I have 50 years’ experience in electrical and electronics repair I earned a First Class Radiotelephone license when I was 17y/o. The FCC has since changed it to a Commercial Radiotelephone license and dropped the renewal fee. I have an Amateur Radio General Class License (KC9QAB). I retired in 2008 after my company moved south. After retirement I went to college and took courses in Design Technology, I am three courses short of a degree.
Resposta para "Will a wet iPod ever work again?"The rule of thumb for any electronic device is to remove the power as soon as possible. The water does not damage the electronics; it is the current passing through the water that causes the damage. When the current passes through the water it sets up electrolysis which is the current in the water eating away at the copper traces on the circuit board which is evidenced by a green slim on the circuit board. I dropped my phone in the toilet and immediately removed the battery. I then took the phone completely apart and rinsed all the parts under fresh water and used a hair dryer at a distance of about 12 inches so not to melt any plastic and dried each component, pc boards, membrane keypad, and the display board. The display board was the most challenging because water got between the layers. When everything was dry I assembled all the components and powered the phone on and it was like new. Pete KC9QAB
Resposta para "How do I install it?"A mobile 2-way radio will work best if it is mounted to the metal chassis of the vehicle. The antenna is the most important part of the system. It should be mounted again to the metal surface of the vehicle for the best ground plane. The ideal location would be the center of the vehicle so the radiation pattern is omni directional, meaning it radiates equally in 360 degrees. The best place to get power from is the battery terminals. If you get alternator whine you should purchase a noise suppression kit. Grounding is critical for proper noise suppression at the lower frequencies such as the 27 Mhz range. good luck, hope this was helpful. Pete KC9QAB
