Hi Jon The kit requires only the $GPRMC sentence. It will listen to the input data stream and watch for $GPRMC. Anything else, it will ignore. So you can leave in the other sentences or not, it makes

Folks, my Trimble Lassen SKii provides as factory default the following $GPVTG,000.0,T,004.6,M,000.00,N,000.00,K*4C $GPGGA,190341.0,4250.928,N,00240.901,W,1,06,1.78,00593,M,051,M,,*4D I guess I will

Maybe a set of jumpers to support using a common antenna, or using an off-board relay to switch antennas? This way the user would have options for antenna selection. This avoids having to include a

Hans, & others... Might it be possible in some future version of the U-QRSS unit to have the uP use it's FSK ability to switch operating frequency between QRSS and WSPR segments of the band? If that

Hello Hans, Forgot to mention that a WSPR/QRSS tx kit for 500 Khz would be very nice. Did some work on that band (also 136 KHz) and with 1 Watt could reach a 500-600 Km. Did that with a simple 6

Fb Tony, Nice picture and can see very good now what you have made. This way it is very easy to change Capacitors and do experiments. Yes the Magnetic Loop: It is with the size of 150 by 150 cm

How will you manage the fact that the antenna will not present a low impedance to beacons operating at different frequencies? If I was doing that, I think I would give each beacon its own thin

Fb Hans, That is a fb idea! And when a relay from a kit is NOT powered, then the relay contact for TX is switched to a little dummyload/resistor. It can be made a bit foolproof I think, so that

Hi Paul There is already a v1.05, see http://www.hanssummers.com/qrsskitmm.html#Versions What I can do for v1.06, is to use one of the spare I/O pins (labelled F0/F1/F2 on the connector) as an

Thank you Steve. 73, Slim

Paul, I am interested in the idea of the magnetic loop antenna. I wonder how many db down they would be on a big horizontal loop like mine. The advantage of being able to hide it in the loft of the

Hello Tony, Thank you for your answer and your findings! This helps to understand better what the little thing is doing hi. Yes here, (UQRSS 30 M v 1.04 firmware) I did a quick temperature

Interesting findings Paul. I have found that the oscillator frequency is very prone to temperature changes. I have two kits and this is more noticeable in one of them than in the other. I think the

Hi Tony - tnx to you and everyone else for helpful and amusing comments. I've been really busy since resolving my recent problems and haven't had the opportunity to log back into the group. I can

938 WSPR spots in 24 hours with the new 30 meter UQRSS I bought another kit intending to put it on twenty meters. I had 'penned' a crystal down to 14.097 and hoped it would do the job, but I

Steve, ? I think I may have under payed for postage to my United States address. I do hope that my order went out by air, despite my oversight. I remember choosing UK First Class, not knowing what

Hi everyone, Just a quick note to let you know what to expect when you place an order with us for a basic model beacon or an Ultimate one or anything from the shop. I pack orders once a week,

Hi all Many thanks to Luis EA2COA who made a Spanish translation of the "Ultimate QRSS kit" instructions (v1.04). It can be downloaded from http://www.hanssummers.com/qrsskitmm 73 Hans
