[Novice-Rigs] REDUCED: Drake TR3 Transceiver

[Bry Carling]

FOR SALE: Drake TR3 Transceiver

R. L. Drake model TR-3 is an SSB-CW-AM transceiver designed for the 
transmission and reception of upper and lower sideband signals on the 80 
through 10 meter amateur bands. AM and CW capabilities are included.

Ideal for both fixed station use in conjunction with the model AC-3 or AC4 
120 volt AC Power Supply, or for mobile installations using the DC-3 or DC4 
12 volt DC Power Supply.

The 300 watt PEP input on SSB enables the TR-3 to give an excellent 
account of itself barefoot and it will drive the highest powered ham linear 
amplifiers.

Upper and lower sideband selection is accomplished by switching between 
two Drake designed and manufactured 9 MC crystal lattice filters with 2.1 kc 
pass-bands. Among the other features included on the TR-3 are VOX and 
PTT, shifted carrier CW, separate RF and AF gain controls, linear 
permeability tuned VFO with vernier scale, transmitting and receiving AGC, 
and separate receiver S-meter and transmitter plate ammeter. The addition 
of the accessory RV- 3 remote VFO speaker combination enables the 
operator to receive, transmit or transceive throughout the band being used 
without disturbing the setting of the TR-3 tuning dial. This is useful for 
working DX stations operating outside the United States Phone Bands, or 
for working near your own frequency in search of a clear spot under 
crowded band conditions.

FREQUENCY COVERAGE:
Full coverage on all amateur bands 10 thru 80 meters, in seven 600 k c 
ranges ; 3.5-4.1 mc, 7.0 to 7.6 mc, 13.9 to 14.5 mc, 21 to 21.6 mc, 28 to 
28.6 mc, 28.5 to 29.1 mc, 29.1 to 29.7 mc. bullet LINEAR PERMEABILITY 
TUNED VFO: Tunes 4.9 to 5.5 mc for all ranges, 9 mc I.F. minus VFO 
range overs 80 meters, 9 mc I. F. plus VFO range covers 20 meters. VFO 
and crystal oscillator heterodyned in premixer for 40, 15, and three 10 meter 
ranges.

DIAL CALIBRATION:
10 kc divisions on main tuning dial and interpolation to 1 kc on tuning knob 
skirt . Effective length of circular dial scale is over 14 inches.

FREQUENCY STABILITY:
High stability permeability tuned VFO tunes same range on all bands . Drift 
is less than 100 cycles after warm-up, and less than 100 cycles for plus or 
minus 10% line voltage change.

FRONT PANEL CONTROLS:
Main Tuning has fluted knob with adjustable 25 division skirt. Tunes VFO 
and rotates main dial.
RF Tune tunes the RF circuit common to receiver RF amplifier and 
transmitter driver stages. 0-10 scale.
Plate and Load tuning adjust pi-network capacitors in transmitter for proper 
resonance and loading on each band.
Band switch selects desired ham band (see frequency coverage).
Function switch has four positions CAL, SSB, X-CW, X-AM. CAL operates 
built-in 100 kc crystal calibrator for accurate setting of main tuning hair line 
indicator and knob skirt SSB provides SSB operation, either VOX or PTT, 
and is receive position for SSB, CW, and AM. X-CW (transmit CW) inserts 
carrier , converts `Xmtr Gain´ control to carrier injection for tuning and CW 
transmitting. X-AM (transmit AM) inserts carrier and screen modulator for 
AM transmitting.
XMTR GAIN functions as mike audio gain on SSB and AM, and as carrier 
injection control on X-CW for tune and CW.
RCVR GAIN knob controls receiver AF gain and power ON-OFF switch. 
Lever behind knob controls setting of RF gain.
Sideband switch in conjunction with indicator lights marked Upper and lower 
selects desired sideband by connecting into the circuit either the upper or 
lower sideband filter. 

There is no power supply with this radio.
