As it relates to equipment that is needed to utilize this technology, I’ll try to give you the basics from both Major vendors. \u00a0In either case, make sure you get the right *split*… for the Ham frequencies that you are going to utilize. \u00a0I’m not going to go into the pros and cons of this technology, I’ll leave that to your investigation. \u00a0Suffice it to say at the highest level, it supports both analog and digital on the same hardware, that part is fairly\u00a0seamless. It will only support digital over the Internet connection, there is not way to deal with anything but the digital version when linked via the NDXN linking… Each repeater has a DB25 connector on the back which allows connection of other peripherals. \u00a0In fact all of my repeaters also have AllStar Link connected to them so they can link in either Analog or Digital mode.<\/p>\n
Icom –\u00a0http:\/\/www.icomamerica.com\/idas625\/<\/a> – UC-FR5000 linking board – this is a small\u00a0Linux\u00a0based computer that is mounted inside the top of the repeater or module above. It has an Ethernet connection point and 2 other ports for simple connection to other modules, repeaters, radios, etc. \u00a0(we won’t go into the later as we don’t use those)<\/p>\n – CF-FR5000MC Multi-Site Conventional Linking compact flash card. \u00a0This includes the basic software that is utilized to get the Icom repeaters on the internet and at a basic level of connected to the WW NXDN network.<\/p>\n That’s it for Icom, if you shop hard, you can usually find the above for around $1000-$1100 all in.<\/p>\n Kenwood – http:\/\/nexedge.kenwood.com\/<\/a> – KTI-3 – this is the internet connection module for the Kenwoods, it has Ethernet and what they call N_SYNC ports, the latter being a form of RS-485 and are used for interconnection to other equipment similar to the Icoms.<\/p>\n There is no Compact flash card for the Kenwoods, that is included in the software functionality of the KTI-3.<\/p>\n Both of the above will require the Icom or Kenwood programming software and cable, these are easily found through other Ham groups that may be supporting the technology or through your favorite ham friendly dealer.<\/p>\n Note, all of this equipment is Part 90 certified, and as such, while it supports 25khz spacing and 5khz of deviation today, the Mandate in that space is going to require the vendors to limit it to 12.5khz spacing and 2.5khz deviation on January 1 in the US. \u00a0We don’t know what implications that will have for analog usage going forward, but will keep you posted as we learn that.<\/p>\n","protected":false},"excerpt":{"rendered":" As it relates to equipment that is needed to utilize this technology, I’ll try to give you the basics from both Major vendors. \u00a0In either case, make sure you get the right *split*… for the Ham frequencies that you are … Continue reading
\n– IC-FR5000\/6000 repeater, these come in one of 2 flavors. either the model numbers listed which gets you a full rack size unit with a nice display and buttons and knobs, or the UR-FR5000\/6000. \u00a0The later is the module that is inside the rack case, it doesn’t have the display, buttons or knobs, but it will also save you about $500 over the price of the one with. \u00a0There is no other differences, the same software, programming etc is utilized to make just the module work. \u00a0These are very small, about the size of a hard cover book, but about 4-5″ thick. \u00a0They both are 50W output at 50% duty cycle and 25W at 100%… with other levels of power setting available through programming. \u00a0The 5000 being the VHF version and the 6000 being the UHF version.<\/p>\n
\n– NXR710\/810 – You don’t need the 700 or 800 models, while almost 2X the price, they include no feature that would be appropriate for Amateur Radio. \u00a0There is no module only version of the Kenwood that’s sold specifically that way. \u00a0The 710 is the VHF version the 810 is the UHF version<\/p>\n
