SDS100/SDS200: SDS 100-Failure of dark screen ( with LED flashing) to illuminate properly on some FIRST transmissions.

[k3rsj]

Audio remains normal throughout entire transmission, while the screen doesn't illuminate at all during transmission, or blanks out prior to transmission ending. Audio remains normal and LED blinks appropriately for either situation. Only observed on MD FIRST and AA County PD (new P 25) systems. Appears to have started with latest software updates. NOTE-These are NOT encrypted channels and signal strengths are strong.
Joe Bearcat please take notice.
