I'm presently setting up 4 Delta SX UHF Transceivers as Tx'ters for a
repeater system. I have completed the mod and am presently trying to
tune radios. The problem I'm having is that my dev is up to about 9.8
kHz. My service manual says to adjust R237 (Dev Adj). The radio that I
am working on does not have R237. The Deltas that I have were in use in
Canada by the RCMP and purchased as surplus. I built an Eeprom writer
which appears to work okay. I also installed a four dip s/w to allow me
to use 16 channels. The freq I programmed are 420.xxx and the Delta is
a 403-430 MHz 35 W. For my application I have decreased O/P to 10 W. My
freq error is less than 200 Hz. Anyone know how to adjust Dev without
R237. I'm not new to electronics as I was a sonar technician in the
Canadian Navy for 21 years but I am very new to 2 way radios. Any help
would greatly be appreciated.
