Fail!

Last night was a failure for the Tidewater DMR Net. Not that it was our fault … I think I can lay this one right on the doorstep of the network. There were lots of network dropouts, weird noises, and just general failure. I never did get checked in and all of the stations I heard intermittently were having trouble communicating. This brought home … in an obvious way … that in a disaster, like a hurricane and the resulting flooding, those of us dependent on hotspots and the internet for DMR operation would literally be “up the creek without a paddle.” There’s still a real need for that good ol’ RF!

Tidewater 31515 DMR Group

Once again, we met last night for our weekly net. It was a good-sized group, and we had quite a bit of discussion on several topics. We talked about choosing a hotspot frequency … what to avoid, such as national, regional, or local active simplex frequencies, weak signal frequencies, repeater input/output frequencies, satellite uplink/downlink frequencies … and probably some I’ve forgotten. The moral of the story is “don’t use a frequency that somebody else is using.”

We also discussed setting up a groups.io discussion group to keep everybody informed about what’s going on locally. We got a bit of a history lesson on how the 31515 TG came about … who set it up, why it was set up, etc. It was suggested that some of the net members visit local clubs and explain about the weekly nets to increase participation. We already have a few new people checking in most weeks, but the more the merrier!

Finally, we had a check in from Guam! It was an active duty Navy member with ties to this area checking in from KH2-land with his handheld and hotspot. Perfect copy … what a great mode for these propagation doldrums we’re experiencing. He gave us a few details of the recent Typhoon that hit Guam.

We meet Thursday nights at 9 PM Local (Eastern) time on TG 31515. Join us!

Updates

Last night, we had our monthly radio club meeting. We had a good turnout, with some old friends we hadn’t seen for a while, and some new ones. We even picked up a few new members … HOORAY!

Our Treasurer, who has held that position for over fifteen years tendered his resignation as treasurer due to health and family issues, and I was elected to take his place. I’ve really got some big shoes to fill, don’t I?

We had a good meeting, and the presentation was on mobile radio installation. Well done and very interesting. It’s my turn next month, and my tentative subject will be portable operation … Radios in the Wild.

There were ten checkins to the Tidewater 31515 DMR Net this evening. Topics of discussion were the upcoming Virginia Beach Hamfest and IDing on DMR to comply with FCC Regulations … Section 97.119, to be specific. As I’ve said before, it’s more of a casual gathering than a formal net, and it’ll be nice to put some faces to the calls at the hamfest Saturday. I noticed that a couple of new calls showed up as unknown, so I updated the user database in my MD-380. I hadn’t done that for a while.

I also went into my new DStar radio and added some local non-digital simplex channels. The programming in that radio is still a work in progress, but truthfully, with the GPS and built-in repeater database, not much pre-programming is needed for repeater use.

DMR Stuff

I just finished doing radio for the first time this week. Somehow, I just couldn’t get motivated to turn on a radio until our weekly DMR net tonight on TG 31515, Tidewater VA. Each week, we have a few more join us … this week we had thirteen check ins. As the word gets out, people who are interested drift in on Thursday evening at 9 PM.

Most of the discussion tonight was on DMR programming … specifically simplex programming. WZ4K had some pearls of wisdom to impart, and thanks to him for his research and for passing it on. The official DMR simplex frequency for the Virginia Beach Hamfest is 441.000 MHz. I’m really looking forward to the hamfest this year. It’s a chance to put some faces to the net members. WZ4K, Howard, will also be presenting a SKYWARN forum, so that’ll be interesting. I think I mentioned in a previous post that the forums actually interest me more than the sales at the hamfests. There’s also a forum on Mesh Networking that I want to attend.

Lots of Action Yesterday

I was pretty busy yesterday afternoon after work. I downloaded the software for the new FT8CALL and installed it, and then fired it up. It’s a very easy setup, especially if you’re already running FT8 … it’s almost identical. I’ll have to admit, keeping track of all the functions and following the QSOs on the screen can be confusing at first … there’s lots going on. It’s really essential to read the documentation first and then keep it handy to refer to. Will it become a popular mode? I don’t know … it is sort of a ragchew mode, and many don’t seem to be interested in interacting beyond the minimal exchange, but time will see. It does have its place.

Last night, we had our weekly DMR net on TG 31515 (Tidewater, VA), with a good, lively crowd and some interesting discussions. We hesitate to call it a “net” … it’s more of a very loose roundtable. Very casual compared to a formal net. We had eleven area hams check in, which was a record, I believe. We discussed “Static TGs vs Dynamic TGs, a Meet-Up at the Virginia Beach Hamfest on the 6th of September, Talkgroups vs reflectors. I noticed that a couple of the guys were showing up as unidentified on my display, which reminded me that I hadn’t updated the DMR user database in my HT for a while. I did a quick download of the data into my portable and VOILA! … they were no longer unknown!

The DMR 31515 Thursday Night Group keeps growing. If you’re a participant, invite a friend! Everybody is welcome! If you’re not a participant, here’s an open invitation to just ‘holler’ at us when we pause for people checking in.

We also talked about a local DMR simplex frequency and decided that we would adopt 441.0000 (TG99,TS1,CC1) as our common simplex frequency. We’ll try it out and see if we can find each other at the hamfest in a few weeks.
