Dale...I believe it's called a "QCX". At least, that's what I built. ;) 73, Gwen, NG3P -- -+-+-+-+- Jenny Everywhere's Infinite: Quark Time http://quarktime.net

HI John, Up front I'm not familiar with that particular 'audio' filter, however, it has been my experience that 'add on audio filters' are connected via the headphone jack for use with headphones OR

David, KB1PJ, FWIW - you were the only station I was hearing last evening. No net, just you. I am curious if there is an actual net or is it just a watering hole for those who want to meet at a

I purchased and have almost completed the SSB Mite Filter but have not completed yet due to shortage of a 100k pot back that I have in my Florida inventory. The question: The manual on Page 2 implies

John, I may want to mod the OCX for SSB until I get the code down pat. I think a variable bandwith ssb/cw filter would be nice. Is your variable cw filter wide enough for ssb? If so, can you make

I'm not likely to mess with the cw filter on the OCX when it arrives and gets constructed. My HPM is going into my Century 21 rig. I just ran an analysis of the HPM on LTSpice. Steep, quick

David, Well, CW nets run the same as others and I have had it happen to me, anyone that can be heard that the NC can't should pick up the relay for you...… I believe that is covered in the NAQCC

Thanks for the welcome. You may have to wait a while to work me. The code practice is taking some time. Much easier when I was younger and taking the advanced test. Regards, Dale KS4NS -- Dale

qcx audio filter from CW to ssb es ft8 es WSPR / RX The QCX is already setup to TX WSPR (menu driven) but must be time synced with WWV to within +/- one srcond. The QCX can also be enjoyed as a

Those are useful guidelines. What if NC cannot hear you but others can. That has been, I think, one of my problems. By the way, I am in Portsmouth, NH. Maybe we have heard each other Sunday

Hi David, I’ll have to check your QTH and see where you are in relationship to me in Wells, Maine. I tried and could not hear much on 7.122 but I noted NC moved up so yet another lesson learned

Dale: welcome aboard. I am retired and often work up into Canada on CW/SSB QRP. Hope to hear and possible work you on the air some time. -- *72/73, Doc - K2PHD FN20qv - SKCC#5669 - NAQCC#9194 -

I have tried for months to join the net. Now I know you hear me. And I hear you. But it would be helpful if someone could describe the protocol for hams like me who are trying to join the net

I found the LTSpice files in the Folders. Now to play with LTSpice. -- Dale Hardin, KS4NS Elberta, AL

It's interesting that the 770 hz center frequency in that table has the same resistor values for a 750 hz center frequency as calculated by the spreadsheet I downloaded elsewhere. I have ordered an

I am an avid kit builder and have enjoyed building 4SQRP kits over the years. I didn't know there was an online group until just recently. I have built the QRPometer, NB6M HF Test Set, and have

I need some assistance with my effort to change the center frequency to 750 Hz. I have new resister values, but would like to have them confirmed with LTSpice. I understand someone in the group
