Wow, thanks Andy for reporting me! So I guess those long strings of CQs are worth something after all! As with my WSPR transmissions, I often get heard more than I hear.

Nobody on 40 at 1300

Didn't try 1900

Nabbed 3 stations on 40 at 0300, one was a QCX. One called me on the tail end of a QSO, another answered a CQ QCX.

Still fun to do. Spirit of QRP!

Yup only two here as well and only one was QCX.  Several big signals but all running QRO so I did not chase them.  Band was quiet, but propagation was not great.  Lets hope 1900 will be better.

Liam,
Is the power supply disconnected?
In any case I think you need to get the U3 working on its own.
It seems there must be a dead short if a 3 amp fuse blows. Maybe a solder bridge or the BS170 shorted.

Section 2.4 of the manual says it does. And that it is part of the debounce.
If it does not flash then is the pushbutton intermittent?

Re: ProgRock won't program correctly

I am awaiting delivery of an Arduino.  In the meantime I stubbornly keep trying to program the ProgRock via the switches.  (Isn't this insanity?)  I built 2 more Sythesizers, 2 more Prog Rocks.  Of the two  ProgRocks, one programs sometimes (maybe one out of 20 attempts).  I replaced the bcd slide switches with a high quality hexadecimal thumb-wheel switch from my collection in hope that this would resolve the problem.  A SYMPTOM OF THE PROBLEM:  the red led sometimes does not flash for reasons that are not obvious.  I suspect a problem in debouncing the pushbutton switch, but no easy way to test this.   Does anyone know whether or not the red led should blink 4 times every time a digit is entered?   BTW I have grounded the 1pps input pin

Liam Kingsmill <lumetters1@...>
 

Alan, thank you for jumping in with help. 

5 W PA is not connected to the 5 volt supply.  Just the 12.28 volt supply.  With power supply off, the resistance is 3100 ohms, not zero ohms.  (surprised me, also.) 

Happy you suggested  "Remove connections".  I assume you mean remove connections made since the receiver was removed and the 5 watt PA was added.  Meter shows zero ohms when test leads are shorted together.

AN005_LT was my guide to connecting the the U3S to the 5 watt PA.

Prior to taking away the receiver and adding the PA, the combination of receiver and U3S worked normally. 

One idea has come to mind:  The 5 watt PA driver is the U3S PA.   Perhaps there is feedback from the 5 watt PA back to the U3S which causes it to suck too much current.

I will keep you updated on my progress or lack of it.

Re: QCX and QLG1 GPS Receiver Problem

N3MNT
 

You were correct, the GPS was keying the transmitter.  The GPS input and the on board key share an input pin.  if either is activated then the transmitter is keyed when in normal mode.  In beacon mode that is disabled. You should not have the GPS connected to the QCX when operating in normal CW mode.

Appreciated well off topic but fascinating how many flyers are on this forum.
Somewhere I have an old switchbox morse side key with the 2 switches at the top. These were mounted on the right side of the cockpit in most WW2 UK aircraft including Spitfires. I have no idea how they managed to actually fly as well!
I will leave it there

Well since we are well off topic and into aviation, on a flight test in the early 80s the examiner asked me to take him to the Youngstown VOR. Duly tuning and identifying I pointed out that it wasn’t available for navigation. He protested that “sure it is” until I pointed out it was sending TEST. Flummoxed, he asked how I knew that. He was taken aback that I could read the squeaks (some of the older gear is decidedly squeaky) beyond what was marked on the map and I guess I got the grudging equivalent of a gold star for performing the task above expectations - you have to at least pretend you’re listening to the id. 
The moral is that although you can i.d. a properly working VOR, when it doesn’t match your hopefully properly transcribed symbols, there is much confusion. 
The good news is that the newer radios (phew - back to radio) often have decoding options that tell you what’s out there in plain(ish) language.

Re: U3S + 5 watt PA troubleshooting help needed.

Instantly blew a 1 amp, then a 3 amp fuse in series with the U3S 5 V supply.  Measured resistance between 5 Volt U3S input and ground and it is 3100 ohms.
Liam,

The subject says + 5 watt PA. Is this connected to the U3S 5 volt supply in any way?
If it is then it not should be.

Blowing a 3A fuse means a short to ground on the U3 5 volt line. Not 3100 ohms, nearer zero. Remove connections, check again. (Assuming your meter shows zero with test leads connected together.)

Hi all

1300Z: I could not get on air at that moment because I was in the middle of some PCB work

1900Z: 40m only: Two QCX QRP stations (Andy 9A3JH, Zdenek OK2BQN) and two QRO SP1919PS and 9A3JH

0300Z: 40m only: Normally my favourite session but quiet this morning... for a while I was wondering if I was on the right planet... But then worked two QRO stations R4BZ and E74ZH.

Re: QCX and QLG1 GPS Receiver Problem

Bill NF6R
 

Sorry for the slow reply.  I understand know.  I wasn't keying the transmitter, but it sounded like the GPS module was.  Maybe it was.  I plugged it in tonight, turned on the beacon and let it do it's thing.  I saw the clock reset after the first cycle, and I saw where I was received on the next cycle.  From central California, I was picked up all over the US, and even Antarctica!

Thanks for your help,

Bill

Re: QCX and QLG1 GPS Receiver Problem

N3MNT
 

From page 92.  NOTE: the GPS interface is connected in parallel in the circuit, with the paddle. Therefore, you should NOT have the GPS connected, while operating the radio as an ordinary CW transceiver. If you do, the GPS serial data and 1pps will key the transmitter! Disconnect the GPS before using the radio as a CW transceiver.

Re: QCX and QLG1 GPS Receiver Problem

N3MNT
 

Per then manual the gps input shares the connection with the key.  You should not connect an active GPS when the QCX is in normal mode.  It will key the transmitter and if no ant connected fry the finals.  I suggest not connecting the GPS until the radio is  beacon mode.

QCX and QLG1 GPS Receiver Problem

Bill NF6R
 

Hello,
I built both the QCX and GPS Receiver, but there seems to be keying the transmitter, just as if you pressed the micro-switch, every second with the yellow pulse LED .  The red LED comes on when the QCX is powered up, the green LED starts flashing after about 10 seconds, and the yellow LED flashes at the 1 pps rate.  The green GPS LED flashes at the same 1 pps rate, lighting about 1/4 second prior to the yellow LED. 

I happened to have a SWR indicator on the dummy load, and it was flashing with each flash of the yellow LED and I could hear a noise in the headphones.  Is this correct?

I left the GPS Receiver connected to the QCX for about 45 minutes, but the time and grid square was never set.  I have rewired since that test, but haven't tested it.

I manually set the QCX time, frequency, and grad square, and WSPRnet was hearing it.  So the QCX seems fine.

Should I be able to go into the Beacon menu and see the time/location set?  BTW, the time goes to 00:00 every time the QCX is restarted.

Thanks,
Bill KK6RHW
