Jack, did you ever send out details on how to store the cal data on the SD Card?? I can't figure it out.? My SD Card shows "no files" when I connect it to my PC.? I know that you are at FDIM, so no

Hi All - I hooked up 3 brand-new D cells and got 4.81V.? I measured 3 cases, as shown on the graph.? It included the new battery case, as well as 10mH feeding a 100 uF ceramic.? They all look the

Larry, thanks for the pointer. The UHFSDR design is highly informative. j

You gonna be at Hamvention? If so, stop by Booth #2607. Al may be there too depending when people come. Dr. William J. Schmidt - K9HZ J62K(J68HZ) 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner -

John, look up UHFSDR (WB6DHW design ) for another approach. I built one, have another in a partly built state. It works well, I get UHF performance. I paired it with an EdenDSP 3.0 board. Larry KB3CUF

Hi Bill, I would love to see your simple design. I too have thought about replacing the '3253 with discrete FET switches, but getting very fast switching speed *and* suitable RF performance appears

No one seems to consider this but you COULD build analogs of these devices using high frequency discrete parts. I have something like breadboarded as a replacement for the mixer… it works but needs

I think that changed again. Seems to change from day to day at this point. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch – K9ZC

Gary, I'd like to try one of your boards, if you have any left. Let me know how to proceed. -- This email has been checked for viruses by Avast antivirus software. www.avast.com

Hi Gary, I'm game for one (maybe two) board(s). Contact me off-list and maybe we can help each other out... Thanks!73,Vern N7GTB (at yahoo)

Hi Bob and all By way of introduction, I'm a local friend of Bob's, WA7EXH since 1965, and a reader of this group. Bob, since I last talked to you about this, it's occurred to me that most of my

Hi Phil- I don't know if there is a performance difference between QSE2DC and the V12 circuit.? There is insufficient data available for comparison. Yes, carrier nulling is a software task which has

Hi Greg Is there any difference in performance of QSE2DC and the V12 circuit other than the nulling capacity? Nulling is a software task? I notice your use of the differential "op amps" for the

Hi John Looking forward to your performance results... I haven't yet built an RF board, been stuck on toroids and other things, so would consider your RF board. Regards Phil VK2KKZ
