BULLETIN # 811
MODEL: TR-2400
SUBJECT: TR-2400 RX LOW, INTERMITTANT, or DISTORTED


For any of the above complaints, suspect a broken loose component in the RX
IF or audio output circuit on the RX TX unit.  Simply pull up on the leads
and resolder.

Adjacent to Q9, the audio output IC, find C49, a 1uf cap.  If broken loose
from the board, audio output may be down, while current consumption may be
up from the normal 30mA to about 100mA due to the audio output amp
oscillating.

Adjacent to L10, the discriminator, locate C33, a .033uf cap.  If this
component is broken loose, audio output may be up approximately 6 dB with
excessive high frequency audio response.
