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...

Yaesu FT-991A with GPS

I'm not sure why, but the Yaesu FT-991A does not come with a built-in GPS unit. So if you want that data included in digital QSO's, you will need to connect your own external GPS antenna. Now comes the Garmin GPS18x PC, a fully compatible NMEA GPS, WAAS enabled antenna that connects to the FT-991A's GPS/CAT DB9 serial port. Power is supplied by a 12 volt plug into my Yaesu FP-1030A power supply.

Setup is pretty simple with radio menu 028 set to GPS1, which is the the default setting. Plug it in, and turn it on. Wait, slow down. Did you get that?

Now when you key up on a C4FM repeater - as well as with a few other functions - your location/distance is also transmitted/received for the other stations. And if it makes your day, you get the cool little green GPS satellite icon showing up on the FT-991A touchscreen. Nice!

Update: Oct 2020 

With a Powerwerx PowerPole-to-cigar lighter adapter, I plugged this into my RIGrunner 4007U because I kept hitting the plug sticking out the front of the power supply. This GPS is working great!
