Blocking dynamic ranges: 20kHz offsets 123dB,2kHz offsets 78 dB
Package size: 265 * 153 * 90mm / 10.4 * 6.0 * 3.5inch
Package weight: 698g / 1.5lb
Features:
- 8 band coverage 80m/60m/40m/30m/20m/17m/15m/10m and can reach 3-5W power in 8 bands and reserve TO-220/SMD(ILRI2060) pads required for upgrades.
- High emission efficiency, 80m/60m/40m/30m/20m efficiency is higher than 85%,/17m/15m efficiency is higher than 80%, 10m efficiency is higher than70% and frequency accuracy is better than 1ppm,frequency stability is better than 0.5ppm.
- Independent main board and RF board to avert own signal interferences, and small enough to fit even in your pocket and easy to travel with.
- It has I/Q output pin header on printed circuit board which can be extended with a 3.5 mm jack cord to connect a PC soundcard audio line input to decode with various software as any dongle.
- It has a PTT OUT jack driven with a Solid State opto coupled relay capable of driving 500 mAh relays for example an external RF Power Amplifier relay directly.

- SSB opposite side-band/carrier suppression Transmit:better than -45dBcs, IMD3 (two-tone) -33dBcs,Receive:better than -50 dBcs.
- Multiband support,continuously tunable through bands 160m-10m(and from 20kHz..99MHz with loss in performance).
- Software-based VOXs that can be used quick FullBreak-IN(QSK and semi-QSK operation) or assist in RX/TX switching for operating digital modes(no C-AT or PTT interface required),external PTT output/PA control with TX-delay.
- Fully digital and software-based SSB transmit-stage:samples microphone-input and reconstruct a SSB-signal by controlling the phase of the SI5351 PLL(through tiny frequency changes over 800kbits I2C) and the amplitude of the PA (through PWM of the PA key-shaping circuit).
- Three independent switchable analogs front-end receiver attenuators(0dB,-13dB,-20dB, -33dB, -53dB,-60dB,-70dB).
