RECEIVER: R127DF/R138DP
•
The R127DF FM 7-channel or the R138DP PCM 7-channel receiver included with your system is a high-sensitivity
narrow-band dual-conversion receiver.
•
Any Futaba narrow band FM receiver (all produced after 1991) on the correct frequency band and frequency may be
used with the 7C.
•
Any Futaba PCM 1024 receiver on the right frequency band and frequency may be used with the 7C (all 1024 receivers
say PCM1024; receivers which say PCM but not 1024 are 512 resolution and not compatible).
NEVER attempt to change a receiver's band by simply changing crystal (I.E. removing a 72MHz crystal and inserting
a 75MHz crystal). A receiver that has a crystal installed from a different frequency band without retuning will not
receive properly and will have dramatically decreased range.
•
In North America the receiver included with this system may have its frequency changed by simply changing the crystal
as long as it remains in the same half the band. A low band receiver between channels 11 and 35 may be changed to
any other channel between 11 and 35 without requiring any tuning. A high band receiver between channels 36 and 60
may similarly be changed. Receivers being changed from a high band channel to a low band or vice versa require proper
tuning and service by the Futaba Service Center.
