After 6 months of sitting on the shelf, @KC4HAD convinced me to sit down and make this thing work.

openSPOT is a standalone digital radio IP gateway / hotspot

Key features:

  • Supports DMR (Brandmeister, DMRplus), D-Star (DCS, REF/DPlus, XRF/DExtra, XLX), System Fusion (FCS, YSFReflector) networks. More supported networks and features will be available with new firmware releases.
  • Supports cross modem modes. Talk with your C4FM radio on DMR, and with your DMR radio on System Fusion networks!
  • Very easy to use, works without a computer. No additional hardware required, works out of the box. All accessories included.
  • Web interface for configuration and monitoring.
  • HTTP, UDP/TCP API support.
  • Custom 2FSK/4FSK RF protocol support with TDMA.
  • USB powered, low energy consumption, 20mW RF output.
  • Create your own private radio network using our open source server application.
  • Runs fully embedded software written in pure C, running on an embedded real time operating system. No Linux, bulky Windows software or failing SD cards

 

One of the most interesting parts of this (for me) is getting a current status log, with user info, etc.  Kinda fun..

Was having quite an issue finding the correct software for my Hytera PD362.

 

Finally!  http://gigaparts.net/downloads/    gigaparts seems to be the local dealer for the ham line of radios, and offers this stuff for download

CPS 205.03.002 NA2  is what worked for me, After a quick run in with a “fake” prolific chips programming cable, I can at least read the radio!

Since I joined the P25 crowd, I’ve kept a VHF radio in the truck almost all the time.  This has been great fun, with the exception of dealing with the antenna each day.  My parking garage at work is very low, and I was getting out of the truck twice a day to move it.

Yesterday I purcased a Diamond K9000 motorized antenna mount.  From the comfort of the truck I can UP to use, or DOWN the antenna to safety.

During install, I noted a few things.  First, the documentation for mount type is vague at best, and thus I ended up with the wrong one, though I made it work.  Second, the “control” box is lame and goofy looking.  Luckily it just sends 12v one way to raise and reversed to lower, so I can easily make something more desirable.   The unit has limit switches, one fixed, one adjustable.  This lets you set the amount of “down” and you pre-load the “up” at install time. You must hold the button on the control box down till it reaches the position you want, as there is no way to tell where it is in its travel.

Last issue I will have.  I installed an NMO mount in the K9000, The K9000LRM accepts ground-independent antennas, which I do not yet have.  I’m not sure how this will impact the SWR, but I’m not expecting great things.  More on that later.

Here’s all the programming info for the Icom U-16. (The H-16, V-100 and U-400 are programmed in the same way. There are some slight differences between the H-16/U-16 keypad and the EX-494 programming keyboard used with the V-100 and U-400.)

The H-16 can also be used to clone an H-16, V-100 or V-200; the U-6 will clone a U-16 U-400 or U-200. Appropriate clonig cables are required.

If the U16 has been made programmable by moving a jumper:
Hold FUNCTION KEY down and enter 159357 It’s now in programming mode.  Exit with FUNCT-CLR.
If the jumper has been removed a colon will now show up between the Ch and channel number. You have only 30 seconds time between entries or the radio will time out and return to operation mode.
