Taxi Driver Online

hi guys just wondering...

1) this is one of the best radios to get through to your base on i hear is this correct?

2) if buying one on ebay for eg. and they give me the serial how do i check what freq it takes ie i need vhf

3) looking around for this radio i notice a lot of places state
"Programmable Power 5-25 W, set per channel from 2 programmable levels"
how would i bump the power up to the max to get bext push-through to the base?

thank you

oh ps i notice this gm350 can run upto 25watts, but have found the key km150 can push at 50watts, but is almost impossible to get the eeprom programmed with the required base frequencies...

so 4th question is, is there another vhf taxi radio that can be programmed by my local radio shop that can pump out at 50watts or overcall other drivers?

You would have it confiscated by the DTI if you did that.

Think you must be confusing taxi equipment with the old CBs. Pretty well all mobiles are set to run at 25watts and it doesn’t make a jot of difference whether your using a Motorola GM350 or any other make. If it's working correctly and the antennas ok you should be on an equal footing as everyone else.

The best bet is to buy from someone who can put in onto your frequency that way the person doing the job will make sure it's working before selling it to you.

thats what i thought, but i can be sat outside my base and be over called by some one who is in town (8miles away) ive just come to a point where im sick of it. the antenna is brand spanking new just been installed in a brand new passat tdi by professionals at midland radio links and have always had this problem so dont think there is any antenna crimping issues.

what do you suggest is my next course of action to boost up my radios output then. someone advised me to use better wire ie gold plated high power amplifier power cables (they think it allows more power to run from the battery source to the maxon unit - dont see how this would make a diff)

thanks for your time to reply guys, you can imagin the hell im going through when i get walked over from someone 8 miles away !!!

cheers

i know the dti would not like this, but lets say this is for 'educational purposes' is it poss then?

Sounds to me that you do have a problem if that sort of thing's hapening.
Forget about gold plated leads, that's not going to do anything to solve anything.

If as you say your antennas new, then either, your radio is just not working properly, which can only be sorted by getting a competent radio company to carry out a full check on it, or you have a poor power connection. This latter point is so easy to miss. It only takes one loose or corroded connection and that's it so make sure your set is wired directly to the battery via good quality thick cable and propper fuses. Thin wires, fag lighter adaptors, corroded fuses and loose connections might make the radio light up right but be useless when it comes to pulling any current through them.

The transmitted output power must be checked against the car manufacturer's specifications, which a lot of the time is stated as a maximum of 10watts. Running 25 watts therefore could invalidate any manufacturer's warranty and indeed insurance on the vehicle as it is not within guidelines...

It could be a duff mike try someone else's in your radio

duff mic? i can here the base and they can here me clear as day. would this make a big effect on the power i come through at?

It also could be the aerial, I had mine fitted, but the earth wire was touching the center one and I could not get through to my base a mile away get the PL connection re checked

already checked thepower leads a week after having this problem they said its fine after taking a look. =( wish that was the answer.

i had the gm350 before and found it ace at getting through.

would a long whip and a short arial have much effect on getting through by being out side... i know they make a difference on how far away i can receive the base and viser versa but not sure about power

Your aerial should be the same length as the rest of the cabs, or it wont work, If you have a full length one and the rest are short cut it down to the correct size measure it against one of the others,
As I said above get your aerial connections checked by someone with the correct meter, all it takes is one strand of earth wire to touch the center one and it wont transmit properly

i see what your saying, ill have the arial checked again as i need to pop down on monday anyway. but we all have different arials some have short stiff ones about a foot long and some have long bendy ones about a meter long.

our freqs are
base trans 167.625
driv trans 172.425

I dont know how the hell the drivers frqs are diferent they should be the same as the base, for eg when the cb's where in use you had to be on the same channel to speak even though sometimes you could hear maybe 3 channels down
I would get that checked as well
