Subject:  Receiver Degrade Over Time

My PK-232MBX was slowly going deaf. The transmit was okay, but I was having
trouble receiving packets. I would connect to a station and get good ACKs, but
was having trouble printing them and since I was not receiving their packet,
they would time out waiting for me to ACK. This problem did not happen over
night but seemed to degrade with time.

Called AEA and the technician suggested I change out the U-20 MC-1488. I used a
Radio Shack 276-2520 Quad Line Driver. It worked! I have to admit it was not
easy to remove the ol
If your PK-232 seems to be going deaf, consider replacing U-20. Much thanks to
AEA for the tip. Saved me having to send the PK-232 off for repair.
