RTC03 HF Transceiver Controller with Si5351 Freq Synthesizer VFO/BFO + Enclosure
This listing is only the Controller and Enclosure, you still need to add Exciter, Power Amplifier, LPF/BPF to do communication,
RTC03 is the newest version of radio transceiver controller (RTC) Jalapindai/Homebrewpartner. This RTC version used Si5351 as frequency synthesizer and used 2 of 3 output on the chips. SDR mode with 4x VFO out vs frequency display also supported covering all HF band (4-120MHz out covering 1-30MHz HF band ). CB channel (require band setting) also supported by this module. Beside VFO out, this module given BFO frequency according to IF and SSB offset setting. Onboard button and Rotary Encoder made this module easy to applied on to your existing exciter such us BITX, Ararinha and other, heterodyne or direct conversion method.

Standard band coverage (programmable)
160m = 1.800 MHz – 1.999 MHz
80m = 3.500 MHz – 3.999 MHz
40m = 6.900 MHz – 7.249 MHz
30m = 10.100 MHz – 10.149 MHz
20m = 14.000 MHz – 14.349 MHz
17m = 18.068 MHz – 18.168 MHz
15m = 21.000 MHz – 21.449 MHz
10m = 28.000 MHz – 29.699 MHz
You may adjust the band min and max frequency later (HF band)
You can ask me to replace 12m instead 160m so the band list is 80m, 40m, 30m, 20m, 17m, 15m, 12m, 10m.
