Gentlemen- A couple of young hams have expressed interest in building this excellent meter but I'm unable to find a source for the PC boards. I have a copy of the PIC compiled code that I can share with them but need to source the boards, or get my hands on the gerber files so some can be produced. FAR circuits does not list the boards and it appears that Kangaus is not fully operational. Does anyone know where either boards or the gerber data can be acquired?

Phil, Consider the board set that was produced by the Poor Hams Scalar Network Analyzer (PHSNA) Yahoo Egroup. Rather than using the PIC code that Roger did, it uses an Arduino Uno. The power meter is a separate board for use with the system of generator (an AD9850 or 9851 module), and processor. Contact the group, or Jim, emrfd@yahoogroups.com for current status of boards available. As useful as the power meter is, in a system forming a SNA, it's really a powerful tool. I do have one set of boards for the WA7EXM power meter that I once planned to build, but have moved on to other instruments for the same purpose. I'll pull it out if you want it, but I have only one set, un-built. Let me know if I can help. 73, Ed - N5EM 10258

| I can help develop the gerber etc. if you have the schematic. Also, a clean scan of the existing PCBs (both sides) can be used to manufacture the boards using the toner transfer approach. PCB etching using laser printer

| Ed- Thank you for your response. I'd be interested in buying your set of boards if they are available. You can respond directly to me sittners@sbcglobal.net. I can likely generate a duplicate layout for other some of the other guys. Phil
