Hi Group

We are building an autonomous Relay-Station for PBR using the Dataradio
RNet-JSLM Transceiver.

The Application this unit is intended to be used in has some sort of remote
control functionality, whereas the frequency of some control tones is as low
as 123Hz. We need to transmit these tones transparently through a system
consisting of two of the mentioned untis without any loss of NF power. We
noticed while using the Tx-/Rx-Auxiliary Data Path that there must be some
high pass filter applied, which prevents from getting these low control
tones
through the system.

Does anyone know if NF Frequency response of these Modules can be tuned in
order to pass our control tones ?


Thanks in advance
