Hans,  I just ordered a new GPS to go with a recent 2nd clock kit.  I've lost my capability to flash the chips and also ordered a new c1.03 clock chip a few minutes ago. If at all possible could you brogram that chip with the corrected version?  If there's an extra charge for that let me know and I'll take care of it.

The output of the QCX by design is audio! The original message didn't
Curt,

This is the U3 RX, IQ or additional polyphase unit for audio.

Mike,

Do not miss the fact that Stereo Mix is not an option when the soundcard is taking the IQ from the RX.

The output of the QCX by design is audio! The original message didn't mention changing the hardware to output separate audio outputs in quadrature, as that would need some rearranging of components. Yes if one did that, it could indeed feed a 2 channel soundcard to capture I and Q digital samples, using a different circuit board design.

For the benefit of others following this thread, the beta version Hans sent me is working well now.
many thanks again Hans.

Mike, As Nick says you have to use a program like HDSDR. Then pipe the received audio to another decoding program.
This page gives the basics. https://sites.google.com/site/g4zfqradio/hdsdr_receive_digimodes and some examples.

Hi Dave,

It's a matter of how and where we have lived. We are in Michigan too. One daughter and Pennsylvania raised husband (Dr Murphy BTW) Both lived in Massachusetts for a while after their marriage followed by a move to South Carolina. With an inch of snow the police were shutting the roads nut when the officers were informed of their backgrounds they were waved through and went on to work like nothing had happened. On the other hand, I could not function in that summer heat without several years to adjust:)

Staying on the list topic - there is not very much county park picnic table operation here even with QCX radios during winter.

One of those long orange dowels (arrow-like) that we use to mark our driveways (in case we forget where it is) might support one of those GPS antenna thingies. I have used one to make a helically wound antenna (not wound too tight) for some of the higher frequency bands.

73,

When I lived in Kirksville, MO back in the 1960’s I drove across town to work after a one foot snow fall. Everyone was amazed as they had been at the job for almost 24 hours and asked how I got there. I told them I was from Michigan and had jacked my 1966 Mustang up, installed tire chains, and pushed snow all the way across town. No snow plows in Kirksville.

Most SDR# options for I/Q type receivers will not open without the actual receiver connected to the USB, not the soundcard in.

So far, WSJT ver 2.11 and above is the only program I've found who will accept I/Q from the line in.
I'm looking for more options...

Hi All!

Check our my GPS antenna installation - mounted in the shadow of my house on snow stakes, I am still able to track up to a dozen satellites, and I have no problem obtaining a 3D fix with the QRP-Labs GPS receiver module.


Definitely a creative solution, but did you find you couldn't get get a satellite lock with the antenna(s) indoors? With virtually any gps antenna I've put on that module, always indoors, it was able to acquire a 3D fix with no problem.

As far as the topic of snow stakes, as a Michigan native my "love" of snow is best demonstrated by the fact I've lived in sunny Florida for the last 25 years.

Brad,

I grew up on a farm in 'Misery', close to Cape Girardeau, MO. I joined the USAF and was stationed in AZ (Too Hot), North Dakota (Too cold), and then Merced, CA (just right; AKA. Goldie Locks & 3 bears). Never have I seen a 'snow stake'. In ND, the snow fell and was then blown to Canada and back to SD; but no snow stakes. We had the typical 'snow plow guy' clear the driveway between 4-plexes in ND; but no snow stakes. Are 'snow stakes' an East Coast thing? However, I have seen 'snow fences' in Montana.

Do you know the difference between a Snow Man and a Snow Woman?

Hello, Garry--

It's a.) a measurement tool for determining snow depth...

Crap... Just read your post again...  Your probably running off a battery like I did.  No RTS is an error I got using a charge pack / wall wart.  Hans responded to me a couple months back explaining this.  All it takes is a minor and beyond voltage drop below 4.3 volts or something like that for a split second to cause a reset.  Solution was to run a 7805 for the power source (min 7.5 volts at the input, with proper caps on in and out sides).  Less than a dollar solution and it worked!  Hans does have it written up in the trouble shooting guide, just i was too blind to see it.

Re: QCX works, added GPS, no PPS

Viktors Miske KC8CKZ
 

Im yet scrapping up change to get my first 20 meter QCX, but have studied the manual over and over.
YOU CAN NOT have GPS running while in CW mode.  Goes into Xmit mode.
And ya, your GPS should work from the sounds of it, just a set of rules ya have to follow with the design.

QCX works, added GPS, no PPS

Don DeGregori
 

Removed the GPS unit from Ultimate2 QRSS to try it in the QCX. Connected to the 4 correct pins. 5 volts, Gnd, RXD, and PPS. The GPS unit is a EM-406a I used with the Ultimate. I believe it worked while I was using it. On the QXC, I went to Practice mode, then plugged it in. I went to Beacon mode. . I see square pulses on RXD pin. But, just see base line on PPS pin. Red LED on GPS unit. On GPS data I see:
- -- f-- t- s-        
 Maybe the EM-406a is not compatible with QCX ?

I sent you a version v1.03b beta and a long explanation by private email (offlist). That version also fixes the day of the week. As far as I know there are no other issues outstanding, but please inform me if you find any problems.

I have to do a lot of dismantling to replace the chip in my clock so dont want to do it more than I have to thanks.
Channel T1 has stopped working for me , just random jumps in the last number but I wonder if it is a hardware fault now from dismantling.
I will investigate further when we have a more stable firmware to try.
