Equipment Reviews, September 1999

The NASA HF-4 Communications Receiver

I don’t know the background to the name changes, but the NASA HF-4 is clearly a refined version of the Target HF-3 receiver that I reviewed in the April, 1997 Journal. The HF-4 is now distributed by Deltron Communications International.

For those who who have access to the HF-3 review, I’ll list the changes made in the HF-4. The major changes are: the inclusion of a 2.6 kHz filter in addition to the original 6 kHz filter, a lighted display panel, expansion of the available memory channels from one to ten, addition of a RS232 jack to permit reception of weather fax transmissions (PC software and cable included) and substitution of a SO-239 antenna connector for the RCA jack used on the HF-3. In addition, there is a back-panel slide switch to apply 12 volt DC power to the antenna connector to be used with the NASA AA-30 active antenna or any other active antenna that can be remotely powered.
