How to hook up a CPU fan in a vehicle for Ham Radio?
I have a Yaesu FT1802m. It has about 2 or so inches on each side for clearance and I need to cool it during long transmissions. Is it possible to hook up a 12v cpu fan to cool it??? If not then what can I do. I drive a single cab manual transmission chevy and don’t have much space to move the radio to another location.
Its the 21st century man….either get A/C or just get a CB.
If you have a 12V fan however, you need a Fused power wire and a ground wire.
Take the Power wire from the battery(make sure it has a fuse), to a toggle switch, from there go to the fans power wire.
As for the ground wire, take and mount the ground wire from any part of the frame(any bolt or screw directly mounted to frame or bare metal will do), to the other prong on the toggle, and from there to the ground wire on the fan.
A few things to remember: make sure the power wire is not run thru the door or any where else that it can pinch
make sure the fuse is disconnected until you are done wiring.
Keep a fire extinguisher handy just in case of fire.

There would be a problem answering this question for you.

This was a very heavy (and expensive) radio and the first part of the film explores the extensive planning and testing by amateur HAM radio operators that it took to introduce the device to the war front.

I have an antenna mounted on a 40 foot lattice type tower. The tower has 3 sides to it, and it doesn’t appear strong enough to handle my weight if I tried to climb it. The power lead for the rotor has disconnected from the motor, so I can’t point the antenna. I don’t have the $250 rental fee for a manlift that will get me up to the antenna, so how do I get up there to fix this?
Thanks for all the suggestions. I convinced my wife that $250 is cheap compared to :
a) a monthly cable bill
b) a hospital bill if I fell
c) the cost to reconnect the power line that comes in to the house near the antenna tower
I rented the manlift from my local rental yard. I explained to the guy that I needed it for a short time, and he gave it to me for less than their minimum daily rate. Thanks again for all the help.
It depends on the tower. If it is a “bolt-together” tower, be extremely careful. You may want to take a wrench along and tighten the bolts as you go up. I had a 100′ tower fold in half because some of the bolts came loose and fell out over the years.
Make sure that the base is secured properly, as well. If an insufficient amount of concrete was used in the base, the tower could “uproot” due to the addition of a couple hundred pounds. If the tower is bolted to stubs coming out of the ground, make sure the bolts are secure, and not ready to shear apart due to rust and corrosion. If you do decide to climb it, wear a climbing harness with a safety strap around the tower as you climb. Secure yourself when you get to the top.
If you are at all dubious of its structural integrity, then don’t climb it. $250 is cheap, compared to a hospital bill.
If you hire someone to do it, make sure they are bonded and insured. You don’t want to have to pay their hospital bill, either.

Simply remove it from the box, charge and insert the batteries, and get ready to take-off. The package is equipped with everything needed to get airborne (except 6AA batteries for the transmitter). Once again, just simply take it out of the box, set the batteries, and you have lift-off anywhere you want! Now everyo…
