Tip & How-To about Radio Communications
Radios especially AM bands are simple to work with. Its mostly about antenna adjustments, microphones,Swr, grounding. Check SWR on radio to say 1.5 ratio, which is good. Ground the heck out of it. Drive 8 foot copper stakes into earth,also to water pipes,metal filing cabinets,chain link fences...Connect all these to your radio metal, or black ground. The better the ground stronger the signal. Make sure Antenna is off the ground 15 to 35 feet. I use Tv pole on mine.Use big supergrade coax low-loss 50 ohm. All Am radio is 50 ohm loaded. Internal adjustments to radio is not needed.. But, if you do, make sure you chart what you did and mark your IF canisters with nail polish(setting factory). Clip diodes for Modulation or turn up a VR4 or VR1 or so. Each model has different setting Variable Resistors(VRx). Make sure you read all about it on DEFCOM RADIO MODS or SNAKE DOCTORS RADIO MODS--Before attempting internal adjustments..Use micro screwdrivers only. Remember the best antenna for CB frequencies is "102 inches" 8.5 feet. Build your own and have fun.
