QRSS back on the air
"rastk2"
Greetings to all
The HS0ZHB QRSS beacon experiment went quire well. Unfortunately technical difficulties and illness has keep me from getting its counterpart on the air. As of today HS0ZHB has been resurrected as NM7J located in Las Vegas, NV. Using a coaxial bazooka inverted V at APPROX. 35 feet. Final settings are 80mw and everything is working so far. Any feedback would be appreciated. 73 de Stephen NM7J |

Hi Guys....
These might be of interest :- Details of an AVR programmer for USB which you can use to reprogram the ATTiny 13 keyers we provide with the beacon kits -?

30m beacon now operational
timrob@...
Guys
I have activated my 30m beacon at QG62ll. Unknown power but I assume close to 100mW into a 30m dipole. The feed is approx 10m above the ground and the arms are horizontal, one EW and the other NS. On a sloping block so the ends are higher than the feed. Frequency is 10140035, but has varied a little during the day, up to 10140045. I have it running 24/7 until the batteries fail, when I'll replace them. Thanks Tim VK4YEH |

G0UPL Beacon kit availability
Stephen Farthing
Greetings one and all,
I am afraid we are out of stock of beacon kits and a few other items for a couple of weeks until fresh stocks of toroids, crystals and PCBs arrive. I'll post here when we have more stock.
Please do NOT send me money in anticipation of a kit. To keep things easy to manage all orders must go via the shop on Hans's web site.? Thanks, Steve G0XAR -- It is vain to do with more that which can be done with less. |

The Shop works fine
"k6jeb"
Hey All,
Thanks for the words of welcome and by the way, the shop works just fine, I was able to order a QRSS beacon for each of the bands for which the kits are made. Very much looking forward to building them and putting them on the air! I'll be meeting up with at least one of you tomorrow at the NorCal QRP meeting in Pleasanton, CA; see you there Paul. 72/73! Jack, K6JEB |

Hi Hans,

I'm very happy to hear from you. Well OK I misunderstood that PIN #2 outputs AC not DC. I connect the Blue LED with 2.2k-ohm resister into PIN #2. There has no problem until now and it seems working. I agree with your opinion because I'm experimenter not a professional. hi I still QRV every weekend but no grabber catch my 150mW signal. I will continue to QRV on 30m in the weekend. 73,ja9mat hidehiko. On the other hand, I always think if something works, then it is often best not to interfere with it! Many sayings and proverbs mention this! "If it ain't broke, don't fix it!"; "Let sleeping dogs lie" etc. |

Thanks for sharing your fine photos with us! Note that the chip is actually from the AVR family of microcontrollers produced by manufacturer Atmel. Not a PIC from Microchip. Similar functionality, but a different family from a different manufacturer! Another point that I wanted to mention, just from a theoretical basis for your interest: What you say is a 2.5V-DC voltage on pin 2, is not actually DC. It is a 700Hz squarewave AC tone which can be used as a "sidetone". Squarewave with a 50% duty cycle and 5V amplitude. So when you put a voltmeter on there, you would probably see 2.5V indicated. If you connect a blue LED directly to this pin then probably you are running the LED out of its specification. The peak current in the LED is probably higher than it wants, but limited by the ability of the AVR output pin to source it. It's not an ideal situation, though it will light the LED and probably nothing will be too badly abused, so it should not fail. But it would be more theoretically correct to drive the LED on pin 3, via a suitable resistor (e.g. something like 150, or 220 ohms etc). On the other hand, I always think if something works, then it is often best not to interfere with it! Many sayings and proverbs mention this!

QRSS 80 meters - Europe - take a Look
"Ken Evans"
I am QRV on 3500.850. Vern has spotted me in Nova Scotia and SV1BKE's
carrier appears to be above me. So as those of you in Europe wake up, give a look for me and see if we are "crossing the pond". Ken Evans, W4DU QRP ARCI 696, GQRP 5918, FP 295, NOGA, ARRL Life |

QRV 80 meters
"Ken Evans"
I finished the 80 meter beacon last weekend and had a few problems. I first
destroyed a few 2N7000s by turning R8 fully counter clockwise instead of clockwise - read the directions!! Then I could not get the oscillator above 3500.540. I changed turns on L1 several times and finally ended shorting it but could not get above 3500.60. I then changed C9 from a 5 - 25 pf to a 3 to 16 pf. Now I can go up to 3500.860. I think the issue is a finicky xtal. Let me know when you "see me". I currently have my 70 mw beacon on 3500.850 (as close to mid band as I can adjust) Ken Evans, W4DU QRP ARCI 696, GQRP 5918, FP 295, NOGA, ARRL Life |

Re: [qrp-l.org] Don't forget the NoGA Guppy!! A T/R switch...
"Charlie , W5COV"
What I am looking for is a Power Meter , for QRP , QRPp .
A 2 watt and a 1 watt full scale reading would be the ultimate meter , although displaying a little more power would certainly not be a deal breaker . Homebrew is fine too . Don't really need to have an SWR function . The difficult part is I would like for it to operate accurately in the low MF range ( 160 meters , 600 meters ) and also the LF range ( 1750 meters ) . I currently use a clamp on RF probe that works just fine , but it would be nice to have a meter that I can use on the bench , or leave in the line all of the time . ANY design suggestions , or kit devices would be greatly appreciated . THANK YOU , I am SURE someone on this great group , can help me come up with something . Charlie , W5COV Part 15 , Lowfer Beacon : CV , 185.298.25 kHz . , QRSS60 , 24 / 7 , EM26ex , OK. Yahoo Group Moderator , PART15 group , ( no space between part and 15 ) |

Additional info. as follows; Transmit monitor Blue LED is connected to the PIN #2 of the PIC chip. There appears about 2.5V-DC when transmitting. ja9mat Hidehiko. --- In QRPLabs@..., "Hide" <qrper72@...> wrote:

Finished to build QRSS TX
"Hide"
Hi members,
I've finished to build yesterday. I also put some photos in "JA9MAT" photo folder. My Modification are follows addition; 1)The PIEZO monitor speaker 2)The transmittig Blue LED 3)The BCD Switch to change the 8-modes 4)The small heatsink on 2N7000 with EPOXY bonding I use small AC/DC regulator 5V/1A and the Po=150mW without over heating the final-2N7000. I QRV every weekend and hope to catch my weak signal. Thanks for nice QRSS project! 73, ja9mat Hidehiko. |

No problem.

Send me an e-mail once you are ok. I have a beacon that I try to run every night between 1500z (when I go to bed) and 0000z. My signal has been received by ZL2IK already and when I was doing some tests by VK2DI, but now his grabber is offline most of the time. I cannot run the grabber all the time because the computer is also used by other people, but at night and if there "someone" to receive, no problem. Here the address : 73, Yan. --- Yannick DEVOS - XV4TUJ (Blog in french) (web page in english) Le 24 oct. 2010 à 18:45, Hide a écrit :
