 | The TR-5 is a
solid-state, broadband, SSB/CW transceiver which covers 11 amateur bands from
160 through
10 meters, including the new 12, 17 and 30 meter bands. The TR-5 offers
excellent sensitivity and selectivity, high dynamic range, digital frequency readout and
full break-in CW operation. |
| A front panel switch allows the operator to Select an
optional crystal filter independent of the MODE switch. A wide range of optional crystal
filter band-widths are available, and installation of an accessory filter can be
accomplished in minutes. The standard bandwidth is 2.3 kHz, and it is automatically
selected in transmit to insure proper signal characteristics. A passive double balanced
mixer is employed in the receiver front end. This stage is preceded by a low noise, high
dynamic range bipolar RF amplifier to provide good strong signal performance and weak
signal sensitivity. |
| The digital frequency readout of the TR-5
is derived from a true frequency counter to
assure an accurate display of operating frequency. In addition, the tuning knob dial skirt
is calibrated in 1 kHz increments to facilitate short frequency excursions. |
| The transmitter of the TR-5 features a rugged, solid-state power amplifier section which
has been de-signed for continuous duty in the SSB and CW modes. For more demanding duty
cycles, such as SSTV or RTTY, the Model FA-7 cooling fan is available. The transmitter
section also features very low harmonic and spurious output, and is equipped with
automatic high VSWR protection. |
| The VOX GAIN and DELAY controls are conveniently located on the front panel, and full
break-in CW operation is obtained via a switch on the VOX DELAY control. VOX operation can
be disabled by a front panel switch. |
| Other features include selectable AGC time constants, receiver incremental tuning
(RIT), provision for an accessory noise blanker (NB-5), and T/R switching connections for
an external linear amplifier and/or receiver. |
| The modular construction of the TR-5 reduces service time to a minimum. Each module is
designed to perform a specific function, and this feature, combined with the open,
accessible layout of the transceiver greatly simplifies any required alignment and
troubleshooting. Liberal use is made of table connectors, simplifying module removal.
