Re: The Lightbulb QSO Party
Try to use a bulb that will be near 50 ohms resistance under load.

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 Â

I suspect larger bulb = more filament length and better transmission, just like "the more wire in the air, the better" Jerry, NK2C

With these issues being discussed, is it wise not to install these until a decision is made about a fix, or can one proceed?   I hate to unsolder, because I am not skilled in doing it. JimÂ

SSS Results for August
John Lonigro
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

The voltage across R39 (10K) should be 0V in receive. You also want to verify
 the resistance to ground there (w/ power removed) in case there's a short somewhere.

Re: The Lightbulb QSO Party
Frank Perkins <N6CES.r@...>
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
