DX vs. MMDVM

For a while now, its been a little tough to get regular DX the old-fashioned way. Aside from that, FT8 works fairly well on 20m, but that's not for everyone, and it pretty robotic and impersonal. There isn't enough people on HF DV like the FreeDV 1600 and 700D modes, so it's less than a thrill right now.

That being said, there is hope. There has been a tremendous increase of activity on the MMDVM front. With new gadgets hitting the market as fast as baby rabbits, even the Tech hams can now talk around the world, and on an HT to boot! Yeah, it's not like the traditional and personally rewarding "contacts" like we are used to, flexing our RF muscles in cunning and calculated ways, but the end result is the same. Hams talking to hams around the world, and how cool is that!

So my FT-991A isn't used quite as much right now for DX, but the FTM-400XDR and FT-70D are barking up a storm from my ZUMspot and a few connected Yaesu WIRES-X repeaters in the area. My favorites right now are America Link and MNWis. Ride the wave, baby! But if the internet goes down, make sure you are squared away in your own shack. Independence is highly rewarding!

Golf Sportwagen Mobile Setup

Moving my mobile rig into the Volkswagen presents a number of issues. Unlike the Jeep, which had a multitude of places to mount equipment, the Golf Sportwagen makes more efficient use of space for VW gadgets and options. Finding even a little space for the FTM-400 head, without blocking VW gadgets or sitting out of reach up on the hot dash, is quite a task. 

After a few trials, I settled on giving up the use of the storage box in front of the shift console, as I think it's the least intrusive, and safest place. The head is attached with a Ram flexible stem mount, which is attached to a 1/4" thick piece of oak cut to fit in the opening of the compartment I pulled from the dash.

The Sportwagen has a great place to mount up to a few radio bodies. On the driver's side of the rear cargo area, there is a trap door in the sidewall, located behind the rear wheel well. Remove this trap door and you have a solid, removable mounting platform for radio bodies and accessories. It makes for an out of the way mounting location that is easily accessed for servicing the gear in your mobile "utility room". The bodies remain in the climate controlled area of the car, and are hidden when the rolling cargo cover is pulled to the rear.

Power is supplied by a RIGrunner 4005H mounted above the radio body, which is wired directly to the batter with double fuse pairs on each end of the feed line. Power for the FT-991A or any other rig is ready and available for field day. 

The Comet NMO antennas are mounted on two stainless brackets I made and attached to the roof rails. Everything is electrically grounded, so after running the Comet CAA-500 Mark II on the setup, both antennas are about as good as it gets.

ZUMspot Nextion

Ah, the awesome ZUMspot, a digital voice door open to the world! How fantastic it is to talk all around the world with no static and no noise, like everyone is in the same room! Very cool! Between all the modes of digital voice, I have to say my favorite is YSF C4FM for its exceptional voice quality. My second favorite is DMR, but this requires getting used to the frequent "R2D2" picket fence sound.

The thing about the ZUMspot - and many other hotspots - is there is no display. It has the Pi-Star on-board html software, but to see the station information requires using a second device. But since this technology is fairly new, it is evolving very quickly. This is a good thing.

Riding along with this forward momentum, I'm now exploring computer programming for Raspberry Pi, and designing programs for the Nextion display. As it goes, I now have an awesome 3.2 inch Nextion touch display programmed and connected via USB to my ZUMspot. OMGoodness! It is, yes, AWESOME!

Next? Maybe program links to QRZ on the call sign...
