*. RX/TX indicator display
*. Dual independent band VFO selection (VFO A-B)
*. Rotary dial with 1-10-100-1K-10K-100K step option
*. Split operation (cross band)
*. 40 memory channel
*. Analog S-meter display
*. Audioscope display with disable option
*. RIT control
*. AGC/BW/NB control
*. Run Time IF value setting
*. Run Time BFO offset value setting
*. Run Time SI5351 correction/calibration value setting
*. 8 Programmable Band selector/control/setting (you may setup your own band)
*. Factory resetStandard 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.
- BritX exciter with additional audio band pass filter (assembled and tested)
- BritX build based on BITX transceiver design by OM Farhan VU2ESE, with additional audio processing and separate VFO and BFO signal generator. This board designed to worked with external synthesizer like RTC03 and RTC01C (see my other items below). BritX will work on all HF band with less sensitivity on the higher HF Band. With build in 1 watt RF pre-amplifier
- HBRF01 all band BPF/LPF, antenna switch and SWR pick up (assembled and tested)
- This module is a combo filter with All Band HF BPF, LPF, SWR pick up, and antenna switch consist of 5 wide band pass filter and 5 Low Pass filter
100 Watt PEP Max Power.
BPF consist of 3rd order shunt Band Pass Filter
- 1-2 MHz ………..160m
- 2-4 MHz ………..80m
- 4-8 MHz ………..40m
- 8-15 MHz ………30-20m
- 15-30 MHz …….17-15-10m
LPF consist of 5 pole Low Pass Filter
- 2 MHz
- 4 MHz
- 8 MHz
- 15 MHz
- 30 MHz
- 1-2 MHz ………..160m

- HBRPA20 (assembled and tested)
- HF Power Amplifier using low cost MOSFET (5 x IRF510) on driver and final. The Amplifier output depend on supply voltage and bias setting.
Its using generic design off push pull amplifier.*. This unit is assembled and tested on 40m (7MHz), with 20-22 watt output, 0.5 watt input, operate on 12V power supply, with dummy load
*. You may change voltage supply using step up (I do not sell the step up), up to 48V and get 80 watt output, but please used proper heat-sink and fan
*. The Power output will decrease on higher band
*. Beware when you want to adjust the bias voltage, improper operation may damage the MOSFET
