i have a generic walmart 32gb Micro SD Card in there now.. and it's still the same as before.. im still having to use the trunking discovery favorites list with all the systems in there just "for backup"
More than likely it popped a RX amp by the overload from Radiation or Magnetism less than $100 and shipping.
There are several users here that would buy that for $100 in the Classifieds send it off to be repaired for $100 sell it for $350 to $400 and double their money.
i've got a little cable tv pre-amp from ebay could i hook that up to the 436 and see it does (see if i can replicate "that fault" ) so i will know for sure ?? wouldnt hurt right ?? or no
