SPECIFICATIONS
Band Coverage:
160, 80, 40, 20, 15, and 10 (export only) meter
amateur bands. 10 meter also useable in USA with
proof of license and user modification.
WARC Band Coverage:
The HF-3KDX has not been designed to operate on the WARC
Bands. This occurs because there are not enough bandswitch
positions to accommodate these bands. You will get some
amplification on 17 & 12 meters using the 15 and 10 meter
band positions. However, you will not get amplification on
30 meters.
Drive Power Required:
50 to 80 watts nominal for rated output
Maximum Output Power:
1,500 watts peak all modes including SSB, CW, and continuous carrier
or modulated carrier. Carrier operation (RTTY,FM, or SSTV) for more
than 30 minutes requires use of auxiliary cooling
Power Gain:
Nominally 14 db
Automatic Limiting
Control (ALC)
:
0 to -20 Volts negative going, adjustable from Front Panel
Harmonic Suppression:
Meets F.C.C. Requirements
Keying:
Requires relay contact closure or sink of 80 ma @ 12 VDC
or +15 VDC on transmit supplied by transceiver
Input Impedance:
50 ohms unbalanced, VSWR <1.5:1
Output Impedance:
50 ohms unbalanced with SWR 2:1 or less
Tube Requirement (1):
8877/3CX1500 Triode
Power Line Requirement:
