VGA applies to both HF and VHF. Use the newer generation of tuner chip R828D instead of R820T2.
Use an enhanced version of 64M LPF to improve image rejection further. A jumper can select the internal reference clock or an external 27Mhz reference clock.
The primary motivation is giving users smaller granularity control on the RF front-end and a big dynamic range to fit the demands of both strong. The tunable range is -41.5dB to +33dB for HF and 0db to 55dB for VHF, which covers most use cases.
During the MKII development, we are working very closely with the original author of BBRF103, IK1XPV, on his new universal driver. RX888 and RX-888 MKII now.
And we expect the power of opensource will significantly improve the software support and the lifetime of RX888. LTC2208 16bit ADC at 130 MSPS. Dual RF input, HF frequency range: 1kHz-64Mhz, maximum real-time. VHF frequency range: 64M-1700Mhz, maximum real-time. ATT adjustment range -32dB to 0dB.
