New firmware version ver.2.50b is available now in download section which reveals use of a new AF optional board – digital DSP audio filter board. Ver.2.50b is first step to the new DSP features of the radio. With new Ver.2.50b

I am very excited to share with all friends that we just finished tests of our new plastic mould die for RGO ONE knob sets. Making this was very very long and cost consuming process but finally we are ready

Many thanks to Kent Trimble K9ZTV who made excellent detailed instruction for RGO ONE FLASH UPDATE procedure. PDF file is available in downloads section here He emphasized on key moments of selecting RGO ONE profile – for front panel and

New firmware ver.2.41A is available. CW waveform clipping and LPF hot switching problem when lower delay time (menu 41 trd) is selected is now resolved Files for software update are located in download section FW2.40A

Today I made real video of Noise blanker performance and how FT-DX10 and RGO ONE fight against strong pulse spikes. Side by side comparison. Tried best values for NB parameters for both radios. Signal mix is routed via coaxial switch

NB manual is available in download section here

This software version implements new optional NB module features.NB noise blanker/noise receiver optional board gives ability to remove pulse noisesfrom man-made home/industrial appliances, electrical power lines etc.QRN and other atmospheric noises with long pulse duration might not be suppressed effectively.

This is simulation in real situation and how NB module interacts on useful receiving signal. Is there any artifacts of its action.. Please comment. For the test have been used the following stuff: Siglent waveform generator and Mini circuits two

RGO ONE Noise Blanker (noise receiver) demonstration. Input noise pulse spikes are simulated by Siglent arbitrary waveform generator. Frequency 14MHzPulse signal duration 80 periods (sinusoids)Silence duration 100 mili secondsInput amplitude 0dbm (>600mV) In other words injecting at receiver input very

New firmware is ready – 2.39b. Here are key points: Better CW performance in QSK and delay mode. Straight key/PC/DTR keying improved. New menu entry added – MENU 41. Adjustable TX (prequel) time from 6-18msec. QSK and non QSK amplifiers
