Hi Laryn, Another war story also told over here some time back. One UHF box we have in service went numb after about 3 months. Checked everything out to spec... even the feedline looked good on fwd and reflected power.
After a lot of head scratching... We replaced the 4 month old LMR-400 with Surplus 1/2 inch Andrews hardline and the receiver started working again. 30 mile distant portables could again reach the box where before the fix even 30 watt mobiles had a hard time getting in. Yeah it happens... skipp > re: LMR-400 > And I wonder how many of these <no movement> scenarios actually suffer > from slowly decreasing sensitivity in their receivers, caused by the > thousands of diodes in these cables producing a slow increase in white > noise as the cables degrade. > > Laryn K8TVZ >
