Rci Secrets; Ranger Rci-2950 - Ranger RCI-2950 Service Manual

Just want to toss a couple radio mods and secrets to You,and if any are fit to print-then please do so!!!
#1-RCI-2950>> R247 should be a 4.7k ohm resistor...the factory accidentally put in 47k ohm in some units...this will
hurt LSB performance if not corrected....
#2-RCI-2950>> R78 is a 2.2k ohm resistor...changing this to a 6.8k 1/4 watt resistor will improve receiver
performance in all modes,and help with the RF gain control operation as well
#3-RCI-2950>> R291 is the A.M. modulation limiter...removing this will boost A.M. only,and will not affect or cause
SSB overmodulation...
#4-RCI-2950>> To allow clarifier to slide in transmit and receive...Remove D59 and R197,take a 5" piece of
INSULATED wire and strip both ends,connect one end to the LEFT hole of the removed R197,connect other end to the far
right hole of the unused 4 hole box located to the right of Q33 and right behind D75...solder these 2 connections
carefully!!!
#6-Galaxy Rigs (models with the EPT360014B boards)>>To boost A.M. modulation,do NOT cut or remove TR-32!!!This
can adversely affect SSB,causing overmodulation and severe splatter!!!!The proper way to boost A.M.,is cut one end of
R249,and remove TR53 from the board..this will really boost the A.M.,but has NO affect on SSB..
#7-Galaxy Rigs>> A certain Service Manual(I will not name it as to prevent any lawsuits!!),incorrectly lists the proper
alignment cans for A.M. and SSB center frequency operation...Can L19 is the A.M. RX freq. adjustment,L20 is USB
adjustment,and L21 is for LSB...turning the wrong cans in that cluster of tuning cans will prove to make for a REAL BAD
DAY!!!!!!!

RANGER RCI-2950

Extended Frequency Modification: On microprocessor board locate the double two pin headers and shunt near the center
of the board. Move the shunt jumper to the other two-pin header right next to the original position. The new range of
frequencies is 26.000-29.700Mhz.
D87 & D111 are responsible for FM deviation. 10uF was installed across R308 for more deviation.
J54 was used as of a source for a transmit B+ signal that was routed through a small choke and then to the output SO-
239 connector to supply the amplifier with a multiplexed RF/keying signal.
