SW-3B is an ultra-small, ultra-lightweight three-band CW QRP Transceiver that consumes less than 40mA when receiving.
It is ideal for portable use, Field Day and SOTA.
Dimensions: 104*71*25mm (excluding the protruding part such as knob)
Weight: 180g. Operating voltage:8-15VDC.
Operating current: Receiving: about 45mA(backlight on), and less than 40mA(backlight off) : Transmitting: about 0.8A (at 12V voltage).
Frequency range: 5-8MHz, 8-11MHz, 11-16MHz (the receiving sensitivity peak is only 40m, 30m, 20m amateur band) : Transmitting:7.0-7.2MHz, 10.1-10.15MHz, 14.0 -14.35MHz.
Two filters: CW and SSB are automatically switched according to the operatingmode. The CW filter hasa bandwidth of about 400 Hz and the SSB is about 2 kHz.
The adjustment range of RIT/XIT RIT: -9KHz to +9KHz, XIT adjustment range:-30KHz to +30KHz. Output power is Approx..5W (depending on power supply voltage. Nominal is 12V)
Side tone: is set at 600Hz
Auto keyer: The built-in auto keyerspeed is adjustable. Storage: Each band has 8 storage frequency channel, and the frequency and operatingmode can be stored by the user arbitrarily.
Receiving mode: CW, CWR, USB, LSB. It can also be transmitted in the SSB mode of receiving, enabling cross-linking of CW/SSB.
AGC: Simple Audio AGC, S metershows the relative strength of the signal and is for reference only.
