Re: Anybody have experience installing in a Prius ?
Mike
Thanks for the response, I've never had to ferrite a radio before, but since I was smart enough to ask before doing the install, can you make suggestions for the ferrites, depending upon the size I would plan to place the on the power leads when I take apart the existing Molex plug and replace with power poles, so they would be permanently?installed then.?
I was planning a APO unit, and a 2nd isolation unit, for a 2nd battery, I need to dig out my notes, 2 batteries in parallel, 2nd larger battery can be charged by car but radio cannot draw from the car's primary battery. I've lived the fun of a dead 12 volt battery in the prius before, I can proudly say not from any of my own foolishness though :-)
I'm leaving options open for the antenna side, I have some NMO mounts laying around, think in the long run it will probably be 2 antennas a U/V and the ATAS

Here is where you might run into some limits.
Don't be shy about RFI resistance in the vehicle.
Put ferrites on the output of the radio as close as possible, most people don't know how much stray rf comes off the power cables.
Since the 12 battery is dinky I strongly urge you to use an APO 3.
This is a voltage sensitive relay. So when the car is on it will turn on a down stream load.?
When the car is shut off, it will wait some programmed time then shut off the down stream load.
This will keep you from learning how un fun it is when the 12v battery in a Prius goes flat.
In my wife's car I have two radios. An old Midland LMR 40w two meter set (converted to ham service) and a custom APRS radio.
They work fine.
With the car turned off, don't expect to transmit on just that dinky group 51 like battery alone, it is short on amps.
The car must be on and let all the DC to DC converters do their magic.
As for antennas I like Larson NMO's and you can buy little right angle brackets that fit into the drip channels inside the hatch area.
Hope this helps.

Re: Anybody have experience installing in a Prius ?
Interesting concept, never though of doing that. How do you attach the wires to the magnets?

Anybody have experience installing in a Prius ?
Finally getting around to doing an install in my 2010 Prius, I know discontinued radio for a 10 year old car.?
I have the separation kit, and an ATAS-120, and a Comet mount, debating between the Comet bolt on and fabbing my own for the antenna.
Think I'm going to cut off the factory molex power connector and re-terminate with power poles, thinking of doing all 3 wires, and building a short adapter that grounds the brown wire, I can always then pull that short adapter out if I want in the future.?
Any hints from others with experience in a Prius would be appreciated.

Re: Need help - fuses / power issue
I had to advise an electrician that the reason the accelerator or gas pedal cable and the choke cable caught fire was;
The engine is mounted in the engine bay on rubber vibration mounts to acoustically keep the noise in the vehicle down.
These mountings being rubber insulated the engine body from the vehicle body.
The negative of the battery was grounded to the vehicle chassis.
The engine has a grounding strap to the chassis, but it is loose so the power to the ground is going through the carburettor. FIRE RISK!
He replaced the grounding strap, end of the problem.
So have a negative fuse as burned-out wiring will put your wife/partner and children at risk of being burned.
Why did he have a loose ground wire? He put a tank battery in the vehicle. Why I do not know and he was an electrician on vehicles! Yes, tanks.

This is the issue. The fuse on the negative is to protect the radio from a
failure of another device in the car. Its not unusual for many to not
understand this and why.
That only applies if you are ging to somehow try and bridge engine block and chassis using your radio Negative fuse is pointless Pete

Tuner is off but I found the problem. ?Somehow I had gotten into the multifunction MFq and key C turns on/off a 2 sec tone of 1750 for ATC. Don¡¯t understand all this yet but tone is gone.

Loosely quoted from manual " a carrier signal will be send to setup autotuner....".
Did not find an actual frequency of the tuning signal, but sure sounds like you have autotuner activated.
I believe there should be a display on LCD to say "TUNER" or something similar if that is the case.
Also verify - the tuner (FC30) is not designed work an some bands .
But if is not programmed it should not matter.

It almost sounds like wires-x is enabled, like on the FT-8800. But as far as I know, the 857 doesn't have wires-x functionality.

Re: Another look at the Yaesu FT 857D
Respectfully disagree - even dubious values discussions are better then just say "o well ... put it in bed ".
Some replies are rather typical - difference of opinions and expressions? are emphasized, instead of technical contributions of the posts.
In MY case the reply was in line with George Carlin " shell shock" monologue.
The article is IN MY opinion misrepresentation of FT857 and amateur radio hobby.
So I called it garbage.
IN MY opinion, if we do not call spade a spade , as in this case , "we have met the enemy and it is us" .
Anybody can express their opinions about FT857 , even about articles about FT 857, however when my rating of the article became MAIN subject of a reply I cannot help but ask
How did criticism of my opinion , which is none of anybody business, contributed to the "another look at FT857"?
|
Re: Need help - fuses / power issue
It would be nice to continue TECHNICAL discussion without commentaries such as this "Its not unusual for many to not understand this and why."
In the spirit of learning and not preaching , if I may continue here.
1. Give an example how this can occur , given we are still talking about single amateur radio installed in a vehicle.?
"another high current circuit opens for some reason and finds its way back to the battery through the radio and wiring."
2. Assuming that the rig in NOT isolated? from the vehicle (ground)? - fusing negative lead is relatively superfluous - it is? better and (another) KNOWN and main? path to the battery negative terminal. And if such? negative fuse blows - where woudl be the path to the negative battery terminal then ??
3. Connecting the positive lead as close as to the positive battery terminal (UK rule) AND fusing it with BETTER? fuse holder is the solution here.
