Introduction
RGO ONE is classic superheterodyne down conversion HAM transceiver covering all
HF bands 1.8 - 29.7MHz (160/60m as an option). Due to its modular construction it
can be easily modified or redesigned in manner that suits operator. This kit is
intended for users that like building their own home made equipment and
constructions.
Here are some of the feature highlights:
QRP/QRO output 5 – 50W
All mode shortwave operation – coverage of all HAM HF bands (160m/60m optional)
High dynamic range receiver design including high IP3 monolithic linear amplifiers
in the front end and diode ring RX mixer or H-mode first mixer (option).
Low phase noise first LO – SI570 XO/VCXO chip.
Full/semi (delay) QSK on CW; PTT/VOX operation on SSB. Strict RX/TX sequencing
scheme. No click sounds at all!
Down conversion superhet topology with popular 9MHz IF
Custom made crystal filters for SSB and CW and variable crystal 4 pole filter –
Johnson type 200…2000Hz
Fast acting AGC (fast and slow) with 134kHz dedicated IF
Stylish and professional look
Compact and lightweight body
Custom made multicolor backlit FSTN LCD
Custom molded front panel with ergonomic controls.
Silent operation with no clicking relays inside - solid state GaAs PHEMT SPDT
switches on RX (BPF and TX to RX switching) and ultrafast rectifying diodes (LPF)
Modular construction – Main board serves as a “chassis” also fits all the external
connectors, daughter boards, inter-connections and acts as a cable harness.
Optional modules – Noise Blanker (NB), Audio Filter (AF), ATU, XVRTER
PC control via CAT protocol; USB UART - FTDI chipset
Double CPU circuitry control for front panel and main board – both field
programmable via USB interface.
Memory morse code keyer (Curtis A, CMOS B); 4 Memory locations 128 bytes each
Contest and DXpedition conveniences – XFC function in SPLIT, RIT/XIT function
