Author Topic: Would you run a Yaesu FT991a in a car?  (Read 466 times)

Posts: 254

« on: August 26, 2019, 10:05:59 AM »

Looking to put an HF / VHF / UHF radio into my car.  I used to run an Icom 706 MKIIG, but want to put something new in the new F150. 

I know I could put an Icom 7100, but for close to the same money, I could buy a Yaesu FT991a.

Was wondering if anyone say any reasons not to do this?  I know it's a bit large, but no larger than the old Icom 730 / Kenwood TS130 radios that I used to run mobile.

Would the radio not be happy with the frigid temps here in Mass? 

Thanks for the input.

Rather "busy" menu system on the yaesu.  The 7100 is easier to operate.  The 991 menu system don't matter in the shack, but in a mobile.. Maybe not as good?

Quick answer = NO. The 991 does not have a remote/removable control head like the 706/7000. The 991 is half again as big as the 706 more on the near the size of a Kenwood 430. Do you have room for this big radio or consume your passenger seat/legs?

I recommend you find the best mobile HF/VHF/UHF w/digi-DSP radio made the IC-7000. The tilt/angled display of the 7100 sucks and your sweaty finger prints on the touch-screen will leave you very frustrated (the FT991 is touch screen too).

Conduct you own test in bright sunlight wearing polarized sunglasses - what display can you see (especially of your display is on top the dash adjacent to your windshield under your center mirror)?  Cool

I'm seeking a method to mount my FTM-400 & IC-7000 control heads on one mount, on my windshield dash under my mirror since my Tacoma has no other place to put the control heads and allow me to keep one eye on the road. Angry

I like touch screens, and once in a great while when the sweaty grime gets too bad you can wipe them clean with a soft cloth in seconds. Auto manufactures like touch screens too, because they put them in EVERY modern car.  Even my minivan has one. Looks great, works great and lasts a long time.  Smiley  I like modern stuff.

Did you look through the Yaesu FT991 docs to find the specified operating temperature range? The LCD displays in desktop ham rigs are designed to be viewed at room temperatures that are comfortable for humans. I know that my own IC706Mk2G display had serious viewing problems when it was below freezing.

Others have already suggested how to test the display viewability which is essential for mobile operation of your ham rig. I'll add that mounting ANY control head below the rear view mirror is asking for legal trouble. First, that location obstructs your view of the right side of the roadway, which is a safety violation in all 50 states. That's independent of any possible amateur radio exemptions to distracted driving laws which do vary by state and locality. Second, in the event of an accident the radio head can become a deadly flying projectile, whether the crash was caused by others or yourself.
Vehicular radio equipment should never be surface-mounted on or above the dashboard and should always be clear of any airbag or crumple zones in the passenger cabin. Check with your local PD or DMV inspectors about the view through your windshield, and verify with your auto insurance carrier the details of what they do and don't cover in the event of a crash.

I remember back when the old Kenwood TS130S came out. I had one hanging under dashboard of my old Dodge. I worked a lot of DX back then with that little radio.

To answer your question: YES ! If I had room for it in my car, I would. I do have a 1989 Dodge Van, garage kept, and I would use my FT991A in it if needed. It all comes down to, "does it fit in your can and are you going to kind of set it and forget it?"

If you want to go through all of the features this radio offers, the menus will drive you nuts and you'll be taking your eyes off of the road way too much. If you set it and forget it......pick a band and stay there, I see no reason for NOT using it mobile.

Once you set it up, it really is a great little radio with great powerful audio. Like CW? Great for that as well.

Bottom line: I would use mine mobile and work CW as well as SSB mobile.

I only use my van for hamfests and home improvements. If I was to go on a long trip and take the van.....I have a TS480SAT and the FT991A. My choice would be the FT991A, Hand Down !

For space issues, there are better choices.
