The Si5351a/b/c are one such a family of parts that provides 3 programmable oscillator outputs in a small 10 pin TSSOP package.

Silicon Labs has now produced a series of well-performing oscillators that solve this challenge trivially : You connect the oscillator chip over a pair of I2C lines and it is done. It satisfies for regular work, a few trips to the field as well.Ī key challenge for multiband transceivers has been to realize a local oscillator system with such wide range. This rig has been in regular use on forty and twenty meters for a year at VU2ESE. It is a compact, single board design that covers the entire HF range with a few minor trade-offs. While achieving competition-grade performance from a multiband homebrew transceiver is a complex task, as evidenced by the works like that of HBR2000 by VE7CA, it is not at all difficult to achieve a more modest design goal with far lesser complexity. Over months, I realized that the need for a general coverage HF transceiver was wide-spread among the homebrewers.

The KISS mixer of the Minima, though a very respectable receiver front-end, had serious leakage of the local oscillator that caused that design to be abandoned as a full transceiver. A few years ago, I attempted a high performance, multi-band architecture with the Minima transceiver. I ended up buying an FT-817ND that has been a reliable old warhorse for years. On the other hand, many of the homebrewers do need a general coverage transceiver on the bench as well as as a base transceiver for bands beyond the HF.

The Software Defined Radio (SDR) route as followed by several designs offer some simplification at the cost of bringing digital signal processing and a PC into the signal path. There have been some remarkable successes in the past, the CDG2000 (designed by Colin Horrabin G3SBI, Dave Roberts G8KBB and George Fare G3OGQ) is one such design.

Homebrewers have traditionally avoided making multiband transceivers as they can get extremely complex and difficult to make.
