Modest "Digital" Mobile Setup

Years ago I had my old mini-van loaded with piles of Motowiz gear and Yeasu HF gear. I also had enough holes in the roof to ruin any resale value! Well times have changed. I still have all the great commercial gear, but I just wanted to hear my great digital scanner and play a little digital amateur radio in my new van. Most of the old gear was not digital, so new gear was in order along with a modest setup that did not take up too much space....and NO HOLES this time. The antennas I use now work just fine. More on that later.

I have installed my GRE PRO-197 for monitoring just about anything AM/FM/N-FM/P25 above 25 MHz, and my new Icom IC-91AD D-STAR amateur radio (VHF/UHF), which can come out quick for portable operation. The install is almost complete. Two items will be added to complete this setup, although I can run low power now as I am using a hadset mic. I am looking for a Mirage BD-38G (or non-"G" model?) dual band amp (not produced anymore) to take the heat off of the HT and give me up to 80/60 V/U watts. I am also awaiting an HM-75A speaker/microphone I just ordered which has some function controls that will be helpful in the mobile environment. Only the mic part (not the speaker) will be used. For a speaker I am using an old Motorola metal style amplified motorcycle speaker that sounds super loud and has great sound quality (don't make those anymore either!). The scanner is using a newer style motorola speaker. Both are on the floor. If you look close you can see my FM Broadcast filter for the GRE scanner on the right. ;)

The antennas are NMO mag mounts that I can change antenna types on the fly if I need to. Both shown here have the old Antenna Specialists low profile NMO mounts (no coils inside) with the old chrome springs. I love those! I use the 54" whip on the scanner. This works great even on 800! No cell site overload and great range, fantastic low band reception, and resonant 3/4 wave on VHF HI. Even UHF works well enough. The 19" whip on the back is just fine on VHF and UHF for the Icom. The whip is a bit thick, so bandwidth is very good. UHF is also tuned well as a 3/4 wave. Works great on both bands!

The IC-91AD is not just resting there. I have a loop fastened to the ashtray cover that the belt clip slips into. Everything is secure enough to even press the keypad buttons without a problem. It is easy to reach and see. The wires are out of the way, and that coax with the right angle SMA is good stuff (low loss). DC power comes from a 12 battery power pack under the center tray (also has an AC inverter for 110 VAC needs) that is charged when the key is in the ignition. The pack filters the DC and allows 5W TX on the Icom anytime. The battery on the Icom can be removed or can be charged during operation. One last detail you may not notice is the mic extension cable I made to allow me to plug in an external mic. It is on the left side of the scanner bracket. My headset is plugged in now until I get the HM-75A.

Overall this is a very functional little setup. I can hear alot with these two radios...even shortwave stations on the Icom. I can hear D-STAR (and talk on it), and the scanner hears much...and hears it well. HF would be nice, but then I have to mount that big honkin HF antenna you see on my old van. I do have a tow hitch and a tow hitch mount that HF antenna that goes in it, so I could, but where do I mount the FT-100? Food for thought! :D

Hello there! I was beginning to think no one liked my "modest" setup. :(

Thank you. It is a big step down from all of the commercial gear I used to run, but this time I went for the most bang and flex for the buck (with full digital capability) in a small simple package. What I did not include in my setup photos was my laptop. It sits right in the middle on the center tray and blocks the view of the radio equipment. Of course you can close the computer top if you need to see, but the computer can also interface with both radios and display on the 16:9 "wide screen" if you want. My computer has very low EMI/RFI noise output, so there is no degrading the reception by running it (very important)...plus I use multiple ferrite chokes on all leads to reduce any possible stray RF.

The computer runs Street Atlas USA for navigation with a super small GPS receiver/antenna that is installed on the dash all the way up front by the windshield. No wires are visible. The computer also has an AVer NanoExpress DTV (express card slot tuner device with no obtrusive bulk sticking out of the computer) HDTV card that can display full 16:9 1080i HD and even record or play back full resolution HD programs. That's right...OTA digital HD TV DVR in the car! I have a 15" whip antenna (1/4 wave VHF and 3/4 wave UHF) on another mag mount that I can put up if I want to watch live TV. I tried it on my trip to DE and it worked great. Almost went off the road watching the hot babes on a playback of "So You Think You Can Dance" while driving around DC. :lol: I have to be careful about that! Of course you can't watch OTA live TV while moving due to the lack of error correction in the protocol, but as soon as you stop the car you can. I am awaiting the new "mobile DTV" equipment to be sold. I might upgrade at that time.

Overall this is very a functional mobile setup. Now if only I could find a place to mount my FT100. Then I would be able to do HF and 6m using my HS screwdriver antenna mounted in the tow hitch. Hummmmm...there is that space below the AM/FM/CD where I could remote mount the control head...hummmm? :D

Phil :cool:

EDIT: OMG! I just placed the Yaesu FT-100 control head under the car radio...PERFECT FIT! :eek: I guess I know what I have to do now. Back to work! :D

Phil, looks great! I love how some vans just have PERFECT mounting spots!

Can't wait to see the FT-100 in there now!

Thanks! I have a little work ahead of me.

My old Caravan did not have the center tray between the front seats. I had tons of room for my radio console. This van is different. But somehow it all fits with the HT and scanner. The FT-100 will fit perfect too! But now I need to locate a separation cable to do it. Shouldn't be too hard. I'm on the hunt.

Do you have a van installation?

No van installation now, but I did have a van while the Yukon was in the shop. I was able to temporarily put my Spectra, BCT8 and 396 in there. Worked perfectly. Spectra head under the front dash, BCT8 in front of the cup holders and then the 396 beside the OEM radio with adhesive.

There you go, colby. Sounds like you were loaded. I just love my mobile radios. So much to hear as you visit different areas. I feel like doing another road trip! But I have to save my money to build out the rest of my mobile installation. It will be worth the wait.

Peace!

Nice and tidy, I like it.

Do you have trouble getting the SMA screwed down tight enough? I have a somewhat similar - yet not so elegant - setup in my Accord, with a Yaesu VX-7R and a GRE PSR-500. When attaching the Yaesu, I found myself having trouble getting the SMA connector tight enough with my fingers. My solution was a rubber grommet, large enough to just barely slip it over the outside of the SMA connector. It gives me a larger area for my fingers to hold on to and the rubber helps me to grip it as I tighten down on it - yet is flexible enough to prevent me from overtightening it.

Yes, maybe too tight! :eek:

The trick is to hand tighten it just before the cable hits the knob, then use the right angle part of the SMA to "wrench" it tight. It works well. In German we call it :gud en tight". :lol:

That Motorola amplified speaker sounds so good too. It can get very loud if you need the boost in a high noise situation. It even shuts down when no audio is fed to it, so it is silant on standby. Now all I need is the RF amp to help my range. I will put it in-line under the drivers seat. I'm looking for a Mirage BD-38-G. It should drive well at 1/2 of a watt to give me a boost and help keep the IC-91AD cool. At 5 watts drive I should be able to get 80 watts VHF and 60 watts UHF. It is the perfect amp. Too bad they do not make them anymore. :( I'm on the hunt though.
