Drake SW8

(0.0/5) Add a review / View all reviews

Desktop HF/VHF Receiver

The Drake SW8 is a portable communications receiver covering 100 to 30000 kHz in AM, USB and LSB modes. Quality reception of the AM broadcast band and all of shortwave is assured. Drake elected to include the FM broadcast band in the SW8 (87 -108 MHz). The extra heavy, forward facing speaker, along with a tone control, combine to offer pleasing fidelity. As a bonus, the VHF aeronautical band is also featured (118 - 137 MHz). Enjoy listening to commercial aircraft over-head, or even control tower transmissions if you live near an airport.

The impressive backlit LCD panel provides all the operational data you need to navigate this impressive receiver. Frequency display resolution is to 100 Hz on AM, shortwave and aircraft bands. The SW8 is a full fledged communications receiver, but it is also a true portable. The full size front handle makes it easy to carry. Please note that this handle can be conveniently removed by the user for stationary operation. The SW8 holds six D cells, and a pivot point 41 inch telescopic whip extends from the front for fully independent field operation. A 1/8th inch headphone jack is provided. Tuning is easy via keypad entry, manual tuning or memories.

For the shortwave and medium wave broadcast bands, a selectable sideband synchronous detector (SYNC) improves reception by reducing distortion due to fading signals. Other aids include: slow or fast AGC, RF attenuator and tone controls. Three IF bandwidths are supplied (6,4 and 2.3 kHz). Two independent clocks provide dual time zone selection and a 2 event timer turns the radio on at a prescribed time. Seventy non-volatile memories store: frequency, mode, bandwidth, AGC setting, RF attenuator and synchronous detector on/off. Memory channels may be accessed manually or through "time scan" with each channel monitored for 5 seconds. Keypad entry provides instant access to any frequency.

The rear panel of the radio includes a PL259-type antenna jack or wire inputs for shortwave. Spring terminals are also provided for an external FM/AIR antenna. Record output, and external speaker (4 - 8 ohm) jacks are also featured.
