Re: Exploring the 4SQRP Group "Member Map" tab John Lonigro #20293 Good tip Jeff. The member list is alphabetized so you really don’t need to do a search at all, other than rapidly scrolling down the list and doing an old fashioned visual search. 72, John, AA0VE toggle quoted messageShow quoted text On Aug 14, 2019, at 6:03 AM, Jeff Logullo N0̸MII <jeff@...> wrote: One exception to Jim's tip below: if you're trying to search for a "0" (numeric zero) your browser search will fail.

Re: The Lightbulb QSO Party Nick Kennedy <kennnick@...> #20285 I always figured that with the light bulb thing, most of the radiation would be from the coax. But maybe not. There was an article in QST years ago (July 2000) called "Everything Works" where a guy made QSOs using a light bulb for a load. It was a much better period for propagation though. I found it on line here: https://www.okdxf.eu/files/everything_works.pdf At OzarkCon this year I used a 50 ohm resistor inserted into a small loop of wire for the in-hotel QSO party. I was amazed to work a station in an adjacent state on that arrangement. 73- Nick, WA5BDU toggle quoted messageShow quoted text On Tue, Aug 13, 2019 at 2:50 PM Duane Brayton <dwbrayton@...> wrote: Try to use a bulb that will be near 50 ohms resistance under load.

Re: The Lightbulb QSO Party John T. Fitzer #20283 Please be careful using higher wattage bulbs for dummy loads. I fear someone’s hearing may be damaged if you were to use a 1KW projection lamp with a 1 watt transmitter, not to mention the possible damage to one’s eyes from looking at the extremely bright light. Ah yes I think we may have figured out the answer to the worlds energy, just use a bigger load. 73. 1415926535 toggle quoted messageShow quoted text From: main@4SQRP.groups.io [mailto:main@4SQRP.groups.io] On Behalf Of W6BOW via Groups.Io Sent: Tuesday, August 13, 2019 11:06 AM To: main@4SQRP.groups.io Subject: Re: [4SQRP] The Lightbulb QSO Party Gary, I haven't a final solution to your interesting question.

SSS Results for August John Lonigro #20278 Fellow QRPers: We had 11 participants in the August Second Sunday Sprint, not a bad showing. Most notable is the fact that three of the participants were first-timers: Glenn, N4MJ; David, W0DCX; and Alex, W3AVP. Glenn is from South Fulton, TN. David lives down the highway from me, in Chesterfield, MO. And Alex is from New Holland, PA. Welcome to all three of you. Please participate in the SSS as often as possible. That goes for everyone in the organization. The more participants, the more likely QSOs will be made. Now for the results: The August winner is Nick, WB5BKL, with 17 QSO points, followed closely by Chas, W2SH (15 points) and John, K4BAI (12 points). Nick will be receiving his (digital) certificate in the mail (email) shortly. For the year, Chas, W2SH, is still in the lead with 123 points, followed by Carl, WB0CFF, with 102 points, and Nick, WB5BKL, with 77 points. Chas has a commanding but not insurmountable lead. Several people have a decent chance to overtake Nick for third place and there's an outside chance Carl could either take the lead from Chas or falter and drop a bit in the standings. In other words, don't assume the contest is over. There are still four months to go in the 2019 SSS. 72, John, AA0VE 4SQRP Contest Coordinator

You also want to verify the resistance to ground there (w/ power removed) in case there's a short somewhere. - Dave, K1SWL toggle quoted messageShow quoted text On Mon, Aug 12, 2019 at 8:20 AM K4ENC <K4ENC@...> wrote: Looking some volt reading around Q11 and D 6……………….Q11 running very hot in rec.

Re: Nouveau 75 Errata Dave Benson #20275 Bob- There's clearly leakage current in that area of the circuitry. Dave C's on it, so you're in good hands. 73- Dave toggle quoted messageShow quoted text On Mon, Aug 12, 2019 at 2:37 PM K4ENC <K4ENC@...> wrote: HI DAVE 7.1 V ACROSS R39 NOTHING TO GR. ----------------------------------------- From: "Dave Benson" To: main@4sqrp.groups.io Cc: Sent: Monday August 12 2019 1:16:47PM Subject: Re: [4SQRP] Nouveau 75 Errata The voltage across R39 (10K) should be 0V in receive.

Re: The Lightbulb QSO Party Frank Perkins <N6CES.r@...> #20274 If you go to Lowe's or Home Depot, check out their illuminated bulb display. They have a "vintage" bulb that has a standard size screw-in base, is about 4" tall, and emits an "Amber tint" illumination that looks like a lantern if installed in a "carrage-like" porch light housing. The bulb filament is strung zigzag up and down the length several times in the globe. Long filament. Should be a good antenna. Check it out. 72s Frank N6CES
