I had been sworn to secrecy for so long, I thought I was going to burst. I almost hinted at this in the last podcast. But I didn't. I kept the secret. But now Farhan has made public his latest creation:
Wow! Great stuff from Farhan. I love reading his circuit notes even though much of it passes right over my head.
He has such a good-natured approach to circuit design and his projects are practical and sensible in regards to performance, ease of construction and component choice.
Great job Bill on keeping the secret...there was a sly mention on the 10th anniversary Podcast of how long it had been since Farhan had visited the show, which makes me think the subject of this special project was slowly percolating towards the surface.
I so want to build this. I have a couple of CMOS Si570s left over from building SoftRock RxTx 6.3 and other SDRs. Too bad it won't work since it can only go up to 160MHz. :( However, I'm already developing my own DDS front end with a PIC microcontroller. Would be easy to swap it out with one out of the junk box that can connect to the PC with USB. Never had a reason to buy an Arduino yet. With the source code available, I'll probably stick with my own front end to save some money. Not counting PCB materials, I think I can build one for under $50 (also not counting junk box parts). What's a good source for inexpensive PCB for RF projects?
Having finished up my QSK VFO system for vintage Knight T-50 and Drake 2B (the latter being entirely Bill's fault), the bench is empty and needs a project. A spectrum analyzer to analyze crystal filters has been needed in my shack for a long time. The Arduino has now made this possible with low cost and high accuracy. Wow, Farhan. Obviously, it's time to start planning this next project! Congratulations.
In response to popular demand, "SolderSmoke -- Global Adventures in Wireless Electronics" is now available as an e-book for Amazon's Kindle.

The two versions are identical, except for a minor difference in the paper used. That's why the prices are a bit different.
