NE602 Si5351 OLED "Whole Foods" Receiver

This is one of those projects that sort of just happened.  First I built an Si5351/Arduino synthesizer with a small OLED I2C display (program by Thomas LA3PNA -- thanks Thomas).  Tom Hall AK2B up in New York helped me get the Si5351 VFO and BFO going -- thanks Tom.  Then, over the holidays I decided to build a rig of some sort around the Si5351.  I started with a superhet receiver using an NE602 as the mixer and another as the product detector.  I power the NE602 with an 8 volt regulator from W8NSA -- thanks Jim.  I made a 4 crystal 11 MHz Cohn filter using crystals left over from a BITX project.  The software from AADE helped me design the matching networks to match the filter to the 1500 ohm impedances of the NE602s.   I built the circuits on a milled board sent to me by Pete Juliano N6QW -- thanks Pete!   I put a dual tuned circuit at the front end, going into a MOSFET RF amplifier.   For audio amp I have an LM386.  The whole thing is screwed down to a barbeque grilling plank from Whole Foods -- thanks Whole Foods!  (This seems appropriate -- the "O" in OLED is for "Organic"!)

It sounds nice.  I may eventually try to put some relays in to switch the NE602s and the filter around to make this a transceiver.
