You can do both the above in a base station configuration or you will need both reeds if the card is for duplex (repeater) operation. The TRN5073A is Duplex (TA-RB) TRN5074A is Simplex (TA-RA) The TRN5075A is Simplex (TA-RB) > 2. Which socket is the tx and which is the rx socket? You or I would simply have to look it up in the manual... Since it's friday... decoding reed Z1 (for TA-RA) and Z2 (for TA-RB) on duplex applications. So you probably want Z1 as the encode reed and Z2 as the Decode reed. > 3. Does anyone have a scanned image of the PL board schematic and/or > jumper listings?
