I had a CB for years before I upgraded to the 2 meter. In my area of the mountains, the CB did not seem very effective. Every I have turned on the 2 meter I always managed to pick-up a strong transmission, but have only twice made the effort (
awkward) to transmit and talk with someone. For some reason I seem resistant to spend the time to master my technology. With all my gadgets generally I only get a little beyond turning them on and off.
Here is a cooking thermometer that monitors a location on the lower backside of the cylinder. I drilled a hole in the vertical supports between the cylinder fins. The thermo probe inserts the full length and rests against the cylinder. I then packed that section of cooling fin with some nice
insulating material. I as well insulated the backside of the gauge to minimize the effect of the hot exhaust. As this is just to provide a 'bench mark' I generally see the needle at 300 degrees. The hottest it has been is 350. Gerry
