V 2.0 of the Simpleceiver Plus SSB Transceiver
So OK many of our builders are still in the process of collecting parts for
the Direct Conversion Receiver version (that was three configurations ago).
But just in case you are ready for the next (and final) iteration of this
project here we go. Version 2 -- What is it? V2.0 is the Simpleceiver Plus
SSB Transceiver Architecture with the following changes: A GRQP Club 9.0
MHz Crystal Filter is used in place of the homebrew 12.096 Four Pole
Filter. This gives the advantage of acquiring the matching crystals for the
BFO and with a 5 MHz Analog VFO you can have a two band rig (20 meters or
80 Meters). The only change required is the appropriate matching Band Pass
and Low Pass Filters. A couple of relays and a toggle switch will put you
on either band. So a big plus here. Or you can leave it on 40
Meters.Compacting the rig in physical size. I have used two 4 X 6 inch PC
Board and fit all of the circuitry on these two boards which will then be
stacked upon each other. The main board has the Band Pass Filter, the RxTx
mixer (ADE-1), the IF block module comprised of two amps and the filter
with the relay switching network, the ADE-1 Product Detector/Balanced
Modulator, the Microphone Amplifier and the Audio Amplifier. The upper
(second) board will have the RxTx RF Amplifier, the driver stage and the
IRF 510 Final, Low Pass filter and the TR relay switching scheme.The
Si5351/Arduino/Display will be mounted to the front panel.The finished size
should be about 4.5 Inches wide, about 9 inches deep and about 3 inches
high. This is not a miniature rig but certainly small and will be painted
Oasis BlueHere are some photos of the work in progress: The grid in the
lower left hand corner is for the Microphone Amp and the grid in the lower
middle is for the Audio Amplifier. There are some blank spaces on the board
where the switching relay will be installed
