The Harris RF-5020 is an HF Receiver-Exciter covering 1.6 to 30mHz
in 10Hz steps when operating from the front panel. 1Hz tuning
steps are available through the serial control interface. Power
input is 26.4 VDC nominal @ 3amps max. Power out is 100 milliwatts
nominal across the range, suitable for driving a wide range of
military RF amplifiers, including the matching Harris units, the
Redifon GA-481 (which I use), the AM-3007/URT (part of the URC-35),
the AM-3349/GRC-106, and the Technical Materiel Corp GPT-1K
and PAL-350 to name a few.

This radio has a digital I.F., with DSP processing employed
during both receive and transmit. Available modes and selectable
bandwidths associated with each mode a

USB/LSB -- 1.5, 2.0, 2.4, 2.7, 3.0kHz
AME -- 3.0, 4.0, 5.0, 6.0kHz
CW -- 350Hz, 680Hz, 1.0kHz, 1.5kHz
Modem and Digital Voice -- 3.0kHz

The BFO function is variable +/- 4kHz in 10Hz steps from the
front panel or in 1Hz steps through the serial interface.

AGC attack/hang/decay data is as follows for settings other
than "OFF":

FAST - 25msec/100msec/100msec
MEDIUM - 25msec/500msec/750msec
SLOW - 25msec/1500msec/1500msec
DATA - 25ms/0msec/16msec

This unit has the following options installed:

RF-5110MD High-Speed Data Modem. In the high-rate 39-tone mode,
a channel transmission rate of 3466bps is achieved by time
differential phase shift keying (TDPSK) of 39 tones which
is combined with forward error correcting to produce data
rates ranging from 75 to 2400bps. The modem is used during
digital voice operation.

RF-5120AFC Harris ALE Automatic Link Establishment. Please
note this is the Harris proprietary "Autolink" ALE system.
It will work with other systems containing the same option
but not with the MIL-STD-188-141 ALE most often encountered
on the ham bands. The solution in that case is to set up
PC-ALE on your PC. :-)

RF-5130LPC Digitized Voice. Uses the U.S. DoD LPC-10E (Version
52) 2400bps algorithm.
