——————————————————————————————————————————————————————————————

The SW-6B is a six-band CW QRP transceiver with simple and practical features and straightforward operation, making it the best choice for field setups, outings and other activities.

 

* Two version available,one is with matel enclosure,the other is with plastic enclosure,while all the hardware and functionalities are same. *

 

Specifications:

Case size: Approx. 160mm by 110mm by 55mm / 6.3 in by 4.3 in by 2.2 in.(Metal case)

Approx. 170mm by 120mm by 72mm / 6.7 in by 4.7 in by 2.8 in.(Plastic case)

Weight: Approx. 520g / 1.14 lbs, (approx. 660g / 1.45 lbs) when the 3-cell 18650 Li- ion battery is installed)  (Metal case)

Approx. 480g / 1.05 lbs, (approx. 620g / 1.37 lbs) when the 3-cell 18650 Li- ion battery is installed)  (Plastic case)

Operating voltage: 10-14VDC, reverse polarity protected.

Current consumption:

Receive – ~70mA (internal speaker off) or about 100mA (internal speaker on) NOTE – Current draw varies with volume setting.

Transmit: 0.7 to 0.8A (@ 12VDC)

Frequency Range: Receive:

(1) 3-5MHz, (2) 5-6MHz, (3) 6-8MHz, (4) 8-16MHz, (5) 16-22MHz.

(receive sensitivity peaks at 80m, 60m only)

Transmit:

(1) 3.5-3.8 MHz/80M, (2) 5.35-5.368 MHz/60M, (3) 7.0-7.2 MHz/40M, (4) 14.0-14.35 MHz/20M. (5) 18.068-18.168 MHz/17M, 21.0-21.45 MHz/15M (shared 17M & 15M).

Filter: CW/CWR, SSB in two steps with automatic switching. CW filter bandwidth ~400Hz, SSB bandwidth ~2KHz.

RIT/XIT Adjustment:

RIT: -9KHz to +9KHz  in 10HZ steps. XIT: -30KHz to +30KHz in 100HZ steps.

Output power: ~5W (@ 12VDC input)

Side tone 600Hz

Keyer: Built-in keyer speed is adjustable from front panel with a control.

Memory: There are 8 memories for each band, and the frequency and operating mode set by the user

NOTE – 17m and 15m share a common band/memory location.

Receive modes:

CW, CWR, USB, LSB.

NOTE – You may transmit CW signals when in SSB mode, thus enabling CW/SSB cross-mode operation.

AGC: Audio derived AGC

S meter shows the relative strength of the signal for reference only.

Connections

External power supply and internal battery connectors:

Any stable, clean 10-14VDC source may be used via the 5.5mm x 2.1 mm power connector. There is space for an internal battery, a three-cell 18650 lithium battery pack (voltage 11-12.6V).

If the internal battery is installed, you may stil use an external power supply. The voltage of the

external power supply must be higher than the voltage of the built-in battery.

If the external supply voltage is lower than the voltage of the built-in battery, the radio will use the built-in battery power supply, even though external power is supplied.
