Hose Line — If your browser fails to produce audio, try another browser. My situation? Chrome fails, but Opera works on Win7 and DuckDuckGo works on Android. It makes no sense.
— If no browser produces audio it is very likely that the Hose Line server software has failed. The only solution? Check back in the days following. I have never seen a webpage announcement one way or the other.
— Some links below to lesser known talkgroups are simply to see if there is activity, and may not remain here. So many unused talkgroups, yet more are added each month. Ridiculous. Sigh…
— An April 2019 post suggests using the URL "hose1.brandmeister.network" as an alternative. Maybe…
Dealers — A selected list of dealers, based upon conversations with persons whose opinions I trust, selling DMR radios. The list is not comprehensive. Links are not endorsements. Buyer beware. Your mileage may vary.
Codeplugs — Codeplugs are enigmas. Whereas it is best to learn to build your own codeplug, looking at samples can help. These repositories may be helpful. Third-party codeplug editors (below) can convert file formats. Ses my notes below.
The MD-UV380 is a mid-2018 dual-band variant of the popular MD-380. Web searches do not yield much information about the radio. In my opinion, the manual could be improved. The folliwing items are notes and observations made since purchasing the radio in July 2018. The CPS software is version 1.03; I haven't perceived a need to upgrade it
Around the end of 2018 TYT seems to have discontinued the MD-UV380. The replacement appears to be the water-resistant MD-390. My readings suggest the internals are the same as the MD-UV380.
The charger is not a rapid-charging unit. It takes 6-8 hours to charge a dead battery. I bought a second battery.
When unboxing your new radio and loading the TYT CPS software, the very first thing to do is READ the radio, and save the initial file elsewhere as a 'do not touch' safety valve backup just in case. I name files in the the format of 'uv380-yyyymmddhhmm.rdt' so I can revert to previous versions.
An MD380 codeplug will not directly load into a MD-UV380. Let's leave it at that. If you seek a MD-UV380 codeplug (as a sample, starter or to study) in lieu of building your own, in my opinion the easiest solution is to use the N0GSG DMR Contact Manager to read in an MD380 codeplug and write it out in the UV380 format. (If you are a new user of the N0GSG software, I strongly recommend first reading the PDF user manual.)
The dual VFOs are not ganged. When one has UHF and VHF repeaters and simplex frequencies in the same zone list, you can listen to traffic on both receivers simultaneously. VFO A audio has priority over VFO B if both receivers are active.
If scanning a zone list with analog FM frequencies and the scan stops, the radio will continue to check for other activity approximately every 3 seconds. A momentary "blip" interrupts the audio.
The MD-UV380 has 3—H, M, L—power levels; page 51 of the manual states only there are only two. I like to have a quick button programmed to change same. To conserve the battery, I program repeaters at M and step to H if needed. Program one of the buttons on the left side of the radio.
If implementing the Pi-Star Remote commands on your radio for use with your hotspot, KE0FHS has a good explanation on how to set up the reboot and other commands. However, for the MD-UV380 and probably other radios, there is one more step to be done. The reboot command fails unless you uncheck the "Private Call Confirmed" checkbox on the codeplug's "reboot" Channel Information sheet. Otherwise, on the hotspot, the DMR logo just shows up on the OLED screen over the rolling MMDVM logo. A ~2 second PTT keypress may be required; the hotspot may not immediately reboot.
A few notes on codeplug manipulation…
There may be a deletion logic error in both the TYT CPS software and the N0GSG DMR Contact Manager. (I would expect the same logic problem occurs in other editors.) Attempts to delete a digital contact and a channel seens to unhook the relation between digital contacts and channels. I have to correct the channel records, adjusting the contact name, to fix the misalignment. In my opinion it is easier to make the corrections with the N0GSG DMR Contact Manager.
Early first impressions is the DMR CPS Programmer by DL5MCC is more difficult to use. There seems to be more dependency on CSV files. The advantage is more or different DMR radios are supported. That said, I haven't yet attempted to delete records using the DL5MCC program while sorting out the TYT software (v1.03).problems. Editcp by WJ2O does not seem to work with the UV380. The first attempt produced a string of frequency 'out of range' errors. After checking the test file with both the TYT and N0GSG software, Editcp won't recognize the 'rdt' file format.
I ran into a problem sharing a codeplug as a Gmail attachment. The recipient of the file reported it was corrupted. The solution was to upload the codeplug file to my Dropbox account and email a link to share it. Other cloud services—Box, OneDrive et al—should work too.
Whither unlinking using TG 4000
The Brandmeister "documentation" on using 4000 to unlink from talkgroups is lacking. We'll have more on the subject in the future.
