&utm_campaign=**LP%20Shopping%20-%20Electrical%20Switches&utm_term=4582352148614327&utm_content=woocommerce_gdf_12563%20%7C%20Samlex%2030%20Amp%20120vAC-13.8vDC%20Switching%20Power%20Supply%20%7C%20%24156.8 If you don't need the 100A capacity, you may like this: https://www.toboaenergy.com/product/samlex-bbm-1225-battery-back-up-1224v-25amp-charger/
  15. The in-vehicle repeaters are useful for extending the range of a hand-held and little more. It's what public safety does with them.
  16. Depends on the type of license. For GMRS a license covers the immediate family only.
  17. Morse, while being the "first digital transmissions" is not prohibited as long as the signal sent by the radio is still FM.
  18. Save yourself the grief of trying to tune a dual band antenna and purchase a GMRS antenna. https://www.amazon.com/Laird-Technologies-450-470-Quarterwave-Antenna/dp/B0079555WM/ref=sr_1_5?dchild=1&keywords=laird+antenna&qid=1602764409&sr=8-5 will attach to your existing NMO base.
  19. Fusing the leads gives you protection against a failure that could result in fire.
  20. This supply will meet all your needs. You can buy an inexpensive multimeter at Harbor Freight and have enough left over to get your antenna. https://www.amazon.com/dp/B082TTY3L7/ref=sspa_dk_detail_0?pd_rd_i=B082TN889J&pd_rd_w=aAnjW&pf_rd_p=7d37a48b-2b1a-4373-8c1a-bdcc5da66be9&pd_rd_wg=U3xPt&pf_rd_r=8TN3JZQQQ83GBPR3PBNR&pd_rd_r=c136a1c9-166b-4c81-9433-d7c27f808772&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExODlPQVdDQ1JLTVJLJmVuY3J5cHRlZElkPUEwMTQzNzQ4MTRSRUcxUFNTWUM0QSZlbmNyeXB0ZWRBZElkPUEwMzYzOTU0MkQ3NjJFRDdCWllBQSZ3aWRnZXROYW1lPXNwX2RldGFpbCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU&th=1
  21. You have many options for a power supply. Get one that outputs between 12 and 15 VDC, 13.8VDC being ideal. Most allow the voltage to be adjusted so you will need a meter. The amperage should be at least 10% greater than the transmit draw of your radio. In watts, that's volts times amps. For an antenna, I would look at a J-pole or one that doesn't need a ground plane for use in your apartment. Once you get in your house, whatever you can both afford and get away with. With radio, height is king so you need your antenna as high as possible as it directly affects the range you will have.
  22. I'm bowing out of this discussion so let it be said we agree to disagree.
  23. From my experience dealing with both the WTB and PSHS is they have no issues with applying rules and restrictions from one section or part to another in their interpretations of a particular rule. It is virtually impossible for laymen, such as ourselves, be aware of all the past filings and rules touching on any aspect of equipment certification or rule applicability. We may have the means, but lack the training, of searching the record for any discussion, petition, rule or interpretation that may be given in any discussion regarding how we view the applicability of one section of the rules to our discussion. The interpretation of the rules regarding equipment certifications and modifications to the stated operating parameters of equipment are best left to the Commission. The rules explicitly tell what is and isn't permissible. Changes to those permissions and restrictions must come through Commission proceedings. In the particular instance of the Midland radios certified under Part 95 it explicitly states narrow emissions only and does not imply modification to wide emissions is allowed within the confines of their certification. As end-users of the product we lack the means and equipment to ensure the radio does not generate spurious emissions exceeding Commission requirements when operating with increased bandwidth. As the final point, our interpretation of a particular rule allows the Commission to either agree or disagree with no middle ground.
  24. As a former Part 90 frequency coordinator I have to state that any change to an emissions designator requires Commission approval. Literally thousands of Part 90 license holders had to apply for, and receive, license modifications to change their emissions designator from 20KF3E to 11K5F3E. Many radios in use had to be replaced as they were not certified for operation at bandwidths less than 20K and modification enabling narrowband operation through any means invalidated their certification. In the case of the Midlands, the manufacturer will have to go back to the Commission showing the change to wideband operation continues to meet the Commissions technical requirements. It is entirely possible the radio exceeds some of the technical requirements when operated as a wideband radio. In response to a petition filed by one Part 90 coordinator the Commission added the reduction of bandwidth with no change of emission type as a change that did not require proof of coordination.
  25. Depends on your definition of attract. By raising the ground potential to a higher point than surrounding possible paths and providing a path with lower resistance a lightening rod provides a more likely path than any other path within the immediate area.
