Desert Experience

Desert Trails RV Park site 15, Tuscon Estates, Arizona

I haven't been able to do anything with ham radio since Nancy's illness. It's been about nine months since she passed away, so I am slowly moving forward with my life without her. I took off from the Wisconsin winter snow shoveling by staying at an RV park in the Tucson area for two months. I have a few more days here before I start heading home.

Before I left home, I thought I would bring the FT-991A and accessories along, and I'm sure glad I did. I mounted the radio by it's mobile mounting bracket to the cabinet shelf I made. I placed a fused line directly from the battery to the RigRunner so I can have extra connections for the Garmin GPS and a few other things, and my Heil mic is on a short boom. So far it has worked out great! An upcoming test will be when I get back on the road with the trailer. I'm planning on leaving everything in place except for the antennas.

The Yaesu FT-991A and FT3D in the camper

For ease of operating, I purchased a Yaesu ATAS-120A screwdriver antenna for HF, and a separate 2m/440 antenna, both mounted to the rails on top of the all aluminum camper. I made some heavy braided ground bonds from the mounts to the aluminum skin roof. So far, so good, but I will likely make two custom mounts from aluminum and bolt them directly to the roof. The SWR suffers a little with the current setup, so I believe a closer bond to the counterpoise will likely fix that.

With this setup I quickly made eight contacts, four of which are trans-equatorial on 10 meters. Pretty fun thing to do sitting in a tiny camper! I can hardly wait to do this in the middle of, well, anywhere!

Next on the list is getting my Raspberry Pi computer in the camper so I can use my logbook and other ham software while away from home.

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!
