H3 CE Now Has Comms

I am finally getting around to documenting my install of the communications gear in my '09 H3 CE.
I got my Technician ticket in June of this year, and upgraded to General in July.
The radio that I selected as my first, is the Yaesu FT-857D, which is an all-mode tranceiver that operates on HF, 6m, 2m, & 70cm. I chose to mount it utilizing the included remote mount kit, and the MH-59A8J remote microphone. The antennas that I chose were the Little Tarheel II HF Screwdriver which, with the included 32" whip, will tune from 3.5 MHz to 54 MHz. I also bought the 56" whip, which gives better HF performance at the cost of losing 6m. The LT II will not tune to 160m with either of the whips. I also chose the Turbo Tuner to automatically tune the LT II to resonance on any frequency within the antenna's range. The 2m / 70cm antenna that I chose was the Comet SBB7NMO.


The FT-857D base unit and the Turbo Tuner is mounted inside the storage compartment in the rear cargo area. The power & ground wires for the tranceiver are #12 stranded that are run through a hole in the compartment's back wall, behind the rear right trim panel, under the rear cargo door sill. Then they go behind the left rear trim panel, under the left rear & front door sills, behind the driver's side kick panel, and through the firewall grommet to the battery. There are 25A fuses on both the positive and negative leads at a point before they hook to the battery.

The removable door for the compartment has been ventilated to allow heat from the tranceiver to escape.

I wanted to mount both antennas mounted high on each of the truck's rear corners, just above the taillights. With the help of a friend, who has crazy fabrication skills, we fabricated mounts for both antennas out of 3/16" flat steel that bolt to the upper body behind the rear corner plastic trim pieces.

Both antennas are QD so that they can be removed, or replaced with shorter versions for wheeling, if necessary. The coax used for both antennas is RG-8X, and enters above each taillight, then goes through the taillight wiring grommet on their respective sides, and into the inside of the truck.

The 2m / 70cm antenna is on the left rear corner, and its coax, after passing into the truck, travels underneath the rear cargo door sill, then behind the right interior rear side trim panel. The HF antenna is mounted on the truck's right rear corner. The coax, along with the screwdriver's control cable, then passes through a small hole that was drilled into the rear wall of the storage compartment. The radio's remote head cable, the remote mic cable, and the remote speaker cable pass through a small hole that was drilled into the compartment's front wall. They travel behind the right rear side trim panel, under the right rear passenger door sill, under the right front side trim panel, to a point even with the front passenger seat. There they travel under the front passenger seat carpet, through the seat wiring harness hole in the carpet, then under the center console. The control head cable travels under the right side of the console to a point near the console's front cup holder. The control head is mounted on a shortened Lido cup holder mount.

The remote mic cable travels under the left side of the console, to a point near the front edge of the seat, where it is fastened to the side of the console. The mic is hung on the center stack, to the left of the Am/FM/XM radio.

Note that I have a Cobra 75 WXT CB mounted to the side of the console, at the driver's knee.
The junction box for this unit is under the driver's seat.

The remote speaker cable travels to the rear of the center console, where the speaker is mounted.

The FT-857D with these antennas is doing a great job. On 2m/70cm, I have been able to hit all the local repeaters as far as 40 mile away. On HF, I have made contacts that I would have never dreamed possible from a mobile unit. These contacts include stations in Texas, Arizona, N. Dakota, Louisiana, Missouri, Kansas, Germany, and Croatia, all on 20m, and a contact in Spain on 17m. I'm still a newb at all this, but from what the local hams are telling me, this is pretty good performance.

There is a RocDoc CB antenna mount on the spare tire mount bolt, with a QD antenna connector.
I use a Wilson Flex 5, with the coax and ground installed per F5's instructions.

Neal,

THAT IS FANTASTIC!!!! The FT-857D is the exact radio I want for my H3.

Currently I have a VX-8 and a Diamond SG7500; works well however I could use more power than 5w. In the mountains the 5w is kind of limited. I found out helping on a burro race that I was not reaching the net control down the pass.

Nice stuff! Heck, I was impressed at how nicely you drilled those holes in the cargo area cover. I would NOT have the patience for that.

Nice installation and great write up. I suspect that you and Mikkel will have a lot to talk about. ( LagunaH1 )

Really, really, nicely done! The way you mount the Tarheel probably gives you really good ground as well (something I'm struggling with on the H1) Reaching Germany and Croatia on 20 meters is *great*, although you are "cheating" by being on the east coast :p

We should try and work each other some time when 20 is in good shape.

My setup works best on 20 and 15 meters, so maybe Sunday afternoon? somewhere around 14.300?

Very cool! Please post here when you get that done, would love to learn about how you get things installed and how well it works.

Neal and I DID manage to talk to each other from coast to coast via HAM radio today. I was parked on my favorite hilltop overlooking Laguna Beach so I had some decent altitude. At first, it was tough to copy but it got a little bit better after the first couple of tries. We had found a clear frequency on 14.303 Mhz.

This was fun!!! I'd definitely be up for trying again some time, maybe we can persuade other fellow Hummer / HAM / HF folks to join us some time.

Edit: I should add that about half an hour earlier I had spoken with ZL2CS on 10 meters. ZL2CS is located in New Zealand!

Yeah, It was pretty cool!
:thumbs:I had just got home from a 9/11 memorial service, so didn't have time to go to high ground. the closest "high ground" around here is 30 minutes away, and the "window" that Mikkel and I had set was closing, sooo, I just pointed my truck west, and tried from right there in the driveway. On my end the QSO was just above the noise level, but entirely readable. You have to remember that this was mobile to mobile, barefoot, and no beams! I was extremely pleased.
I'd be up to trying it again, and maybe this time I can find some altitude to transmit from. Altitude is your friend in this case! :wink:
Thanks, Mikkel!

On 09/11, at 23:06 EDT, I had a QSO with ZL1BD in New Zealand on 14.255.56.
According to QRZed, that's 8364 miles. My longest distance contact so far.

Yet I barely have a signal to/from dispatch at a low point a mere 6 miles from the station... argh. Pretty cool you got across an ocean.

Sweet!!! How cool is that!

To me, this is the essence of why HAM radio is cool: You call a station far, far away and when things go right, the other station ANSWERS, even if they are in New Zealand or some other far away place.

I'd love to coordinate a monthly HF net for all of us who are into HF. We I'm sure we can find tons of things to talk about between our Hummer and HAM radio hobbies. MaxPF, you totally need to get yourself an HF rig! Anyone else out there who'd be interested?

Know exactly what you're talkin' about. With our 800 MHz work radios, we have parts of the county that are very hard to talk into, or out of. Very frustrating, and a huge officer safety issue.

Sorry to hear about the lack of coverage on your work 800 Mhz systems. I know there is a TON I don't know about radio and propagation but I do know that the higher frequency, the more "line of sight" it becomes. I'm thinking that that's probably a big part of why the California Highway Patrol uses a 6 meter FM system for a lot of their dispatch work.

Is your friend able to make more of these mounts? I could really use the one for the Tarheel.

Your work looks impeccable.
