Current Status:   ON 

Location:  this DX-Tuner is 17 KM SSW of Caracas City, and 3 Km SW of the town of San Antonio de Los Altos, at 1484 meters asl.
 

Receiver ICOM PCR-1000

The ICOM PCR1000 wideband computer receiver has an great coverage with reception from 10 kHz to 1300 MHz (less cellular). Modes of reception (and bandwidth) include AM (15/6 kHz), FM-Wide (230 kHz), FM-Narrow (15/6 kHz), SSB (2.8 kHz) and CW (2.8 kHz). A triple conversion circuit ensures good performance over the entire range. Shortwave sensitivity (1.8-28 MHz) is an impressive 0.28µV.

Antennas:   

VHF/UHF Antenna:
 Discone located at 13 m above ground.
The lenght of cable between the discone and the receiver is 14 m, and is connected via a Stridber Engineering model MC204 VHF/UHF Receiver Multicoupler (25 MHz - 1 GHz) via a Optoelectronics FM Broadcasting band trap. This antenna is shared with the San Antonio DX DX-Tuner via the mentioned multicoupler.

HF Antenna:
Assymetric dipole (default antenna)
 The dipole is located at  13 meters above ground.  See the table below for the actual HF antenna currently connected to the receiver. The HF antenna in use is shared with the Caracas DX Tuner. via a Stridberg Engineering model MCA104 Receiver Multicoupler (100 KHz - 50 MHz).

Please report any frequencies  on this DX-Tuner to yv5fih  DOT arrl.net to update the band guides. 


Current HF antenna:   1

 
                                    1.- Assymetric dipole 90 meters total length assymetric straight dipole (75 m of 21 AWG sloped & 15 m of 10 AWG horizontal). The 75 m extreme ends at 3 m above ground and the 15 m extreme ends at 13 m above ground). The central connector is at 13 m above ground. The assymetric dipole is oriented for maximal reception at 15 degrees (NNE) . The 75 m extreme is at the NNW side, and the 15 m extreme is at the SSE of the dipole. The lenght of cable from the dipole to the radio is about 9 meters.
