My new project: SDR Angelia  4th generation DDC/DUC + PA 300W.

ANGELIA is a state-of-the-art soft core uP 4th generation DDC/DUC, Hermes-like, transceiver board that incorporates an Altera Cyclone IV FPGA and dual LTC2208 ADCs. The large FPGA and dual ADCs permit exceptional versatility and performance. The FPGA is large enough to allow on-board, soft-core processing, if desired, and the dual ADCs allow true coherent receiver operations.

                   Angelia board -complete hf + 6 m SDR  transceiver  500 mW out                       Band pass filter for Angelia

Design front panel and rear SDR

My  hf all band pa  eb300 300 W for Angelia SDR

My new projects:

LDMOS Power Amplifier 1.8-54 Mhz for 2xBLX188XR

My ESSB setup : Logic Pro X on iMac 27'' and hardware .  

As the eSSB definition above states, it is an "Extended" version of SSB. The radio frequency and audio frequency footprint (bandwidth) is extended as a result of several factors; I.F. filter modifications, and/or Digital Signal Processing, and external audio pre-emphasis processing via Equalizing, Compressing, Peak-Limiting, etc. of the source audio input.
